Understanding Backlinks and Their SEO Impact

When another website links to yours, it passes what's known as "link equity." This endorsement helps search engines evaluate the relevance and credibility of your content.

Define Dofollow vs. Nofollow Backlinks

• Dofollow links: Pass full link equity to your site, boosting your authority

• Nofollow links: Include a tag that tells search engines not to pass link equity, but they still drive referral traffic and help diversify your link profile

High-DA Backlink Sites and Resource Page Link Building

Websites with high domain authority (DA) like established news outlets, industry publications, and popular blogs offer the most value. Resource pages—collections of external links curated by webmasters—are goldmines for targeted relevance and link quality.
