Tweeting nothing but links. If it's an affiliate link or not, it doesn't matter, it's when everything is links. When you see a link on Twitter, you're not exactly trusting of that person because you may not know them, this is natural. It may be one of the Twitter followers that you've already had conversations with and are developing a relationship, those people will be more likely to click. But if it's links and it's nothing but link after link after link, then pretty soon you're going to be like many people and you're just going be unfollowed.
The second big no-no that I see again and again and again is tweeting too much. I just completed a Twitter for Beginning webinar and that was one of the things that we talked about a fair bit. What is tweeting too much? It really does depend on you, the receiver of the tweets, what you want to see in your Twitter stream, but if you've got 190 followers and they're following 220 people and you've tweeted 5,000 times, the chances are you've tweeted too much. You really have to stop and think about how often you are sending out a tweet and whether or not you do need to send it out. A good question to ask yourself is whether or not it is valuable.
The third is a little trend that's been happening quite a bit lately is where people will make like they're re-tweeting something that I tweeted. They have falsely included my name... the at sign, and then my Twitter name, and they put the RT in front and then their name. And it's not my link. It's not my tweet. They're sending out -- a lie. They are actually sending out something under my name that is not mine. It's untrue. So it harms the person, myself, because then other people believe that I have been tweeting all these different links. This behavior will get you unfollowed.
