Frequently Asked Questions

Mobile optimization is critical because over 65% of AI-powered searches now originate from mobile devices. Google's mobile-first indexing means AI crawlers see your mobile site as the primary version of your content. If your mobile experience is poor, AI systems may either struggle to crawl your content effectively or deem it unsuitable for citation in AI-generated answers.

AI systems like Google AI Overviews, ChatGPT, and Perplexity factor in page quality signals when selecting content to cite. Poor mobile Core Web Vitals, accessibility issues, and slow load times signal to AI that your content may provide a poor user experience. This can result in your content being passed over in favor of mobile-optimized competitors, even if your content is more comprehensive.

We recommend a minimum Mobile Optimization Score of 70 to maintain competitive AI visibility. Scores below 50 indicate critical mobile issues that likely prevent AI systems from effectively crawling and citing your content. The top-performing sites in AI search results typically score 85 or higher, so aiming for excellence gives you a significant competitive advantage.
