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

AI analysisImportance 8/10

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

Website Change Monitoring FAQs

How do I monitor a website for changes?
Paste the URL into SiteGauge, choose how often to check it, and you are done. We capture a baseline, re-check on your schedule, and alert you by email, Slack, Teams, or webhook whenever the page changes.
Can I check a website for changes for free?
Yes. The free plan monitors up to 5 URLs with daily checks at no cost, and our free website change checker tool runs a one-off check without any sign-up.
How often can SiteGauge check a page?
Free checks daily, Standard hourly, Pro every 15 minutes, and Business every 5 minutes. You can set a per-monitor schedule within your plan's limit.
Will I get an alert for every tiny change?
No. A hash pre-check and a scored text diff filter out cosmetic noise like cookie banners and ad rotations, so you are alerted only when a change crosses a meaningful threshold.
What kinds of changes can it detect?
Content and copy edits, pricing and plan changes, new or removed sections, headline and CTA shifts, SEO metadata changes, and visual layout changes - across text, structure, and screenshots.
