What Are Backlinks?

Backlinks are links from one website to another website. In SEO, a backlink is created when another website links to a page on your website.

For example, if a digital marketing website publishes an article and includes a link to your website, that link is a backlink for your website.

Simple Example

Suppose:

Website A: GrowthHive.com
Website B: Another marketing website

If Website B writes:

Learn more about digital marketing strategies at GrowthHive.

and “GrowthHive” contains a link to your website, then GrowthHive has received a backlink from Website B.

Why Are Backlinks Important?

Backlinks are an important part of SEO because search engines can use links as signals for discovering pages and understanding relationships between websites.

Historically, links have also been used as a signal related to the authority or prominence of pages. However, not all backlinks have equal value, and simply having a large number of backlinks does not guarantee higher rankings.

A strong backlink profile generally focuses on relevance, quality, trust, and natural acquisition rather than quantity alone.

How Do Backlinks Work?

Imagine several websites recommending the same resource.

For example:

Website A links to your SEO guide.
Website B references your research.
Website C recommends your tutorial.

These links create connections between their websites and yours.

Search engines can discover your page through links and use various signals to understand the relationship and importance of pages.

However, search engines evaluate links using many factors, so you should not think of a backlink as a simple “vote” that automatically increases rankings.

Example of a Backlink

Suppose you have an article:

“Complete Guide to Keyword Research”

Another website publishes an article about SEO and writes:

You can learn more about keyword research in this detailed guide.

If “keyword research” links to your article, you have received a backlink.

The clickable text is called anchor text.

What Is Anchor Text?

Anchor text is the visible, clickable text of a hyperlink.

Example:

Learn more about technical SEO.

Here, “technical SEO” is the anchor text.

Common types of anchor text include:

1. Exact-Match Anchor Text

The anchor text exactly matches the target keyword.

Example:

Keyword Research

2. Partial-Match Anchor Text

The anchor contains part of the target topic.

Example:

Complete keyword research guide

3. Branded Anchor Text

The brand name is used.

Example:

GrowthHive

4. Naked URL

The actual URL is used as the anchor.

Example:

https://example.com

5. Generic Anchor Text

Generic phrases are used.

Examples:

Click here
Read more
Learn more
Visit website

A natural backlink profile can contain different types of anchor text rather than relying excessively on exact-match keywords.

Types of Backlinks

1. Editorial Backlinks

An editorial backlink occurs when another website naturally references your content because it finds the information useful.

For example, a marketing publication might link to your original research when discussing SEO trends.

These links can be valuable because they are contextually relevant and naturally placed.

2. Guest Post Backlinks

A guest post is an article written for another website.

For example, you write an article about:

“SEO Strategies for Small Businesses”

for another marketing website, and the publication allows a relevant link to your website.

Guest posting can be legitimate when the primary purpose is providing useful content to the audience. However, creating large numbers of low-quality guest posts primarily for manipulating rankings can violate search-engine spam policies.

3. Business Directory Backlinks

Business directories can contain information about a company, including its website.

Examples may include:

Business directories
Local directories
Industry directories
Professional associations

These can be useful for local visibility when the directory is legitimate, relevant, and provides genuine value.

4. Social Media Links

Links can also appear on social platforms such as:

Facebook
LinkedIn
Pinterest
X
YouTube

These links can help people discover your website and generate referral traffic.

However, social links should not be treated as equivalent to editorial backlinks from authoritative websites.

5. Resource Page Backlinks

Some websites maintain resource pages that link to useful external websites.

For example:

Best SEO Resources

A website may include your comprehensive SEO guide in its resource list.

6. Broken Link Building

Broken link building involves finding a relevant broken external link and suggesting your useful content as a replacement.

For example:

You find a website with a broken link.
The broken link previously pointed to an SEO guide.
You have a useful guide covering the same subject.
You contact the website owner and suggest your resource.

The website owner can decide whether to replace the broken link.

Dofollow vs Nofollow Links

Links can include attributes that provide search engines with additional instructions.

Dofollow Links

“Dofollow” is commonly used in SEO to describe ordinary links that do not contain a nofollow instruction.

For example:


<a href="https://example.com">Example Website</a>

There is no nofollow attribute here.

Nofollow Links

A link can use:


<a href="https://example.com" rel="nofollow">Example Website</a>

The nofollow attribute tells search engines not to associate the link in the normal way.

However, nofollow is not the only link-related attribute. Search engines also recognize:

rel="sponsored" — for paid or sponsored links
rel="ugc" — for user-generated content
rel="nofollow" — when the site owner does not want the normal association

These attributes help search engines understand the nature of a link.

What Makes a Good Backlink?

A useful backlink generally has several positive characteristics.

1. Relevance

A link from a website related to your topic can be more meaningful than a completely unrelated link.

For example, a backlink from a marketing website to a digital marketing article is contextually relevant.

2. Quality of the Linking Website

The overall quality and credibility of the website providing the link matter.

A link from an established, trustworthy publication is generally more valuable than a link from a low-quality website created primarily for links.

3. Context

Where and how the link appears matters.

A naturally placed link within a useful article can provide more context than a random link placed on an unrelated page.

4. Natural Anchor Text

Anchor text should make sense for the surrounding content.

Avoid trying to manipulate rankings by repeatedly using exactly the same keyword-rich anchor text.

5. Genuine Value

The strongest approach is to create content that other websites genuinely want to reference.

High-Quality vs Low-Quality Backlinks

High-Quality Backlink	Low-Quality Backlink
Relevant website	Unrelated website
Genuine editorial mention	Artificial placement
Useful surrounding content	Low-quality content
Natural anchor text	Excessive keyword-rich anchor
Trusted website	Spammy website
Provides referral value	Created only to manipulate rankings

The goal should be to earn relevant, natural, useful links, not simply to increase the backlink count.

What Is a Backlink Profile?

A backlink profile is the overall collection of links pointing to your website.

It can include information such as:

Number of referring domains
Number of backlinks
Linking pages
Anchor text
Link attributes
Relevance of linking websites
Quality of referring domains
Growth of links over time

For example:

Website A

50 referring domains
120 backlinks
Mostly relevant websites
Natural anchor-text distribution

This gives you an overall picture of the site's link profile.

Referring Domains vs Backlinks

These two terms are often confused.

Backlinks

The total number of links pointing to your website.

Referring Domains

The number of unique websites that provide those links.

For example:

Website A links to you 5 times.
Website B links to you 3 times.
Website C links to you 2 times.

You have:

10 backlinks

but only:

3 referring domains

So, referring domains and total backlinks measure different things.

Internal Links vs Backlinks

Internal Links

Links between pages on the same website.

Example:

Your homepage → Your SEO blog post

This is an internal link.

Backlinks

Links from another website to your website.

Example:

Another company's website → Your SEO blog post

This is a backlink.

Both are important parts of SEO, but they serve different purposes.

How to Get Backlinks

There are several legitimate ways to earn backlinks.

1. Create High-Quality Content

Create content that people naturally want to reference.

Examples:

Original research
Statistics
Comprehensive guides
Case studies
Original surveys
Useful tools
Industry reports
Detailed tutorials

2. Create Link-Worthy Resources

Instead of creating content only for keywords, create resources that solve a specific problem.

For example:

Complete SEO Checklist for Small Businesses

Other websites may reference a useful checklist when creating their own content.

3. Digital PR

If you have something genuinely newsworthy, digital PR can help get your brand or research mentioned by relevant publications.

4. Guest Contributions

Contribute genuinely useful articles to relevant publications where appropriate.

5. Build Relationships

Networking with:

Bloggers
Journalists
Industry experts
Businesses
Publishers
Content creators

can create opportunities for legitimate references and collaborations.

6. Promote Your Content

Share useful content through:

Social media
Communities
Email newsletters
Industry networks

Promotion does not guarantee backlinks, but it can increase the number of people who discover your content.

What Is Link Building?

Link building is the process of acquiring backlinks from other websites.

For example:

Create useful content → Promote it → Relevant websites discover it → Some websites link to it

This is a simplified example of a natural link-building process.

Link building should focus on creating genuine value rather than manipulating search rankings.

Backlinks and Domain Authority

You may hear SEO professionals talk about metrics such as:

Domain Authority (DA)
Domain Rating (DR)
Authority Score

These are third-party SEO metrics, not Google's official ranking scores.

They can be useful for comparing websites within an SEO tool, but they should not be treated as direct measurements of Google's ranking algorithm.

A website with a high third-party authority score is not automatically guaranteed to pass ranking value through every link.

Common Backlink Mistakes

1. Buying Large Numbers of Links

Purchasing links specifically to manipulate search rankings can violate search-engine guidelines.

2. Using Link Farms

Link farms are networks created primarily to generate links rather than provide genuine value.

3. Excessive Exact-Match Anchor Text

Using the same keyword-rich anchor repeatedly can create an unnatural link profile.

4. Getting Links From Irrelevant Websites

A large number of unrelated links is generally less useful than relevant references.

5. Focusing Only on Quantity

100 poor-quality links do not necessarily provide more SEO value than a smaller number of relevant, genuine references.

6. Using Automated Link-Building Systems

Automated systems that generate links at scale can create spam and may result in search-engine penalties or algorithmic devaluation.

How to Check Backlinks

You can analyze backlinks using tools such as:

Google Search Console
Ahrefs
Semrush
Moz
Ubersuggest

These tools can help you examine:

Backlinks
Referring domains
Anchor text
Linking pages
Lost links
New links
Competitor backlinks

Google Search Console is particularly useful for viewing Google's link data for your own verified website.

Backlinks for Local SEO

Backlinks can also be useful for local businesses.

For example, a local business may receive links from:

Local news websites
Local business directories
Chamber of commerce websites
Local organizations
Industry associations
Community websites
Local blogs

Relevance and legitimacy are important. A relevant local mention can be more meaningful than a large number of unrelated directory links.

Backlinks vs Citations

These are related but different concepts.

Backlink:
A clickable link from another website to your website.

Citation:
A mention of your business information, such as:

Business name
Address
Phone number

A local citation may or may not include a clickable backlink.

Backlink Strategy for a New Website

For a new website, a practical approach is:

Step 1: Create useful, original content.

Step 2: Build topical authority with high-quality articles.

Step 3: Optimize internal linking.

Step 4: Promote useful content.

Step 5: Build relationships with relevant websites.

Step 6: Look for legitimate guest contribution and resource opportunities.

Step 7: Monitor your backlink profile.

Step 8: Focus on quality and relevance rather than chasing a specific backlink count.

Example of a Backlink Strategy for a Digital Marketing Website

Suppose you run a digital marketing website.

You publish:

“Complete Guide to Technical SEO”

You could promote it to:

SEO blogs
Marketing publications
Business websites
Educational resources
Digital marketing communities

If relevant websites find the guide useful and reference it naturally, you can earn backlinks.

You could also publish original research such as:

“SEO Trends Among Small Businesses in 2026”

Original data is often more link-worthy because other websites can cite your findings.

Conclusion

Backlinks are links from external websites to your website and are an important part of SEO. They can help search engines discover content and can contribute to how pages and sites are understood and evaluated.

However, successful SEO is not about collecting as many backlinks as possible. A better approach is to earn relevant, natural, trustworthy links by creating content that people genuinely find useful.

A strong backlink strategy should focus on:

Quality + Relevance + Context + Natural Links + Useful Content

When combined with technical SEO, on-page SEO, keyword research, internal linking, and high-quality content, backlinks can become an important component of a long-term SEO strategy.
