- personalization – if personalization is turned on, the results you see may be different than the results others see. This is true even if you are not logged into an account, the results may be altered by your recent previous search queries. To eliminate personalization bias, we offer an option that turns it off.
- grouping – To send fewer queries to Google, we get 100 results per page. If 2 pages from the same site are in the search results, they will be grouped together, so in many cases a low ranking page will see even lower rankings in our tool due to the grouping. If you add &num=100 to the address bar in Google, the results should align pretty well with our tool.
- data center and algorithm changes: At different times of the day, your query may access different data centers, and changes happen all the time too… Google made about 450 algorithm tweaks in 2007.
Even if the numbers don’t line up exactly, they’re still good at helping you see overall ranking trends.
