How to define what is quality link?

 

back links from a site with less OBL and which is indexed and cached is called quality links with prior condition of relevancy to ur site

 

Quality links come from high traffic (quality traffic) sites, that are related to yours, with high quality content and valid HTML. Also lots of inbound links but a few as possible outbound links (except yours). Your link should have a good variety of your keywords in and be featured high up in the content section of the page.

 

Do Follow from relevant niche, also from websites with very little outbound linkx

 

get backlinks from sites that related to your niche, be it forum, blogs, that's quality backlinks. Best if these forum blogs got certain pr too for google faster cached

I think comment links from top blogs in your niche, Article links from top article directories like ezinearticles, forum links from top forums like worriorforum, digitalpoint and sitepoint are links of pure quality.

Tip: if you want to increase your page rank you should consider links from different ips i mean only one or two dofollow link from one individual site. and don't forget to add nofollow codes in out going links of your site, which are of poor quality.
Oh! i forget one important Tip,
one should consider the quality of incoming links not the quantity if you want page rank increase fast.

 

accordingly not just from related website but a top rank site

 

High PR, no drop domain, same niche with your site and less OBL

 

.gov and .edu sites work well

 

Links from the quality sites with high PR. For example wiki or cnn.

 

Links are considered good links if when you click on them they don't redirect you to another website before going to your own website.

 

as per my point of view When we submit, add, comment high pr or well known sites that links are considered quality links.

 

They will also only be considered quality if they are related to your topic. If there is no relationship it will look paid
