You can establish and monitor your real name's Google presence, but you won't get complete control, especially when others with your name try the same tactic. Using a pseudonym/alias/author's name in conjunction with pages you control can be much more effective.
Mister Jalopy, a true DIY enthusiast, writer and all-around device enthusiast, takes his nom de plume to the extreme, preferring not to give his real name, even in interviews. You wouldn't have to do the same to get the same benefit he does from the "Mister Jalopy" tag, though — just use a unique alias in conjunction with sites and profiles you have the most say in:
If you Google my nom de bullshit, Mister Jalopy, all the top hits are for web pages that I control. And my e-mail address is right on the front page of all of them. For detractors, fans and spam scraping robots alike, I am super easy to find.
Mister Jalopy utilises all the methods Jason detailed in his online identity how-to, just with his alter ego instead of his real name. It's worth considering, especially if you're one of the world's Robert Smiths or Nancy Jones.
