/seo-auditInputs
Gather the following from the user. If not provided, ask before proceeding:
-
URL or domain — the site to audit, or a topic/keyword if running in keyword research mode
-
Audit type — one of:
- Full site audit — end-to-end SEO review covering all sections below
- Keyword research — identify keyword opportunities for a topic or domain
- Content gap analysis — find topics competitors rank for that you don't
- Technical SEO check — crawlability, speed, structured data, and infrastructure issues
- Competitor SEO comparison — head-to-head SEO benchmarking against specific competitors
If not specified, default to full site audit. -
Target keywords or topics (optional) — specific keywords the user is already targeting or wants to rank for
-
Competitors (optional) — domains or companies to compare against. If not provided and the audit type requires competitor data, use web search to identify 2-3 likely competitors based on the user's domain and keyword space.
Process
1. Keyword Research
Research keywords related to the user's domain, topic, or target keywords.
If ~~SEO tools are connected:
- Pull keyword data, search volume, keyword difficulty scores, and ranking positions automatically
- Identify keywords the site currently ranks for and where it's gaining or losing ground
If ~~product analytics are connected:
- Cross-reference keyword targets with actual organic traffic data to validate which keywords are driving visits and conversions
If tools are not connected:
- Use web search to research the keyword landscape
- Note: "For more precise volume and difficulty data, connect an SEO tool like Ahrefs or Semrush via MCP. The audit will auto-populate with ranking data."
For each keyword opportunity, assess:
- Primary keywords — high-intent terms directly tied to the user's product or service
- Secondary keywords — supporting terms and variations
- Search volume signals — relative demand (high, medium, low) based on available data
- Keyword difficulty — how competitive the term is (easy, moderate, hard)
- Long-tail opportunities — specific, lower-competition phrases with clear intent
- Question-based keywords — "how to", "what is", "why does" queries that mirror People Also Ask results
- Intent classification — informational, navigational, commercial, or transactional
2. On-Page SEO Audit
For each key page (homepage, top landing pages, recent blog posts), evaluate:
- Title tags — present, unique, within 50-60 characters, includes target keyword
- Meta descriptions — present, compelling, within 150-160 characters, includes a call to action
- H1 tags — exactly one per page, includes primary keyword
- H2/H3 structure — logical hierarchy, uses secondary keywords where natural
- Keyword usage — primary keyword appears in the first 100 words, used naturally throughout, not over-stuffed
- Internal linking — pages link to related content, orphan pages identified, anchor text is descriptive
- Image alt text — all images have descriptive alt attributes, keywords included where relevant
- URL structure — clean, readable, includes keywords, no excessive parameters or depth
3. Content Gap Analysis
Identify what's missing from the user's content strategy:
- Competitor topic coverage — topics and keywords competitors rank for that the user's site does not cover
- Content freshness — pages that haven't been updated in 12+ months and may be losing rankings
- Thin content — pages with insufficient depth to rank (under 300 words for informational queries, lacking substance)
- Missing content types — formats competitors use that the user doesn't (guides, comparison pages, glossaries, tools, templates)
- Funnel gaps — missing content at specific buyer journey stages (awareness, consideration, decision)
- Topic clusters — opportunities to build pillar pages with supporting content
4. Technical SEO Checklist
Evaluate technical foundations that affect crawlability and rankings:
- Page speed — identify slow-loading pages and likely causes (large images, render-blocking scripts, excessive redirects)
- Mobile-friendliness — responsive design, tap targets, font sizes, viewport configuration
- Structured data — opportunities for schema markup (FAQ, HowTo, Product, Article, Organization, Breadcrumb)
- Crawlability — robots.txt configuration, XML sitemap presence and accuracy, canonical tags, noindex/nofollow usage
- Broken links — internal and external 404s, redirect chains
- HTTPS — secure connection, mixed content issues
- Core Web Vitals signals — LCP, FID/INP, CLS indicators based on observable page behavior
- Indexation — pages that should be indexed but may not be, duplicate content risks
5. Competitor SEO Comparison
For each competitor, compare:
- Keyword overlap — keywords both sites rank for, and where each site ranks higher
- Keyword gaps — terms the competitor ranks for that the user does not
- Domain authority signals — relative site strength based on backlink profiles, referring domains, and content depth
- Content depth — average content length, topic coverage breadth, publishing frequency
- Backlink profile observations — types of sites linking to competitors, link-worthy content they've produced
- SERP feature ownership — which competitor appears in featured snippets, People Also Ask, image packs, or knowledge panels
- Technical advantages — site speed differences, mobile experience, structured data usage

Follow-Up
After presenting the audit, ask:
"Would you like me to:
- Draft content briefs for the top keyword opportunities?

- Build a content calendar based on the gap analysis?
- Dive deeper into any specific section of the audit?
- Run this same analysis for a different competitor or domain?"
