PageRank measures the number of incoming links to give a web page and its relative strength. generally, the more links you have that points to your website are better for your ranking, and it increases the PageRank of the linked page. It's also called link popularity.

The greater number of other links on a page, the weaker strength of each particular link. Each link is a "Vote" for your page which is linked to, and the strength of Vote is divided equally among all other links on the page.

Google tries to give the most relevant result from any given search term. Google does so is by searching and analyzing keywords on the web pages of another website that link to your website. It means your site is linked to their link text, the title of their links page, and the content of their links page. 

 

You could have 100s of pages linked to your site, but if the text of those links doesn't match your primary keyword or if the linked page content is not related to your site those types of links or sites won't add any good boost to your ranking.

If the only quantity of links to a site was important, then every site on the web will link unlimited links with every site and the largest number of links would be number 1 with given keywords,

1. Text of the incoming links : Does it contain your keyword (IMPORTANT )
2. Text of other links on the same page: do they also contain your keyword??
3. Title of the linking page: does it contain and relate to your keyword or site.
