Hi John,

Thanks for your kind review, happy this is of help to you. I did not know about Blue button so I looked it up. Indeed I started SEOInfo with the same need of just displaying information about a page. However quickly I added the more active parts like automatic canonical validation, hreflang validation (a complicated thing!), automatic structured data validation, Integrated Lighthouse , 404 link checker, etc. I want it to identify problems for me without even having to open it.
The sad thing about the Firefox version is that we cannot have the AMP automatic valition, maybe someday :)

Cheers
