One thing we changed after client feedback: instead of a summary paragraph, our SEO reports now open with the actual before/after Health Score from the same audit tool, plus the Page Health Ratio (percent of pages free of critical errors). Clients can verify it independently instead of trusting a write-up.
Full breakdown of what's in the report: https://yositeup.com/services/seo-optimization/work-report
Curious if others building in the SEO/marketing space run into the same "trust me" problem with deliverables, and how you solved it.
