What baklinks means
Quality backlinks is one of the most important factors in Search Engine Optimization.
It is not enough just to have a lot of backlinks, it is the Quality of backlinks along with the Quantity that help you rank better in Search Engines.

Quality Backlink
1. It links to your website with the keyword (keyphrase) that you are trying to optimize for.
2. The Theme of the backlinking website is the same as your website.

You need backlinks (= link popularity) to improve your search engine ranking. But that’s not all:
You need backlinks from different domains (= domain popularity) based on different IPs (= IP popularity).
This is more valuable for your seo ranking.
