Outbound link is of its pages to other pages. Number of Outbound links to other Web sites you greater the SE evaluate your site lower. Conversely, if the partner sites also appear to page your backlink, which called inbound links, ie SE see web you and partner link 2-dimensional (2-way link) so the web will be Google himself .

In many cases it would be outbound links to sites that get good PR. The key issue is, those links must be consistent with the information content on your website. An article followed by a lengthy list of links will not bring much benefit for your website.
You should strive to link to good blog posts in blogs that fit your theme, the resources related to the problem you want to address, and links to content that does not exceed the level of information you have. Such sites, of course, must be consistent with the content on your site, but it is not necessarily the same point where you give because you know the information you give more accurate.

Role of outbound links in Google’s formula for calculating PR. Suppose you have one page A and you want to calculate page rank for the site including:
PR (A) = (1-D) + D (PRP1 / 0 + PRP2 / 0 + PRP2 / 0 + … + PRPN / 0)
D here is a basic element for calculating PR and it is based on links from other websites. Normal value is 0.85 in most of the algorithms. PRP1 to PRPN is Page Rank of all pages that it links to your page and 0 representing each page of outbound links. For simplicity we can define as follows:
Page rank of A = 0:15 + 0.85 * (Value of PR after the share for each page that links to this site)
Now do you see clear links between Outbound links and PR rather then. If the amount of outbound links on the page linked to a too large then surely it will not be worth much. Suppose you have 2 options 1 buy link to a PR 6 site and the number of outbound links of 500, 2 is the link to the web page buy that ob PR 3 links <= 50. Then you should choose which one to buy it.
