What Are Backlinks? Definition, Examples, and Why They Matter for SEO

What Are Backlinks?

A backlink is a link from one website to another.
When another website links to yours, Google sees it as a vote of confidence — a signal that your content is trustworthy and valuable.

In simple terms:

A backlink is like a recommendation from one website to another.

For example:

• If a Rotterdam business directory links to your web agency profile, that’s a backlink.
• If a local blog about digital marketing references your case study and links to it — that’s also a backlink.

The more relevant and high-quality backlinks you have, the higher your website can rank in Google.

Why Backlinks Are Important for SEO

Backlinks remain one of the strongest ranking factors in Google’s algorithm.
They help search engines understand:

• How authoritative your website is
• What your website is about
• How trustworthy your business appears online

Think of backlinks as digital reputation points — the more respected websites mention you, the higher your authority.

For example:

• A backlink from Rotterdam.nl or Sprout.nl carries far more value than one from an unknown blog.
• Quality > Quantity. Ten strong backlinks from relevant websites are better than 100 spammy links.

Types of Backlinks (with Examples)

1. Editorial backlinks
   Example: a journalist links to your insights in an article about web design in Rotterdam.
2. Guest post backlinks
   Example: you write a blog post for another marketing site and include a link to your portfolio.
3. Business directory backlinks
   Example: your company listed on a trusted directory like Drimble or De Telefoongids.
4. Local backlinks
   Example: a local Rotterdam chamber of commerce site linking to your business page.
5. Nofollow backlinks
   These don’t pass SEO value directly but still build visibility and trust.

Example of a Backlink in Practice

If a Rotterdam café mentions your web agency and links to your site in their “website made by” footer, that’s a contextual backlink — and a strong local signal for SEO.

That single link tells Google that your agency is active in the Rotterdam region, helping your local SEO performance.

How to Build Quality Backlinks (Without Spamming)

1. Create valuable, link-worthy content (case studies, guides, data).
2. Reach out to local businesses for collaborations.
3. Publish guest blogs on related sites.
4. Get listed in trustworthy directories.
5. Promote content on social media and industry forums.
