Optimizing SEO is an important part of your blog business. If you don't optimize SEO then you run the risk of losing valuable search engine traffic and PageRank (PR), which has the potential to greatly improve the profitability of your blog on the Internet.

Commenting on other people's blogs is a nice idea, comments on blogs within your niche and with high pagerank will give your blog high quality backlinks.
