And especially, 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 way to make the catalog search easier and more flexible because people can use different words to describe a 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 the customers search your product and lead them to the relevent page.
