Search insights have reduced no-result queries and guide visitors quickly to relevant content
In my opinion, the best features Coveo offers are that it's quick, it's easy to navigate, and if you have something you want to know, Coveo is very helpful in helping you find out how to get the information that you need and sort the information that you need. Of those features, the main thing I find myself appreciating the most in my day-to-day work is being able to find what I need without spending a huge amount of time. The speed and easy navigation are important; there are other tools that do the same thing, but finding what I need quickly really matters.

Robust solution with good value
Microsoft FAST is quite robust. Our clients are quite happy with it. For other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components. If you are with any other third party, there could be a chance that the required output is not what you would expect. But with Microsoft, it will work better. It is compatible with the older generation systems, so you can offer it. On a scale of one to ten, I would give Microsoft FAST an eight because I'm quite comfortable with it.

Quotes from Members

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

Pros

"Coveo provides AI-driven search results and proper recommendations based on customer interaction and context, which is very beneficial for us because it improves our order conversion rate, allowing customers to find the exact products they want and see similar products, greatly increasing upselling."
"One of the standout features of Coveo is its AI-powered search relevance, which helps users find the right content quickly."
"Coveo already has a very good e-learning platform with multiple courses to learn and certifications to achieve, so it is very good in terms of the learning curve for new users or developers working with it."
"After migrating to Coveo, it took less than 10 milliseconds to load all this data."
"Coveo has positively impacted my organization by cutting down the number of no result searches from something like 15% to about 5%, which is huge, saving calls to call center people and probably preventing people from seeking out products from our competitors, so we get people to pages that they want more quickly and more effectively."
"AI-enabled query suggestions help users return more frequently and build trust in the search capabilities our site offers, allowing us to drive content towards users based on popular queries."
"In terms of accuracy and reliability of output, I believe Coveo is probably the best in market scenarios."
"Before moving to Coveo, we had metrics of user clicks around two million, but after we went live with Coveo, user clicks and all view analytics jumped up over 3.5 million, which was a significant upgrade after implementing Coveo."
"Microsoft FAST is quite robust, our clients are quite happy with it, and for other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components."
"Microsoft FAST is a really amazing search application."
"Microsoft FAST is quite robust. Our clients are quite happy with it."
 

Cons

"Coveo can improve by supporting a few more languages."
"One area of improvement for Coveo is the size limitation concerning response results."
"I chose eight out of ten because we have some limitations, such as when we share heavy data, where a large number of data takes more time for Coveo to process; that is one area where Coveo needs to improve, but apart from that, it is good."
"I faced some challenges regarding the accuracy of the search results with Coveo."
"The main area I would improve is the learning curve because there are many concepts and configuration options, and understanding how indexing, query pipelines, security, and all those pieces work together requires experience."
"I would give Coveo a nine out of ten because the response and everything is fine, but the technical team of Coveo helps us, yet I think it is not one hundred percent."
"I think the pricing was definitely on the higher side, and the professional services were also quite costly."
"In a general sense, we are not seeing a remarkable return on investment because maintaining Coveo for our search functionality is costly, and we have to balance investments in search versus other areas."
"We do get support from Microsoft, but the response is quite slow."
"If there is any change in a system or a configuration or an update, we might face some issues."
