Can anybody share their experiences about google analytics based on its accuracy? I am having doubts because my blog regularly gets 3000+(3000+ impressions) credit points from 1800banners but in google analytics, it only registers 30-50 impressions with an average bounce rate of 40-60%. There is a big discrepancies their. Another interesting fact I observed is that I am getting lots of visitors from entrecard about 20/day but only 3 is registering in google analytics.
