Sample report

What your client receives.

One real change record, produced by Crawlens' own detection pipeline. The site is Demo Vapur, a fictional ferry company we built to change on a known schedule, so you can check every line against what actually happened.

  1. Critical

    GA4 and Google Tag Manager are gone

    Both measurement tags were in the last good state and are missing from the new scan. From this moment the page stops reporting to analytics, and nobody notices until the monthly report is empty.

  2. Text

    The fares changed

    The visible text that changed, taken from the stored pages and pinned to the element it sits in. What was removed, then what replaced it.

The marks are the elements the text evidence names, located on each capture. Mobile profile, the same browser and viewport on both days.

Read before you trust it

What this record does not claim.

An evidence product is only as good as what it refuses to say. Three things about this sample, stated plainly.

The price change is not a visual region

Only 428 pixels changed on the page, below the threshold for drawing a visual region, so the engine reports the fares as text evidence instead. The critical verdict comes from the removed tags, not from the price.

Demo Vapur is not a real company

It is a site we built to change on a schedule: fares every day, measurement tags every sixth day. That is why the ground truth is known, and why no real client site is shown here.
