I remember about two years ago when advertising via your Twitter account became a BIG DEAL. Within a couple day span, several people hooked into Magpie and began incorporating paid tweets into their stream. The result? A huge backlash. People began unfollowing users who incorporated Magpie, while others thought it was a great revenue source.

I admit to trying it out for a day, but then figured it wasn’t worth the possibility of losing my followers to make a couple bucks. Shortly thereafter Ilooked into Twittad, which lets you pimp out your Twitter profile for businesses. I signed up, but never even once got an offer. And I haven’t thought about either of these sites much since, until today – when I got an email for the invite-only program, MyLikes.

So, I headed over to check it out and I also stopped by Magpie to see what they’ve been up to. I was amazed at all the changes they’ve implemented. You can edit the sponsored Tweets, and you now have to disclose every Tweet due to the new FTC regulations! Wow.

Here’s the low down on each one:

MyLikes:

• Invitation only
• Become an Influencer
• Earn money or help your favorite charity by recommending what you like
• Create Sponsored Likes for advertisers/sponsors that you Like
• Post on Twitter or your blog
• Get paid per click
• Your cost-per-click is set and constantly adjusted based on how influential you are and how relevant your Likes are

Magpie:

• Enroll and connect with advertisers via Magpie’s matching algorithm
• The system inserts posts or you can manually tweet
• You set the frequency of tweets
• Must include full disclosure, including payout amounts
• Different compensation models: Pay-per-view, Pay-per-click, Pay-per-lead and Pay-per-sale

Twittad:

• Sign up and wait for advertisers/sponsors
• Accept or deny the proposed ad
• Get paid for the length of time your ad is displayed on your profile

So what do you think? Have you tried out any of these services, or a different one altogether? If so, has it generated income and how have your followers responded?
