Since July 1, 2019 Google uses mobile-first indexing. This means that the mobile version of your content is used for indexing and ranking. Check the mobile view of your site in Google Search Console to see if your site is optimized for mobile devices. You can also enter your URL in the Google Mobile-Friendly Test to see what needs attention. Some common mistakes are:
- Elements outside of display: Sometimes text or images are displayed too large to fit.
- Text is too small: Your content must be legible, which is often a challenge on a mobile screen.
- Clickable elements are too small or too close together: Design for users with thick stubby fingers!
- Site speed: This is a ranking factor on its own so be sure to check and optimize the loading speed on mobile and desktop.
- Do not hide content: You may want to have simplified versions of your site for mobile. Google has suggested that using a Read More button is ok for hiding content. Beyond that you should include the same content for mobile as for desktop.
