How to promote your blog

Post regularly and try and be different to all the other blogs in the same sector as you, to create link bait. Comment on other poeple's blogs to get yourself seen. You could try submitting the blog to a couple of the free directories (might work, can't hurt, but don't spend more than a couple of hours doing this). Do a Press release about the launch of the new blog if you can think of something newsworthy to write about. Try and organise a blog marathon if you know other bloggers in your area, etc. But the biggest one with blogs I reckon is quality, regular postings.
