Empowers teams to build visualization-rich reports and make faster decisions using historical user behavior data
I think areas for Amplitude's improvement include data retention. The maximum data I have worked with, the clickstream data on Amplitude, is two years, whereas we rely on Tableau for historical data of at least two years. I am not sure whether it was my organization paying for lower retention or not, but having historical data would take away the reliance on Tableau. Secondly, reconciling clickstream data with Databricks or other AWS systems could help analysts spend less time verifying the accuracy of both sources, which would be really helpful. Lastly, a more focused approach on error logs is necessary. I have found that, at least with Intuit, we used Splunk more for error logs than Amplitude. Although Amplitude had the capability, developers seemed to prefer Splunk, so if that could be improved, it would be good.

Quotes from Members

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

Pros

"Amplitude has provided almost instant value to our dev team when they are deploying new trackable events and seeing how those events line up before they go out to production."
"Amplitude impacts my organization positively as it serves as a central point that allows everyone within the organization to speak the same language of data."
"Amplitude has provided a return on investment, helping us improve campaign targeting and raising personalization accuracy by almost twenty-five percent, while saving us a lot of time since I can see the analysis as quickly as possible in the dashboard, resulting in significant time and money saved."
"Amplitude is a perfect product that will always fulfill all the data-related needs that your company has, and I would suggest anyone to go for it."
"I loved using Amplitude because it allowed me to dive deep into product usage and analyze different customer segments."
"Having accessible data which can be easily customized and manipulated by even business stakeholders with less technical knowledge is one of the best things."
"We can create charts and bar charts for visualization purposes and check real-time data with the solution."
"Amplitude offers flexibility in real-time data analysis, allowing users to make immediate decisions."
"Optimizely can work for a lot more things than only testing; it is a pretty easy yet powerful tool."
"Customer service is wonderful."
"Customer service is excellent!"
"Optimizely is a great product that has inspired a great community and is the standard for A/B testing."
"ROI: Infinite! (Got 3X conversion improvement using suggestions given by the product during the free evaluation period)"
"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."
 

Cons

"I choose nine because, lately, when I was using it, the more people wanted to improve, the more complex things got—not in a good way, but confusing."
"Amplitude is almost perfect, but there are some charts I cannot create due to the large data structure."
"We have seen tagging issues with Amplitude in rare scenarios, which can be improved."
"We attempted to use their screen recording and session recording capabilities as a replacement for a previous vendor, and we found that the functionality they offered did not stack up to the previous vendor."
"I give it a nine because it is close to a perfect ten for me, but it is only useful in one layer of the project, not the other, which the tool is supposed to do."
"Regarding how Amplitude can be improved, I think that dashboards and charts are ephemeral; people often create dashboards but rarely revisit them, so while a handful of dashboards might survive, the real value lies in the insight derived from them."
"The visualization of the properties can also be enhanced. Basically, the visualization could be better, and the real-time analytics can be enhanced."
"Setting up reports in Amplitude was challenging for me as a newer user."
"When testing images or anything involving JavaScript or more than text, they can really slow down the load performance of a page."
"Exporting statistics provide more statistical data."
"Verifying goals could be easier."
"Does not allow multipage variants (i.e. allows only variants in elements inside one page)."
"There were previously issues with experiments saving as expected in Classic."
"Better communication with 3rd party implementation"
 

Pricing and Cost Advice
