Hi,
We went to https://www.google.com/amp/s/theshaverzone.com/panasonic-arc5-review/ but we got redirected to https://theshaverzone.com/panasonic-arc5-review/. See image: https://ibb.co/7yznQnR.
Yoast does output some data on AMP pages but without having access to a specific AMP we are unable to properly test.
However, Google’s AMP tester URL tool here shows the page is a valid AMP page and makes references to missing schema. See image: https://ibb.co/C59Gggm.
Note, the Yellow caution triangle in the image. If that is what you are also seeing, then Google is alerting you that you have warnings (not errors) on your page. We have outlined those below.
We ran the URL through Google’s schema testing tool here and it shows two sets of warnings.
One set is for the Review schema piece. As Yoast does not output that schema set we can only say to contact your eCommerce plugin author for more information.
The other set is from a HowTo piece. It seems that you are using Yoast to create that, so we will outline the warnings below.
Missing field “totalTime”
The “totalTime” is a field in the How To block near the top that Google would like you to fill out. See image: https://pasteboard.co/J5KxsOb.jpg. If it makes sense for your users to fill it out, please do so. If not, it is OK to ignore it as these are only warnings rather than errors.
Missing field “tool”
Yoast does not have the ability to output this data. However, we thank you for suggesting a feature for the Yoast plugin. We recommend commenting on the feature request below, so you may be kept aware of updates. You may need an account in order to post.
You can see the feature request here: https://github.com/Yoast/wordpress-seo/issues/13260.
In the meantime, it is OK to ignore it as these are only warnings rather than errors.
Missing field “supply”
Same as above for the “tool” issue.
One of image or video must be provided
The warnings of: “One of image or video must be provided” are just that, a warning. Google is letting you know that it recommends that you add an image at each step. BUT you do not have to. This guide explains more:
