31 Detecting an inserted code

Now, coming back to the issue of inserted codes doing various kinds of tricks and broadcasting signals, there is this minor instance that can be mentioned. There is a way that Google asks a web owner to verify his or her ownership of his or her website. A very small code is given as a Notepad file. All the owner has to do is to upload it to his or her server. And inform Google that it has been uploaded.

Now, this informing is not calling Google or sending Google an email. Simply click on a button that says Verify or something like, Uploading Over etc.

Within seconds, Google crawler will visit the uploaded page, and receive the information that it is on the server. It is something like, the notepad file giving a shake-hand and saying, Oh, Yes, I am here. He/She is the correct owner.

It is as simple as that. Or as complex as that.

It is simple to the extent that this work is quite easy. It is quite complex due to the fact that one should know how to write the codes, and to create a crawler to go and give the hand-shake.
