How to Find Lower-Quality Content Being Excluded From Indexing

Glenn Gabe published research on using Bing's Sitemap Index Coverage Report to identify content quality issues that search engines are detecting but not explicitly surfacing. The methodology provides a way to find content that Bing has evaluated and chosen not to index, potentially indicating quality problems that affect Google as well.

Bing as a Quality Indicator

While Google's Search Console provides limited insight into why pages aren't indexed, Bing's Webmaster Tools offers more granular data on indexing decisions. Pages that Bing specifically excludes from indexing despite being submitted via sitemap often have quality issues. Since both search engines evaluate similar quality signals, Bing's decisions can predict Google's assessments.

Methodology for Analysis

The research outlines a process for comparing sitemap submissions against Bing's indexed pages. Pages present in sitemaps but absent from Bing's index warrant investigation for thin content, duplicate content, or other quality issues. This analysis can identify problematic content at scale that manual review might miss.

Common Quality Issues Found

Content flagged through this method often exhibited thin content with minimal unique value, near-duplicate pages with insufficient differentiation, template-heavy pages with little substantive content, or outdated content that no longer serves user needs. Addressing these issues through content improvement or removal can improve overall site quality signals.

Practical Application

For large sites with thousands of pages, this methodology provides a scalable approach to content quality auditing. By focusing improvement efforts on pages that search engines have already evaluated negatively, teams can prioritize the most impactful content updates rather than reviewing every page manually.
