Blogs are a strange breed of animal. Very similar to forums in some respects when you have multiple bloggers interlinking "conversations" from each other. An
excellent article on the differences can be found at Lee Lefever's
CommonCraft website.
One key to promoting your blog and getting the backlinks is to get found by other bloggers who hold similar interests to yours. Getting your blog listed in some high profile directories such as Technorati, Syndic8, and some others will go a long way to getting found by the other bloggers (who are always on the lookout for something new to read). Look to Robin Good's
RSS Top55 Directories for one of the best lists I have come across on this matter.
One thing is certain, if you are using your blog for commercial gains -- you will not have too many picking you up and linking to it. This is to say, that your posted articles should not be mini-promo ads of your products. Writing about subject matter that relates to them in a general and unbiased way without the promotion is the answer. You can always have a footer or sidebar link tucked away on the page somewhere.
Blogger is NOT the best method of blogging IMO , especially if it is being hosted at Blogger itself. Generally you are apt not to be taken seriously by other bloggers. I am using Blogger myself, and learning this the hard way.
Blogger does not have Trackback capability, which automatically picks up on other bloggers who "cite" your posts which provides a link back to your blog. Hosting your own software such as MovableType, WordPress, and some others with Trackback hacks integrated into it is the way to go.
If you have Blogger and want Trackback added, then
contact their support team and request it. If enough people request it, they just may provide it. There is also a service (I have not tried it yet) that is provided by
HaloScan
Blogger does not support RSS, they use Atom. You will need to get a conversion on your feed if you want wider syndication. I recommend
FeedBurner for this.
Getting your feed picked up and published on another site is pretty kewl. I have three sites that are running my RSS feeds on their sites now. This will get you more links back to your blog.
Commenting on Blogger requires that they have a Blogger account. Comments are a good way to get people involved in your blog, especially other bloggers. Of course, spammers love it too. ;-) I use an outside service to handle comments which does not require them to sign up to use it. Plus it provides the static link (which gets the people to post). You have to be on your toes though with the comment spammers. I am using
BlogBack, but there are numerous services that will provide this for you (including HaloScan above).
For a list of blogging software (non-services) and their features, look at the
Blog Software Breakdown at Asymptomatic. You can test drive most of these at
OpenSourceCMS.
