Technical SEO tools that run in your browser

These tools handle the technical foundations that search engines use to discover, index, and understand your site. A correct robots.txt controls which pages crawlers can access. An XML sitemap accelerates discovery of new pages. Structured data (schema markup) makes your content eligible for rich results — star ratings, FAQ dropdowns, and event cards directly in search results. UTM parameters let you track exactly which campaigns, channels, and content drive traffic, without guessing in Google Analytics. Meta tag analysis catches common issues — missing descriptions, title length violations, absent canonical tags — that silently hurt indexing and click-through rates. Keyword density analysis helps you write naturally and spot over-optimisation before publishing.
