If you're looking for Google rankings, no. There is no inexpensive turnkey way to increase your Google ranking (or everyone would do it!), you need to do it the honest way with good site design and good content and good readership.
If you're looking for customers, no also. Probably everyone who joined is a business owner looking to increase their traffic to increase sales - your traffic might increase, but everyone visiting is looking to make money, not spend it!
I just spent a few days with a client who was about to spend a few thousand $$ on a guaranteed website marketing strategy ... finally was able to make him understand the gimmick... Good Luck!
