Drock101 is right. This does work and it is completely safe if "done right". Amazon Turk or bots will not work.. It has to be real people (thousands) which is why this is extremely hard for SEO companies or people like you and me to implement themselves. For example lets say Brad Pitt (I have no idea why that came to mind BTW) went out to his Twitter acct. and said Hey guys, I need you to do me a favor, go to Google and do a search for Orange County Plumber + [Business Name] and thousands of people went out and made this search. There would be a buzz right... Real people searching for a location + keyword + Business name. (exactly what Google wants). Now lets say this happened over and over again throughout the course of 30-90 days. Its real people searching for something and before too long, your new long tail keyword will start competing with Orange County Plumber because there is way more buzz surrounding it and that is exactly what it wants to suggest to its searchers. If Google sees that kind of search volume from real people they can only assume that it is very popular and should be suggested.
I am actually using this myself right now to rank for keywords in my business. I have seen it personally work and those who are using it around me are getting a ton of new leads on a monthly basis.
So let me ask you... If Google finds out, which they do already know about it by the way... How can they came after you? If it is real people searching for a keyword and your business name... There is absolutely no tie in to your site whatsoever. The results would pull up everything about you (Your website, Yelp, Facebook, Linkedin, Articles written etc.) So how would your actual business be penalized? This happens every day from a social media standpoint. Actress walks into an airport with a book, people see it in the tabloids and now everyone is searching for that book online. You Google the actress name and in the auto suggest it says actress name + book if it had enough buzz surrounding it.
If you search Brad Pitt, what starts to suggest? First its his name, then its Brad Pitt fight club right? This again happens because of the search volume for his name and that movie. Now all of that is on a large scale. Imagine this same algorithm for a local business in Orange County that has 300 searches a month... Again, with enough buzz from real people you will be suggested.
In my business if doing this even brought me 1 client, it would pay for all my keywords combined and I am spending $1,800mo on using Search Box Optimization. The search volume combined on my 3 keywords I am ranking for is over 5,000 searches a month.
Now, I am also a complete skeptic of anything like this but after doing my research, looking every direction to see how it could possibly not work etc. The benefit still outweighed the bad. We all throw money away on stuff that doesn?t work in marketing. There is never a guarantee on SEO right and the time frame on that could be way longer depending on your keyword. Sometimes you just have to take a shot and again the more you look into this, the more it will makes sense. I even went in and read Googles patent on the suggested post to find a way to say it was a scam but that made me even want to do it more haha
Remember, SEO is against Google's policy too. What you may be doing now might be penalized next month. They want you to pay for ads! I actually spoke to two different people from Google about this search box optimization while researching it and they both told me not do do it... I asked them if I should do SEO and they said not to do that either. I then asked what should I do and they said use Adwords.. haha Thats all they want you to do is pay...
So "holy crap" that's my rant.. Maybe Drock101 didn't sell it right. I don't know him but I would look into it first. I?ll keep you posted on my results as well
Enjoy your day!
FYI - This is only a brief understanding of how it all works. There is obviously much more to the algorithm etc. (Real IP's, Location of search, time on results page etc.)
