Old Post: This train of thought started below.
Doc Rampage joked a bit about how much traffic I get in a comment. I'm hardly high traffic, but I've done pretty well for being less than a month old. My average daily traffic these days is 25-35 visitors according to Sitemeter. It's partly luck and partly salesmanship.
Most of my traffic probably comes from Blogs for Bush. It's the only blogging consortium I'm on so far, although I'd like to join up with blogs4God, but they prefer blogs that are at least a month old. Joining these sorts of consortiums are probably the best way to gain traffic and make a name for yourself. Consortiums, aside from linking to all the blogs on their main page, usually ask their members to include some form of their blogroll as well. Blogs for Bush is especially good for this because it uses a rolling blogroll that puts the blog with the most recent update at the top, which means I'm pretty much guaranteed a few hits every time I post. Of course, just joining isn't enough... participating in Carnivals, posting in comments (with links to specific posts), and using trackback with those blogs that have it are all good ways to get attention.
Carnivals are pretty much consortium specific, but comments and trackbacks are good ways to get attention whenever they're available on a higher traffic blog. Then, of course, there's occasionally selling a post to one of those high traffic blogs by e-mailing a link. I haven't been doing that too much recently... the odds are pretty low considering the amount of e-mail they get. Sometimes you get lucky, though.
Also note that some blogs also have a reciprocating policy--you put them in your blogroll and they put you in theirs. Some of them use automated blogrolls to do this, powered by a service such as Blogrolling.
And of course, I post at a pretty good clip. I have something new every day, even if it's just a note that I don't have much today. Aside from giving visitors a reason to check back often, just in case I updated, it puts me at the top of those rolling blogrolls more often.
Don't overdo it, though. It's frustrating when you have good material that nobody's reading, but there's no point in getting attention when you don't have good material. You can get them to come, but they won't come back. Right now, I'm really not making much effort to sell my blog. A comment when I have something on my blog that's relevant to someone else's blog post, a trackback ping whenever I refer to someone else's blog in one of my posts, and participating irregularly in the Carnival of the Bush Bloggers. I like the traffic I currently get, and I want to make sure those who are coming by have something worth reading, which means I better stop with these self-indulgent posts about blogging and get back to politics. I never really did rake Glenn Reynolds over the coals properly...
