Hi
A. AMP Issue
We went to https://throttlebias.com/performance-vehicles/chevy-camaro-exorcist-specs/amp/ and https://throttlebias.com/performance-vehicles/2020-ford-mustang-shelby-gt500-specs-features-pics/amp/ and we are getting redirected to the homepage. See image: https://pasteboard.co/IDab5Qv.png
Was anything changed on those URLs which would make them redirect? Or can you copy/paste those URLs into a reply?
B. AMP Issue On https://throttlebias.com/performance-vehicles/fastest-mercedes-benz/amp/
Odd. Google is saying there is an issue when you run the URL through the AMP Testing Tool here. See image https://pasteboard.co/IDacI6b.png
Yet when you check on the structured data for that URL, the same result here. No errors.
We suggest the following, which may also resolve structured data issues for the URLs in A above, as Google may be confused.
1. Clear all your caching from your theme, plugin, server, CDN like CloudFlare or browser. If you are not sure how to clear caching from theme/plugin please speak to those authors. If you want to clear cache from the server, please speak to your host provider. To clear the cache from a browser use this guide:?https://kb.yoast.com/kb/how-to-clear-my-browsers-cache/.
2. Delete your sitemap in Google. Doing so will not hurt the SEO of the site. This guide explains more (scroll to the bottom):?https://support.google.com/webmasters/answer/183669?hl=en.
3. Submit the sitemap again. Be sure to submit only sitemap_index.xml and nothing else.?This guide explains more:?https://kb.yoast.com/kb/submit-sitemap-search-engines/.
4. Monitor the results to see if the issue resolves.
C. No FAQ Schema
We can see Google shows no errors here. We can also see Yoast is outputting the page as a FAQpage as expected. See image https://pasteboard.co/IDae51i.png
We suggest trying the action in B above and seeing if the issue resolves.
