Crescade

See your page the way Google and LinkedIn see it

We read the tags in your page's HTML, quote what we found, flag what is missing or broken, and give you a snippet with only the tags you need to add.

Free · a few seconds · no signup · we only read public pages

Secure verification will run before submission.

What it checks

  • Title and meta description, with their length against what search results show
  • Canonical, robots, language, viewport and H1, the basics that quietly break indexing
  • Whether your main content is in the HTML or hidden until JavaScript runs, which is what AI crawlers actually see
  • Open Graph and X card tags that decide how shared links look
  • Every JSON-LD block: valid or not, which types, and which expected properties are missing

We read public pages only, the same way a crawler does, and we do not store your result.

Example output · Missing · og:image

No og:image tag, so links shared on LinkedIn and Slack show a blank card.

Try: a 1200×630 image with your headline on it.

Questions

Does this render JavaScript?

No. We read the HTML your server sends, which is what most crawlers and link previews read first. Tags added later by JavaScript may be missed by them too.

Which schema types should a SaaS homepage have?

Organization and WebSite at minimum. Add SoftwareApplication if the page shows pricing, and FAQPage only when the questions are visible on the page.

I fixed my social preview. Why does the old one still show?

LinkedIn, Slack and X cache previews. Ask LinkedIn's Post Inspector to fetch the page again, or wait a day before re-sharing.

Does title length really matter?

Search results cut titles at roughly 60 characters. Put what you sell first and your brand last, so any cut falls on the part people already know.
