This is a good list, however NOT everything on it is actually applicable or even worth the effort for a blog or sites which sell virtual products or services. Some offline advertising methods do not really render much effect or results for virtual products because they TARGET Internet Marketers, whom are not looking for these things offline.
Though the list is comprehensive, one important thing to consider is to pick a few that will drive the most traffic to your blog. Think of the lowest hanging fruit, the tactics that will help drive the most visitors and convert them.
What has been your most successful method in driving traffic to your blog or website?
SEO Keywords, Social bookmarking, link exchanges, forums back links, opinion polls, blog directories, advertising eBooks, niche videos?
Very impressive! So many things you've listed here. I think regular informative postings, proper communication with your niche bloggers and quality backlinks are the main factors that play an important role in driving traffic to your blog.
