Backlinks and link popularity
In SEO, off page elements have become increasingly significant as they associate to rankings.
Particularly, strong link popularity can literally make or collapse a site on the search engines.
Backlinks are defined as links from different sites that indicate yours, and they’re probably the most significant part of search engine optimization and ranking advantageously in the SERPs (search engine results pages).
Most search engine optimization professionals will tell you that the key to ranking advantageously in the SERPs is to cumulate more high quality backlinks than your rivals for any keyword phrase you’re aiming.
This requires time and hard work when attempting to rank for highly competing keywords, but it can be done.
