What a page monitor captures

A page monitor does more than tell you something changed. Every confirmed change on the page comes with the evidence to see what moved and decide whether it matters.

A fresh screenshot

When a change is confirmed, SiteGauge loads the page in a real browser and captures it, so you see the page exactly as it looked when the change was caught.

Visual change monitoring

A before and after visual diff

Compare the old and new screenshots with slider, side by side, fade, and difference-overlay views. Desktop and mobile capture is available per monitor.

Screenshot comparison

A track-changes text diff

Every added, removed, or edited line of the page content is highlighted inline, so you can read exactly what wording moved without hunting for it.

URL monitoring

SEO and metadata changes

Title, meta description, H1, canonical, meta robots, schema markup, and hreflang are tracked even when the visible body of the page is unchanged.

Track SEO elements

A plain-English AI summary

SiteGauge categorises the change, scores its importance, and explains what moved and why. AI summaries are on every plan and never metered.

An alert on your channels

Email on every plan, plus Slack, Teams, Discord, Telegram, webhooks, Google Sheets, and SMS from Standard up. An RSS feed is available on every plan.

Change alert workflow

Set up a page monitor in three steps

Pointing SiteGauge at a page takes a minute. From there it runs on its own and only speaks up when there is a real change to report.

01

Point a monitor at any page

Paste the URL of the single page you want to watch. Each page becomes its own monitor with its own change history, separate from every other page you track.

02

Choose the part to watch

Track the whole page, or use CSS selector rules to target just one section, and exclude the parts that always change, like a cookie banner or a rotating hero.

03

Set the frequency and let it run

Pick how often the page is checked, from daily to as fast as every 2 minutes by plan. When a real change is confirmed you get a screenshot, a diff, and an alert.

Watch just the section that matters

Most pages have parts that never sit still: a cookie banner, a rotating hero, a live visitor count. With CSS selector ignore rules you decide exactly what a page monitor pays attention to, so a reworded footer never wakes you up but a price change does.

  • Include a single section, like a pricing table or an announcement block, and ignore everything else on the page.
  • Exclude the noisy parts that always change, so alerts stay meaningful instead of constant.
  • On top of that, every change is scored for importance by AI, so a trivial edit stays quiet and a real one stands out.

Ignore rulesExample
Track.pricing-table
Ignore#cookie-banner
Ignore.hero-carousel

Only changes inside the tracked selector raise an alert. Everything in an ignore rule is filtered out before the diff.

Choose how often each page is checked

A page monitor is not a live stream and does not send push notifications. It checks on a cadence set by your plan, and you are alerted as soon as a check confirms a genuine change. Faster plans check more often.

A page monitor is not a domain crawl or a one-off checker

These three do different jobs. A page monitor is the right tool when you want one page watched over time, with a full history you can look back on.

This page

A page monitor

Watches one page, or one section of it, on a schedule. It keeps a full history of every change with screenshots and diffs, and alerts you when something moves.

You are here
Standard plan and up

A whole-domain monitor

Tracks a whole site or sitemap with a tiered per-page cadence, and can add new pages automatically. Under the hood each page is still its own page monitor.

Website monitoring
Free tools

A one-off page checker

Takes a single snapshot right now with no schedule and no history. Handy for a quick look, but it will not tell you when the page changes later.

Free checker tools

Who tracks single pages

Anyone who has one page that must not change quietly. Start with a page monitor, then scale up to whole-site monitoring when you need it.

SEO specialists

Watch one high-value landing page for a stripped canonical, an added noindex, or a rewritten title, weeks before it surfaces in Search Console.

Competitive and product teams

Track a rival pricing or feature page and share the history with unlimited free read-only viewers, so the whole team sees the same change.

Content and legal owners

Keep an eye on a terms page, a policy, or a supplier's spec sheet, and get a track-changes diff the day a single clause or number is edited.

Stop reloading that one page by hand

Checking a page yourself works until the day you forget. A page monitor never forgets.

Checking by hand

  • x Open the page and squint for what moved
  • x Notice the change days after it shipped
  • x A generic diff tool pings on every reworded line
  • x No screenshot, no history, no idea if it matters

With a page monitor

  • The page is checked automatically on your schedule
  • Alerted as soon as a check confirms a real change
  • Selector rules and AI keep trivial edits quiet
  • Screenshot, diff, and full history on every change

Page monitor FAQs

What does a page monitor do?
A page monitor watches a single web page and tells you when it changes. You point SiteGauge at one URL, choose whether to track the whole page or just a section of it, and set how often it is checked. When a real change is confirmed, SiteGauge captures a screenshot, produces a before and after visual diff and a track-changes text diff, writes an AI summary, and sends you an alert.
How is a page monitor different from monitoring a whole website?
A page monitor tracks one page, and each page you add is its own monitor with its own change history. Whole-domain or sitemap monitoring, available from the Standard plan up, tracks many pages of a site at once with a tiered per-page cadence and can pick up new pages automatically. Under the hood each page in a domain crawl is still tracked as its own page monitor, so the history and diffs work the same way.
Can I monitor just one section of a page?
Yes. You can use CSS selector rules to include only the part of the page you care about, such as a pricing table or a single announcement block, and to exclude the parts that always change, like a cookie banner, a carousel, or a live counter. Targeting the right section cuts noise so you are only alerted when the content you actually care about moves.
How often does a page monitor check for changes?
It depends on your plan: daily on Free, hourly on Standard, every 15 minutes on Pro, every 5 minutes on Business, and as fast as every 2 minutes on Enterprise. A lightweight check runs on that schedule, and a full browser render and screenshot only fires when that check confirms a change, which keeps monitoring cost efficient.
Is a page monitor real-time?
No, and we will not pretend otherwise. SiteGauge checks each page on a schedule rather than continuously, and there are no push notifications and no instant-detection promise. As soon as a scheduled check confirms a genuine change, you are alerted. On faster plans checks run more often, as frequently as every 2 minutes.
What do I get when a monitored page changes?
A fresh screenshot of the page, a before and after visual diff you can view as a slider, side by side, fade, or difference overlay, a track-changes text diff of the content, and an AI summary that categorises the change and scores its importance. That lands on your alert channels: email on every plan, plus Slack, Microsoft Teams, Discord, Telegram, webhooks, Google Sheets, and SMS from the Standard plan up, with an RSS feed available on every plan.
How is this different from a one-off page checker?
A one-off checker takes a single snapshot now and stops there, with no schedule and no history. A page monitor keeps watching on a schedule and stores every change over time, so you can see what moved and when. If you just want a quick single look, our free tools can do that; a page monitor is for ongoing tracking.
Does a page monitor work on pages behind bot protection?
Often. Residential rendering reaches many Cloudflare and Akamai protected pages that ordinary scrapers cannot. It is not guaranteed on every site, since hard anti-bot systems can still block a request, but coverage of protected pages is a core strength.
