To sell in comments is not that difficult. The fact that you are reading this means that you have decided to at least look for some info on how you can make money by selling in comments. I bet, right now you're thinking that making money with comments is just another Ponzi scheme. It's all a bunch of hokey nonsense but is it?
If you were to go to the soldsie alternative source, if you want to know how to make a lot of money by selling in comments, the source is simple. All you have to do is to put in a post that you think is worthy of being commented on. If people like your post, they will update it and leave a link to your website in the comment.
In exchange, you give them a chance to click on your website link. The more people click on the link, the more money you will earn. You don't even have to sell anything. If you put in any link on the comment, just make sure you have a web address for the product you are promoting. That way, the people who like your comment will be able to visit your site and check out what you are promoting.
This is how to sell in comments. Now there is one thing you need to make sure. When you are participating in discussions, remember that it's only fair to treat other people with respect. Do not attack someone's character or talk about them in bad language. Always treat with respect even if you disagree with their point of view or you have different points of view altogether. You will never be liked but at least you will gain some popularity.
Here's a good trick. When you start a discussion in the forum, you should leave the screen open so people can see your web address. Every time you write a new comment, post a URL to your website in your comment. That way, when people click the link, they can go to your site to find out more about it. It will get you some extra exposure and hopefully you will sell a few products. People will click on links and you will earn money.

Of course, in order to sell in comments you must ensure that you have good quality comments. Avoid posting comments which are low quality because you will end up being ignored and people will soon ignore you as well. Be careful to only post genuine comments because if you post a bad comment, the search engines will pick it up and your site will end up buried among millions of other useless sites. So it's better to have a good comment than a bad one. Also avoid spamming the forums either by leaving obvious spam messages, or by making up lots of totally pointless comments.
