The SERP Tracker automatically updates all your keyword rankings once per week. The number of keywords you are allowed to track is dependent upon the number of search engines you are tracking keywords in. For example, if you track all your keywords in both Bing and Google, then you would be able to track a total of 500 keywords (assuming a limit of 1,000 keywords). If you track all your keywords in just Google, then you would be able to track a total of 1,000 keywords (assuming a limit of 1,000 keywords).

Feel free to select an updated date for any keyword to see the change in ranking from the date selected, compared to the prior update.
