Track Changes on a Webpage
Tracking changes on a webpage sounds simple: save a copy, compare it later. In practice most pages change constantly in ways nobody cares about, such as dates, rotating offers, cookie notices and “recommended for you” blocks, so a raw comparison buries the one edit you wanted. RivalPeek.io narrows the comparison to what you describe and keeps a record of each real change.
Choose what to track
Start by deciding which kind of change you are waiting for, because each has its own rule:
- Wording in a paragraph or section: “Tell me when the refund section changes.”
- A word or phrase appearing or disappearing: “Tell me when ‘sold out’ disappears.”
- A number crossing a limit: “Alert me if the waiting time goes above 30.”
- A price moving: “Tell me when the price drops.”
- New entries in a list: “Tell me about new job posts in Singapore.”
If you really want every edit, “Tell me about any change” works too, but expect more alerts.
How it works
- Paste the page address and describe the change in one sentence.
- Review the proposed rule, the part of the page it covers and what it reads now.
- Approve the watch. The current reading becomes the starting point.
- Each check compares against the last good reading; a match sends an alert and records the change.
How noise is kept out
Text comparisons skip short self-updating lines: clocks, “updated 3 minutes ago”, bare counters, cookie banners and language menus. Watching a single section removes most of the rest. If a check cannot read the page, because the site is down or blocking visits, that is recorded as a check problem and the last good reading is kept, so an outage never looks like the content being deleted. After repeated failures over several hours you get an email that the watch stopped working.
What cannot be tracked
- Pages behind a login, and results that only appear after typing into a search form and submitting it.
- Visual-only changes such as images, layout or colors.
- Content that needs clicks to reveal, like a tab or “show more” button, unless it is already in the page.
- Some sites that block automated visits. A browser fallback helps on supported pages, but access is not guaranteed.
The review tells you up front when a page is a poor fit, so test the exact page before relying on it.
Which plan fits
Starter covers 20 pages checked every hour with email alerts, which suits a short list of pages. Pro covers 150 pages checked every 15 min and adds Slack and webhook alerts. Business covers 500 pages checked every 15 min for larger watchlists.

Choose your monitoring capacity
Choose a plan for the pages you need to follow. Starter costs USD $19/month for 20 pages, with ordinary checks every hour. Annual billing is USD $190/year. Pro costs USD $39/month for 150 pages, with ordinary checks every 15 min. Annual billing is USD $390/year. Business costs USD $99/month for 500 pages, with ordinary checks every 15 min. Annual billing is USD $990/year. These are scheduled checks, not a live stream; availability and the check queue can affect when a result arrives.
Pages requiring protected checking use a separate allowance and a slower schedule. Access is not guaranteed, and some sites block automated visits. Start with a representative public URL and review the result before expanding your watchlist.
Frequently asked questions
Can I see exactly what changed?
Yes. Each matching change is saved with the wording before and after, or the old and new values, and stays on your Changes page so you can look back at earlier edits.
Can I track just one part of a page?
Where the page has readable sections, the review offers them and you can pick one. If that section later disappears, the check reports a problem instead of quietly watching the whole page.
Does it compare screenshots?
No. RivalPeek.io compares the readable text, prices and lists on the page, not pixels. A purely visual change, such as a new image or color, is not detected.
How often is the page checked?
Ordinary checks run every hour on Starter, every 15 min on Pro, every 15 min on Business. Each plan also includes a number of manual checks per rolling 24 hours.
