This is exactly the kind of tool developers and marketers need! A free, no-login SEO audit that covers everything from Core Web Vitals to canonical chain detection is incredibly valuable. The page comparison feature is a standout — being able to benchmark two pages side-by-side saves so much time. The AI suggestions for improving SEO scores are a great touch. Bookmarking this for all my future projects!
The idea for yaSEO came from my own frustration - constantly paying for heavy SEO platforms just to check a single URL. So I decided to build a lightweight, free tool that does exactly what I need: fast technical + content audit, page speed, social previews, and clear recommendations without any login. Simple as that. Feedback is very welcome!
