I don't know its OK if i put this question in here. Today i receive 2 invitations form "VPN connection" seller and other "Data recovery tool developers". They told me that if i write an article for their products they can give me Free license key giveaway for my blog few visitors. Are they Scam or this kind of promotion is true. I have no idea for this because of im a newbie for this field. If i write and article and publish it my blog then they ignore me? I hope you guys have more experience for this kind of thing, so please help me.
Well think of it this way, if they don't keep their part of the bargain you still gain new content for your blog. Anyway, you could also ask for more details from them if you really want to make sure.
