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.

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.

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.

If a problem occurs while operating the site, fast simon will identify the problem in a short time and respond. I think anyone who has experience managing a site knows how important this is. So I recommend this app.

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.

Dear 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.

Fast Simon is crucial to our business. This app makes it so easy to set up our collection pages with the order of products we want. They're always updating to new and impressive tech. There are always new updates that push our site to the next level. Kylie, our rep, is the best. She always handles our issues very fast and lets us know when there is something better we can be doing to better utilize Fast Simon tech.
