One of our services is that where user log on into his Dashboard and enter keywords that he wants to track.Then, we check for top 10 URL-s for every keyword you entered, and we do that on every 6 hours.
After few days of testing, we are now ready to give you reports for all your keywords.
So, if you log in, and go to your Dashboard and click to Reports tab you will see something like this:

And further more, if you click “User Keywords with Trend change Only” link (marked with yellow arrow on image above) you will narrow results to those where trend is changed since last update.

In this example we see that page with URL http://keywordremix.com/keywords/ is up by 1, that means that 6 hours ago he was on position 5, and now he is 4. on Google.
In this particular example, we can easily conclude that page which is now on position 7 was on position 3 on previous update. Since then he dropped 4 places, and because of that 4 other pages moved up by 1.
In next few days, after we are sure that everything works fine we will start to give our users tools to export this data to Excel and/or CSV and many other nice tools.
