This video courtesy of ExpertWordPress.com is about getting backlinks to your WordPress blog from other blogs. The author provides some very good advice about getting backlinks from other WordPress blogs by way of leaving comments on the blogs.

The key of course is making sure that your comments are relevent to the post you are commenting on. Spamming other blogs will only make it harder for you to get the backlinks you want, but will also give you a bad reputation among other bloggers.

Make sure you keep to the subject at hand and offer something of value with your comment and you will get more backlinks.
