When I first opened my Shopify store, I thought the hardest part would be finding products or designing pages. It turns out, one of the things that had the biggest impact on sales and user experience was how customers search for products.At first, I relied on Shopify’s default keyword search. It worked… sometimes. But I quickly noticed customers often typed natural phrases that didn’t match my product titles. For example, someone searching for “gifts for teens” wouldn’t see my “Teen Accessories Box,” even though it was exactly what they wanted.That’s when I discovered semantic search, and it changed how my store handled search queries completely. Here’s how I did it, step by step, and what I learned along the way.

Step 1: Install Shopify’s Search & Discovery App

The first step was installing the Search & Discovery app from Shopify. I realized that Shopify’s default search doesn’t fully understand natural language. The app gives you more control and, importantly, access to semantic search.Once installed, you can access settings for search relevance, synonyms, and product boosting. This was the foundation that allowed my store to interpret what customers actually meant instead of just matching exact keywords.

Inside the app, there’s an option for semantic search. I enabled it and noticed immediate differences. Customers could type longer, natural phrases like:

  • “Comfortable running shoes for summer”
  • “Eco-friendly gifts for office”

…and my relevant products started appearing even if the titles didn’t contain all the exact words.This was a big win because it reduced the frustration of “no results found” and increased engagement.

Step 3: Add Synonyms and Custom Rules

After enabling semantic search, I spent some time adding synonyms. For example, I grouped:

  • “Sneakers” and “trainers”
  • “Sweater” and “jumper”

I also created some custom rules for products I wanted to promote during sales.This step is important because even semantic search isn’t perfect. It benefits a lot from guidance to understand your specific catalog and the way your customers speak.

Step 4: Improve Product Titles and Descriptions

I quickly realized that semantic search works best when your product information is rich and descriptive. I started writing titles and descriptions that:

  • Used natural language
  • Explained what the product is for
  • Included key attributes like color, size, and material

For example, instead of “Red Jacket XL,” I changed it to “Red Waterproof Jacket for Winter Hiking – XL.” Not only did it read better, but it also improved search relevancy.

Step 5: Monitor and Refine

After a few weeks, I checked which search queries were returning poor results. I adjusted synonyms, boosted certain products, and updated descriptions.It’s an ongoing process. Semantic search gives you a strong foundation, but monitoring actual customer behavior ensures your search keeps improving.

What I Learned

  • Customers type naturally. They won’t always use the exact product names.
  • Semantic search reduces friction. Fewer “no results found” moments lead to higher conversion.
  • Good product metadata is key. Titles and descriptions matter more than ever.
  • Synonyms and rules help. Tailoring search to your catalog makes it smarter.

Since implementing semantic search, I’ve noticed more products discovered organically through search, and customers spend less time hunting. It may seem technical, but the results are worth the effort.If you haven’t experimented with semantic search yet, I’d suggest starting with the Search & Discovery app, enabling semantic search, and gradually refining your product information. It’s a small change with a surprisingly big impact on the shopping experience.
