I did some keyword analysis in http://ads.youtube.com/keyword_tool I collected the best keywords, and made a blogger's blog in the name of keyword. Added title tag and meta tag etc.
Then I head over to linked tube and configure my affiliate link with the selected youtube video. I copied the embedded coding, then went to blog and pasted the codes in the blog posting option; I gave a suitable heading which is taken from selected keyword list.So the blog post link would be blogname/heading.html, I copied and did some social book marks with digg, mixx, delicious etc. I repeated the process for 3-5 products; I could expect at least 2 sales a day with this method. I hope you would be enjoyed with this method.
