Backlinks in SEO: What They Are, Why They Matter & How to Build Them
If you’ve ever wondered why some websites rank higher than others in Google search, the answer often lies in backlinks. Backlinks are one of the top ranking factors in SEO and play a critical role in building a website’s authority, trust, and visibility.
At Small SEO Tool, we help businesses understand backlinks, analyze their link profiles, and build strategies to gain high-quality backlinks that boost search rankings.
What Are Backlinks in SEO?
A backlink (also known as an inbound link or incoming link) is a link from one website to another.
When Site A links to Site B, it’s like a “vote of confidence” telling search engines that Site B is trustworthy and valuable.
👉 The more high-quality backlinks your website earns, the higher your chances of ranking on Google.
Why Are Backlinks Important for SEO?
Google’s algorithm uses backlinks as a signal of authority. Websites with more credible backlinks tend to:
- Rank higher in search results
- Get more organic traffic
- Build brand credibility
- Improve domain authority (DA)

Example of a Backlink
Imagine you run a fitness blog.
- A health magazine writes an article: “10 Best Fitness Blogs to Follow in 2025” and links to your website.
✅ That’s a high-quality backlink because it comes from a relevant and authoritative site.
On the other hand:
- A spammy site links to your blog randomly.
❌ That’s a toxic backlink that could harm your rankings.
Types of Backlinks in SEO
Not all backlinks are equal. Here are the main types:
1. Do-Follow Backlinks
- Pass SEO value (link juice) to your site.
- Most valuable type of backlink.
2. No-Follow Backlinks
- Tell search engines not to transfer link authority.
- Still useful for traffic and visibility.
3. Editorial Backlinks
- Earned naturally when websites reference your content.
- Example: A news site citing your original research.
4. Guest Post Backlinks
- Links gained by writing content for another site in your niche.
5. Directory and Business Listings
- Local SEO backlinks from directories like Google Business Profile or Yelp.

Backlinks and Google Ranking Example

✅ Result: Website A ranks higher because quality outweighs quantity in Google’s eyes.
