I just had an offer on SocialSpark this morning and made an article about a certain product. The offer was $15. Well, this is not bad if to compare with my online job in Odesk wherein my writings only cost $2 to $4, these are for 300 to 500 words.
This is actually the first time I had an offer from this site. You would be asked for a review or just a mention on their product or site then you will be paid. I guess, this has something to do with my site's Alexa ranking. Since I actively updating my blog, my Alexa ranking is improving from 6,000,000 to 1,000,000 to 400,000. Adgitize is also a big help giving me 50+ unique visitors everyday.
Visit SocialSpark site. I just signed up and after few weeks, I had an offer.
