In today’s blog, I examine how 5 prestigious Shopify eCommerce stores set up their Shopify filter and search. I also consult with our experts to give you the top secrets for online store search engine optimization. But first, let’s see how it works by default.

An overview Shopify Filter & Search

Shopify Search & Site Search Results

The default site search engine of Shopify gives merchants some useful functionalities like:

  • including both singular and plural search terms
  • automatically using “AND” to connect searched keywords
  • ignoring misspelling up to 2 letters

However, the search range is limited to Product, Article, and Page fields. Typo tolerance only works when you have the first 4 letters in the correct order. Also, Shopify search lacks useful features to reduce searching time like the prompt suggestion, auto-correction, fallback search that only Shopify custom search (or Shopify search app) offers.

To help you create an enjoyable shopping journey in 2022, we have revealed untold secrets of leading brands' success - how they better the search bar and navigation to skyrocket sales. What's more, it's FREE.


Product Filters in Shopify

By default, Shopify merchants have only one option for Shopify product filter, which is filter by tag. To add insult to injury, no product filter automatically appears on the search result page. If you want to add one and facilitate your customer experience, you will need to deal with a bunch of code. Such technical pain!

So, will you let the standard yet hazardous site search and product filter of Shopify lure your potential customers away?

No, you never should do it. An investigation of 21 cyberspace stores conducted suggested that web visitors who do a search accounted for 13.8% of the online sales. That said, there is a lot of room for your store bloom by upgrading your Shopify filter and site search.

To help online shoppers navigate the right products, ColourPop implements a distinct top filter for each collection and sub-collection. Still, some filter options are available for all, like “Shade”. You know how important it is to pick the right shade when it comes to beauty products. So, ColourPop initiates a swatch in their Shopify filters as a color picker for makeup addicts to find what they need.

Spell-check and auto-correction

Typos are common when customers search for a product. The downside is that the results may not show when a spelling error occurs. It is frustrating to customers and they may leave your site right away even though it’s not your fault.

ColourPop eliminates this issue by a robust spell-check and auto-correction. As you can see in the picture above, Colourpop’s site search doesn’t crawl the misspelled words. Consequently, the result page doesn’t turn out blank. The company does one thing more to facilitate purchasing decisions with the “add to cart” button in the product listing. It’s a great practice to prompt searchers to actually buy the product they search for.

Lessons learned from Top Shopify Site Search & Product Filter

For your Shopify filter menu

  • Try both layout product filters: horizontal and vertical

Experts’ advice: The left sidebar position is suitable for a large number of filters (more than 8), which will grow over the period of time. If you have around 3-4 filters that stay pretty the same all the time, the top filter brings a better layout. In case you have a multitude of Shopify filter options, try the 2 layout filters as GAP does. Make sure they don’t overlap.

  • Customize filter for each collection

Experts’ advice: Because customization can take a great deal of time and effort, we suggest a default Shopify filter with the shared options and add more specific variants to a certain collection. However, don’t go for more than 10 displayed filters. The complexity of categories leads to confusion rather than helping users navigate the right products.

  • Optimize for a mobile experience

Experts’ advice: The best practice for a mobile-friendly filter is to use a collapsible sidebar or top bar. Also, allow your customers to show or hide filter values so that the Shopify filter tree is not too lengthy.

For your Shopify faceted search

  • Play it safe with the search box position

Experts’ advice: Most of the eCommerce sites place a search box on the right side corner with a magnifying-glass icon to signify the search. In this case, it’s helpful to follow the tradition because our customers are accustomed to the right side search box.

  • Work with the search box design

Experts’ advice: You can make it more noticeable by adding a different color or some text to the box. Instead of common sentences like “Search here”, “Search”, let’s be a little wind. A good example is “Find your new items”, “Explore your closet”. The search box text can also work as a guideline with words like “Enter product, code, or brand”.

For your site search functionalities

Experts’ advice: In the worst case, when customers search for a non-exist product on your site, it shouldn’t return a blank page. The best practice is to show other product recommendations after saying something like “We couldn’t find what you search for, but we have some suggestions”. It would be a much better user-friendly experience than showing a blank page. Also, make it another opportunity to present your products.

  • Advanced features: Analytics, Stop Words, Synonyms, Merchandising...

Experts’ advice: Based on the data in the site search analytics, you can create Stop words to eliminate redundant parts of a search term or better the Synonyms usage to show customers more relevant results.

In the time of AI technology, we are expecting a lot more changes in site search functionalities. Voice search might be used in an internal search. Deeper personalization in terms of gender, preference when suggesting products might come in the near future.

  • Third-party app integration

Experts’ advice: The best apps to integrate into the product listing are review and wishlist. In fact, 88% of consumers believe in online rating while WishlistKing and Smart Wishlist enable visitors to save the products for later purchase.
