Questions
What people ask about the tools
Limits, data sources and what each tool won’t do.
Are these SEO tools really free?
Yes. None of them asks for an account or a card. Two have fair-use limits because each run costs us money: the AI Visibility Checker gives you three new categories a day (any category someone checked in the past week opens instantly and doesn't count), and the HTML viewer gives you two free share links, then asks for an email for unlimited links.
Why does an SEO agency give its tools away?
We built them for our own client work first, so keeping them public costs us very little. If a tool saves you an hour, that's the point. If it shows you a problem that needs more than an afternoon, you know where to find us.
How does the AI Visibility Checker rank brands?
It asks one model each from OpenAI, Anthropic and Google, the companies behind ChatGPT, Claude and Gemini, for the top ten brands in your category. A brand gets 10 points for 1st place down to 1 for 10th. Brands named by more models come first, then the table sorts by points. Each category is cached for 7 days.
Does the backlink finder show a competitor's real backlinks?
It opens each competitor in the free backlink reports from Ahrefs, Seobility and Ubersuggest with one click. We don't run our own link index, so the link data comes from those tools. Our part is the plan: searches for nine kinds of link opportunity and an outreach email for each.
Where do the allintitle counts come from?
From Brave's index, fetched automatically for up to 50 keywords per run. Google's own allintitle number is an estimate that changes from day to day, so use the automatic counts to sort a long list, then confirm your shortlist on Google with one click.
How long do links from the HTML viewer stay online?
Seven days, then the page deletes itself. Each page can be up to 500 KB, and published links show HTML and CSS only. Scripts don't run on them, which is what lets us host anyone's HTML safely.
Can you do this work for us instead?
Yes, that’s our day job. The services below are where each tool comes from, and you can book a 15-minute call to talk it through.
