Why Backlinks are Important in SEO?
Search engines like Google use backlinks as one of the top three ranking factors. Its help:
- Drive referral traffic
- Increase domain authority
- Improve search rankings
- Build trust with users and search engines
In the eyes of Google, quality links = credibility.
Types of Backlinks
DoFollow vs NoFollow Links
- DoFollow links tell search engines to follow the link and pass link juice.
- NoFollow links include a tag that says “Don’t follow me,” so they don’t directly influence rankings.
Even though NoFollow links don’t pass authority, they can drive traffic and brand awareness.
Natural vs Unnatural Backlinks
- Natural links happen when others link to your site naturally because of quality content.
- Unnatural links are often bought, spammy, or forced—and can get you penalized by Google.
Editorial Links
These are earned naturally when other sites reference your content. Google loves these the most.
Guest Post Links
Guest posting on reputable sites and linking back to your own content is a great way to earn backlinks—as long as it’s not spammy.
Directory and Social Profile Links
Submitting your website to trusted directories (like Google Business Profile) or adding it to social bios helps in early-stage SEO.
How Backlinks Impact Search Engine Rankings
Link Authority (DA & PA)
- Domain Authority (DA) measures the overall strength of a website.
- Page Authority (PA) focuses on the strength of a specific page.
The higher the DA/PA of the site linking to you, the better your SEO juice.
Relevance of the Linking Domain
A backlink from a relevant industry site is worth more than one from an unrelated site. Google evaluates context.

Links placed within content (contextual links) are more powerful than ones stuck in the footer or sidebar.
