Launch your productFrequently asked questions
- Are these SEO tools really free?
- Yes. Every tool on this page is free to use with no signup and no usage limits beyond basic abuse protection. The browser-based tools (keyword density, UTM builder, SERP preview) never send your input to a server.
- Do I need an account to use the tools?
- No. The tools are open to everyone. You only need an account if you want to launch your product on Puthusu and get a permanent dofollow backlink.
- What is the dofollow backlink checker for?
- It fetches any public page and shows which of its outbound links are dofollow versus nofollow, sponsored, or UGC. It is the fastest way to confirm whether a directory or listing actually passes SEO value to your site.
