Why we build free tools

Good tools do more than fill a form. They solve a real, repeated job — and the best way to show how we think about SEO and paid media is to hand you something useful, not a brochure.

Each tool here maps to a service we run: the schema generator sits alongside our AI-search work, the ROAS calculator alongside performance marketing. Use the tool yourself, and if you'd rather it was done for you at scale, the matching service is one click away.

Key takeaways: Everything here is free and browser-based. Bookmark this page — it's where every new tool lands. If a tool solves the job but you want it run for you across a whole site or account, the linked service is where we take it further.

Frequently asked questions

Are these tools really free?

Yes. Every tool here is free to use with no signup, no login and no credit card. They run in your browser, so your inputs stay on your device. We build them to be genuinely useful and to show how we think about SEO, AI search and paid media.

Do I need to create an account to use them?

No. There is no account, no email gate and no download. Open a tool, use it, copy your result and go. If a tool ever needs a value from you, it is used only to produce your output in the browser and is not stored.

Which tool should I start with?

Start with the Schema Markup Generator if you want richer search results and to be easier for AI engines to cite. More tools — a SERP snippet preview, a UTM builder and a ROAS calculator — are on the way, each aimed at a specific SEO or paid-media job.

Can I use these tools for any website?

Yes. The tools are not tied to WordPress or any platform. Whatever you build with them — schema code, tracking links, calculations — you can use on any website, CMS or ad account. They are general-purpose utilities for marketers and site owners.

Will you add more tools?

Yes, regularly. This hub is where every new tool lands. Our roadmap includes a SERP snippet preview and meta length checker, a UTM campaign URL builder, a ROAS calculator, a website SEO audit and an AI-search readiness checker. Bookmark this page to catch new ones.
