Backlinks are links from other websites that direct users to a page on your website. They are also known as inbound links because they bring visitors from external sites to yours. The number and quality of backlinks you have can improve your website’s ranking on search engines like Google and Bing.
Backlinks show how popular your website is among users. Managing and tracking backlinks is a key part of search engine optimization (SEO) and helps improve your website’s ranking.
To boost organic traffic and attract search engines, you need to focus on both on-page and off-page SEO. On-page SEO involves creating content that helps search engines and users understand your website. Off-page SEO, on the other hand, proves to search engines that your content is valuable to others. One of the strongest signals of this value is a backlink.
What’s the difference between a link & a backlink?
A link connects one web page to another. It helps users navigate a website or find more information. Links can be of two types:
- Internal links – These connect pages within the same website. They help users explore different sections of the site easily.
- External links – These lead to pages on different websites. They can serve various purposes, such as:
-
- Giving more context
- Supporting a statement
- Citing a source
- Recommending something
- Adding credibility
Every link has a direction. If a webpage links to another site, it’s an outgoing link for the first site but an incoming link for the second site. That incoming link is called a backlink for the site receiving it.
Search engines see backlinks as valuable and give credit to the webpage they point to. They treat backlinks as intentional, assuming that the linking site has reviewed and approved the content of the target page.
Backlinks show search engines that your content is valuable. They are one of the strongest factors that affect rankings. A website’s success in getting organic search traffic often depends on the quality and number of backlinks it has.
What is Backlink Authority & How is it Measured?
Google became the top search engine because it understood the importance of backlinks for SEO. When it launched in 1998, it introduced a new way to rank web pages based on the number of links pointing to them. The idea was simple, the more links a page has, the higher it ranks in search results.
This ranking system, called PageRank, was named after Google co-founder Larry Page. It doesn’t just count how many links a webpage gets—it also evaluates the quality and authority of those links.
Not all backlinks have the same value. Suppose one of your web pages gets backlinks from two different websites:
- Page A has 200 backlinks
- Page B has 20 backlinks
If both pages cover the same topic, Page A is likely to rank higher because it has more backlinks, making it more authoritative.
Now, when these two pages link to your website, the backlink from Page A carries more weight than the one from Page B because it comes from a stronger source.
Google’s PageRank system measures a webpage’s authority by analyzing both the number and quality of its backlinks.
Understanding a Simple Link Network
PageRank is an iterative algorithm, meaning it runs multiple times, adjusting calculations until the results stabilize. This happens because the authority of each webpage depends on the others in the network.
Let’s look at a simple network of four pages:
- Page A links to Page B and Page C and gets a backlink from Page B.
- Page B links to Page A and Page D and gets backlinks from Page A and Page C.
- Page C links to Page B and Page D and gets a backlink from Page A.
- Page D doesn’t link out but gets backlinks from Page B and Page C.
To calculate Page D’s authority, we first need to determine the authority of Page B and Page C. However, Page B’s authority depends on Page A and Page C, and Page A’s authority is influenced by Page B. This cycle is why the algorithm needs multiple rounds of calculations before reaching a final ranking.
Even a small link network can quickly become complex. The only way to get accurate results is to keep running the calculations multiple times until the rankings stabilize. While the math itself isn’t too difficult, the real challenge lies in the sheer size of the dataset—trillions of links across the internet—which requires massive computational power to process.
What is Domain Authority?
Domain authority refers to the strength of a website based on its internal link structure and backlinks from other sites. Just like external links, internal links within a website also pass authority from one page to another.
Websites with strong reputations, like CNN, have higher domain authority compared to smaller, lesser-known sites. A backlink from a well-established site carries more weight than one from a small local business. The more trusted and authoritative a website is, the more valuable its links become.
If your homepage gets a backlink from a local news website, it gains authority. Since your homepage also links to other pages on your site, some of that authority is passed down to those pages. In turn, those pages share authority with the pages they link to.
This means that backlinks from other websites don’t just help one page—they gradually spread authority throughout your entire site. Pages that are closer to the top of the site’s structure receive more of this authority.
This is why big brands often rank higher for certain search terms. Their strong domain authority, combined with effective internal linking, helps even their newly published pages rank well in search results.
Quantity & Quality – Both Matter in Backlinks
Figuring out the exact value of a backlink is complicated but understanding PageRank gives some simple guidelines:
- Aim to get as many backlinks as possible.
- Backlinks from trusted, high-authority websites are more valuable.
- You can often judge a website’s authority by looking at its reputation and content.
- More backlinks help boost the ranking of your entire site.
In short, both the number and quality of backlinks play a crucial role in improving your website’s authority and search rankings.
Benefits of Backlinks
Backlinks are a key part of SEO because search engines use them to measure a page’s authority and relevance. The more high-quality backlinks a page has, the more important it appears to search engines.
However, not all backlinks hold the same weight. Search engines focus more on the quality of the site linking to you rather than just counting the number of backlinks. A few strong backlinks from trusted websites are far more valuable than many low-quality links.
How Backlinks Help Your Website
Backlinks help improve your search rankings because they signal to search engines that your content is valuable. The more high-quality backlinks you have, the better your chances of ranking higher.
Beyond rankings, backlinks also help more people discover your brand. When popular websites link to you, they send visitors who are already interested in your content. This increases referral traffic and brings in potential customers, guiding them into your marketing funnel.
How to Assess Backlink Relevance
Now that you understand what backlinks are, let’s explore how search engines determine their relevance.
Besides measuring a backlink’s authority, Google also checks if it is relevant to your content. It looks at factors like:
- Does the linked page relate to the topic of your website?
- Is the content on the linking page relevant to your industry or niche?
- Does the website itself focus on similar subjects?
A backlink is more valuable when it comes from a relevant source, as it signals to search engines that your content is trustworthy and useful within that topic.
Example of Backlink Relevance
Let’s say you run a website that sells musical equipment and one of your pages sells guitar picks. This page gets a backlink from three different websites.
Link 1
- The website is well-known in the music industry.
- The page containing the link is about guitars.
- The anchor text says “Read more here.”
Even though the anchor text doesn’t clearly indicate relevance, the website and page content do. This makes it a valuable and relevant backlink for your site.
Link 2
- The website is well-known in the automotive industry.
- The page linking to your site is about refueling.
- The anchor text says “Gasoline vs. diesel.”
In this case, the link has no relevance to your musical equipment website. Even though the source is authoritative, the topic has nothing to do with your content. Because of this, Google might not consider the link valuable or may ignore it altogether.
Link 3
- The website is not very well-known in the guitar equipment industry.
- The page linking to your site is about guitar picks.
- The anchor text says “Best guitar picks.”
Even though this website isn’t highly authoritative, the content, page topic and anchor text are all relevant to your site. This makes it a valuable backlink because it sends clear relevance signals to search engines.
You might receive backlinks from many different websites including some that seem unrelated to your content. These links usually don’t help or harm your site. However, the most beneficial backlinks come from highly relevant sources, as they send a stronger signal to Google that your website is a good fit for a specific topic.
After optimizing your website’s content, building backlinks is one of the best ways to boost your search rankings.
However, getting backlinks isn’t easy. You need to convince other website owners that adding a link to your page will improve their content and provide value to their visitors.
Reaching out to random people and asking for backlinks isn’t a good strategy. Instead, it’s better to follow professional methods that increase your chances of getting quality backlinks.
How to Get Backlinks
Link Building
Link building is the process of actively getting backlinks to your website. It’s a specialized area of SEO that requires experience and strategy.
If you’re just starting out, focus on understanding the importance of backlinks and engaging in activities that naturally attract them. Since links are a core part of how the internet works, creating valuable content increases the chances of earning backlinks over time.
The real issue is the lack of effort—if you don’t take any steps to get backlinks, your chances of improving search rankings are very low.
Link building takes time and experimentation to find what works best for your website.
Ways to Get Backlinks
Backlinks are usually earned in two ways:
- Someone naturally finds your content and decides to link to it.
- You share your content with others and they choose to link to it.
Getting backlinks is similar to generating leads—you need to reach the right people with your content. The best method depends on your content type, potential link sources and how you get them to notice your site. Different strategies work for different websites, so testing and adapting is key.
Here are some sources that can help you earn quality backlinks:
- Suppliers & Retailers – If you have business relationships with suppliers or retailers, ask them to mention your website. Many companies have a partners or listings section, so make sure your site is included.
- Business Partnerships – If you have business partners, use the relationship to boost your visibility. You can:
- Provide guest content for their website.
- Collaborate on co-promotional activities like webinars.
- Gain exposure to their audience while earning valuable backlinks.
- Local Community – Getting involved in your community not only helps others but also promotes your business. You can:
- Sponsor local events.
- Organize meetups.
- Volunteer at schools or universities.
These activities can lead to mentions & backlinks from community websites.
- Testimonials – If you use a product or service and have a positive experience, share your story. Many companies feature customer testimonials or case studies on their websites. If your testimonial is published with a link to your site, it’s a win-win for both sides.
- Charities – Supporting charities can help your business gain goodwill and recognition. Many charities highlight companies that contribute to their cause.
While donating only for backlinks isn’t ethical, there’s nothing wrong with making the most of the charity work you or your team already do. If a charity features your business on their website, it can be a great way to gain visibility and earn a backlink.
- Niche Bloggers – Many industries have dedicated bloggers who create valuable content for their audience. Building relationships with these bloggers can help boost your online presence.
Since they already have an engaged audience, collaborating with them can be beneficial if your product or service aligns with their niche. You can:
-
- Offer to write a guest feature for their blog
- Send them samples to review
- Do an interview with them
- Invite them to write on your site as a guest author
Working with niche bloggers can help you reach a wider audience while also earning valuable backlinks.
- Press – Getting media coverage can be challenging but it’s worth the effort because journalists are always looking for interesting stories. If you have a unique or compelling story about your business or products, it might catch their attention. The best part? News spreads quickly. Once a story gets published, other media outlets might pick it up, expanding your reach even further. To improve your chances, learn basic PR skills—this will help you pitch your story effectively and understand what makes a newsworthy topic.
When using these strategies, never directly ask for a link. Instead, focus on getting mentioned or featured—the backlink should come naturally as part of the process.
The goal is to engage in activities that have the potential to generate backlinks. The best strategies are those that provide business value, even if a backlink isn’t guaranteed.
Frequently Asked Questions
What is an example of a backlink?
A backlink is when one website links to another using anchor text. For example, if a blog post includes a link to another website as a source, that’s a backlink. You can find backlinks all over the internet, especially on popular blogs that link to relevant content.
How Do Backlinks Improve SEO?
Backlinks help improve SEO by increasing your website’s authority which can lead to higher rankings in search engine results (SERPs). While getting more backlinks is a beneficial, quality matters more than quantity. A few links from trusted, high-authority websites are far more valuable than many low-quality links.
How Can I Get Backlinks from High-Authority Websites?
The best way to earn backlinks from high-authority websites is by creating high-quality content. These websites often cite reliable sources, so if you produce original and valuable content—such as blogs, infographics or videos—they are more likely to link to you.
Another strategy is to mention and link to authoritative sources in your own content. This increases the chances of getting noticed and potentially earning a backlink in return.
The Importance of Link Building
SEO relies on three key factors: keyword research, on-page optimization and backlinks. Focusing on just one without the others can limit your success. Among these, backlinks are one of the most important because they help improve search rankings, boost website visibility and drive traffic.
Beyond SEO, links also increase brand awareness by exposing your site to new audiences. That’s why link building should be a key part of your SEO strategy.
