The Google bot is programmed to search for, and record, fresh content.
Every new concern/question posted here, and replies given, constitute fresh content. As a result, the bot visits daily.
Out of curiosity, I gave a voice command to my smartphone, which was "public mobile community". That was at about 4 am today, February 20. The first indexed result was a question and all its answers posted in the community yesterday, the 19th. That is how efficient Google is at indexing.
I wish to respectfully suggest the following to those members who respond to posts: Advise those members who post personal or otherwise confidential to return to their posts ASAP to either eliminate or obscure the information in question.
