Why 1 keyword has different stats in 2 reports:


- Because of the "report creation time".


- When you search on Google, the SERP result depends on many factors (your search intent, the history of your searches, Google cache, etc.) so the All-in-title and SERPs result at two different times are different (we also utilize All-in-title in our Golden Filter - updated KGR).


Example about All-in-title:


- At 9:00, the Allintitle result for "What is the best dog food in Walmart" has 5 posts about it, so the Allintitle score is 5, and the SERP results have 5 sites.


- At 9:01, Walmart.com has published one more post on that keyword, so the All-in-title score is now 6, and the SERPs result has 6 sites. 


Example about SERPs:


+ At 9:00, The first ten sites on SERPs are ( A - B - C - D - E - F - G - H - I - J ) and the 11th site is K

+ At 9:01, The "K" receives some things that make google think K is better than J, so the SERPs now is ( A - B - C - D - E - F - G - H - I - K )


Some tools in the market right now cache your keyword data a few days ( or a few weeks) to optimize the loading speed. WriterZen doesn't do that, every single query, we will get the latest data we could to maximize the accuracy.


Here is the video that shows there is a difference between two searches (same keyword) in just a few seconds. In the first search, All-in-title is 21 and in the second search, All-in-title is 155. 

So the best way we could do is to simulate the search query and show what Google gives back to us.
