To ensure a good experience for users and advertisers, publishers participating in the AdSense program are required to adhere to the webmaster quality guidelines. These guidelines provide many tips for creating sites that help Google find, index, and rank your site. In general, following these tips will help you to provide a positive experience for your users. The guidelines are quite extensive so we’ve highlighted some important information below:
- Make sure your site adds value. Publishers are not allowed to create multiple pages, sub-domains, or domains with substantially duplicate content.
- Publishers must provide unique and relevant content that gives users a reason to visit their site first.
- Avoid "doorway" pages created just for search engines, or other "cookie cutter" approaches such as affiliate programs with little or no original content.
Please keep in mind that participation in AdSense doesn't affect a site's rank in Google search results and won't queue its webpages for crawling by our main index bots. Publishers wishing to improve their ranking in the search results should visit our Webmaster Central blog and Search Console, which are available to all publishers.
Sites that don't meet these guidelines may be removed from the search index and have AdSense ads disabled. If this has happened to one of your sites, you can modify your site so that it does comply with the guidelines and then submit your site for reconsideration.
