Issue Category Breakdown
717K+ issues categorized by type (broken links, missing meta, redirect chains, duplicate content) with counts per domain.
What It Shows
The Issue Category Breakdown view slices the portfolio-wide issue count by issue type rather than by domain. This reveals which types of problems are most prevalent across the NKP client base.
Issue categories with counts:
- Broken internal links —
<a>tags pointing to 404 pages - Broken external links — outbound links returning errors
- Missing title tags — pages without a
<title>element - Missing meta descriptions — pages without
<meta name="description"> - Redirect chains — URLs with 3+ redirect hops
- Duplicate titles — multiple pages with identical title tag text
- Large page size — pages over 3MB
- Missing H1 — pages with no primary heading
Using Category Data
The category view answers the question: "What kind of SEO problems does the NKP portfolio have most?" When broken links dominate, the fix strategy is different (link auditing, 301 redirects) than when missing metadata dominates (batch meta description generation).
Per-domain counts are shown for each category so technicians can filter to specific issue types across the portfolio.
Data Source
All category data comes from Screaming Frog crawl exports. The Python ETL pipeline classifies each export row to a canonical issue type using Screaming Frog's issue code schema and stores the result in BigQuery's technical_seo dataset.
