How it works

This service allows you to track web pages for changes based on your keywords. You will be sent an Alert Email, when your defined keyword or keywords show up or appear in a new context (the few words following) since previous Alert.


How to use

Setup your account defining your username, Email-address and password. After signing in, use the Add New Web Alert function to define your desired alerts.

Pressing the Test Web Alert-button shows the recognized keywords with their context (the few words following) within the URL webpage. When any of these change, or when a new appearance of a keyword shows up on the URL webpage, an Alert Email will be sent to your defined Email address.

The defined Alerts are shown in a list

Once a keyword shows up on the defined website or appears in a changed context, you will receive an Alert Email



Keyword syntax

All keywords are case insensitive. keyword abcd also matches for AbCd

keyword
The most simple case. You'll be sent an Alert Email when the keyword (or Keyword or kEyWoRd) appears on the URL in a new or changed context.

keyword1 keyword2
An Alert Email will be sent, if either keyword1 or keyword2 appear in a new or changed context. This can be extended to keyword3 etc.

"word1 word2"
This will be seen as one keyword. They must appear exactly one after as shown word2 after word1.

word1 .. word2
word1 must appear with word2 following shortly after, for the combination to be counted as a match.

word1 .. word2 .. word3
word1 must appear with word2 and word3 following shortly after, for the combination to be counted as a match.

word1 \ word2
word1 must appear without word2 following within the next few words, to be counted as a match.

word1 .. word2 \ word3 \ word4
word1 must appear with word2 following within the next few words, but with neither word3 nor word4 following nearby.

keyword1 | keyword2 | keyword3
An Alert Email will be sent, if either keyword1 or keyword2 or keyword3 appear in a new or changed context. This has the same effect as: keyword1 keyword2 keyword3

John .. doctor \ "New green valley" | xyz .. butter .. "soja milk" \ fat
A more complicated example: The Web URL will be watched for John which must be followed withing few words by doctor, but not by the wording "new green valley". Also searched is the word xyz, followed by butter and "soja milk", but not by fat.


Can I be alerted on any changes of a web page?

webalert.email service does not remember entire webpages. You need to define a keyword, or possibly several keywords, which are likely to pop up on the webpage or will be shown under a new or changed context, meaning the few words following the keyword. When the environment of any of the defined keywords change, you will be alerted. A typical keyword can be the name or main subject of the web page. This is likely to show up within new or changed context if there are significant changes on the web page.

How to stop receiving Emails

In the function Settings, the account can be set Inactive, where Alert Email messages will not be sent.

From function Settings, there is also a link to Cancel account-page, where the account can be removed.


Limitations

JavaScript will not be executed. Page content which is dynamically loaded through JavaScript/Ajax will not be checked. Therefore this service does not work for all web pages.

URL webpages are checked once per day. This limits reaction time to changes in webpages.
