IndexNow Extension for OpenCart is created to manually or automatically send URL's to search engines (SE) that support the IndexNow protocol. At the moment, there are Bing, Naver, Seznam.cz, but it is expected that soon other search engines will be connected to this protocol.

IndexNow is a new protocol for interacting with search robots, it allows you to inform search engines about new pages or content updates on already indexed pages. That is, this is a new way to instantly notify search engines about new or changed content on the site, which will lead to quick indexing of URLs and their appearance in the search results. You do not have to wait several days or weeks for search robots to find changes on the site and index them. Having received links through the IndexNow API, search engines prioritize them, thus limiting the crawling of robots to discover and receive new content.

To start working with the IndexNow protocol for your site, you will need to create a special key and place it in the site folder on the server to verify the rights to the host. But with our module, all this is done automatically with one click of the "Generate" button, it will create a key file and write it to the server. Our OpenCart plugin sends POST JSON requests to the SE handler containing the URLs that need to be indexed. Search engines that use the IndexNow protocol immediately report the received links to all other search engines that work with the IndexNow API. That is, by sending a request to Bing, other SE will automatically receive your link, and vice versa.

The IndexNow OpenCart SEO module can automatically send links for indexing during the following operations:

Adding a new product
