Webpage Update Notification
-- An advanced checker to notify changes occurred between visit

I would like to have a program which can keep track of different webpage. When the pages change, there is an alert/popup which will notify me. It is useful to track changes like new replies in particular boards, site news, version update news etc.

However the problem is a single unrelated change in a page would trigger the notification. For example, a random ad in the forum which will always trigger the alert. I wonder if the check can be more advanced. For example:

• alert only when the selected part of the webpage is updated
• decide the threshold on how many changes are needed to trigger the alert (helpful to prevent small unrelated changes from mis-triggering)

Do you have any program you can recommend?
I can pay for the program as long as it is powerful and suit my needs.

A bunch of free ones on Google. I read about one in the past but I can't remember which one it was.

Google is your friend!

Will an RSS reader work?

There is an addon for Firefox that does that. Go to the addons page and look at the most popular addons, I'm positive it's in the first 10 pages.

RSS will only work if the site provides one.
Also it doesn't let you to choose what you want to monitor.
You can't just keep track of one page only if the author doesn't offer you such a RSS.

Googled already before I asked this question.

Google can't suggest what product is good, and I want some recommendations from the users.

I tried several products but none solve my problems raised above, so I asked this question.

Thank you for your answer after all.
