Used this on my WooCommerce store and found 12 critical issues I had no idea about. Missing product schema fields, duplicate meta descriptions across variants, and my store was blocking AI crawlers completely. The report came in 48 hours with everything I needed to fix it. Great tool.

everything the tool suggested is completely off. I think that the tool was not able to scan the website at all and therefore made all kinds of non-sense recommendations.

Interesting approach to SEO analysis. Good for quick checks on smaller sites.

Text/image/code/chat in one tool without a sharp wedge = buyers see you as replaceable → usually 30%+ drop in paid conversion vs specialized tools. Why would someone pay you instead of using 2–3 better single-purpose tools?
