What eCommerce teams monitor with SiteGauge

Every scenario below works on the Free plan. Paid plans unlock faster checks, screenshots, and team collaboration.

Competitor product price monitoring

Track price changes on competitor product pages. SiteGauge scores currency figures and pricing keywords as high-priority signals so small edits don't slip through.

Promotional banner & offer tracking

Detect when competitors launch promotional banners, discount codes, free shipping thresholds, or bundle offers on their category and home pages.

Availability & inventory signals

Monitor product pages for stock status changes, out-of-stock notices, and back-in-stock announcements that signal supply or demand shifts.

Own site change protection

Get alerted if prices on your own pages change unexpectedly - useful for catching feed errors, pricing tool bugs, or A/B tests that went live unintentionally.

It does not just flag the change. It explains it.

When a meaningful change is detected on a page you watch, SiteGauge sends the before/after diff to Claude and gets back a plain-English summary, the likely significance, and an importance score, so a junior can triage and a ecommerce lead can act.

  • Plain-English summary of exactly what changed
  • Why it matters for your team, not just that it moved
  • An importance score so you triage the loud signals first
  • Included on every plan, even the free one

From URL to insight in two minutes

No agents, no proxies, no code. Paste a URL and you are monitoring.

01

Add the URLs you care about

Paste any public URL a ecommerce team tracks. Choose the monitoring workflow that fits, so the signals that matter are weighted above ordinary body copy.

02

We watch continuously

A cheap hash check runs first; a full render, screenshot and AI analysis only fire when a real, scored change is confirmed. Checks every 15 minutes on Pro, daily on Free.

03

You get the why, not just the what

An alert lands in email, Slack, Teams or a Google Sheet, with an AI summary, an importance score and a before/after diff you can act on.

Stop finding out when it is already too late

Checking by hand misses the change that mattered. SiteGauge tells you the moment it ships.

The old way

Why ecommerce teams miss critical changes

A competitor drops the price on a key product by 15%. They run a flash promotion over the weekend. They mark a bestseller as out of stock. These changes move buyer decisions - and if you find out hours late, the sale is already gone.

  • Manual spot-checks that miss the update that mattered
  • Changes surface days late, after the opportunity has moved
  • No idea whether a change actually matters

With SiteGauge

Intelligence, not just alerts

SiteGauge's pricing intelligence workflow is tuned to detect currency figures, promotional copy, availability language, and discount signals as high-priority changes. Your trading team gets an alert within hours - often the same day - with an AI description of exactly what shifted.

  • Alerted the moment a watched page drifts
  • Scored changes cut the noise
  • AI tells you the likely significance
  • A before/after diff you can hand straight on

eCommerce monitoring FAQs

Can SiteGauge track prices on Amazon or major marketplaces?
SiteGauge monitors any publicly accessible URL. Marketplace pages (Amazon, eBay, etc.) work, though dynamic pricing widgets may require include selectors to focus on the relevant price element.
How does SiteGauge handle pages with hundreds of products?
Each monitor watches one URL. For category-level monitoring, add the category page as a monitor. For individual product tracking, each product page is a separate monitor.
Can SiteGauge alert my team via Slack?
Yes - Slack alert rules let you route specific monitor alerts to specific channels. Your trading desk can have a #price-alerts channel updated automatically.
What if the price is loaded dynamically via JavaScript?
SiteGauge uses a full JavaScript-enabled browser (Playwright) to crawl pages, so dynamically loaded prices are captured. If a price is hidden behind a login or personalisation layer, it may not be visible.
Can I monitor my own pricing feed for errors?
Yes - use the website protection workflow on your own product or category pages. An unexpected price change on your own site triggers an alert just as it would for a competitor.
