I stumbled upon a an old post on ProBlogger about increasing your traffic in just 30 days. At first, I didn't notice the date it was published, but I really believed in what it was saying. Then I noticed the date, and it made me laugh because the tips still hold true today. Tip 3 was worth highlighting:
Finally, I made effective use of trackback links to popular sites. If I commented on a post on another site I would make sure that I set up the appropriate trackback for it. The results from this are varied depending on the site and post that you are linking to but since I liked to comment and interact with the wider blogosphere anyway, it was free traffic!
Even though this is from 2005, it is still true today. If you want to gain respect in the blogosphere, you have to earn it. Just writing your posts and sitting around waiting for the readers to flock in doesn't work. You need to proactively get out there and make your name known.
However, I caution you against belatedly plugging yourself where ever you go. Don't just comment on someone else's post because you are looking to get clicks back to your site. And don't make your comments into a big advertisement for yourself.
Instead, actually contribute something worthwhile to the conversation. That will gain you more blogging street cred
