As you all know, Google give too much priority to back links. But there is two parts of back links, First is quality back links and second is only back links. We do lots of off page works just for backline. Google do not counts the quantities of back back link, but checks the qualities of back links. So, which are the commons techniques to create quality back links?

Writing content that is deliberately designed to attract links towards it is one...Here are some other techniques on my link-building list:
- Submitting RSS feeds to HQ feed directories
- Submitting website to social bookmarking sites
- Participating in social networking sites and related communities
- Writing guest posts for blogs related to your niche.
- Creating link baits

So long as it is done all organically, it should help.
I use 'Keyword Country' to design my link building strategy around traffic pulling keywords and to monitor link-building strategy of my competitors. Pretty satisfied.

Quality Backlinks has a Synonym - FORUM. Generally search engines index forums so posting in forums and blogs is also a way to get quality backlinks with the anchor text you want. If the forum or blog is a respected one, a backlink is valuable.

In this case, I must say forum posting and article marketing are very effective way to increase quality backlinks, And ofcourse it will helpful when you promote your website in ethical way.

Quality links is just meant by natural links not just spam way or link exchanges are not called good back links they are just back links
