Free SEO tools: robots.txt, DNS, redirects and Google preview
Technical checks with no account and no credits.
Under Tools you get, free and without an account, what people check by hand most often when a site doesn't show up on Google. They don't use credits.
| Tool | What it's for |
|---|---|
| robots.txt tester | Tells you whether Google, Bing or the AI crawlers can access a URL and which line decides it, using Google's exact rules. It also builds a new robots.txt. |
| DNS checker | All of a domain's records, whether its email has SPF and DMARC, and where the site is hosted. |
| Redirects and HTTP status codes | Every hop of a URL with its code (301, 302, 404…) and whether http, https, with and without www lead to the same place. |
| WhatsApp link generator | Your wa.me link with a message, a QR code and a button for your site. Everything is calculated in your browser. |
| Google preview | How your title and description look on Google and whether they get cut off, on mobile and desktop. |
- So nobody uses them to flood other people's sites, each person has an hourly cap (for example, 30 robots.txt checks and 20 redirect checks). If you hit it, wait a bit.
- They only check public websites: never internal addresses, private IPs or ports other than a website's.
- Pasting a robots.txt by hand doesn't count toward the cap: we analyze it on the spot and don't store it.
