Despite Google's extensive coverage, many website owners have trouble with indexing on Bing, where just a portion of their sites show up. In order to solve this, Bing provides IndexNow, a straightforward API that enables developers to submit updated or new URLs for indexation straight to the browser. You may increase search visibility and automate this procedure by using PHP cURL. Uncertain API answers, sluggish indexing, and trouble confirming submission success are typical issues, though.
