About these tools & data use

Who maintains the tools

The tools and guides are maintained under the Isaivisible name. The site currently offers twelve checkers in English, Spanish and German. You do not need an account to use them, and this build does not provide paid monitoring or live AI mention tracking.

What happens when you check a URL

Your browser sends the URL to our fetch endpoint. The server requests the public response and, for page checks, attempts to read the destination site’s robots.txt. Sitemap discovery may request candidate files and sample up to five children. The tools analyse returned HTML, headers or file contents without executing page JavaScript.

Fetch responses can be cached by the hosting layer for up to 5 minutes. Hosting services may also process ordinary request and operational logs under their own configuration. Submit public URLs only; remove passwords, private access tokens and personal data from URLs before checking them.

Share-card previews may load the declared image directly in your browser. This makes a separate request to the image host. The preview is an approximation and does not establish how any particular platform will render the link.

How to interpret a score

A score summarizes the local checks in that tool. It does not confirm Google indexing, rankings, AI citations, rich-result eligibility or full accessibility compliance. A high score can coexist with problems outside the tested response. A failed heuristic can also need context rather than an automatic change.

The checkers have practical fetch and parsing limits: 3 MB per fetched response, a timeout for each network hop and a 30-second budget for each fetch request, a maximum redirect chain and limited sitemap sampling. A fetch failure describes what our service observed; another crawler may receive a different response.

Reports stay in your browser until you export them

Copying or downloading a report is an explicit action. The text file is generated in the browser and no report database is created by that action. The app does not save your checked URL or report in local storage. A URL may be included in a navigation query when you explicitly continue in another tool or switch language.

A report includes the checked URL and time, so review it before sharing it. If you investigate an issue with another person, include the tool name, observed response and relevant report details. Avoid sending private credentials or complete sensitive page content.

Optional usage statistics

Optional Web Analytics is disabled in this build.

Optional tool events are disabled in this build.

When enabled, the integration removes query strings and URL fragments from known site page addresses and drops unknown paths. Tool events use a fixed list of actions and tool names, language, outcome, grade and broad duration ranges. They do not include the target URL, fetched HTML, report text or raw error message. The hosting provider still receives the ordinary network request needed to deliver the site.
