Technical SEO for Generative Engines

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:

User-agent: *
Allow: /

User-agent: GPTBot
Allow: /

User-agent: Googlebot
Allow: /

Sitemap: https://presenciaia.com/sitemap.xml

2. 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:

/
├── /platforms/ (Hub)
│   ├── /platforms/chatgpt
│   └── /platforms/gemini
├── /methodology/ (Hub)
│   ├── /methodology/technical-seo
│   └── /methodology/geo-vs-seo
└── /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.

Metric	What It Measures	Target	Impact
LCP	Largest Contentful Paint	< 2.5s	Perceived loading speed
FID	First Input Delay	< 100ms	Interaction responsiveness
CLS	Cumulative Layout Shift	< 0.1	Visual content stability
TTFB	Time to First Byte	< 600ms	Server response speed
INP	Interaction to Next Paint	< 200ms	Overall responsiveness

Additional optimization:

Optimized images (WebP, responsive sizes)
Minified CSS and JavaScript
Resource compression enabled
CDN for global distribution

5. Metadata and Semantics

Metadata communicates to bots what your content is.

Metadata	Recommended Limit	Purpose
Meta title	50-60 characters	Title for search engines and AI, include main keyword
Meta description	120-160 characters	Summary with call to action
Canonical URL	Unique URL	Prevents duplicate content
Hreflang	Per language	Indicates versions in other languages
Schema.org JSON-LD	No limit	Structured data (Article, FAQPage, HowTo)

Additional implementation:

Meta robots: index, follow (for public content)
Open Graph tags (for social sharing)
Twitter Card tags
lang attribute in HTML
UTF-8 charset
