*This post was originally entitled the “Top 7″ but as I find more twitter revenue avenues to use, I’ll update accordingly.

Do I tweet for money? Yes, I admit I do.

Now I don’t just tweet out blatant ads.  In fact I reject over 50% of the ads offered to me because they are irrelevant to my audience. I’m not going to jeopardize losing subscribers that way.

So many new “Twitter Networks” are popping up that I thought I’d list the ones I’m currently using (yes, this list is for me to remember, too). I’ll put in alphabetical order as to not show favoritism.

Ad.ly – I signed up for this one after Shoemoney recommended it (he’s so gonna win that Macbook Pro for referring the most friends).

Magpie – This was the first twitter network that originally randomly published tweets on your behalf, but they’ve now joined the cool kids club and let you approve/deny tweets.

MyLikes – Create sponsored likes (tweets) and get paid per click. Plus refer friends to win an Apple iPad.

Revtwt – Easy enough to use (can manage multiple twitter streams under one account). Lots of international opps. 20% Referral Earnings.

Sponsored Tweets – Ok, this one has been my favorite so far.  Why? Because I’m a fan of Izea, and I’ve made the most money from them so far. So much for  impartiality.

Twittad – Twittad also offers the opportunity for advertisers to sponsor your twitter background with advertisements.  I’m okay with pimping out my  background on my non-personal twitter accounts.

My only complaint about all of them (except Revtwt) is having to have an account for each separate twitter account.  I have several twitter accounts – that I manage through Hootsuite – and it’s a pain to have to have log in, log out, log in, log out, etc.

And yes, dear FTC, all of the above are referral links where I may earn a referral fee if you join and make money as well.

Additional Twitter Advertising Networks that I found through Google that I have not personally tested yet:

Assetize – no referral program

BeTweeted – referral program for advertisers only

Twivert – this one looks the most promising

Am I missing any? If so, leave your referral link, and I’ll sign up through you.

Be sure to follow @workinmypajamas for post updates.  I’ll auto-follow you back and try not to blast out too many twitter ads.

Heather from BC gave me this fancy smancy green IZEA tee while in the blogger’s lounge at last month’s Affiliate Summit in NYC*.

IZEA is a social media marketing company and the world leader in sponsored conversations. They operate a network of over 250,000 bloggers and 25,000 advertisers around the globe.

SocialSpark.com, my favorite IZEA property, is a blog marketing network that connects advertisers with bloggers through an online marketplace. I personally have taken several “opportunities” that include Pay-Per-Click (can be promoted via Twitter and Facebook),  Sponsored Websites (that put hover ads on your websites), and Blog Posts (that I fully disclose are being sponsored).

I think Social Spark is not only profitable, but fun (and I wish they had an affiliate/referral program).  Yesterday I took an hour to review a few opps and ended up writing two blog posts about what I learned on those sites. Most posts require 200 words which isn’t hard to come up with.  Considering the price paid for post varies from $5 to $300 per post (mine were both somewhere in the middle of that), it turns out to be a pretty good hourly rate!  Plus I added new unique content to my sites, so it was a double bonus.

Check out BenSpark.com’s SocialSpark Saturdays for great insight on how to most of out of SocialSpark. You can join me on his “I’m Not A Famous Blogger” Crew.

Recently IZEA also released Sponsored Tweets that matches tweeters with advertisers.  This is the best “get paid to twitter” program I’ve seen thus far as you can review and accept or reject the tweet that that the advertiser would like to send out.  Some advertisers even let you write your own tweet. I will decline a tweet if the “ad” doesn’t fit my audience, as I don’t want to risk losing valuable followers if they think I’m spamming them. But if an advertiser wants to advertise a shoe sale via Twitter to my @shoeaholics followers, everyone benefits! Sign up at SponsoredTweets.com.

*I also got to meet Ted Murphy, Founder/CEO of IZEA, while in NYC.  Watch for a “Famous Tongue Photo” in an upcoming post!
