Google has always tried to maintain the reputation of its web site analytics software to be trustworthy for its users. The online analytics tool by Google has alway to preserve the privacy of its users along with making the tool more transparent for both website users and site owners.
This has created heated response from users all over the world and many have raised serious concern over this. Many fears that they will see a drop in the traffic numbers as per the Google web site analytics tool as Google Analytics would not be able to track the traffic details coming from browsers which has Google Analytics Opt-out Browser Add-on enabled. This add-on will surely make difficulties in generating accurate website traffic reports as they would not have any clue on the missing data.
This is certainly going to create issues to Internet marketing professionals such as SEOs, SMOs, SEMs, Web analytics professionals etc, who consider Google Analytics as their major source of online analytics. This might also prompt a few of them to turn to another website analytics software, but they might find it difficult to find a free tool as effective as Google Analytics.
In my opinion this Add-on will create some serious issues for those who are serious about their analytics stats and are in search of accurate data rather than relative data.
