Backlinks, also known as inbound or incoming links, are links from one site to another. Backlinks are links from other sites that send traffic to a specific page on your site.
But what is the importance of backlinks in SEO, anyway? Do they really matter when it comes to sending Google Search traffic to sites?
The short answer is yes, in 2025 and for many years now. Backlinks are a key ranking factor in search engine optimization (SEO) because they’re a signal of credibility, trust and authority.
When a site links to your content, it’s essentially vouching for your site, telling search engines your content is valuable and relevant.
Our LinkLadder resource goes into how to get backlinks that matter and the importance of finding the right backlinks for your site or sites.
Why Are Backlinks Important for SEO?
Search engines like Google use backlinks as a way to measure a site’s authority and relevance. The more high quality backlinks a page has, the higher it will rank in search engine results pages (SERPs).
Here are some key reasons why backlinks are important for SEO:
1. Better Search Engine Rankings
Google’s algorithm considers backlinks as “votes of confidence”. Search engines evaluate these backlinks to determine a site’s credibility and relevance. A site with a lot of quality backlinks will rank higher than one without. But it’s not just about quantity—quality matters.
A few backlinks from authoritative sites can be more effective in terms of link building than many links from low quality sources and spammy web pages or sites built just to sell guest posts.
2. Increased Website Authority
Authority is a ranking factor. Understanding the concept of domain authority is key to effective link building. Sites with strong backlink profiles are perceived as industry leaders. Google assigns a metric called Domain Authority (DA) or Domain Rating (DR) which is influenced by the number and quality of backlinks pointing to a site.
3. Better Discoverability and Indexing
Search engine crawlers use backlinks to find new content on the web. External links from reputable sources can increase your site’s discoverability and indexing. If you’re frequently linked from other reputable sites, you’ll get indexed faster and ranked better in search results.
4. Referral Traffic Boost
Backlinks don’t just help with rankings; they also drive traffic. Backlinks from other sites establish your credibility to both search engines and visitors.
When users click on links from other sites that direct them to yours, it can lead to increased engagement and conversions.
5. Builds Trust and Credibility
If a well-known site links to your content, visitors will trust your brand. High quality backlinks from quality sites can increase your credibility. High quality backlinks from authoritative sites can increase your credibility and make you a players in your niche.
Types of Backlinks
Not all backlinks are created equal. A well thought out plan is key to tailoring your link building strategy to your specific needs and goals. Understanding the different types of backlinks will help you focus on getting high value links that boost your SEO efforts.

Dofollow links pass “link juice”, meaning they transfer authority from the linking site to the linked site. These are the most valuable backlinks for SEO purposes.
Note that internal links (inbound links from your site) are also important and are considered as a factor in Google rankings.
2. Nofollow Backlinks
Nofollow links have an attribute that tells search engines not to pass link juice. Experts recommend using nofollow links strategically to drive traffic and add credibility. While they may not directly impact rankings, they can still drive traffic and add credibility.
3. Editorial Backlinks

4. Guest Post Backlinks
Guest posting on other reputable blogs allows you to include backlinks to your site, often in the author bio or within the content itself. Leverage existing business relationships with a partner to enhance your guest posting opportunities.
5. Directory Backlinks
These come from online directories and business listings. Submit to reputable directories to get dozens of valuable backlinks. While not as powerful as editorial links, they can still contribute to a strong backlink profile if from reputable sources.
