Why Internal Search Drives Your Conversion
People with a specific purpose type into the search bar. This purpose often leads to larger shopping carts and shorter search paths. A good search function delivers relevant results, is error-tolerant, and offers clear filters. This allows users to quickly find the right product.
The search function provides you with data. You can see what buyers are searching for, which synonyms they use, and where there are gaps in your product range. This data helps with product range, content , and SEO.
