Backlink Quality Assessment

Overview

Backlink analysis evaluates incoming links by quality metrics (DA/DR, relevance, anchor text diversity, toxicity) to assess a site's off-page SEO strength. Quality assessment is heuristic-based using third-party metrics (Moz DA, Ahrefs DR) as PageRank proxies.

When to Use

Trigger conditions:

• Auditing a site's backlink profile for SEO health
• Identifying and disavowing toxic or spammy links
• Planning link building strategy based on competitor analysis

When NOT to use:

• When optimizing on-page content (use content SEO)
• When computing actual PageRank from raw link graphs (use PageRank algorithm)
