Site audit

Amplibee runs the page checks that search engines, answer engines and link previews depend on, and says what to change for each one that fails.

The short answer: Amplibee audits the page basics that search engines, answer engines and link previews depend on: HTTPS, title, meta description, canonical link, robots.txt, sitemap.xml, Open Graph and Twitter tags, JSON-LD, heading order, mobile viewport, language and image alt text.

What does the site audit cover?

It looks at the things on your homepage that decide how it is crawled, understood and shared.

  • HTTPS, page title, meta description and canonical link
  • robots.txt, sitemap.xml and whether the page is set to noindex
  • Open Graph tags, the Open Graph image and whether it loads, and the Twitter card
  • JSON-LD structured data
  • Heading order, mobile viewport, page language and image alt text

Why do these checks matter?

Search engines read robots.txt and the sitemap to find your pages. Link previews use Open Graph. Answer engines use structured data for facts about your product. Missing ones make you harder to find or less clear when shared.

What happens when a check fails?

It becomes a gap that says what is wrong, the points fixing it would add and a short guide to the fix.

Can it catch mistakes before launch?

Yes. Founders have found a robots.txt that blocked a folder by mistake and a missing sitemap before launch day instead of after.

Questions people ask

How do I check my robots.txt and sitemap?

Run an Amplibee check. Both are page checks, along with the canonical link and whether the page is set to noindex.

What is an Open Graph image and why do I need one?

It is the picture shown when your link is shared on social sites and in chat apps. Without one, shared links show less than they could. Amplibee checks that it is set and that it loads.

What is JSON-LD structured data?

Machine-readable facts on your page that give search engines and answer engines a clear description of the product.

Why do heading order and alt text matter?

Screen readers and crawlers use heading order to read a page, and images without alt text are skipped by screen readers and image search.

Is it free to try?

Yes. The visibility check is free. Enter your website and you get your score and your gaps. Paid plans add the work Amplibee does for you.
