Types of Backlinks That Influence Website Authority

1. Editorial Backlinks

Editorial backlinks are considered the most authoritative and valuable type of backlink in SEO. These links are earned naturally when other websites reference your content within their articles because they find it genuinely informative, trustworthy, or worth citing. There is no exchange, payment, or outreach request involved, which is why search engines treat editorial backlinks as strong indicators of content quality and relevance.

These backlinks typically appear within the main body of high-quality content and come from websites that are already trusted by search engines. Because they are organic and merit-based, editorial backlinks carry significant ranking power and contribute strongly to long-term SEO growth.

Key characteristics of editorial backlinks:

• Earned naturally without requesting or paying for links
• Usually placed within contextual, relevant content
• Come from authoritative and niche-relevant websites
• Provide strong ranking, trust, and credibility benefits

When done ethically, guest posting is an effective way to build authority, visibility, and referral traffic.

However, the SEO value of guest post backlinks depends heavily on the quality of the website and content. Guest posting on low-quality or spammy sites purely for link building can negatively impact SEO, while publishing on reputable platforms strengthens brand authority and topical relevance.

• Highly relevant to the linked content
• Trusted by search engines due to user-focused intent
