Allintile query showing different results than Google

Hi there, I am trying to get the allintitle number of results for a given set of keywords.
Unfortunately I am experiencing the following problems:

  • List item Number of results is different between what I got from SEOTools and a real search on Google.it

  • List item Sometime I got a #NULL results

the sintax I am using is the following: Connector("GoogleSearch.NumberOfResults";Sheet1!B2;"intitle:";;"all";;;"google.it")

Can you help me please?
