Before Google can rank your page for anything, it needs to be able to crawl it, understand what it's about, and know which version of a URL is the "real" one. This module checks the handful of technical basics that make that possible — the plumbing behind SEO, not the content strategy on top of it.
| Element | Plain English |
|---|---|
| Title tag | The clickable headline shown in Google search results and browser tabs. Missing or duplicate titles across pages confuse both users and search engines. |
| Meta description | The short summary shown under your title in search results — doesn't directly boost rankings, but strongly affects whether people click through. |
| Canonical URL | Tells Google which version of a page is the "master" copy when the same content is reachable at multiple URLs (with/without www, trailing slashes, tracking parameters). |
| Canonical correctness | Checks the canonical tag doesn't just exist, but actually points somewhere sane — a canonical pointing to the wrong domain silently tells Google this page's content lives elsewhere. |
| Meta robots tag | A page-level instruction that can exclude a single page from search results even when your site-wide robots.txt allows crawling — an easy-to-miss, page-specific override. |
| H1 heading | The single main heading of the page, which both search engines and screen readers use to understand what the page is actually about. |
Missing or duplicate title tags are one of the most common reasons a page underperforms in search — not because the content is bad, but because Google can't tell pages apart or doesn't know what to show in the results snippet. A stray page-level noindex or a misdirected canonical is even sneakier — the page can look completely normal to a human visitor while being invisible to search engines. These fixes typically take minutes per page but compound across an entire site.
On most CMS platforms (WordPress, Shopify), an SEO plugin like Yoast or RankMath handles titles, meta descriptions, and canonical tags through simple form fields per page. For hand-coded sites, each of these lives directly in the <head> of your HTML using standard HTML meta tag syntax.
Looking for robots.txt and sitemap.xml? Those checks now live in the Robots, Sitemap & Security.txt guide, which includes deeper analysis (like cross-referencing the two) than this module ever had.
