Case-study evidence
Evidence required: source materials for each published result, permission to disclose what is shown, and a page that explains context, the copywriter's role, work performed, constraints, and supportable outcomes.
Pass condition: every material case-study claim can be substantiated. The source previously cited a typical 15-30 percent conversion lift, but no supporting source is embedded here, so it must not be presented as a verified benchmark or promised result.
Severity: critical when a page contains invented or unverifiable client outcomes. Owner: copywriter or account owner. Corrective action: remove unsupported claims, add missing context, and publish only evidence that can be responsibly disclosed. Validation: fact-check the final page against the underlying records and permissions. Tools: Google Analytics 4, Hotjar
Professional biography and credentials
Evidence required: an About page, author information, and documentation for credentials or memberships that are publicly claimed. Pass condition: role, experience, certifications, memberships, and specialist claims are accurate, current, and relevant to the work offered.
Severity: high when inaccurate credentials affect client due diligence. Owner: copywriter. Corrective action: replace vague authority language with specific, supportable experience and remove expired or unverifiable claims.
Validation: independently open referenced credential or membership sources where available and compare them with the site. Tools: Grammarly, Hemingway Editor
Client logos and testimonials
Evidence required: permission or contractual right to display logos and testimonials, plus the original testimonial wording or approved edited version. Pass condition: displayed proof is authentic, accurately attributed, and not selectively framed to imply a result that was not stated.
Severity: high when social proof is fabricated, altered materially, or used without permission. Owner: copywriter or business owner. Corrective action: remove unverified proof and request permission or replacement evidence where appropriate.
Never use review gating or incentives to suppress negative feedback. Validation: keep a record of approval and compare published text with the approved source. Tools: Senja, Testimonial.to
Educational internal linking
Evidence required: a crawl and manual review showing how the <a href='/industry/professional/copywriter'>copywriter service context</a>, educational guides, and the existing /guides/copywriter-seo-mistakes resource connect.
Pass condition: educational pages link to relevant services and related guidance where that next step is useful, without stuffing anchors or forcing unrelated links. Severity: medium. Owner: content or SEO owner.
Corrective action: add descriptive contextual links, remove misleading links, and ensure important service pages are not orphaned. Validation: recrawl and manually follow the revised paths from representative educational pages. Tools: Internal Link Juicer
