What is pinging?
Pinging is a process used to confirm a connection between two devices. One device sends a ping request to another and it should successfully receive a reply. If this happens, it means the devices are connected and can transmit data between them.
When it comes to SEO, pinging is used for updating the search engine about changes on a website. The pinging services ensure that this is done automatically. Using this method helps with having a web page indexed more often.
