Backlinks play a very critical role in search engine optimisation. They help search engines understand whether a website is trusted and valuable or not. If you are a beginner, you may find backlinks a bit confusing, but they are actually very simple to understand. Let’s understand what backlinks are and why they matter so much from an SEO perspective.

What Are Backlinks

A backlink is a link from one website to another website. Let's understand backlinks with an example. Suppose you own a website, and you want your website to look credible and trustworthy in the eyes of search engines. So, what you’ll do is you will put the link to your website on an external website. Even another website can add a link to your website on its own pages. This will be a backlink for you. Search engines see this as a signal that your content is helpful for users. 

Backlinks Explained in Simple Words

Backlinks are like recommendations. When a trustworthy website links to your website, it gives the signal to the search engines that your content is helpful. Search engines trust websites that receive links from other trusted websites. Many website owners think that all backlinks are equal, but that’s not true. Not all backlinks are equal. A link from a well-known website is more valuable than a link from a low-quality site. Quality matters more than quantity.

Why Backlinks Are Important for SEO

Backlinks signal search engines that a given website is a high-authority website, so they will rank it at the top of the search results. Websites with strong backlinks usually rank higher because search engines see them as more reliable.

Search engines discover new pages through backlinks. When a page is linked, it becomes easier for search engines to find and index it. In order to understand how many backlinks your website has and where they are coming from, you can use a free SEO audit tool. This will give you a clear picture of your backlink strength.

Types of Backlinks

There are different types of backlinks. 

1. Natural Backlinks

These links are used naturally by other websites, as they found your content useful.

Example:  A blog links to your article without you asking for it, as it found your article useful

2. Editorial Backlinks

These are the links that are added inside content by website owners or editors.
They are usually high quality and trusted.

Example: A news website links to your blog as a reference.

3. Guest Post Backlinks

When you write articles for other websites, you put your link in them.

Example: You write a blog or an article for another site and add your website link.

4. Directory Backlinks

These links come from online directories that list businesses or websites. If the directory is trusted, only then will these links be useful for your website. 

Example: Business listing websites provide links to your website.

5. Profile Backlinks

These are links that are added to user profiles on websites, forums or social platforms.

Example: Adding your website link to a profile bio.

6. Social Media Backlinks

These are the links that bring visitors from different social media platforms. These links will bring traffic and increase visibility of your website, but they are not very useful from an SEO perspective.

Example: Links from Facebook, Instagram, LinkedIn or Twitter.

7. Forum Backlinks

These links come from forum discussions where users share website links.

Example: Here, you will answer questions and add your website link.

8. Comment Backlinks

These links are added in blog comments. If you do not use it carefully, it will be considered as spam.

9. Nofollow Backlinks

These links tell search engines not to crawl the given link. When you put your link to a more trustworthy website, they do not want search engines to crawl your pages through back link as it can give you ranking advantages. However, you will get the traffic.

Example: A puts its website’s link on B’s website. B’s website is more trustworthy. So the audience of B’s website will go to A’s website, but the crawler of search engines will not crawl A’s website, so A will not get the advantage of ranking at the top of the search results. 

10. Dofollow Backlinks

Here, when you put your website’s link on a trustworthy website, the search engines can crawl your web page through your link. Thus, you will be receiving the traffic from the website and also get a good rank in search results. 

How Backlinks Improve Website Authority

Website authority refers to how trustworthy a website is. Backlinks play a very important role in building authority. When many trusted sites link to you, your authority will grow naturally. Higher authority gives you many advantages, as the majority of your pages on your website perform better in search results. This means more visibility and more traffic over time. You must check your backlink profile with a free SEO audit tool that helps you see how your website authority is growing and what are the areas you need to improve.

How to Get Quality Backlinks

Quality backlinks can come from good content only. When you create useful content, other websites are more likely to link to it. When you write interesting guides, blogs and useful resources, it will attract links. Always focus on quality rather than quantity. Avoid buying links or using spam methods. These can harm your website and reduce trust.

Monitoring and Managing Backlinks

Backlinks need to be regularly monitored. Websites change, and links can be removed or replaced. In order to check this, you need an SEO audit tool. It will provide regular reports on new backlinks that you have made and the lost ones, too. This will give you a deep understanding of trends, and this way you can plan future actions.

Final Thoughts
