Here is an overview of each:
- 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.

Please note I am Dyslexic and in my form I am blind to grammar, and sometimes I get my fors and fours etc backwards. I am not stupid in fact my IQ and EQ are both quite high. Please keep that in mind when you read my blogs. Thanks. You too Google.
