Link Popularity
Link building has been one of the major areas of attention by seo’s when it came to improving ranks in search engines and they used to get links from even irrelevant sites. But now things are about to change as google is working on an algorithm to evaluate the content relevancy between pages, where the link is and the page where the link points to and this will affect the search engine rankings a lot in the near future and increase the link popularity. And some people who have been building irrelevant links shall see their ranks drop like anything, and those sites with very relevant links coming from within the content shall see an unprecedented rise in their results.
