Most SEO checklists you'll find online were written for 2018. They cover titles, meta descriptions, and a sprinkling of Core Web Vitals — and then they stop. In 2026, that's roughly half of what actually moves the needle.
Here's the full nine-category framework we use to grade every site that runs through SEOGrade.ai. If your audit tool doesn't cover all nine, it's incomplete.
The Foundations
These three are table stakes. If you fail here, nothing else matters.
1. Crawlability
Can search engines and AI crawlers actually reach your pages?
- Sitemap submitted to Google Search Console and Bing
- Robots.txt allows the bots you want (and explicitly handles
GPTBot,ClaudeBot,PerplexityBot) - HTTPS enforced with no mixed-content warnings
- Canonical tags present on every indexable page
2. Technical Health
- Core Web Vitals in the green for 75% of real-user sessions
- Mobile-first rendering with no layout shift
- Structured data validated (Org, Product, Article, FAQ at minimum)
- Image hygiene: WebP, lazy loading, descriptive alt text
3. On-Page
The classics still matter — they're just not enough on their own.
- Unique, intent-matched titles under 60 characters
- Meta descriptions that earn the click
- One H1 per page, descriptive subheadings, scannable structure
- Internal linking that distributes authority and surfaces deep pages
The Modern Layer
This is where 90% of audit tools stop. It's also where the easy wins are.

4. Content & E-E-A-T
Google explicitly grades for experience, expertise, authoritativeness, and trust. Show your work: author bios, citations, original research, last-updated timestamps.
5. Authority
Backlinks, brand mentions, and unlinked citations from the publications your audience reads. Quality > quantity.
6. AI Citability
Can ChatGPT and Claude actually extract clean answers from your pages? FAQ schema, definition blocks, and TL;DRs make you quotable.
7. GEO (Generative Engine Optimization)
Entity presence on Wikipedia, Crunchbase, and G2. Structured data that LLMs can ingest. Brand-association signals that show up in training data.
8. pSEO
Programmatic SEO opportunity at scale — templates, data sources, and the indexable surface area you're leaving on the table.
9. Local SEO
Google Business Profile, NAP consistency, citations, reviews, and location-specific landing pages. Critical if you serve a geography.
The bottom line
Run your site through all nine. The categories you score worst on are the ones your competitors are quietly winning. Fix those first.
