Quotes from Members

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

Pros

"The speed index has had a great impact; earlier we had something in the 60s on Google Page Insights, but now we are able to achieve 90-plus."

"Contentstack is a great tool; the service helped us stay on track with our headless launch and deliver on time, and we are beyond happy with the service provided and still being provided."

"Contentstack has impacted my organization positively by helping us to deliver an application with a very good quality in terms of how it looks and feels."

"Contentstack has created an impact of quick access to a non-tech person to add the properties right away and to work on their own personalized marketing campaigns and other aspects."

"Contentstack has positively impacted our organization, as tracking changes made by our very large team is difficult, so we are using Contentstack to update data in real-time."

"The ease of use, which I mentioned as the best part, is especially highlighted by the clean UI and predictable UX of Contentstack, as there is not too much information on the screen at the same time that can confuse the users."

"Contentstack has saved time and improved efficiency, and compared to other products, it is cost-effective and not expensive."

"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."

"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 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

"For improvement, I want to clear the cache for the pages, as Contentstack does not provide a default way of invalidating the cache."

"The API, specifically the Content Delivery API, can be a bit tricky sometimes."

"Contentstack is much more complex and advanced technology. I think there are still some UI improvements which can be done to simplify the work."

"We are more worried about the pricing. For example, somebody who is a tech person trying to integrate based on the events finds it a little bit more not so accessible."

"It is good, but not great. For something like eighty percent of my set of tasks, I can scale based on the background we have with Contentstack."

"I noticed that sometimes it takes time, and I am not sure about the server side, as it may not be responding."

"Exporting statistics provide more statistical data."

"Better communication with 3rd party implementation"

"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."

"Does not allow multipage variants (i.e. allows only variants in elements inside one page)."
