AI visibility check

Do4U checks how well a page answers the questions people typically ask about its topic. You give the address of a page or paste a text, and optionally a topic and your own visitor questions. The code splits the page into numbered sections and finds question headings, FAQ markup, the structured data, the llms.txt and robots.txt of the website and the readability. The AI proposes typical questions (yours come first) and rates each one: answered, partly answered or missing. For every answer it must name one section and quote it word for word. The code checks that the section exists and that the quote really stands there, and calculates the coverage in percent itself. Missing answers can be passed on to the FAQ generator with one click. Do4U measures how well the page answers typical questions; how other AI services use the page, nobody knows in advance – this is not a ranking promise.

Who it is for

For website owners, editors, marketing teams and agencies who want to know whether a page really gives the answers that visitors, search assistants and AI services look for.

Typical uses

  • Check a service or product page against the questions customers ask
  • Find the missing answers before you write an FAQ block
  • Compare pages before and after a content update
  • Check FAQ markup, llms.txt and robots.txt for one page in one go

Example

Input

Page text: # Delivery We deliver within Germany in 2 to 3 working days. Orders placed before 2 pm ship the same day. # Returns You can return items within 30 days. Returns are free of charge. Own question: Can I pay by invoice?

Result

How long does delivery take? → Answered (A1): “We deliver within Germany in 2 to 3 working days.” Can I return an item? → Answered (A2): “You can return items within 30 days.” Are returns free of charge? → Answered (A2): “Returns are free of charge.” Can I pay by invoice? (your question) → Missing Coverage: 3 of 4 questions answered = 75%. The missing answer can be sent to the FAQ generator.

Questions and answers

How does Do4U know how well my page answers questions?

The AI proposes typical questions about your topic and rates each one: answered, partly answered or missing. For every answer it must name a section of your page and quote it word for word. The code checks that the section exists and that the quote really stands there; otherwise the answer counts as “unverified” and does not raise the coverage. The code then calculates the coverage in percent from these checked ratings.

Does a high coverage mean that AI services will show or recommend my page?

No. Do4U measures how well your page answers typical questions. How other AI services use a page, nobody knows in advance, so this is not a ranking promise. A page that answers questions clearly is a better basis for readers and for AI services, nothing more.

What does the tool read, and which languages work?

It reads the page you name and, from the same website, only the two files /llms.txt and /robots.txt, at most one request per second. It works in any language: the questions come in the language of the page (or the one you choose) and the quotes stay in the language of the page. The processing takes place on our own servers in Poland, EU.

Is my text stored?

Only as long as needed: 7 days on Free, 30 days with a package – or not at all if you choose not to store it. Processing happens on our own servers in the EU (Poland).

Can I use the result right away?
