There are a lot of tasks and elements involved in doing SEO. One of the essential factors is backlink. Backlinks are necessary if you want to build your website and pages’ authority. Having a website and web pages with high authority has a significant impact on search result rankings.
What are backlinks?
Backlinks are those links that point out to a domain from another domain. You can acquire backlinks through link building. Many SEO experts agree that link building is one of the hardest parts in doing SEO tasks.

Why are they important?
They help Google find your pages for ranking.
This is the simplest explanation behind the question. Google has spiders who crawl different websites to find information that is related to what the people are searching on Google search engine. If your website contains information that could answer the search query of the user, you want Google to crawl your pages too aside from other sites. And if there is a lot of information that will lead Google to point to your website, then you’ll have a higher chance of performing better in Google search engine, as well as other search engines too.
Google is very committed to catching trending topics and hot discussions. It can be known when it is a hot topic when you see that is being found on the internet many times. In connection, if your content can be found in different places online (many sites), then, Google will take a look at it. Having many backlinks will give you better chances of being found fast. This will lead to faster indexing and increase in ranking
They elevate your Domain Authority
Ever wonder what made those popular brands rank on higher spots in search engines? It is solely because of their domain authority. Search engines consider the domain authority as a metric in deciding the ranking of the website in search results, among other elements.
Domain Authority is a metric created by Moz to purposely rate a website from a score of 1 -100. The higher the score, the better your website will rank on search engines. It can be seen as a competitive metric against other websites. So if your competitors have high domain authority than yours, they’ll likely rank higher in search engines.
Google is regularly reviewing and changing its search results. It considers so many factors in determining the ranking of a specific domain. Backlinks are vital to this process. If your links are posted on different high authority websites related to your industry, it means that you get the vote of confidence from other webmasters. This is important for your own ranking as Google and other search engines will know that you have quality content since you have acquired links from authoritative sites.
Because of this, your web pages will then show up at the tops of search engine results which will call the attention of the audience that your brand can be trusted. This will then bring lost of clicks and increase your conversion rates. All of these work together in building your domain authority.
Backlinks boost more traffic to your website
Naturally, search engines, especially Google, don’t trust a website that doesn’t get traffic. As a result, it would sit in a lower ranking in search results. But a website with lots of traffic? It undoubtedly offers some value, correct? No matter where the link comes from, whether it’s from a social media post, link placement, sponsored post or directory listing, once a user clicks a backlink and lands on your site, it helps in boosting your traffic.
Any link that will point to your own domain will bring traffic, thus bringing potential customers. Now, if these visitors see great and quality content, the tendency is it will lead to conversion. So for you to reach the full potential of the link you’ve earned, you must provide captivating reasons for your visitors to stay on your website and soon fall in love with your brand.
When you implement your strategy to get backlinks, your goal is to get these links from relevant and high-quality websites. A website with a Domain Authority of 40+ is ideal because it means that they have wide and established audience. You also have a better chance of increasing the traffic of your own website if backlinks come from high-quality sites.
They help build your reputation online
Search engines are not human, so they can never really capture the essence or intent of a content that is being shared. This is why backlinks are needed. If webmasters find your content valuable and refer it to their audience, it means that your website can be trusted.
Backlinks can be a tool for building your reputation online. For online users, the more a website is referred to them, the more they’ll become interested. As a result, because of social validation, they’ll eventually click on that link especially if backlinks come from renowned websites. It means that your contents are decent, and your website is credible and legit.
Aside from the rise in your online reputation, you’ll also notice a rise in your brand awareness. Your brand will rise above the smoke and will create a buzz in your industry because of the referrals given from trusted and reliable websites. Because of this, you’ll come out as top the same as those sites with high authority.
Conclusion
From the perspective of SEO, a backlink confirms the popularity of a site. Every time a website links to your pages, it means that they find your content credible and worth sharing. When search engines found a website with lots of links pointing to it and came from authority sites, they’ll conclude that the website shares valuable information and is worthy of being rewarded with high ranking. Naturally, search engines cannot really measure the quality of every website. So to determine the overall value of one website, they rely on the number of backlinks pointing to the site and the authority of those sites pointing to it.
