SEO Tags

This page gathers five tools for preparing page tags and presentation. Canonical tag generates a tag from an absolute address. hreflang generator composes language links. SERP preview, Title length check and Heading structure help control what a search engine and a reader see. Useful before publishing or during a redesign. Free and no account.

Pick the element you need to check. To avoid competing addresses, start with Canonical tag. For a multilingual site, use hreflang generator. Then SERP preview shows how a result may appear, Title length check measures a list of titles, and Heading structure extracts a document's hierarchy. These tools are often read in that order.

How to use

  1. To avoid competing addresses, start with Canonical tag: use an absolute address and generate the tag to place in the page.
  2. For multilingual content, continue with hreflang generator: compose the links line by line, then check that each declared version matches a real page.
  3. Next, check presentation with SERP preview and Title length check: test title, description and address, then measure a list of titles against SEO bounds.
  4. Finish with Heading structure: extract the H1 to H6 hierarchy of the document and correct gaps or inconsistent levels before publishing.

Frequently asked questions

When should I use Canonical tag?

When the same page is reachable through several addresses and you want to point to the reference version. The tool starts from an absolute address to generate the matching tag.

Does hreflang generator replace translation?

No. It composes valid language links from your lines. It helps declare versions, but it does not translate the content itself.

Why check Heading structure?

Because a clear hierarchy helps readers and search engines understand the page. The tool shows the H1 to H6 levels present in an HTML document.

Can Canonical tag and hreflang generator be used together?

Yes. Canonical tag points to the reference version of an address, while hreflang generator declares language versions. Check that the two logics do not conflict, then review the output with SERP preview.

Why measure titles before using SERP preview?

Title length check helps spot titles that are too short or too long in a list. SERP preview then shows how the result may appear. Use both to adjust title and description without forgetting Heading structure.
