Delays beetwen serp checkers ?

Hello

I have 3 serp checkers and all 3 have different results.. Free pro rank tracker, Free serplab and paid serpbook.. So in the both free pro rank tracker and free serplab I'm ranking on google for keywords but in serpbook is not showing that I'm ranking for that keyword ?

Might be google dance.

Might be many reasons...not all rank checkers are instant or live ranking checkers..once in a day or once in some hours it will update the ranking so you have to check the settings in each checker n project settings and check the Geo location of the rank checkers..I personally use paid serplab so it will update 24 hours as per the default settings.

Ok thank you will check

Google has something like 200 data centers that they pull results from, so the different serp checkers could be using different data centers. There's also the 'localization' thing. If one person in one city enters a keyword, and a different person in a different city enters that same keyword, the two people will see different results based on their locations. I don't think it's possible to ever get one, true, 'real' result for any one keyword. That might be part of the issue.
