Whether to monitor for hacking activity, keep an eye on price changes, or get a warning when someone changes something on your site they shouldn't have, there's a place for site change monitoring in your tool box.

Here are 3 ways to do so: offsite, using Firefox, and using Chrome.

#1. SE Ranking

SE Ranking is an off-site, premium subscription tool.

The tool scans elements such as title tags, meta tags, headlines, HTTP responses (301, 404), robots.txt file, etc. It can monitor the number of inbound and outbound links.

Content can be monitor just as text-on-page or, using tags embedded in the content, as text and as HTML.


Scanning frequency can be set as you wish. It's recommended to enable notifications and alerts.


Detailed change logs can be viewed and compared as far back as 6 months.


#2. SiteDelta

SiteDelta works as an add-on for Firefox.

Once installed the extension can show you if, and what, changes have been made to a page since the last time you visited it.


Options available include:

1. Scanning frequency. You can easily set the frequency: weekly, daily, hourly or custom another time.


2. Page information. This section will show you the text-only version of the page from your last visit.


3. Tracking preferences. This feature helps you monitor the change image URLs, all deleted text, ignores cases and numbers and backup changes.


4. Monitor or ignore specific parts of a page:


#3. Page Monitor

Page Monitor is a a Google Chrome extension.

You can monitor a complete page or specific parts of a page using either Selector Expressions or Regex.

Scanning frequency defaults to 180 minutes, but you can set it as you wish. As changes are monitored using your own browsers, realize that checking for changes too frequently can affect your own browsing.clip_image030
