Bum marketing doesn't have the power that it once did but can still be effective in low quality link building. Of course the best links to build are natural ones that come from getting good press or having people link to you because you have great content or an interesting business. The ways of linking you gave above are a great base for people and I agree Hub Pages does bring a lot of traffic for the work involved in making a page and maintaining it.
BUM Marketing is simply a technique of doing business on the Web. This is someone's way of making money on the Web by selling you on their idea. Their strategy is to use tools and techniques that don't cost or are low cost. You can Google BUM Marketing and read all you want to know about what they do and how they do it. I don't subscribe to them but I do read some of their material.
thanks a lot kbhuffaker. i guess i should have just googled it, but it was the first time I heard about BUM marketing.
Most of these tips are better for increasing seo rankings then getting traffic directly, but I guess increasing your seo rankings can lead to more traffic if you target the right terms =)
Good post, but not all of those work in the same way and with the same effectiveness. In fact, most of them become a bit irrelevant when you compare the work you need and the results you get.
