Actually writing a crawler program is not that bad, you can use the existing tools, but write your own one probably enable you do every function you want. While I can not provide the code, I searched and find an algorithm for this. It’s an interesting program.

There are five ways to tell if your blog is on the right track, comments, subscribers, links, friends, and niche. Based on this point, programcreek.com is not on the right track at all. There are not a lot of comments, almost no subscribers, few links. This is true, because I’m not spending much time on this.

Marketing skill is based on good products. Here, it is valuable content. So the only way to let the blog go to the right track is to spend more time making valuable posts.
