Frequently asked questions
- Are the SEO tools free?
- Yes — every tool here is free with no signup.
- Do you crawl my website?
- No — these tools work on the inputs you paste in. There is no background crawler and nothing is sent to our server.
- Will Google see my generated tags as authentic?
- Yes — the output is the same HTML/JSON-LD Google's documentation recommends. Paste it in your <head> and run Google's Rich Results Test to confirm.
- What schema types do you generate?
- Article, FAQ, Product and LocalBusiness JSON-LD. They follow schema.org's required + recommended properties.
- Are SERP previews accurate?
- Yes — desktop and mobile previews use Google's current pixel widths (~580px desktop, full mobile width) so the truncation point matches what users actually see.
