Scored on 290 merchant reviews we hold for Fast Simon AI Search & Filters, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 290 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

I've worked with Fast Simon for years and it is very user friendly! They are constantly making improvements and updates to the apo, Our CS Manager and their dev team respond so quickly to any issues that arise.

Have utilized this app for two years now. Staff is friendly and quick to assist. Very nice app, however the metric used for billing is number of monthly users visiting your website. For smaller stores this should never become an issue, however as you grow - especially if you have a large number of pages or products in your store, the Google bots will utilize many of the visits. Out store has an average of nearly 10,000 bot visits per month due to our extremely large catalog, to which we keep adding products. This worked fine for us until we hit the top 10,000 visits/month at the $99 level, however as we have grown we now see an average of 25-30,000 visits per month. The next level package they offer increases from $99/month to $249/month - a 150% increase. After much research we found all of the other collection filter apps charge is based on the number of products in your store. We needed to switch to one of these apps, which work just as well.

very happy with the app and support, with a recent google core updates and a need for shopify to be fast was a challenging. Fast simon offering side rendering on collection page has speed up our score in page speed insight, we are very happy with the app

Developer repliedA pleasure hearing about the LCP and CLS improvement! Show more

An awesome app for search and collection management! The tools and information this app provides has helped our conversions and merchandising tremendously. The support team has been very helpful along every step of the process. If we ever need anything, we can always count on them to help us out!

Developer repliedGreatly appreciate the kind merchandising words! We love working with your guys at 707 Street :-) Show more

Excellent support, fast turnaround on requests. Easy to use with No Code Editor, Fast Simon is a complete Search & Disovery and product merchandising solution. Very little manual merchandising needed upon installation of Fast Simon- even for a store with a catalog of 30,000+ SKUs. Highly recommend.

Developer repliedA true pleasure working with you guys in Texas - true partners in the past year! Show more

We evaluated almost all search solutions and we decided to move of with Fast Simon. We increased search conversion rate, after improving UX with additional filtering options and machine learning. Great support, very involved during implementation phase and very fast answering any question via ticket.

Developer repliedTruly appreciate the opportunity to work together! Show more

Collections pages give slower scores on google speed insights compared to standard shopify collection pages. Fast Simon team says nothing they will do but just asks us to fix issues on our side. The response by Fast Simon team isn't accurate, the sales increase isn't 60%, it's around 30%. Luckily Shopify now has very similar features in the collections and search they offer plus it's free, i'll slowly move to it.

Developer repliedDear Fareed, Thank you for sharing your concerns, and we appreciate your business with theFredCo.com over the past two years. We understand the importance of website performance and its impact on your business. We want to express our gratitude for the significant role the Fast Simon platform has played, contributing to over 60% of your total revenues. Our goal is to continually enhance your store's conversion and SEO, and we take your feedback seriously. We acknowledge that certain themes and third-party scripts can affect performance. We have been proactive in offering guidance on these issues and even extended a complementary service to review the liquid in your store. However, we've encountered challenges in addressing the highlighted theme issues, partly due to the limitations in accessing the non-live theme. It's worth noting that your Google Page Speed Core Web Vitals Assessment for mobile is very close to being in the green zone. The Time To First Byte (TTFB) is the last piece that is still in the orange, and the suggested solutions we sent and wanted to review in the liquid are probably the culprit. As the Fast Simon team, we take pride in serving a diverse range of D2C brands, and we have not experienced such difficulties in cooperation with our clients before. We remain committed to finding a resolution that meets your expectations and improves your website's performance. We understand that the upcoming BFCM season is crucial for your business, and we sincerely wish you the best of luck. Our team is here to support you, and we remain open to further collaboration to address any outstanding concerns. Thank you for your understanding and continued partnership. Show more

Exceptional support and technical expertise. Whenever I have requested help, I receive prompt support and always a resolution - first time. Highly recommend!

Developer repliedThanks for your great review! Show more
