Analysis: see where you stand

The SEO checker audits a page’s title, meta description, heading outline, canonical, robots directives, hreflang and structured data in one report. The Open Graph preview shows how your link will look when shared on Facebook, LinkedIn, X or WhatsApp. The keyword density checker lists the most frequent words and phrases in the text, and the robots.txt tester and sitemap checker confirm that search engine crawlers can actually reach your pages. Running them in that order after publishing is a solid routine.

Generators: correct code without typos

The meta tag, schema markup and robots.txt generators build code that is easy to get wrong by hand, through a simple form. With the schema generator you can create JSON-LD for an organisation, local business, product, FAQ or article. If you are moving a site or changing URLs, the 301 redirect generator writes rules for Apache, Nginx and other servers, and the slug generator turns titles into clean, lowercase URLs with accents and special characters removed.

A practical tip

Blocking a page in robots.txt does not remove it from search results: Google can still index a blocked URL if other sites link to it, just without a description. To keep a page out of the index, use a noindex meta tag and leave the page crawlable so the bot can actually read that tag. Before you publish a robots.txt change, test it with the robots.txt tester, because a single stray rule can block an entire site.
