A programmable search engine is a tool to include a search engine on the website to provide users with high-quality and relevant search results. There are options to customize the website’s look and feel along with the features like refined search, promotions, and auto-complete.

A personalized search is when a search engine customizes the results based on a user’s location, search history and known preferences. Integrating personalized searching will reduce bounce rate and increase conversion rate. A few aspects of personalized searching include accounting for user location, native language, writing and purchase history.
