Which markup do you check?

We gather Schema.org, Open Graph and Twitter Card — the three key formats that search engines and social networks rely on.

Can I check many pages at once?

Yes. In list mode, paste several URLs and choose a comfortable speed, from gentle to fast. The number of pages per check depends on your plan.

What does the snippet preview show?

How your page looks in Google and Yandex results: title, description, URL, and for products — price, availability, rating and image. It makes it easy to picture how people will see you.

What does AI analysis give me?

Optionally, AI summarises the findings, offers recommendations and suggests a sample of ideal markup and snippet. It's a paid option, and credits are only spent on a successful analysis.
