As a freelance blogger who gets paid to write for a few different websites, I often get approached by product (themes and plugins) developers who want me to include their items in the posts I write for my clients. Sometimes offers of payment are mentioned for featuring their product in one of the articles I write for a client. So far I've always said thanks but no thanks. If they want to send me a free copy to test out I will take it, but with no guarantee that I will feature the item when I write a related article. However, I'm just wondering where others stand on this? Would you take a payment for including a product you were going to mention anyway? If the site you are writing offers a paid promotional post service where product owners can pay the site owner for a featured post, would this affect your judgement? Would it be wrong for a freelance blogger to be 'sponsored' by a product or service and be compensated for recommending that product or service each time the topic comes up? I guess its like being a 'brand ambassador' or something. Thoughts?
