What are Backlinks in SEO? Definition, Importance & Types

Last year, a small website doubled its traffic within six months. The owner did not redesign the site. She did not increase her posting frequency. She focused on earning high-quality backlinks from relevant websites.

That brings us to an important question: what are backlinks? Backlinks are links from other websites that lead to your site. They help search engines measure trust and credibility. When reliable sites link to you, your rankings improve and your traffic grows.

Let us cover all in detail.

What are Backlinks?

Backlinks, also known as inbound links or incoming links, are links from one website to another. They are a signal to search engines that the linking website trusts and endorses the linked-to website. Backlinks are important for SEO because they’re seen as a signal of quality and authority. The more backlinks a website has, the higher it’s likely to rank in search results.

Let me clarify this concept with an example:

Imagine you’re a new restaurant in town. You want to get people to come to your restaurant, so you put up flyers all over town. You also ask your friends and family to tell their friends and family about your restaurant.

In the world of SEO, the flyers you put up all over town are like backlinks from other websites. And the word-of-mouth marketing you’re doing is like backlinks from your friends and family.

The more backlinks you have, the more people are likely to know about your restaurant. And the more people who know about your restaurant, the more people are likely to come.

The same is true for websites. The more backlinks you have, the more popular and authoritative your website is considered to be. And the more popular and authoritative your website is, the higher it’s likely to rank in search results.

Of course, not all backlinks are created equal. 

A backlink from a high-quality website is more valuable than a backlink from a low-quality website. That’s why it’s important to focus on getting backlinks from other reputable websites in your industry.

Here, you guys do not need to be worried, because in the next section, I am going to guide you on how you guys can create a high-quality backlink for your website.

Why are Backlinks Important?

Backlinks are the most important factor in ranking for search engines. Other websites trust and recognize them, and search engines use them to determine whether your site is a good source of information.

When a website connects to yours, it is essentially suggesting that your content is excellent enough to be suggested to the viewers of its own site. This is a strong recommendation, and it is one of the key reasons why backlinks are so crucial for site ranking.

Backlinks can assist you not just in ranking higher in search results, but also in:

• Drive more traffic to your website
• Increase your brand awareness
• Generate more leads and sales

Overall, backlinks are essential for any website that wants to succeed online.

What’s Backlink Authority & How Is It Determined?

The backlink authority of a website indicates the quality and relevance of its backlinks. Determining its ranking in search engine results pages (SERPs) is heavily reliant on this factor.

Google uses a variety of factors to determine backlink authority, including:

• The number of backlinks: A website with more backlinks is deemed more authoritative. Be aware that not all backlinks are equal. A high-quality, relevant backlink is worth more than a low-quality, irrelevant one.
• The quality of the linking websites: The authority of a website’s backlinks depends on its linked websites. High-authority backlinks are more important than low-authority ones.
• The anchor text of the backlinks: The anchor text of a backlink is the text that is used to link to a website. Google employs anchor text to determine link context and website relevance. Backlinks with relevant anchor text are more valuable than generic ones.

Here is an example for clearance:

Website A:

10 backlinks from high-quality, relevant websites

Website B:

100 backlinks from low-quality, irrelevant websites

Which website has higher backlink authority?

• Website A, because it has backlinks from fewer but higher-quality websites.

I think now you get the point! Let’s move on.

Types of Backlinks

Are there different types of backlinks? Yes, there are different types of backlinks, and each one plays a different role in SEO. Some help your rankings directly, while others support traffic, branding, or visibility. Below, I explain each type:

1. Dofollow Backlinks

Dofollow backlinks are the standard type of links. They tell search engines to follow the link and pass authority to the linked website. These links directly help improve rankings. Most SEO experts focus on earning high quality dofollow links because they pass link value.

• Pass authority from one site to another
• Directly impact keyword rankings
• Best when earned from trusted websites

2. Nofollow Backlinks

Nofollow backlinks tell search engines not to pass authority to the linked website. They use a special attribute that blocks link value transfer. These links do not directly boost rankings, but they still drive traffic and build brand trust. A natural backlink profile always includes some nofollow links.

• Do not pass SEO authority
• Often used in comments and ads
• Still useful for traffic and visibility

3. Sponsored Backlinks

Sponsored backlinks are paid links. Website owners add them when someone pays for placement. Search engines require these links to carry a sponsored tag. If you misuse them, you risk penalties.

• Used in paid promotions

Focus on depth, clarity, and usefulness instead of writing short general articles. Search engines reward content that provides complete answers. If your content stands out, backlinks follow without begging for them.

• Publish original research or case studies
• Add real examples and step-by-step solutions
• Update old posts with fresh data

2. Do Manual Outreach

Show them how your content adds value to their readers. Keep your message short and respectful. Strong outreach builds real backlink opportunities.

• Mention their recent article in your email
• Suggest a specific place for your link
• Follow up once if they do not reply

3. Build Long-Term Relationships

Link building works better when you build relationships first. Connect with bloggers and editors in your niche through comments and social media. Support their work before asking for anything. Trust increases the chances of earning natural links. Relationships create ongoing link opportunities.

• Share their content regularly
• Offer help without asking for links
• Stay active in industry discussions

4. Guest Post on Niche Websites

Guest posting allows you to publish content on other relevant websites. In return, you earn a backlink inside the article or author bio. Choose websites related to your industry and audience. Avoid spam blogs that exist only for links. High-quality guest posts build authority and traffic.

• Pitch unique topic ideas
• Follow the website guidelines strictly
• Add value instead of self promotion

5. Create Visual Content

• Scan resource pages in your niche
• Offer better content than the broken page
• Keep your outreach helpful, not pushy

7. Claim Unlinked Brand Mentions

Many websites mention your brand without linking to it. You can contact them and request a backlink politely. Since they already know your brand, success rates are higher. This method is easier than cold outreach. It turns simple mentions into SEO value.

• Set alerts for your brand name
• Reach out within a few days
• Thank them for the mention first

8. Reclaim Lost Backlinks

Sometimes backlinks disappear because pages get removed or URLs change. You should monitor your backlink profile regularly. If you find lost links, contact the website owner to restore them. You can also fix internal errors on your own site. This protects your SEO authority.

• Check lost links monthly
• Fix broken internal pages
• Use proper 301 redirects

9. Create Linkable Resources

Linkable resources attract backlinks naturally because they provide strong value. These include tools, templates, detailed guides, and research reports.

• Create free downloadable templates
• Publish industry statistics
• Build simple free tools

• Keep answers clear and short
• Track published features

• Choose niche specific directories

• Inform bloggers politely
• Avoid automated tools
