As of April 21st Google will be extending the use of mobile-friendliness as a ranking signal throughout mobile search results. This change will affect worldwide mobile search results in all languages, and Google says it will have a “significant” impact. This is a significant step towards delivering primarily mobile-friendly sites in mobile search.
To ensure your site is still appearing in Google’s mobile search results after April 21st, run your site through the
mobile-friendly testing tool. If your site passes, you shouldn’t have anything to worry about.
If your site doesn’t pass, then let us know. We will be able to evaluate your site and get a proposal together to ensure your website is mobile friendly and not penalised in mobile results. You can submit your site using this form: https://dreamscapedesign.co.uk/MobileCheck.
MISTAKES TO AVOID WHEN CONVERTING YOUR SITE TO A MOBILE-FRIENDLY DESIGN
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.
