Directory submissions, article submissions, social bookmarking, social networking..... Something tells me you already know this and your just trying to add to your post count. I mean according to this post you shouldn't need to ask such a simple question
Well the best way to get your backlinks for your site would be forum posting and the profile page backlinks. I see that you are using your signature link as your site name, however use your anchor text for the site URL with one of your main keyword, instead of just putting up the URL. Also try to make some genuine and meaningful posts here and be a regular commentator, you dont have to do anything else
Article sumission, guest posting, forum posting, press release sumission, bookmarking and social networking.
Article submission!! then write articles for diffrent sites so that they will provide strong backlink!
And then one day Google decide that they don't want you and erase your site from search engine for no known reason! This days and new standards from Google its a lottery to get ranked your site high.
That's because it is not a recommended practice. There usually crappy, low value links. Plus Google hates it. You are right though, it hasn't been mentioned. =)
Signature links and guest posting on blogs, article marketing - and various other methods. Why focus on link building when your content isn't up to par? Google wants quality content and if you have that, with great links, you'll rank higher. It doesn't matter about how many links you build, its about the quality of them.
This question has discussed here before a number of times. Please browse through the forum before going to post such a simple question.
best backlinking technique :- Put regularly good quality unique content on your site. and let the others build links for your site. <= this is what google wants.
Sure, write quality content - get links through related websites - get links as a guest writer on blogs - forum signatures, but focus on your content before trying to build links - that way your content can be better/you rank higher.
Forum posting is the best and unique giving more number of backlinks. Then you can try article submission to various directories.
