Built for website change monitoring
Every feature in the website change monitoring workflow is tuned to surface the signals your team actually cares about, and stay quiet about the ones it does not.
Any URL, any change type
Track content, pricing, headlines, links, and page structure on any public URL - a competitor page, your own site, a supplier, or a regulatory page.
Change detection without the noise
A hash pre-check and scored diff filter out cookie banners, ad rotations, and cosmetic tweaks, so you only hear about the changes that matter.
Visual and text diffs
See exactly what moved with a highlighted before/after text diff and a full-page screenshot comparison, on both desktop and mobile.
AI summary and importance score
Every confirmed change comes with a plain-English summary, an importance score from 1 to 10, and the likely impact - so anyone on the team can triage it.
It does not just flag the change. It explains it.
When a meaningful website change monitoring change is detected, SiteGauge sends the diff to Claude and gets back a plain-English summary, the likely impact, and an importance score from 1 to 10, so a junior can triage and a director can act.
- Plain-English summary of exactly what changed
- Why it matters for your business, not just that it moved
- An importance score so you triage the loud signals first
- Included on every plan, even the free one
A monitored page in your website change monitoring workflow just changed. SiteGauge scored it as a high-priority website change monitoring signal, summarised what shifted in plain English, and attached a before/after diff. This looks intentional and worth a closer look, recommend reviewing before it affects you.

Stop doing it the old way
Manual checks and generic scrapers leave you blindsided. SiteGauge turns raw changes into intelligence you can act on.
The old way
Checking pages by hand does not scale, and refreshing a competitor or supplier page every day still misses the change that happened overnight. Generic scrapers flip on every cookie banner and ad rotation, so the real change drowns in noise and you stop trusting the alerts.
- ✕ Manual spot-checks that miss the change that mattered
- ✕ You find out too late, after the damage is done
- ✕ Generic monitors that alert on every trivial edit
- ✕ No idea whether a change actually matters
With SiteGauge
SiteGauge runs a four-stage pipeline on every URL. A lightweight hash check runs first to skip pages that have not really changed, then a scored text diff, then a screenshot, then an AI summary - so you are alerted only when something genuinely meaningful changes, in plain English.
- Alerted the moment a meaningful change lands
- Workflow scoring cuts the noise to a minimum
- AI tells you the likely impact, in plain English
- Before/after diff you can hand straight to your team
