Website Change Monitor
Websites change without anyone announcing it. A change monitor watches the pages that matter and tells you when one of them meaningfully changes, with the before and after to look at.

Page change monitoring is being built into TagPipes and is not something you can turn on today. This page describes what it is for and how it is intended to work, so you can tell us whether it is the shape you need before it ships.
There is no scan on this page and nothing to run. The form further down is how to hear when it opens.
The pages you did not change are the interesting ones
You know when you change your own pages. What nobody has a good mechanism for is everything else: the template tweak that moved a form, the legal team's update to the terms, the plugin that quietly rewrote your markup, the supplier who changed a specification on a page you link to, or the page that stopped rendering at all after a deploy nobody connected to it.
These are not rare. They are the normal operation of a website with more than one person involved. What is rare is finding out about them on the day rather than in the quarter, and the gap between those two is where most of the cost sits.
A change monitor is a small idea: keep a copy of what a page said, look again later, and tell somebody when the difference is worth a look. Almost all the difficulty is in that last clause.
Which pages are worth watching
Monitoring everything produces noise. These are the pages where a change is usually worth knowing about within a day.
Your pricing page
Everything downstream of pricing assumes it. When it changes, sales collateral, ad copy, and half a dozen landing pages are quietly out of date until somebody notices.
Terms, policies and disclosures
Pages that are changed by people who do not think of themselves as changing the website. A legal or privacy update is often the one change nobody told marketing about.
Key landing pages
The pages campaigns point at. A layout change that removes the form a campaign depends on is expensive for exactly as long as it goes unnoticed.
Pages other teams own
Careers, investor pages, regional sites, anything maintained by a different department or agency. Not suspicion, just distance: there is no reason they would tell you.
Supplier and partner pages you depend on
Specifications, availability, documentation and rates on other people's sites, where you have no change notification at all and no control over the timing.
Pages that break quietly
The ones that fail without anyone noticing: a form that stops loading, a template that empties, a page that starts returning something unexpected after a deploy.
How monitoring is meant to work
The design we are building towards. Not a description of something you can use today.
1. Take a baseline
The first visit records what the page says. Everything after that is a comparison against something, and this is the something. A monitor with no baseline has nothing to tell you on its first run.
2. Look again on a schedule
How often depends on the page. A pricing page changing twice a year does not need an hourly check; a competitor's availability page might.
3. Decide whether the difference matters
This is the hard part and the reason most change monitoring gets switched off. Timestamps, rotating testimonials, view counters, session tokens and advertising change on every single load and are never what you meant.
4. Show what changed, not that something did
An alert saying a page changed makes you go and look. An alert showing the sentence that changed means you often do not have to. The second one is the product.
Watching a site against watching a page
Two different jobs that use the same underlying technique.
| A set of pages across a site | One page, closely | |
|---|---|---|
| The question | Did anything change among the pages I care about? | What exactly changed on this page, and when? |
| How many | Tens. Your important pages, not every page you have | One, or a small handful |
| How often | Daily is usually plenty | As often as the page actually moves |
| What you want back | A short list of which pages moved | A side by side of the old text and the new |
| What kills it | Too many pages, so the daily summary is never empty and stops being read | Too sensitive, so a rotating testimonial counts as a change |
If you are watching one specific page rather than a set, the page change monitor page covers that case in more detail.
What is deliberately not on this page
No pricing, because it is not priced. No screenshots of the interface, because what exists is not finished. No customer counts, no benchmarks and no case studies, because a product that has not shipped does not have any.
TagPipes today does tagging automation, measurement, server-side event delivery, consent management and privacy tooling. The free trial gives you those. It does not give you page change monitoring, and nothing here should be read as saying it does.
