I will not be supplying my telephone number to any search engine authority and that, because I do not wish to be spammed through my cell phone, and that because I no longer trust Google since they backtracked on their principles.
I NEVER, in ten years of service, got an unsolicited text or unwanted text on my phone -- until I registered my phone with google. I am SOO mad that I did that. Now I get at least 2-3 spam texts a week, PLUS Google themselves keep calling me wanting to sell me advertising! I keep telling them that I don't need to take out ads because if you are looking for belly dance classes or a belly dancer in my town, no matter how you word it, my site still comes up first.
I'm waiting for the day when google makes you pay to be listed in their search engine, just like the yellowpages. The era of the useful and free internet is almost over.
