There are lots of snake oil scammers out there trust me when I say this. For instance for one many clients websites there is a physio site that is completely dominating that niche from left right and center claiming to be specialist physiopherpists however they aren't at all in fact they are just another big company with lots of money to buy lots of links to get themselves to the top the search results... if they were really physiotherapists then they sure wouldn't have a builders supply website as well which they do. All the injury advise they give is also very questionable.. why would everything be cured by one of their products.. hmm! Because they are at the top of the search results for keyword such as "insoles" and "knee supports" means that they are easily raking in millions... where real legit businesses are barely making peanuts. It is also worth noting out that the prices they set for there items are just stupidly high too.... Coincidentally someone else has already posted about this here.
Recently I also searched for how to grow taller.. dont ask me why its a little embarrassing anyway the search results for that search are really really bad... page after page of snakeoil there.. and dangerous snakeoil trying to sell people human growth hormone pills.. eeeeeeeeeek!
