Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Tracking of the website visitors and web page analysis became an easy task."
"We have increased our visits, views, and average stay on site time, which has led to an increase in revenues, and better targeting of our digital marketing campaigns."
"In my opinion, Google Analytics fulfills the role it plays in a good way."
"Every online business needs to know where traffic is coming from and what it does when it gets to you."
"The User Explorer is a definite favorite because it allows us to pinpoint a user and check their entire journey through our website including all the events triggered and the pages visited."
"As an SEO and digital marketing professional, the two features I have found the most valuable about Google Analytics are the Acquisition tracking and the Goal tracking."
"Once you get the hang of GA, you can really use it to your advantage."
"Even though it's free, Google Analytics is packed with many of the same reports you'll find in high-priced solutions, especially concerning data relating to real-time visitor tracking."
"ROI: Infinite! (Got 3X conversion improvement using suggestions given by the product during the free evaluation period)"
"Customer service is wonderful."
"Optimizely can work for a lot more things than only testing; it is a pretty easy yet powerful tool."
"Dead simple A/B testing with no code knoweldge needed."
"Customer service is the best in the testing industry; transparent support along with a very strong community."
"Optimizely is a great product that has inspired a great community and is the standard for A/B testing."
"Customer service is excellent!"
 

Cons

"The technical support from Google has room for improvement."
"Beginner users access the live help section a lot, because of how confusing it is, so it would not be bad if the function was located within the administration section."
"The sampling of data is definitely a pain point since we don't have an actual understanding of the data."
"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."
"While it provides a lot of data, the data is not always accurate. So data accuracy could definitely be improved."
"Some spam data is messing up the analytics report; Google should remove spam data."
"Additionally, Google Analytics can be hard to pick up when you're just starting to use it."
"Sometimes, the statistics are not updated in real-time and it takes a little time. There are pages where it updates faster than others."
"Does not allow multipage variants (i.e. allows only variants in elements inside one page)."
"Better communication with 3rd party implementation"
"Exporting statistics provide more statistical data."
"When testing images or anything involving JavaScript or more than text, they can really slow down the load performance of a page."
"Verifying goals could be easier."
"There were previously issues with experiments saving as expected in Classic."
 

Pricing and Cost Advice

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