Write your own post
A lot of times I see bloggers linking a post that they found interesting. There is nothing wrong with this. In fact, it’s probably good to give a link to it. But, give a link to it after you write your own take on it.
Many times the post will be a sentence about what the blogger found and then the link. This isn’t doing anything but driving people away from your blog. If you’re not the one that can write up valuable information, nobody wants to stay there. They’re going to go to the people who do write up valuable information. The people that you link to.
When you find an article that you like, you should research it. Read up on everything that was mentioned in the article and learn as much as you can about it. After you’ve learned about it, write up your own take on it. Formulate your own ideas and post them. Put a trackback link somewhere in your post when it mentions something similar to what was said in the other blogger’s post. This will let the reader see the article that gave you the idea and your article. This lets your readers get more information out of the subject than if only one post, with one viewpoint, had been written on it.
Now, when I say viewpoint, I don’t mean that you have to have a conflicting viewpoint. You can whole heartily agree with everything that was said. But, still, you can make some points that weren’t made by the original poster.
