How to monetize your tweets – use top twitter ad networks
There are quite a few twitter ad networks in existence who claim to let you make money doing what you are already doing: tweeting. Some promise to pay you while you tweet about the links they provide, others simply pay you to tweet about stuff, stuff from advertisers in the ad networks. To avoid the negative “soul selling” public images of “tweeting for money (a.k.a, spam tweets)”, 3rd party twitter ad networks have been getting sophisticated on its ways to give users options to choose what to tweet, when to tweet. Although small, TweetROI.com is very particular about it, founder Brian actively blogged about ethic sides of tweeting for money. The two kinds of twitter ad networks, big or small, old or new, are differentiated mainly by the transparency they give back to twitter-er. Following is the a list of such ad networks that worth looking at. (notice that I left out tweetbucks.com, due to its affiliate commission payout mechanism being completely different from other players listed below)
Leading twitter ad networks: RevTwt and TwittAd
1. RevTwt.com

Previously known as TwtAd, RevTwt is the biggest twitter ad networks to date. RevTwt lets you tweet about info and links from advertisers in its network. For example, one ads offered to me is “World of Warcraft – Auction House Mastery ($0.050/click): World of Warcraft – Get Mayley Winter’s Warcraft Auction House Mastery 34pg Free Report Here!”.
It’s understandable that these ads are hardly relevant to what I usually tweet. It remains a challenge to date to find the advertisers that will fit people’s tweeting style. If RevTwt as the biggest twitter ad network can not get my favorite airline to be the advertisers so I can tweet about my last trip, I don’t know who else has more suitable advertisers. Then, of course, if I am a WoW fanatic, it would have been match made in heaven, for 5 penny though.
TwittAd.com

TwittAd is 2nd largest twitter ad network. I like its legitimacy, two options to choose.
Option1: Choose the advertiser, post their tweets, get paid
Option2: Opt-in campaign based on what interests you.
I feel Option 1 has more control for me than option 2. I will definitely give it a try just to have a taste of it.
Smaller ad networks with less options.
Twivert.com, Adcause.com


Both ad networks let you tweet for advertisers during a time slot you choose for the day. Ad cause has been around, possibly the earliest player in this space. However, either the payout amount or inherent marketplace efficiency not as good as top guys, they have quite a catch up to do.
Newcomers, reformers
I consider Sponsoredtwts.com from IZEA (still in beta, lot of hypes from TechCrunch), TweetROI, maybe Paymetweets.com new comers and reformers. All of these sites try to build a relevancy into tweets-as-ads, or recommendation tweets based on twitter-er experiences and interest. I often get a “Thank you” note from product owner accounts on twitter when I tweet about their products, for free. For example, when I twitted I saved $400 a year switching from esurance to progressive, their account manager @progressive dropped me a notes saying “Thanks for switching to Progressive! Glad to have you as our customer!”.
