... havnt you heard of advertising?
Even though they might not be making the cash back off paying $30 for a signup to a $1 trial... heaps of people push their sites because of the good payouts, in turn the brand, the name, gets lodged in the 'webwankers' head.
So webwanker, John Doe... 3,4,5,6months after seeing your gallery with a All Internal link decides he wants full length movies, so... John Doe does what most people would do and types in
www.allinternal.com
No webmaster was paid for that... PerfectGonzo get the full amount, then it recurrs... again PerfectGonzo get the full amount, but the only way webwanker John Doe new about AllInternal was because him, along with 1.8million other surfers saw your gallery on the hun.
*PerfectGonzo just used as an example, I'm not associating them with shaving.
