Post regularly. It doesn't have to be every day but, as Miss Kay said, if you post regularly people have a reason to want to come back. If they come check your blog and there is rarely an update, they'll stop checking.
As for the rest, it really depends upon what your goals are. A blog that makes money? Or a blog that a lot of people want to read? Generally, you won't make money unless you have a blog people want to read, anyhow.
Also, remember it takes time. I've been blogging since '05 and for a long time I could count my readers on my fingers and toes. Now I have tons of readers but I try to keep my blog the same as it was when it was ten friends who read my babble - that's what drew the readers in the first place.
If you're writing a personal blog, keep it personal. If you're mixing reviews with personal stuff, make sure the mix is good. Some folks will want to read the reviews, some will feel they're a pain in the ass and just want to know what's going on with you. If you get too review heavy, you may lose "regular" readers.
If you're writing a review blog, make your reviews good ones and try to keep them fresh and entertaining. Add pictures and video, be entertaining, don't write dry, detail heavy reviews with no personality in them.
Get your name out there but do it in a polite way. Don't go tweeting your new blog every two minutes.
Go to other blogs and leave relevant, thoughtful comments. People will follow your link from those comments to your blog very often and if your blog is interesting and you are genuine, they may become regular readers.
Don't count on things like Pleasurists to get you traffic. Most people don't actually read the reviews on Pleasurists so your "traffic" and stats are primarily pingbacks. Real traffic is always better than mechanical.
Uh. There is more. I could babble about this all day. But, yanno, my fingers are tired and I need to go blog.
