Can you explain certain rules which you follow in doing link building?

I always do only content outreach and not involve in shady link building. Always search blogger who needs good content. Do not play with Google or any search engine. Use variation in your backlinks keywords. like asp dot net development company, asp .net developers

Hi Friends,
I use many specific rules to define the quality of links. I will look at following factors before submission :

• Quality of back link(PR, PA, DA must be good)
• 
  Relevancy of the content between 2 sites
• 
  Proper use of anchor text.
• 
  Avoid site-wide links
• 
  Avoid links from low-quality sites.
