Article submission, free directory submission, forum posting - which one is best

[sGuru]

yes, I agree, forum posting is most effective and then article submission, all have their own importance, like directory submission helps to get link popularity, its easy way as compare to article submission, and forum posting drive traffic to your site, I don't think its help to improve ranking as compare to article submission, Article submission helps to improve ranking.

i enjoy forum posting the most to be honest, as i like to read, the exchange of ideas, and a chance to say an occasional thing or two, as i have read quite a bit on seo the last few years. i do regular directory submission for the backlinks and it's work, and i wonder about its effectiveness. since i'm not that good of a writer i haven't tried the article submission route yet.
as far as theory goes, gaining quality and quantity of backlinks is the thing that helps in the serps and page rank....

For me these 3 are best for targeting keywords as long as we are not spamming and niche to our website.

I think all of three are important for seo. If you doing do follow forum commenting, you will get keywords ranking and traffic both.
