If a site is found to have insufficient content, this means that the site may not have enough text, and/or the site was deemed to be "under construction." To be approved for AdSense and show relevant ads on your site, your pages need to have enough text on them for our specialists to review and for our crawler to be able to determine what your pages are about. Sites that contain mostly images, videos or Flash animations may not be approved. Additionally, sites that consist only of a site template and very little content may not be approved.
Why is it important for your site to have plenty of content? The AdSense program policies are designed to foster a healthy ecosystem that helps protect users, advertisers, and publishers. Our policies prohibit Google ads to be placed on any non-content-based page or placed on pages published specifically for the purpose of showing ads. We use factors such as keyword analysis, word frequency, and font size in order to determine what a webpage is about and precisely match Google ads to each page. Therefore, it's important for sites to have lots of high quality and unique content in order to provide meaningful user experiences and allow Google to serve relevant ads to users.
If your AdSense application wasn't approved due to insufficient content (or for other reasons), you're welcome to make corrections to your application and/or improvements to your site and re-submit your AdSense application for further consideration. Before you re-submit your application, check out our AdSense policies: a beginner's guide and additional tips to help ensure that your site's pages are ready for AdSense.
If you're wondering how to make improvements to your site, remember that there are lots of published sites already, so think about what it is that makes your pages unique. You should aim to create original and relevant content that keeps users engaged and encourages them to visit your site again and again.
