There are a few configurations you can choose to make your Web site mobile-friendly.
However, there are key points that you should take note of regardless of which configuration you choose to set up.
- Signal to Google when a page is formatted for mobile (or has an equivalent page that’s formatted for mobile). This helps Google accurately serve mobile searchers your content in search results.
- Keep resources crawlable. Do not use robots.txt to block search engines from accessing critical files on your site that help render the page (including ads). If Googlebot doesn’t have access to a page’s resources, such as CSS, JavaScript, or images, we may not detect that it’s built to display and work well on a mobile browser. In other words, we may not detect that the page is “mobile-friendly,” and therefore not properly serve it to mobile searchers.
- Avoid common mistakes that frustrate mobile visitors, such as featuring unplayable videos (e.g., Flash video as the page’s significant content). Mobile pages that provide a poor searcher experience can be demoted in rankings or displayed with a warning in mobile search results. More information in Common mistakes section.
