Metadata and SERP preview

The meta tag checker reads a page's title, description and related metadata. SERP preview helps you review a proposed search snippet before publication. A preview is illustrative: search engines can rewrite titles and descriptions.

PageSpeed Insights

Performance results come from Google's PageSpeed Insights and Lighthouse. Desktop and mobile tests can differ. Field data, when available, reflects real-user history; a lab test reflects a single simulated run.

An unmeasured category is not a score of zero. Cached results retain their measurement time, so check the timestamp before comparing a recent website change.

Redirects, robots and sitemaps

Redirect checker follows the response chain and shows its destinations. Robots and sitemap validation helps inspect crawler permissions and submitted URL lists. A sitemap does not force indexing, and robots permissions are distinct from noindex directives.

Structured data

Schema checker reports recognised structured data and validation findings. Valid markup does not guarantee a rich result. Check that structured data accurately describes the visible page.
