It looks real flashy, dashy, and super good. That is is. Tried the trial version. Spent about an hour with it. Appears to show some good things bang off but when you try to do ANYTHING, like to start, audit a website, I spin for about 10 minutes with no results. My website has a few pages and is brand new. So it is really not complex. This tool should not be like this. If it is going to work, it should give results immediately.

The extension does not check the currently open page but sends the link to a server which then checks the page. Therefore impractical and unnecessary as an extension.I wonder why they bothered to create an overlay here when a simple link to their site would suffice lol.

Please work on it, just like moz and other platform have extension you can also develop instead of redirection.

A lot of time it does not fetch page size, title, description, headings, meta tag, robots.txt etc. Fix this issue.

It just opens a website, which only lets you make one query before requiring membership. Why does this need access to my browsing history?

It worked like a charm for years, and now suddenly it stopped working and is very buggy. I thought it was because the extension is now paid, so I tried to log in but that didn't even work. Will look for an alternative.

It's great but i'm unable to use it because i like to copy and paste into a spreadsheet. The formatting doesn't work. Detailed SEO Extension nails it for this part.

Decent Site, but the I feel the app needs a bit of work.

The plugin is good with speed but isn't really capable of evaluating SPA application, while doing analysis on my angular web app, the plugin is unable to detect title tag, meta description etc. I imagine the reason could be that it simply requests the page from browser and the server returns the home page of the angular app which doesn't has the real content

If this website checker and it's extension is to be trusted, about 85% of the websites on the internet is at a terrible state. It always shows below 25-30/100 on all websites. It's a great tool to find even the slightest of mistakes tho.
