Awesome tool love it so much info and how to fix any problems this kills the paid options out there must have for any developer.
It found issues I had no idea were hurting seo I love this tool!
one of the best seo tool and time saving for my work, thank you
This is becoming the first test I run on my websites. Super fast scan, across 100 URLs, so it catches a lot. Clean interface. Helpful enough that I'm considering the pro version even though I'm not sure I need it yet.
This is a great complement to lighthouse. It's especially useful for catching HTML validity and site security issues. There's only one mild complain (suggestion ^_^) - errors should be graded by severity. For example, having a site title that's 3 characters longer than the suggested max length is not a big deal, while lack of HTTPS or insecure password forms are a big problem. Perhaps warning/error levels could be added?
Easy to use
És molt útil
Actually for once a good free tool! Way more information than the "usual" website analyzers, I might even think about paying for it
Muito útil, nos ajuda a entender o que nosso site realmente precisa para funcionar melhor.
Fantastic plugin!
