Essential Optimization Areas
To optimize for AI search in 2024, focus on these key areas:
1. Comprehensive Schema.org Markup

2. Question-Answer Content Structure
Create content that directly answers user questions. AI search engines prefer:
- How-to guides (34%) - Step-by-step instructional content
- Expert opinions (28%) - Professional insights with credentials
- Case studies (22%) - Real-world examples with data
- News & updates (16%) - Timely content with clear dates
3. Content Freshness Signals
One of the most important findings for 2024: content updated within 90 days gets 2.8x more visibility in AI search results.
Best practices:
- Display "Last reviewed" dates prominently
- Update existing content rather than always creating new
- Keep review dates within 6 months
- Show timestamps for all factual claims

4. E-E-A-T Implementation
Google added "Experience" to E-A-T in 2024, creating E-E-A-T. This is now critical for AI search:
Experience - Demonstrate first-hand experience with the topic
Expertise - Display professional credentials and certifications
Authoritativeness - Build authority through testimonials and recognition
Trustworthiness - Ensure security, transparency, and source citations
5. Updated Core Web Vitals (2024)
New stricter requirements for 2024:
- LCP (Largest Contentful Paint): < 2.0s (reduced from 2.5s)
- INP (Interaction to Next Paint): < 200ms (replaces FID)
- CLS (Cumulative Layout Shift): < 0.1 (unchanged)
6. Server-Side Rendering
AI crawlers need immediate access to content. Key requirements:
- No JavaScript-dependent content
- Semantic HTML structure
- Proper heading hierarchy (H1 → H2 → H3)
- Alt text on all images
- Microdata in addition to JSON-LD
