No significant grammar or spelling errors
Why it matters
Grammar and spelling errors on a marketing site signal lack of care — and in markets where visitors are evaluating professional services, SaaS tools, or anything with a business trust component, lack of care in the copy creates doubt about quality of the product itself. The mental model is unconscious but consistent: if they didn't proofread the sentence the visitor just read, what else didn't they check? AI-generated copy is particularly prone to subtle errors: subject-verb disagreement ("your team are"), incorrect apostrophe use ("it's" vs. "its"), and plausible-sounding misspellings ("Intergration") that pass a casual read but fail on close inspection.
Severity rationale
Medium because grammar and spelling errors on key marketing pages — especially the hero — reduce perceived professionalism and create trust friction, particularly for business-to-business products where credibility is part of the evaluation.
Remediation
Before evaluating, extract the literal text from your rendered page (not the source code — rendered text avoids JSX noise) and paste it into a grammar checker. Use Grammarly's free browser extension, LanguageTool's browser extension, or paste directly at languagetool.org.
The mandatory quoting step: copy the hero section and first feature description as they appear in the browser and read them word by word before flagging pass. Common errors to look for:
Subject-verb agreement:
"Your team are going to love it" → "Your team is going to love it"
Apostrophe errors:
"It's features include..." → "Its features include..."
"The company began it's journey..." → "The company began its journey..."
AI misspellings:
"Intergration" → "Integration"
"Seamlesly" → "Seamlessly"
"Definitly" → "Definitely"
For AI-built projects: run the generated copy through a grammar checker in a separate pass from generation — the same AI session that generated the copy is biased toward its own output being correct.
