You can choose to be notified when a word/phrase is either added or removed from a web page, or you can choose to monitor only a specific part of a web page by visually selecting a target element.

If you'd like to be notified when a word or phrase is added to a web page, please select the first option from the notification type dropdown and enter your word or phrase (case insensitive) in the next box.

If you'd like to be notified when a word or phrase is removed from a web page, please select the second option from the notification type dropdown and enter your word or phrase (case insensitive) in the next box.

If you'd like to be notified when a specific part of a web page changes, please select the third option from the notification type dropdown and click inside the next box to launch the element picker. A new window will then open. Give it a couple of seconds to load your page. You can then hover your mouse pointer over the section/element you are interested in and simply click to choose the highlighted area shown in yellow and red as your target element.

If you'd like to monitor an RSS feed for new items, select the 4th option from the notification type dropdown. For Atom feeds, please change the XPath to /feed/entry[1]/title

// TIPS & TRICKS //

Too many emails: If you are getting too many emails, please select a less frequently changing element which is at a deeper level or, you can simply increase the check interval time to either 'Every day' or 'Every week'.

Multiple terms: If you would like to monitor for the addition or removal of multiple terms on a page, you can specify the terms in a comma seperated string and append either {any} or {all} to the end of the string to tell the system to either match any of the terms or all of the terms. For example, to watch a page for the removal of both the terms "out of stock" and "preorder now", you can enter the string: out of stock ,preorder now {all}

Change highlighting: If you would like to disable the green and red diff style change highlighting, please append {nodiff} to your XPath. For example: /html/body {nodiff}

Sorting elements: If you'd like to sort the matched elements in ascending order, you can append {sort} to the end of your XPath. For ex: /html/body/table/tr {sort}

JSON to XML: You can convert a page that returns a JSON result to XML on the fly and use an XPath for selecting desired elements by appending {jsontoxml} to the Xpath. For this to work, you must create a monitor as a RSS type monitor.

Posting data: Pages are fetched using "GET" requests by default. If you'd like us to fetch a page using a "POST" request by posting some data, simply append your data to the end of the URL like so:
http://website.com/seach?postdata=parameter1:value1,parameter2:value2
For example if you want to monitor a UPS tracking page, append the post data to the URL like so:
http://wwwapps.ups.com/WebTracking/track?postdata=trackNums:1234567890,track.x:Track
If you don't know how to use Chrome Developer Tools to sniff out the post parameters in order to construct a working URL for posting data, please ask in the comments below.

Blocked websites: If ChangeMon has been blocked by your desired website from accessing their servers, please let us know in the comments section below and we will add it to our list of sites that should be accessed via a proxy server.

Export Monitors: If you would like to backup your monitors to a CSV file for safe-keeping, please Click Here!

Hidden elements: If the element you are interested in cannot be visually selected by the element picker due to it being hidden from view, you can do the following to setup a monitor for that page element:

  1. Open your desired page in a new Google Chrome tab
  2. Right click on the element you are interested in. Then click "Inspect Element"
  3. Right click on the highlighted blue line. Then click "Copy XPath"
  4. Paste the XPath you copied previously in to the XPath field on the above form.
  5. Fill up the rest of the fields as usual and click "SAVE". That's it.
