best marketing technique

It is practically very difficult to answer such questions because online marketing has very wide area. However Organic search engine listing should be the key factor those want to achieve their position in SERPs through online marketing.

for me my best marketing effort is trough combination blogging and adwords with additional longtail research,it is basically marketing base on community gathering,creating place so that people love to read my blog,and once the blog hit there popularity I post a sincere recommendation about the good and bad of the product I sell

1) Write an article and submit it to good article submission sites.
2) Write a press release and distribute it to media outlets.
3) Try to get reviewed by blogs.
4) Submit your website URL to directories.
5) Add your links to Social Bookmarking websites.
6) Join forums and get reviewed by forum members. (do not spam)

Links exchange with relevant content

blog post

Hub pages,twiter,stumbling

and more and more ,just don't give up until archive your goals.
