Why are search filters important?

A good set of filters and facets also ensures an improved user experience. By helping users drill down to their needs with ease, it eliminates the need for numerous searches queries just to find something specific. This improves brand loyalty and customer retention.

Should filters be on left or right?

4. Filter bars better showcase filters. By making the filters more prominent on the page and by making them available as the user scrolls a filter bar does a better job of showcasing filters. Presenting filters left to right also makes it very easy for users to quickly see what options are available.
