Affiliate Marketing Secrets

I want 2 eat fish & mc in cheese all
Day I only eat the fat free stuff every day ???
I don’t eat fire fish . My mom told me
That it is bad …

I have a e-commerce site and I would like to expand my social media campaigns.
With twitter, I find it relatively easy – it’s casual, a lot of random people talk to other random people, and each message is so transitory that I feel fine approaching people. (Not ‘selling’ per se, but saying hi or something)
With facebook, I feel like a spammer when I approach a stranger, even when he/she is obviously interested in my niche. I hate cold calling and I feel like one of those cold callers when I approach unknown people on facebook.
It’s especially hard because we’re not a big company known by everybody, and I also don’t have a huge budget with which I can run continuous facebook ads and/or ‘like us and get free stuff’ campaigns.
So my question is: how do people approach potential customers on facebook without being a spammer or spending too much money on it?
Is there a smart way to manage your facebook ad budget?
It is a very general question indeed, but any helpful comments would be appreciated.

Hi guys. I’m really interested in this crowded niche but what I don’t get is how reviewers (especially youtube) allow game footage. Is it ok to show game footage for reviewing purposes?
Also, how do websites like roosterteeth.com or screwattack.com work? Do they go ” oh, hello EA games, didn’t see you there. we have this gaming review website so send us free stuff and we’ll review it on our website.” How do they get so big they can afford to hire people? How do they make money? Whenever i see videos from they’re HQ’s they’re chockfull of consoles, powerful PC’s, walls decorated with MILLIONS of games (lol). So yea, all that costs lots of money.
I need a reaaaally informed person on the matter. Thank you very much. Hope i asked all the basics
