Using a fast and accurate internal search experience can really enhance user engagement, conversions, and overall satisfaction with your site. Those who search your site already know what they’re looking for; therefore, they expect to see instant and relevant results from those searches.
For many years website owners and developers used Microsoft Bing-powered tools to build custom search solutions on their sites. As web development has progressed, so has the need for deeper levels of customization, AI influence in regard to the relevancy of results, and seamless integration into existing business strategies. In this article we will compare Expertrec Site Search vs. Bing Custom Search so that you can determine which solution is the better fit for your site.
What Is Bing Custom Search?
Bing Custom Search is a Microsoft product that helps developers create a customized search engine based on Bing’s search results (index) for their website, set of domains, or vertical (e.g., product, category).
Bing Custom Search is typically implemented via an application program interface (API) or hosted user interface (UI) and utilizes Bing’s ranking algorithms to display results.
Some key features of Bing Custom Search include
- The ability to search a selected set of websites or domains
- API-based implementation
- Hosted UI options
- Control over ranking rules and blocked results
- Integration with Azure services.
Bing’s search engine can crawl billions of web pages and deliver super-enhanced search results (with images, news articles, and videos); however, mainly Bing Custom Search was designed as a developer tool, not as a complete on-site solution.
Important Update: Availability Concerns
Microsoft has announced that many developers will lose access to Bing search APIs, including Bing custom search APIs, when they retire from use.
These Bing APIs will no longer be available for new deployments or for functionality in existing deployments, leaving many businesses that rely on Bing for their search infrastructure to wonder what changes Bing search will bring.
