Backlinks are basically votes from other websites. Each of these votes tells search engines: “This content is valuable, credible and useful”.
So the more of these “votes” you have, the higher your site will rank in Google and other search engines.
Backlinks (also known as “inbound links”, “incoming links” or “one way links”) are links from one website to a page on another website. Google and other major search engines consider backlinks “votes” for a specific page. Pages with a high number of backlinks tend to have high organic search engine rankings.

Not all backlinks are created equal.
In other words, if you want to rank higher in the SERPs, focus on quality backlinks.
Put another way:
A single quality backlink can be more powerful than 1,000 low-quality backlinks.
As it turns out, high-quality backlinks tend to share the same key traits.
As it turns out, Google feels the same way.
This concept is known as “Domain Authority”. Essentially, the more authority a site has, the more authority it can pass on to your site (via a link).

Because that link comes from an authority site, Google puts lots of weight on it. In fact, I noticed a boost in my organic search engine traffic right after TechCrunch linked to me.
