Cons

"If you do not use JavaScript, you will be invisible to Google Analytics. If you have the option of JavaScript disabled in your browsers, you will be invisible to the data, since the tool will not be able to register you."
"Data capture of the acquisition of users, as on a few occasions, it was unclear where we got traffic from."
"They can improve their Android app."
"The sampling of data is definitely a pain point since we don't have an actual understanding of the data."
"It would be nice if Google Analytics provided all statistics, rather than a segment of the statistics."
"There is a time lag of 4 hours for the tracking to get updated in the system."
"Additionally, Google Analytics can be hard to pick up when you're just starting to use it."
"An area where I would like to see improvement in Google Analytics is the auto-syncing of functions in Google Tag Manager into Goal tracking."
"There were previously issues with experiments saving as expected in Classic."
"Verifying goals could be easier."
"Exporting statistics provide more statistical data."
"Does not allow multipage variants (i.e. allows only variants in elements inside one page)."
"When testing images or anything involving JavaScript or more than text, they can really slow down the load performance of a page."
"Better communication with 3rd party implementation"
 

Pricing and Cost Advice

"The installation cost is really low and does not require a team with a super performance to run."
