Tips for understanding Webmaster Guidelines
To ensure a good experience for users and advertisers, Google publishers are required to adhere to the webmaster quality guidelines. These guidelines provide information about 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 Google advertising programs 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 the webmaster quality guidelines may be removed from the search index, as well as having Google-served ads disabled under this policy. 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.
