# Meta Tag Analyzer

> Agent-friendly Markdown of https://www.buildseo.org/free-tools/meta-tag-analyzer — full index for AI agents: https://www.buildseo.org/llms.txt

Audit a page's title, description, canonical, and robots tags in one pass.

## How it works

Enter a URL and the analyzer fetches the page server-side, parses the head, and grades the tags that decide how the page appears in search: title, meta description, canonical, robots, viewport, language, and charset.

Each finding shows the extracted value, whether it passes, and exactly what to change — including character counts against the recommended title and description ranges.

## Frequently asked questions

### What title and description lengths do you check against?
Titles are flagged outside roughly 30-60 characters and descriptions outside roughly 70-160 — the ranges that display without truncation in most search results.

### Does this render JavaScript?
No. It reads the HTML the server returns, which is also what most crawlers index first. If your tags only exist after client-side rendering, that itself is worth knowing.

On-page is half the battle — authority is the other half. BuildSEO AI wins verified backlink placements for your site, end to end.
