Leave highly valuable comments on other blogs in your niche.
Every niche within the blogosphere is made up of a few tightly knit communities. Like all
communities, so much of what is actually going on (passing links, giving tips, etc.) is all done
behind the scenes through email and IM. As a result, getting integrated into some of the
communities in your niche is essential to growing your blog. New bloggers often try to integrate themselves through email solicitations, "Hi my name is Newbie, will you be my friend?…"
This rarely works. You need to first make a name for yourself and make yourself valuable to the community. One way is to start commenting on the sites of community members within your niche.
By being an initiator of, or contributor to, good conversations on other blogs, other webmasters
will come to recognize your name.
Note: This takes a bit of finesse, so don’t go around dropping your blog’s URL in the comments
themselves. Rather, just type your URL in the URL field and let your ideas speak for the quality of
your writing and your site.

Include tons of outbound links in your posts. As a new blogger, your target audience is other bloggers. They have the links that you need to get to the top of the search engines and to get in front of other readers. So a big key is getting other bloggers in your niche to notice you. A good
trick is to use website referrals to your advantage. Almost every blogger checks their site referrals list on a daily or weekly basis (which tells them the last page a visitor was on before they landed
on their site). They use this list both to track new links and to see who is talking about their site.
By putting a lot of outbound links in your posts to other blogs in your niche, you can start to raise your profile. When your readers click on those links your site will appear in the referrals list of the bloggers you link to. This is free marketing for you. When other bloggers see your site in their referrals list they will often visit your site and are also much more likely to return a link to you.
