Nice post for webmasters. Some other methods to improve link buidings are Article Submission, Social Bookmarking, Press Release. From this type we can get link instantly rather than directory submission and others.

Nice article for webmasters. As per your point getting quantity of links are not important. Even a less authority links can improve your search engine position because of quality of link(Link strength)

Found this article very interesting. I use only social bookmarking and/or directory to promote my graphic site.
Thank you!

Great info you have! Well done and thanks for it I would like to know, is having a link to certain high ranking website, without them linking back to you can increase my SEO position?

The Authority of the links will be very important. I have learned in the las few days. Spending a lot of time, making backlinks, with less success.

I would also add that relevant contextual links have great benefits to ranking. Links from an aged, authority site are much more powerful than low quality, spammy links.
