SEO Audit
Identify SEO issues and provide actionable recommendations.
Before starting
Ask:
- What type of site is it? (SaaS, e-commerce, blog, local)
- What are the priority pages or keywords?
- Any known issues or recent changes?
- Search Console or analytics access?
Priority order
- Crawlability and indexation
- Technical foundations
- On-page optimization
- Content quality
- Authority and links
Technical checks
- robots.txt: no unintentional blocks, sitemap reference
- Sitemap: valid, submitted, indexable URLs
- Indexation:
site:domain, canonicals, noindex, soft 404s
- Core Web Vitals: LCP < 2.5s, INP < 200ms, CLS < 0.1
- Mobile: responsive, viewport, tap targets
- HTTPS: valid certificate, no mixed content, redirects
- URL structure: lowercase, hyphens, no unnecessary parameters
On-page checks
- Unique title tags (50-60 chars)
- Unique meta descriptions (150-160 chars)
- One H1 per page with primary keyword
- Image alt text, compressed, modern formats
- Internal linking, no orphan pages
- Clear keyword targeting without cannibalization
Content checks
- E-E-A-T signals: experience, expertise, authority, trust
- Sufficient depth for the topic
- Updated and current information
- No thin or duplicate content
International SEO
- Self-referencing hreflang with return tags
- Valid language-region codes
x-default present- No cross-locale canonicals
Schema markup
web_fetch and curl cannot reliably detect JS-injected JSON-LD. Use a browser tool, Google's Rich Results Test, or a rendered export.
Output
Produce a report with:
- Executive summary and top 3-5 priorities
- Technical findings (issue, impact, evidence, fix, priority)
- On-page findings
- Content findings
- Prioritized action plan
