Schema markup and structured data

Structured data is how you explain a page to a search engine in a language it cannot misread. These JSON-LD schema generators produce clean, validation ready markup for articles, products, organisations, tutorials, and FAQ sections, with no coding knowledge required.

Free

Backlink Value Calculator

About these tools

Why people keep coming back to them

Free SEO tools with no signup

Every tool on this page is a free SEO tool in the honest sense: no trial period, no credit card, no email gate. Marketers, agency teams, developers, and business owners can run a keyword clustering job, generate schema markup, or model SEO ROI without creating an account first.

Private by design

The generators and calculators run in your browser. Keyword lists, draft meta descriptions, and revenue figures stay on your device rather than being uploaded to a server, which matters when you are working with client data under an NDA.

Built for international SEO teams

If you run multilingual or multi region websites, the hreflang generator, SERP snippet preview, and schema markup tools are built with international SEO in mind. We work with clients across the US, UK, Europe, and the Middle East, and these tools reflect that.

Ready for AI search

Generative engine optimisation is no longer optional. The llms.txt generator and GEO citability score exist because AI answer engines now sit between your content and a growing share of your audience, and structured, quotable content is what gets cited.

Tools find the problems. We fix them.

Run your site through the tools above, then bring the results to a free consultation. We will tell you which findings actually matter for your business and what we would do about them.
