Companies publish before they announce. Filings appear on an investor relations page, a subsidiary is added to a corporate structure document, a leadership page loses a name, a product page changes its terms. Newswires pick some of it up eventually; the page changed first.

How is website monitoring used in investment research?
To shorten the gap between a company publishing something and you knowing about it. Watch investor relations pages, filing indexes, regulatory registers and the corporate pages that reveal structure or leadership changes, and you are alerted the same day rather than when it is aggregated. It is a signal input, not a data feed.
Research teams already know which pages matter. The difficulty is that checking them is a daily chore that scales badly: twenty companies times four pages is eighty manual checks that nobody sustains past the second week.
Automating it changes the economics of coverage. Watching eighty pages every five minutes costs the same as watching one, because the schedule runs regardless — provided the tool is not selling you checks by the thousand.
This page covers what to watch and, importantly, what a change detector cannot responsibly be used for.
Prioritise pages that publish before they are announced.
The listing page where new filings and announcements appear. Watching the index catches a new document the moment it is posted, without needing to know its URL in advance.
Authorisation status, enforcement notices and register entries change without any announcement to the market.
New entities, jurisdictions and subsidiaries appear here first and are rarely announced.
A departure is usually visible on the team page before it is confirmed anywhere else.
For companies you hold or cover, these are the operational reality behind the guidance.
This section matters more here than on any other page on this site.
This is a monitoring tool. It tells you a public web page changed and shows you exactly which words changed. It does not provide market data, it is not a research platform, it makes no claim about accuracy or completeness of any source, and nothing it produces is investment advice.
It is also not a low-latency feed. Our checks run on a schedule from a single origin, at best every sixty seconds on the top plan. If your strategy depends on being first by milliseconds, this is categorically the wrong tool and a market data provider is the right one. What it is good for is the far more common case: knowing the same day rather than the same quarter.
Finally, a monitor can miss things. A page changed and reverted between checks is invisible, a source that blocks automated requests will not be readable, and a document published only as a PDF is watched by its link rather than its contents. Any research process built on this should assume gaps rather than completeness.
Nothing here is investment advice, and no claim is made about the completeness or accuracy of any monitored source. It reports that a page changed, and shows you what changed.
The point of automating this is that it survives a busy quarter.
A filings index catches every new document. Watching individual filings only catches revisions to ones you already knew about.
IR pages carry share price widgets, tickers and rotating banners that change constantly. Selecting the announcements list removes all of it.
Send each analyst's names to their own channel or address. A single shared feed of everything gets skimmed and then ignored.
Every change keeps a dated image and a word-level diff, so a note can cite exactly what the wording was before and when it changed.
Set up same-day alerts on the corporate pages that publish before they announce.
Watch the listing page where new filings and announcements appear, so new documents are caught without knowing their URLs.
Click the listing region so share price widgets and tickers are ignored.
Every five minutes on names you actively cover; hourly for the broader watchlist.
Subsidiary lists and board pages change quietly and are rarely announced.
Per-watch alerting means each name reaches whoever owns it, rather than a shared inbox nobody reads.
Dated before-and-after images and word-level diffs, ready to cite in a note.
Typically about 5 minutes from start to finish.
Uptime monitors, watched pages and heartbeats each get their own allowance, so adding a page watch never costs you a monitor. SSL and domain checks ride along with the monitor they belong to and use nothing extra.

Annual billing is cheaper on every paid tier. The pricing page is the authoritative list.
Every recorded change is compared word by word and kept with a before-and-after image. This is the real output, shown with worked example data.
Price fell from $49 to $39, and an annual discount was added.
The item is available again and the basket button returned.
A new subprocessor was added in another jurisdiction.
The free plan sends to one email address. Every paid plan adds the chat and webhook channels below, with 2 to 10 destinations depending on the plan. However many alerts you receive, the price does not change — nothing here is metered or charged per alert.
There are no voice calls and no SMS. If a phone call at 3am is a hard requirement, say so before you subscribe — we would rather tell you now than refund you later.
Watch the investor relations or filings index page rather than individual documents. When a new entry appears in that list you are alerted with the before and after, without needing to know the document URL in advance.
No, and it should not be used as one. Checks run on a schedule from a single origin, at best every sixty seconds. If your strategy depends on latency, use a market data provider — this is for knowing the same day rather than the same quarter.
No. It is a monitoring tool that reports a public page changed and shows which words changed. It makes no claim about the accuracy or completeness of any source and provides no analysis.
Yes. A page edited and reverted between two checks is invisible, sources that block automated requests cannot be read, and PDF contents are not compared. Any process built on this should assume gaps rather than completeness.
At four pages per name, the $5 plan's 25 watched pages covers about six companies, Growth covers twelve and Pro covers twenty-five. There is no check quota, so watching them frequently costs nothing extra.
Not their contents. Watching the index page catches the arrival of a new document, which is usually the signal, but the text inside the PDF is not compared.
Yes. Alerts route per watch, and team seats give each analyst their own login — 3 on the $5 plan, 10 on Growth, 25 on Pro — without sharing billing access.
If the register is a publicly reachable web page, yes. Registers behind authentication or accessible only through a search form with no stable URL cannot be watched.
