Magic in the making: The 4 pillars of great creative

Consumers report that helpfulness is their top expectation of brands since the start of the COVID-19 pandemic, with 78% saying a brand's advertising should show how they can be helpful in everyday life.1 This means businesses need to quickly engage audiences with meaningful messages, using immersive storytelling to bring their brand and products to life.

To help you build visually-rich ad experiences that easily drive consumers to action, we've brought together our top creative guidance across Google Ads solutions in a single guide. Learn to craft stronger calls-to-action, engaging ad copy and striking visual assets — plus, get the latest insights from our team of creative and data scientists at Creative Works. You can also explore tips by marketing objective in order to craft more impactful creative to meet your business goals.

The 4 pillars of compelling creative

Lead with a clear call-to-action:Personalized descriptions perform up to two times better for their campaign goal versus non-personalized descriptions.2 This means businesses need to help consumers immediately see what they have to offer by including words like "you" to draw attention, and adding their product or brand name in headlines and descriptions.

Connect more authentically with a wide variety of assets:Audiences take action faster if they can relate to your message — 64% of consumers said they took some sort of action after seeing an ad that they considered to be diverse or inclusive.3 And images that feature people perform over 30% better for their campaign goal versus images that don’t.4 Given the variety of consumers looking online for new products to try, brands should show a wide range of people using their products or services to resonate with audiences.

Build for smaller screens: Images with no overlaid text, or overlaid text under 20 characters, perform up to 1.2X better for their campaign goal versus images with longer overlaid text.5 With people spending more time on a broad range of small devices, businesses should consider how and where consumers are seeing their ads and provide visual assets that clearly communicate their call-to-action.

Give your creatives time to test: We've seen that waiting 2-3 weeks between changes to ad creative minimizes performance fluctuations, allowing the Google Ads system time to learn and adapt to your most effective assets. Review Ad strength and asset reporting to better understand which assets resonate best and help you make the call on which to remove or replace.

Display campaigns made easy

Helping you connect with customers is core to the Google Ads mission, and we're always working to make that as easy as possible through our products. That’s why, starting this month, we’re bringing the flexibility of standard Display campaigns and the automation of Smart Display campaigns into a single Display campaign. 

We introduced Smart Display campaigns four years ago to create a simple way to reach your audience across millions of sites and apps. Smart Display campaigns have helped make it easier to reach your goals — using automation to find new and existing customers, tailor your creative and set optimal bids.

Then we brought the best of this automation to standard Display campaigns, powering features like responsive display ads and automated bidding — even the option to pay only for the conversions your ads drive. We’ve seen these lead to better business outcomes for advertisers; but we’ve also heard that your priorities can change, and you want greater flexibility to test new features.

In this new Display campaign experience, you’ll have all of the reach and performance you’re used to, with the ability to choose the level of automation you prefer in bidding, creatives and audiences. A smooth setup process will allow you to choose between automation or control up front, and you’ll have the flexibility to change your automation choices at any time — without creating a new campaign.

Whether you choose an automatic or customized experience, Display ads are designed to help you meet your customers in the moments that matter. With that in mind, we've also introduced optimized targeting to Display campaigns to replicate the effortless experience of automatic audience targeting previously available only on Smart Display campaigns. This is an easier option for reaching new and relevant audiences — driving impressions, clicks or conversions to help you meet your goals.

Optimized targeting in the new Display campaign creator

Advanced advertisers can continue to add the manual audience-finding options from standard Display campaigns for more control, or use these audiences in combination with optimized targeting. Optimized targeting will treat audience settings as signals, looking more broadly to find customers that can improve your campaign performance and deliver a better ad experience.

Our top priority is helping you reach your customers with more relevant ads. And with one simplified Display campaign, we’re making it easier than ever.

Keep up to date with the latest Display campaign innovations in the Help Center.

Tools and partnerships to help travel recover and thrive

The travel industry is beginning to show promising signs of recovery as parts of the world reopen and vaccinations continue. We see from Google searches that people want to travel, provided they feel safe to do so: Global searches for “where to travel,” “can I travel” and “covid travel restrictions” are near all-time highs. Google is working hard to listen to customer feedback and ensure travel businesses and tourism officials have the information needed to continue recovery.

That’s why last December, we began testing Travel Insights with Google in the Asia Pacific region; it’s a set of tools providing powerful insights into real-time travel demand based on global Google Search data. Today we’re launching Travel Insights with Google in the United States, in partnership with Destinations International and Hospitality Sales and Marketing Association International (HSMAI). Together, we’ll bring these tools to the travel industry in the U.S. and around the world with training materials customized specifically for destination organizations and hospitality marketing professionals.

Consumer insights to help
accelerate recovery

There are two free tools available within Travel Insights with Google that provide rich data and actionable insights. 

Destination Insights gives travel businesses, governments, and tourism boards a clear picture of top sources of demand per destination. This can help users understand where potential travelers may be coming from and adjust marketing campaigns accordingly. The second tool, Hotel Insights, helps hoteliers analyze search trends so they can understand where interest is coming from and attract new guests by creating a stronger digital presence.

Since we began piloting these tools last year, they’ve helped government tourism officials in places like Singapore and Indonesia answer critical questions as they make decisions about border reopenings. As part of our ongoing global expansion, we recently launched localized versions of Travel Insights with Google in countries across Asia and Europe, including Spain, Greece, France, Italy, Croatia, China, India, Indonesia, Japan, Korea, Malaysia, Philippines, Thailand and Vietnam.

“As we enter into the recovery phase after the pandemic, relevant and timely data will be essential for destination organizations around the world as they will be required to respond intelligently and proactively on behalf of their communities. We are thrilled to partner with Google for this type of information that will help make our members successful.”
—Don Welsh, President and CEO of Destinations International.

“Partnering with Google on this initiative reinforces that what industry professionals need are insights, not just information. HSMAI members that are inspiring marketing will benefit greatly by having access to the exclusive expertise that Google provides on what today’s traveler is searching for as the recovery picks up across travel and tourism.” 
—Robert A. Gilbert, CHME, CHBA, President and CEO of HSMAI

More actionable features 

Based on feedback we’ve heard from our pilot partners, today we’re also introducing new, helpful features within the Destination Insights tool. 

Focusing Facts will allow users who visit Destination Insights to view a set of quick insights such as “Fastest growing destination globally,” “Country with the most inbound interest” and “Top city in demand.” Focusing Facts are based on the previous 84 days of data which provides a well-rounded vantage point.

Responsibly reinvigorating the tourism sector will take ingenuity and effort across the industry. We want to support travel and tourism professionals with the tools and insights they need to connect with people searching for travel. As we make progress toward recovery, we’ll continue to seek to find new ways to support the global travel and tourism sector by sharing data and insights that can help the industry rebound.

In just a few clicks, GoDaddy merchants can show up across Google

Shoppers get the most choice when they can easily discover businesses and their unique products. And when those products get discovered, businesses can connect with more customers. We see it as a win-win, which is why we’re working hard to make commerce more open online. One way we’re doing this is by teaming up with eCommerce platforms like GoDaddy.

Starting today, we welcome GoDaddy online store customers to more easily integrate their product inventory across Google at no additional cost. This means that GoDaddy merchants can now get discovered across Search, Shopping, Image Search and YouTube in just a few clicks. With this integration, GoDaddy merchants can upload their products to Google, create free listings and ad campaigns and review performance metrics — all without leaving GoDaddy’s Online Store.

By teaming up with platforms like GoDaddy, we are able to help even more businesses make more connections with shoppers who are eager to discover new brands.

Conversion modeling through Consent Mode in Google Ads

Last year, we introduced Consent Mode, a beta feature to help advertisers operating in the European Economic Area and the United Kingdom take a privacy-first approach to digital marketing. When a user doesn’t consent to ads cookies or analytics cookies, Consent Mode automatically adjusts the relevant Google tags’ behavior to not read or write cookies for advertising or analytics purposes. This enables advertisers to respect user choice while helping them still capture some campaign insights.

Without cookies, advertisers experience a gap in their measurement and lose visibility into user paths on their site. They are no longer able to directly tie users' ad interactions to conversions, whether the users are repeat visitors or whether those users have arrived from paid or organic traffic sources. To help close this gap, we're introducing conversion modeling through Consent Mode. This will help marketers preserve online measurement capabilities, using a privacy-first approach.

Now, Consent Mode will enable conversion modeling to recover the attribution between ad-click events and conversions measured in Google Ads. Early results from Google Ads have shown that, on average, conversion modeling through Consent Mode recovers more than 70% of ad-click-to-conversion journeys lost due to user cookie consent choices. Results for each advertiser may vary widely, depending primarily on user cookie consent rates and the advertiser’s Consent Mode setup.

How modeling fills in measurement gaps

Conversion modeling can help fill in blanks in media measurement at times when it’s not possible to observe the path between ad interactions and conversions. Conversion modeling through Consent Mode specifically addresses gaps in observable data from regulations on cookie consent in various regions. Conversion modeling uses machine learning to analyze observable data and historical trends, in order to quantify the relationship between consented and unconsented users. Then, using observable user journeys where users have consented to cookie usage, our models will fill in missing attribution paths. This creates a more complete and accurate view of advertising spend and outcomes — all while respecting user consent choices. Conversion modeling also upholds privacy by not identifying individual users, unlike tactics like fingerprinting which Google has a strict policy against.

Using modeling to probabilistically recover linkages between ad interactions and conversions that would otherwise go unattributed means more conversion insights for optimizing campaign bidding and understanding what’s driving sales. It's important for any modeling approach to account for the fact that people who consent to cookies are likely to convert at a different rate than those who don't.

Holistic measurement for your Google Ads campaigns

It’s important for advertisers to have accurate reporting so they can make their marketing investments go further. Advertisers using Consent Mode will now see their reports in Google Ads updated: for Search, Shopping, Display, and Video campaigns, the “Conversions,” “All conversions” and “Conversion value” columns will now include modeled conversions for consent gaps. All other Google Ads campaign performance reports that use conversion data will also reflect the impact from adding in modeled conversions.

Modeled conversions through Consent Mode will be integrated directly in your Google Ads campaign reports with the same granularity as observed conversions. This data then makes its way into Google’s bidding tools so that you can be confident your campaigns will be optimized based on a full view of your results.

Blue pie chart stating: On average, Consent Mode recovers more than 70% of ad-click-to-conversion journeys lost due to user consent choices.

For advertisers who want to optimize their campaigns based on return on ad spend or cost-per-acquisition, they can use Target Return on Ad Spend (tROAS) orTarget Cost Per Acquisition (tCPA) Smart Bidding strategies with Consent Mode. If you had previously adjusted targets to account for cookie consent changes, you can now go back to setting targets in line with your ROI goals. Note that you’re likely to see gradual improvements in reported performance as we recover lost conversions through modeling.

For advertisers who want to maintain their campaign spend, conversion modeling through Consent Mode also works with the Maximize conversions or Maximize conversion value Smart Bidding strategies in Google Ads. We recommend you make sure that the budget you’ve decided on is well-aligned with your spend goals.

Get started

If you’re an advertiser operating in the European Economic Area or the United Kingdom, have implemented Consent Mode and are using Google Ads conversion tracking, conversion modeling from Consent Mode is available for you today.

And if you aren’t using Consent Mode yet, you have two options to get started. You can implement it yourself on your website by following our instructions. Or if you need some extra help, we’ve partnered closely with several Consent Management Platforms, a few of which already take care of critical implementation steps on behalf of advertisers.

We are continuously adding new privacy-forward techniques to help our machine learning solutions better understand the aggregate behavior of non-consenting users, and offer actionable insights in reporting for deeper clarity on your marketing spend. We’ll be bringing conversion modeling through Consent Mode to other Google advertising products, like Campaign Manager 360, Display & Video 360 and Search Ads 360 later this year.

5 new ways Google Assistant can make the day a little easier

Spring is here, and with it, a helping hand from Google Assistant. Today we're introducing five new features that help you tackle small things around the house (and from the car).  

1) Can’t remember where you put down your phone?Don’t sweat it. Already one of the most popular features for Google Assistant, you can tell your Nest smart speaker or smart display, “Hey Google, find my phone,” for all devices, now including iPhones. For iPhones, once you opt in to receiving notifications and critical alerts from the Google Home app, you’ll get a notification and hear a custom ringing sound (even when the phone is on silent or if Do Not Disturb is enabled).

2) Get your takeout faster.Over the last year, more and more people started ordering takeout and delivery on Google, and more restaurants added the “order” button to their Business Profiles on Search and Maps. To make online food orders even easier, Assistant can now help you complete your purchase in only a few steps powered by Duplex on the web. To get started, you’ll need to first search for a restaurant near you from the Google App on Android and select “Order Online” or “Order Pickup.”  When you finish your online takeout order from a restaurant we partner with and click “check out,” Assistant will automatically navigate the site and fill out your contact and payment details saved in Google Pay and synced to Chrome Autofill. At launch, we’re partnering with select restaurant chains and will be adding more across the U.S. later this year.  

3) Try a new sunrise or sunset Routine for your smart home devices.Now available globally, these Routines are based on your  location. For example, you can automatically have your living room lights turn on and the sprinklers start when the sun goes down. It’s easy to set up: 

  • Select the “New” routine tab in the Google Home app or Assistant settings. 
  • Under “how to start,” you’ll need to “add starter,” then you’ll see an option for “Sunrise/sunset.”
  • From there, you can customize the time and specific actions you want them to trigger. 

4) Need routine ideas?Assistant Routines make it easy to automatically perform multiple actions at once with a single command. We’ve included a dedicated section in Ready-Made Routines to highlight popular “suggested actions” to  inspire you, such as “Tell me if my battery is low” or “Tell me what happened today in history.” You can also add a “shortcut” icon to your Android home screen for your favorite Routines. Head to the overview screen for Routines in the Google Home app or Assistant Settings and click the “Add to Home Screen” icon in the top app bar.

5) Have questions about the Oscars?You can get the inside scoop from your Google Assistant. Just ask: “Hey Google, when are the Oscars?” or “Hey Google, who’s nominated for Animated Feature Film at the Oscars?” to hear the list of nominees. To hear some predictions ahead of the red carpet, try “Hey Google, what are your Oscar predictions? or “Hey Google, who do you think is best dressed at the Oscars?” You can also join in on the award night fun by saying, “Hey Google, give me an award.”

Searching for the way forward

I can’t think of a time when technology has been able to be more helpful to more people, families, communities, companies and countries than today. At the same time, the ways that people are using technology are more dynamic than ever. Technology has been a lifeline in lockdown, and it will be an important catalyst in a sustainable and accelerated recovery that works for everyone.

As we strive to emerge from the narrow canyon of restrictions on our lives into a more familiar world of wider horizons, we’re all keen to understand which changes in habits and behaviors will stay with us. What will stick and what will fade? For businesses, the impact of this crisis has varied enormously. Some have seen acceleration, more have had to fight for survival as physical channels to customers were impacted. Whatever the situation, we’re all searching through a fog of uncertainty for the way forward.

At the beginning of the pandemic, we saw how changes were driving businesses to innovate — with many, like Lynsey Pollard’s Little Box of Books, using digital tools to quickly identify and respond to rising consumer demand — in her case for home education resources, tripling website visits in the very first month of the pandemic.

Now, a year later, we can see three big trends emerging that businesses should address to accelerate recovery.

Three lasting consumer trends, as
companies get ready for what’s next

The pandemic has accelerated existing shifts in behavior.

Firstly, we’ve seen that the pandemic has accelerated behaviors which were already underway. Consumers went digital across all aspects of their lives — searches for "delivery," "discount codes" and even "how to" grew significantly compared to the previous years. However, it’s worth noting that some behavior changes remain unpredictable. For example, people’s preference for shopping online over shopping in-store has fluctuated fast and often since May of last year.   

People need more help than ever navigating choice complexity.

Secondly, we’ve seen the value of being fast and helpful for customers. Consumer decision-making is increasingly complex, with more options and considerations than ever. So consumers need more help than ever in making those decisions, giving businesses a huge opportunity to introduce themselves and be helpful at the right moment. 

People want an open and affordable digital world, and that requires relevant ads that respect their privacy.

The increasing importance of technology in our lives has heightened expectations for an open and affordable digital world, underpinned by safety and privacy online. People understand the value of advertising to support that experience and they want to see relevant, timely ads that respect their privacy. 

A Google/Euroconsumers study found that nearly 70% of respondents believe the amount of personal data collected online makes it difficult for them to protect their privacy. Search interest for "online privacy" has grown globally by more than 50% year over year. 

We all have to build trust every time there’s an interaction. People deserve to know how their data is being used so that they can choose to give informed permission.  

More insights and tools for companies to help recovery

So what can we do to help companies face the uncertainty and such dynamic consumer trends? At Google, we’re developing new tools to help businesses understand and respond better to shifting needs. 

Firstly, we’re launching the new Insights Page within Google Ads. It is a new destination in Google Ads where marketers can see contextual and automated insights to help them adapt their business faster in a more dynamic world.

For instance, Body&Fit, an Irish company offering sports nutrition, food supplements and dietary products, was affected by a decline in in-store sales and international shipment delays during local lockdowns. By using health and fitness insights across a number of countries, the brand was able to find new opportunities for growth and even expanded into new markets. As a result, by the end of last year, it saw a 90% year-over-year increase in revenue.

Secondly, we’ve been looking at ways for businesses to move faster — by quickly taking action based on recommendations from our real-time insights, powered by machine learning. To achieve this, we’re taking automation one step further, giving marketers an option to "opt-in" to automatically apply certain campaign and performance recommendations. This means that every time our algorithms detect an opportunity to improve a campaign, brands can implement these recommendations instantly, enabling them to be fast and helpful for their consumers and save time. 

The Netherlands-based agency Dept has been automatically applying recommendations across its client portfolio, and it’s worked — the agency has saved 20% of the time it previously spent on repetitive tasks, while increasing Google ads optimization scores by 18 points on average. Dept has also seen a positive impact on their clients’ performance — construction company BAM saw a 10% increase in conversion volume and a 20% increase in conversion rate.

Finally, as we have seen a decline in trust in online advertising, we’ve been working with the advertising ecosystem on new privacy-preserving proposals open to the industry within the Privacy Sandbox. We’ve also confirmed that once third-party cookies are phased out, we will not build alternate identifiers to track individuals as they browse across the web, nor will we use them in our products. Now is the time for marketers to focus on building strong first-party relationships and the expertise they need to build trust sustainably.

The insights businesses want, the tools they need, the partnership they deserve

As we search for the way forward, businesses need to be even closer to their consumers and respond to their needs faster than ever before. 

Google is here to help turn this challenge into a new opportunity for future growth, by providing the insights businesses want, the tools they need, and the partnership they deserve to help them find the way.

Privacy-first web advertising: a measurement update

In January, we shared how Google’s advertising teams have been evaluating the proposals in Chrome’s Privacy Sandbox, an open-source initiative to replace third-party cookies with viable privacy-first alternatives that can support the publishers and advertisers who help keep the web open and accessible.

Today, we’re going to explain how the latest proposals in the Privacy Sandbox can solve for key conversion measurement use cases on the web while preserving privacy – and we’ll also share a new resource to help you learn more about the overall initiative.

Conversion measurement

Chrome’s conversion measurement proposals center around an API that would have the capability to report both event-level and aggregated information. Event-level information is helpful when businesses need data to be more granular, such as deciding how much to bid on impressions or modeling conversions. Aggregated information is important for summarizing campaign performance, like reporting total conversion value or return on investment.

To make sure that the API preserves privacy, and that any data reported can’t be used to track individual people as they move across the web, the API uses one or more of the following techniques:

  • Aggregate the data that is reported so that each person’s browsing activity and identity remain anonymous among a large group of conversions.
  • Limit the amount of information reported about each conversion, so it’s not possible to expose the identity of the person behind the conversion.
  • Add "noise" to the data reported, which protects an individual’s privacy by including some random data along with the actual conversion results.

The Chrome team recently shared new proposals for how the API could apply these privacy considerations while reporting view-through conversions and cross-device conversions:

For view-through conversion measurement, Chrome proposes that advertisers use the event-level capability of the API to get a report on the conversions that happen on their website and are attributed to ad views across the web. The browser would enable this by registering the ad impressions that take place across websites and then matching any conversions that happen on an advertiser’s website back to the initial views. To prevent any conversion data from being used to track people individually, the Chrome API would limit the amount of information shared about each conversion and add noise to the data. 

Then, when advertisers are interested in reporting on the total number of view-through conversions, for a video ad campaign as an example, Chrome proposes that they can use the API’s aggregate reporting capability. This would allow advertisers to get more precise information on key metrics for the overall campaign without compromising people’s privacy. That’s because aggregate reporting keeps people’s identities and their browsing histories anonymous as it only shares data across a large group of conversions.

For cross-device conversion measurement, Chrome proposes that advertisers use the API’s event-level capability to report on the conversions that happen on their website and are attributed to ad views or clicks that happen on another device. This would only be possible if the people converting are signed into their browser across their devices. Access to this capability would enable cross-device measurement for all participating ad providers and networks.

The proposals in the Privacy Sandbox will change how measurement works for digital ads, but are designed to support key measurement use cases while protecting people’s privacy. We’re beginning to run simulations to understand how different use cases might be impacted by the privacy considerations made in Chrome’s various proposals and we look forward to sharing our findings in the near future.


We know that there are many questions about the Privacy Sandbox and that there is broad interest in learning more about each of the proposals. The Chrome team recently built a new website,, with an overview of this effort, FAQs, and links to additional resources. We’ll also continue to share regular updates about our work across Google’s ads teams to adopt the Privacy Sandbox technologies for our web advertising and measurement products.
