How Off Page SEO can help in ranking?

Off page optimization is a game of backlinks! The most difficult task is to generate a good backlinks.
The calculation is based on DA and PA of any website where you will generate the backlinks. Their are two ways to figure the website is having good DA and PA, first is visit moz.com or try to check the visitors in that particular website where you will generate the backlinks.

The calculation is based on different types of methods. This is what I personally Follow to generate the backlinks in a different manner.

Back Links	Pages	DA	PA
Article Submission	5	90% -95%	90% -95%
Blogs	5	90% -95%	90% -95%
Social Book Markging	5	90% -95%	90% -95%
Classified Ads	5	90% -95%	90% -95%
Business Listing	5	90% -95%	90% -95%
Total BackLinks in a Day	25

In a day to rank the website you should need to keep the backlinks atleast 25 not more than that

Day	25
Weekly	175
Monthly	750

This will impact on search engines drastically along with this keep in mind before creating any backlinks thats it should be Do-follow backlink.
