Ahead of Google’s upcoming mobile-friendly algorithm change, the search giant is providing advice to site owners on common mistakes to avoid when converting your site to a mobile-friendly design.

In fact, Google sought advice from its own webmaster community on Twitter and compiled a list of the most commonly mentioned mobile mistakes.

Here is an overview of each:

  • Blocked JavaScript, CSS and image files: In order for Googlebot to see your site as a real user would, always allow access to these files in your site’s robots.txt.
  • Unplayable content: This consists of certain types of videos, or other content, that are not playable on mobile devices, such as license-constrained media or media that requires Flash.
  • Faulty redirects: If you have separate mobile URLs, you must redirect mobile users on each desktop URL to the appropriate mobile URL.
  • Mobile-only 404s: Some sites serve content to desktop users accessing a URL but show an error page to mobile users. Instead, redirect mobile users to an equivalent mobile page to avoid 404s.
  • App download interstitials: This is when websites block the view of pages with a prompt to download the site’s native app. Instead, use a small HTML banner at the top of the page.
  • Irrelevant cross-links: This is when users are linked to desktop-optimized pages from the mobile version of the site, and vice versa. Check your links to make sure that they point to the correct equivalent page.
  • Slow mobile pages: In order to avoid user frustration, ensure your mobile pages load quickly. You can check your page speed with Google PageSpeed Insights.
