1. personalization – if personalization is on then the results you see might be different than the results other see. This is true even if you are not logged into keyword position checker an account results can be altered by your recent prior search queries. To remove personalization bias, we offer an option that turns it off.
  2. clustering – to send Google less queries we grab 100 results per page. If 2 pages from the same site are in the search results they will be clustered together, so in many cases a low ranking page will see rankings shown even lower on our tool due to clustering. If you add &num=100 to the address bar in Google the results should be fairly well aligned with our tool.
  3. datacenter and algorithm changes – at different times of day your query might access different datacenters, and also changes also happen all the time… Google did around 450 algorithm adjustments in 2007.

Even if the numbers do not exactly line up they are still good for helping you see the general ranking trends.

Yahoo! Search

In most major markets Yahoo! is currently in the process of transferring their search service to Bing. In markets where Yahoo! search is still powered by the core Yahoo! algorithm, our Yahoo! ranking numbers will be spot on because we use the Yahoo! API. However in markets where Yahoo! has shifted over you can use the other related ranking data.

  • In the United States, Australia, Mexico, Canada & Brazil Yahoo! Search is powered by Bing.
  • In Japan Yahoo! Search is powered by Google.

Once Yahoo! has fully transitioned their upgrade process globally we will upgrade rank checker to reflect their current results on a per market basis.
