Google Experts: SEO Fundamentals Remain Despite AI Integration

At the recent Search Central Live event, Google search experts Gary Illyes and Cherry Sireetorn Prommawin provided crucial insights about AI's role in search while reassuring marketers that core SEO principles remain unchanged. Their presentation, later endorsed by Google senior product expert Kenichi Suzuki on LinkedIn, offers authoritative guidance for navigating SEO in the AI era.

AI Features Built on Traditional Search Infrastructure

The experts emphasized that emerging AI features like overviews and modes operate on the same foundation as traditional Google search. Key systems including Googlebot, the search index, and ranking algorithms continue to drive results - whether AI-generated or conventional.

"Websites don't need special 'AI SEO' strategies," Illyes stated. "Following Google's established quality guidelines ensures good performance across all result types." The team specifically noted that content origin (human or AI) doesn't factor into rankings - only quality, usefulness and credibility matter.

How AI Enhances Each Search Stage

The presentation detailed AI's integration throughout Google's search pipeline:

• Crawling: AI helps determine optimal website crawl timing
• Indexing: BERT language model analyzes text meaning and filters low-value pages
• Spam Detection: SpamBrain system identifies and removes spam content
• Query Processing: RankBrain interprets novel or uncommon search queries
• Multimedia Integration: MUM model combines information from text, images and videos
• Result Generation: AI overviews decompose queries into sub-questions for comprehensive answers verified against Google's index

The Click-Through Rate Challenge

While affirming SEO continuity, the experts acknowledged new challenges. A Pew Research Center study revealed:

• Regular result click-through rates dropped from 15% to 8% when AI summaries appear
• Only 1% of users click source links within AI overviews This data suggests websites may need to adapt their traffic acquisition strategies even as ranking factors stay consistent.

Key Points:

1. Core SEO principles remain valid despite AI integration
2. Google evaluates content quality regardless of human/AI origin
3. Multiple AI systems enhance different search stages
4. Traditional ranking signals still determine visibility
5. AI summaries may significantly impact website traffic patterns
