What is Backlink? Importance of Backlink in SEO?

A backlink is a simple link from a website to another. Also, it is known as “inbound link”, “incoming link” or “one-way link”. Search engines like Google treat backlinks as an important factor for SEO. It means websites have a high number of backlinks tend to have high organic search rankings.

The main thing to understand is what it is for and how it works. Since it is an essential part of SEO, it can help bots to crawl your site and rank it correctly in search results. How to get backlinks is one of the oldest and most effective SEO tactics. Also, it is the most productive way to get organic traffic from search results.

Basically, there have two types of backlinks, “nofollow backlink” and “dofollow backlink”. Here “dofollow” backlink is more valuable than “nofollow” backlink. Let’s take a quick look at each type and how they affect your site.

Nofollow Link:

Nofollow link sends a signal to the search engine to ignore the link. Basically nofollow link does not help to get ranked in search engine. Since backlink is an important ranking factor and search engines use links as a key ranking signal. Hence, they do not count nofollow links in their algorithm.

In fact, they only count a dofollow link in their algorithm.

Dofollow Link:

When it comes to SEO factor, dofollow link has the ability to pass link juice. Dofollow backlink created from high PR and Domain Authority source can diversify your link source if you want to achieve the best results.

You can build links in places such as article directories, web properties, blogs, forums and many more.

If you are working on improving SEO, you must able to identify dofollow link. Here I am three ways to do this.

  • Use browser extension
  • Check HTML code
  • Use backlink analysis tools
Methos 1: Use Browser Extension:

Basically, a backlink is a vote from other websites. Each of these sites tells search engine, “This content is valuable, credible and useful”. So, more of these votes you have, the higher your site will rank in search engines.

Google formed backlink as an SEO factor in January 1998 when they released their algorithm “Page Rank”. Since then, Google made several changes to its algorithm, still, the backlink is a key ranking factor for search results.

There was a time when even low-quality backlinks helped to rank a website in search results. But Google had changed the whole picture when they released the Penguin algorithm. Now the truth is that all backlinks are not equal. In other words, we can differentiate dofollow backlink in two parts. One is quantity backlink, another is a quality backlink. A single quality backlink can be more powerful than 1000 low-quality backlinks.

If you want to rank higher, you should focus on quality backlinks rather than increasing quantity of backlinks. Here are some key factors:

Google is working on a patent that deals with trustworthy. This means you could possibly get into trouble for linking to a bad / low-quality website to generate backlink.

Factor 2: Target keyword in the anchor text

Anchor text includes your target keyword. It is also important in creating a quality backlink for your site. When a link incorporates a keyword into the text of the hyperlink, instead of putting “Click Here”, that word should relate to your keyword.

When a website links to another website, Google wants to see that the two sites are related. Building backlink for a food blog with a food blog is better than building a travel blog with fitness.

Google and other search engines ignore links with nofollow tag. Fortunately, the vast majority of links on the web are dofollow. For example, below sources are treated as nofollow:

  • Blog comments
  • Press release
  • Paid advertisements

If you built a backlink to any site, try to build the next link from a different site. A study found that it is better to get 100 links from 100 different sites than 1000 links from the same website.
