Blogger lets you share your thoughts, grow your readership, and engage with your audience. But we want to make Blogger even better by letting you tap into the growing Google+ community. Today, we’re adding a new “Google+” tab in the Blogger dashboard, so you now have a central place to start growing your blog with Google+. This means you can now:
Connect your blog to a Google+ profile or page
If you blog under your own name, you’ve already been able to associate your blog with your personal Google+ profile. Starting today, you can now connect your blog to a Google+ page for your brand, business or organization.
Notify followers when you publish, and let them recommend your content
Each time you post on your blog, we'll show you a Google+ share box to let you notify followers that you have new blog content. If they like what you share, followers can +1 or reshare your post to their own friends on Google+. This ripple effect exposes links to your content to a wider audience.
Adding the Google+ gadget to your blog makes it easy for people to add your profile or page to their circles when they like something you’ve published. Forming connections with readers that last after they've left your blog is essential.
To get started, click the “Google+” tab in the Blogger dashboard and then the “Upgrade” button. If you’ve already upgraded to Google+, we’ll help you associate your blog with your profile or page.We'll be introducing more settings on this tab in the future, so stay tuned for additional ways to get more out of Blogger with Google+. If you have questions, you can learn more in our Help Center.
Imagine being able to share your blog with like-minded people across the web. Today we’ve made doing that easier with the introduction of two Google+ gadgets, the +1 button and Google+ Badge.
Unlike the +1 button that can appear below a post, this gadget is specific to your blog. Displaying it on your blog will allow visitors to endorse your blog and share it with their friends. 
+1 button for blog
If you’re wondering what a +1 means, think of it as a public stamp of approval from your readers. As soon as someone clicks on the +1 button next to your blog, they’ll also have the option to share it with their friends, contacts, or the rest of the web.
+1s from your readers will appear to people in their circles whenever your blog shows up in Google search results. Here’s an example:
We’re also introducing the Google+ badge gadget, which allows you to connect your blog to your personal profile or your Google+ page on Google+. Adding the badge to your blog helps you connect with friends, fans, and customers. It enables your readers to add you, or your blog to their circles and follow your blog posts on Google+.
If you are happy to blog under your real name, people can follow your stream on Google+. If you prefer to blog under a nickname or an established pseudonym, you can create a Google+ Page to represent your blog. Bloggers who wish to remain anonymous should continue to blog as usual.
To add these gadgets to your blog, select "Add a Gadget" from the "Layout" tab of Blogger, and select them from the list of gadgets under "Basics". You'll need to copy your Google+ ID (personal or Page) to configure the brand badge gadget for your blog. Add the +1 and Google+ brand badge gadgets to your blog today to grow and engage your audience.
