570513 Appear on Google for thousands keywords

I saw some software related site which appear on google for a lot of keywords, in fact, such many that it's unrealistic that it's natural. This sites have scripts which made them appear on google for thousands keywords (maybe from a database?). I want this kind of script for my website. I can work with escrow and before releasing the payment i want to see the proof of that this is working and by "proof" i mean actual long term keyword micro niche result on google. We will target no competition keyword just to see if it's working.
