Frequently Asked Questions

What makes SEOLamp different from other SEO tools?

SEOLamp is built by a senior frontend engineer, so it focuses on the technical SEO problems that live in your HTML and code: rendering, canonicals, headings, links, images and speed. Every result explains what to change, not just what is wrong.

Do I need an account to use the free tools?

No. Open any tool, enter a URL and get results in seconds. No sign-up, no card.

How does the Site Audit work?

Enter your domain and the crawler checks up to 250 pages from your sitemap and internal links. A few minutes later you get a health score and every issue ranked by priority, each with a fix. Pay $10 once to unlock the full report and PDF.

Can the tools analyze JavaScript-rendered pages?

Yes. Tools like the heading analyzer, link analyzer and canonical checker have a Render JavaScript option that loads your page in a real headless browser, and tools like Page Speed and Bot vs User View always do. Every tool is free.

Can I get help implementing the recommendations?

Yes. An engineer review is a manual look at your site and code by the senior frontend engineer behind SEOLamp, with recommendations for your stack and code review of the fixes.

What payment methods do you accept?

All major credit cards, through Stripe. If an audit does not work as described, you get a full refund.
