## An introduction to IndexNow and why you should care

2/1/2022 - Web

IndexNow is still relatively new but is getting a lot of interest in the search engine community. Hopefully, you can soon submit your content once to IndexNow, and stop manually submitting those URLs to every search engine console manually. And instead of search engines having to crawl the web over and over to look for new content, the content can be delivered directly from the source, reducing the environmental impact of crawlers.
