Search Terms is configured by admins on Magento 2 stores, that means customers need to type the keywords of the needed products and get them on the search results. And interestingly, you can make an small survey of the customer demands via the search terms by tracking what the clients are looking for on your store. When the number of searches for an unvavailable product are enough large, it is time to add it to your catalog. However, at this time, if the customers leave without any item, you can adjust the following ways:
With the landing pages, you can use a content page, category page, a product detail page or a page on a different site for the search.
The synonyms are one of the best ways to make the catalog search easier and more flexible because people can use different words to describe an item they are finding. For example, allow entering the synomnyms of “computer” such as “PC”, “Tablet”, “Mobile”, etc.
This way helps you detect the common misspelling when customers search for your products and lead them to a relevent page.
Today, this tutorial will describe the way to configure the Popular Search Terms easily, and you can also get the guides about the adding search terms and search term report when coming to the next topics.
Enabling the search term links in the footer of your product page allows your vistors access to their interests quickly, simultaneously, see possibly the popular search terms used by other customers. The popular search terms are considered as a search engine optimization tool without connecting directly to the catalog search process because the search terms page is indexed by seach engines, and any terms on the page can help make your search engine ranking higher and the visibility of your store.
