The 5 Pillars of Technical SEO for GEO
Technical SEO is the foundation on which all GEO strategies rest. Without solid technical foundations, no content will be indexed correctly by ChatGPT, Gemini, or Google.
1. Crawlability and Accessibility
AI bots need to be able to reach your content without obstacles.
Crawlability Checklist:
Your domain allows access without blocking JS or AJAX
You don't have important directories blocked in robots.txt
Your site loads in less than 3 seconds (speed is critical)
You don't use authentication channels to block public content
Your sitemap.xml is updated and linked in robots.txt
You don't have X-Robots-Tag headers that block crawling
You explicitly allowed access to GPTBot and Googlebot in robots.txt
Example code in robots.txt:
text
User-agent: *
Allow: /
User-agent: GPTBot
Allow: /
User-agent: Googlebot
Allow: /
Sitemap: https://presenciaia.com/sitemap.xml2. URL Structure
URLs communicate information about your content to bots.
Best practices:
Descriptive and text-based URLs (not random numbers)
Use hyphens (-) to separate words, not underscores (_)
Hierarchical structure: /category/subcategory/article
Language-friendly URLs: /es/articulo vs /en/article
Avoid unnecessary parameters (utm, tracking)
Consistent URLs (no random variables)
Moderate length (maximum 75 characters)
3. Site Architecture
Your site's hierarchy must be clear to bots and humans.
Recommended structure:
text
/
├── /platforms/ (Hub)
│ ├── /platforms/chatgpt
│ └── /platforms/gemini
├── /methodology/ (Hub)
│ ├── /methodology/technical-seo
│ └── /methodology/geo-framework
└── /glossary/ (Hub)
└── /glossary/[terms]No more than 3-4 levels deep from root
Internal URLs linked from home page
Breadcrumbs implemented (improves navigation)
XML sitemap with all hubs and pages
Clear and accessible navigation menu
4. Core Web Vitals and Performance
Google (and by extension, Gemini) prioritizes fast sites.
Critical metrics:
LCP (Largest Contentful Paint) < 2.5 seconds
FID (First Input Delay) < 100 milliseconds
CLS (Cumulative Layout Shift) < 0.1
TTFB (Time to First Byte) < 600 ms
Image optimization (WebP, responsive sizes)
CSS and JavaScript minification
Resource compression
CDN for global distribution
5. Metadata and Semantics
Metadata communicates to bots what your content is.
Essential implementation:
Meta title (50-60 characters, include main keyword)
Meta description (120-160 characters, call to action)
Meta robots: index, follow (for public content)
Canonical URL (prevents duplicate content)
Hreflang for multi-language pages
Open Graph tags (for social sharing)
Twitter Card tags
Schema.org JSON-LD (Article, FAQPage, CollectionPage)
lang attribute in HTML
- [ ] UTF-8 charset
