Hi InfinityFree,
I am hosting WordPress on InfinityFree, and I am using the AIOSEO plugin for SEO.
The plugin has a feature named SEO Site Score that checks your SEO score. I have a score of 42 (of 100). It’s not working. There is a screenshot.
It means that simple HTML scrapers (like cURL, which AIOSEO probably uses) will not work with our hosting unless they can execute JavaScript and store cookies.
Yoast SEO is fine for adding all the extra tags for SEO. SEO scanners will all likely have the same issue. Fortunately, those scanners are not necessary for good SEO.
