Disagree.Google Analytics samples data. Thus... theoretically speaking it just doesn't absolute accuracy. Secondly... After recent also updates... ow that Google has stopped sharing keyword traffic data... it's become more tricky to quantify the actual number of visits. However there are ways to do it but tricky and advanced stuff. Having said the above... we will have to agree that GA is the most intuitive and user friendly analytics platform so despite its shortcomings I would go to Ga first before going to any other platform... any day.
