FAQ
A website change monitoring tool automatically watches web pages for updates and alerts you when something changes. Instead of manually revisiting pages, the software takes regular snapshots, compares them, and notifies you of any differences - from text edits and price changes to structural redesigns. SiteGauge goes further by using AI to explain what changed and why it matters.
Website change detection works by periodically fetching a page and comparing it to a previously stored snapshot. SiteGauge uses a two-stage pipeline: a lightweight content check runs first, and full screenshots plus AI analysis only fire when a genuine change is confirmed. This eliminates false positives caused by ads, timestamps, or dynamic page elements.
Teams use website monitoring software to stay ahead of competitor moves, protect their own site from unauthorised changes, track regulatory updates, and automate SEO audits. Common use cases include monitoring competitor pricing pages, watching for feature launches, tracking supplier terms, and alerting on broken layouts - all without manual checking.
The most reliable way to monitor competitor website changes is with a dedicated tool that watches specific URLs on a schedule and alerts you in real time. SiteGauge lets you add any competitor URL - pricing page, features page, homepage - and receive instant alerts with AI-written summaries explaining what shifted, so you can act before your team even notices.
Yes. Website monitoring is a powerful SEO tool. You can track your own pages for unintended title tag, meta description, or canonical changes that could tank rankings - and watch competitor pages for content updates, new keyword targeting, and structural changes that signal a shift in their SEO strategy. SiteGauge's SEO monitoring workflow is built exactly for this.
Uptime monitoring only checks whether a site is online or offline. Website change detection watches the content itself - text, prices, layouts, metadata. SiteGauge does both: it alerts you if a page goes down, and separately notifies you of any content-level change on pages that are still live.
SiteGauge detects text additions and removals, price changes, navigation updates, new product or feature announcements, meta tag changes, page structure changes, and visual layout differences. You can also configure ignore rules to filter out noise like cookie banners, rotating ads, or live timestamps so only meaningful changes trigger alerts.
Add your competitor's pricing page URL to SiteGauge and set your check frequency. The moment any pricing text, plan structure, or CTA copy changes, SiteGauge detects it, captures before/after screenshots, and sends an alert with an AI summary explaining exactly what shifted. No manual checking, no spreadsheets.
Free plan: daily. Standard: hourly. Pro: every 15 minutes. Business: every 5 minutes. You can set per-monitor overrides within your plan's limit. For time-sensitive pages - like competitor pricing or regulatory portals - Pro's 15-minute checks mean you're never more than a few minutes behind.
No. SiteGauge is entirely cloud-based - no browser extensions, no SDKs, no scripts to deploy. Paste a URL, choose your alert channel, and you're monitoring in under 60 seconds. If you do want to integrate programmatically, a read API is available on Pro, and full read/write API access on Business.
