Frequently Asked Questions

Are these tools really free to use?

Yes, all our SEO tools are completely free to use. We don't hide core features behind paywalls or require account registrations to access the basic utilities.

Do you store my URL data?

No. Tool Studio operates on a strict client-side privacy model. When you paste your website data, URLs, or schema markup into our generators, the processing happens directly inside your browser. We never send or store your proprietary marketing data on our servers.

What is Technical SEO?

Technical SEO refers to website and server optimizations that help search engine spiders crawl and index your site more effectively. It covers elements like robots.txt, canonical tags, XML sitemaps, structured data (JSON-LD), and page speed architecture.

Can I use these tools for client websites?

Absolutely. Our utilities are built for agency professionals and freelance consultants who need to generate white-label deliverables, like CSV exports of keyword mixes or redirect chains, to hand off to their engineering teams.
