If we talk briefly about the ‘Click to Chat’ feature of WhatsApp, this feature is known for allowing users to start a WhatsApp chat with another user without saving their phone numbers. The feature is used by websites to interact with visitors.

According to Jayaram’s comments, the phone numbers of the visitors who use this feature to connect to their websites can be displayed in Google Search results by adding them to a directory. Saying that the phone numbers appear as plain text in the URL, the error hunter says that 300,000 directories have been created on Google so far.
