Analytics discrepancies

[dawsonski]

Hi Guys

There appears to be a  discrepancy between our website’s  on site analytics  and google anayltics.  For  the period from the 16th of April 2012 April to the 16th  of May  2012 ,our onsite anaytics shows a total of 5036 visitors, whereas Google is showing a slightly lower amount at 4759 visitors. Both figures include unique and returning visitors. Does any body have any ideas as to why there maybe a discrepancy?

every analytics program uses its own method of evaluating real vs. bot based visits.  Further, Google even states GA is not based on complete data but instead, is a snapshot. Which is their way of saying "we know our data methods may be flawed, like if someone doesn't have JavaScript enabled, we can't count them, but instead of just saying that, we give this fancy disclaimer buried away so most people will assume it's complete and accurate".
