Constructor Reviews & Product Details

We really appreciate the AI- and data-driven approach of Constructor. The system is pretty easy to use both for technical and non-technical people, integrates nicely with our IT landscape and helped us to significantly improve our search performance. It quickly became essential for our customer experience and there is an ever growing list of continuous optimizations for the upcoming months. It is great fun to plan, see and measure the impact of Constructor initiatives. On top of that, their customer support is top notch and it really feels like a strategic partnership where both parties benefit from each other. We really look forward for the next steps.

The explainability of the search results is working pretty well already, but can be improved even more in the future, e.g. by showcasing the underyling rules causing certain boosts. Furthermore, being able to run more fine-granular A/B tests on search query level would be awesome. Review collected by and hosted on G2.com.

I appreciate having a great sparring partner, Niklas Broeker, who helps us out and is always available for questions and suggestions. I like the feel and look of the Constructor page itself, and it really helps that we have documentation and actual people we can talk to, which is the most important point for us. I don't remember what's it called, but Constructor offers more than just software; there's also the 'knowledge' and help behind it, which so far has been the best value for our team. Also, the initial setup was easier than I thought, easy enough. Review collected by and hosted on G2.com.

I do think that though I love the feel and look of Constructor's page, it could be more intuitive. I feel from an intuitivity standpoint, it's hard to navigate the tool. Also, there is much documentation, nevertheless not really 'on point,' you really have to dig sometimes. Sure, for example when we click on an item; I want to be able to instantly check why this item is ranked this way and why. I get that as a software service you cannot be 100% transparent about your algorithms, though sometimes it's hard to understand certain aspects, like which boost rule pushes this item up to 5%, etc. Review collected by and hosted on G2.com.

There may be a few opportunities for further refinement. In some cases, the algorithm appears to take a bit longer to adapt, which can temporarily affect the relevance or completeness of the results. There also seems to be room for improvement in how transliteration between English and Greek is handled. Additionally, it would be greatly appreciated if rule changes could be applied instantly, as immediate visibility of updates would be very helpful from a usability perspective.

We like how Constructor's search provides better contextual matching to user queries and offers improved ranking of products. We appreciate the advanced machine-learning click-stream analysis, which allows us to optimize the entire site in near real-time. The fact that our A/B tests show Constructor's choices outperform business rule overrides gives us confidence in the system. We also find the simplified interface and the overall machine control approach with click-stream and personalized ranking to be a big improvement over our previous solution.

Our fast-track implementation did not allow us to utilize the full features of the app, such as fine-tuning facet controls through the dashboard or leveraging features like their collections. Initially, the product recommendations were very poor and this did require more business rules to get it working as we wished. There are several A/B features we wish added, such as sessions, revenue, and orders and the ability to break A/B metrics down by device. Review collected by and hosted on G2.com.

The biggest win for us has been the commercial impact, especially through Recommendations - the revenue lift has been outstanding. We’ve also seen strong results through independent A/B testing, including improvements from recommendation engines and geo-localised ranking, and we’ve almost eliminated zero search results, which has clearly improved the customer experience.

Just as importantly, Constructor feels like a genuine partnership rather than a vendor relationship. The team is highly responsive and easy to work with, always available on Slack, and quick to pull in the right people when needed . That combination of measurable performance impact and a strong working relationship has made a real difference for us. Review collected by and hosted on G2.com.

Constructor is premium-priced, and while the ROI is clear from our results, the cost means we still have to regularly re-justify it internally

Early in the implementation, Constructor could have had a better understanding of what makes our business unique so they could give us better advice from the outset. That said, we did ultimately get the help we needed, and the team has been highly responsive throughout.

One area that could be improved is visibility into catalogue updates. It’s not always easy to see when and how products have changed, which makes it harder to validate our integration. Review collected by and hosted on G2.com.

Constructor stands out for its powerful search and browse capabilities combined with a high level of configurability. We use search, browse, and quizzes extensively, and they help us deliver relevant, guided product discovery while maintaining full control over merchandising decisions.

Occasionally, some features take a bit of time to be fully rolled out, but the team is always open to feedback and receptive to our input, which makes the process feel collaborative. Review collected by and hosted on G2.com.

The design and the browsing environment, which is intuitive and easy to navigate. Additionally, we receive prompt responses whenever we need assistance or support. Review collected by and hosted on G2.com.

There are a few minor points regarding date selection, as the option to choose a custom date range is not consistently available across all sections. Also, It would be helpful if data exports were available in a ready-to-use format, so they can be downloaded and used directly without requiring additional processing on our side.

The javascript API works perfectly, it is easy to configure, understand and use.

Also the way beacon works connecting all properties needed in HTML it is great! Review collected by and hosted on G2.com.

One point it could have improvements is the way object fields works as facets.

for example if I have different prices for different countries and I store this in a price object with the country code being the key, I would expect to send a facet like `price.US`, but we need to send just `US` and this could conflict with other metadata.

The features and their willing to help or to extend their products. Review collected by and hosted on G2.com.

First level of Customer Support is poor. After escalation the problems were solved. Sometimes we are running on performance issues. Review collected by and hosted on G2.com.

Constructor excels at delivering personalized search results based on our user activity. It understands customer's intent rather than just terms, substantially simplifying our customers' product discovery process. I particularly like how the real-time merchandising controls allow us to highlight essential products or campaigns without the need for developer support. Review collected by and hosted on G2.com.

I sometimes feels like driving a high-performance car without a clear map incredibly powerful, but not always easy to navigate at first. A more guided, user-friendly interface would make the experience smoother for me. Review collected by and hosted on G2.com.
