2POINT Agency Show all You said: a website can be made up of 2 sites - the site that appears when viewed on a pc or laptop, and a related site that appears when viewed on a mobile device. the mobile version could be arranged and formatted especially for optimized mobile viewing. is ai concerned or influenced by both versions or just the 'main' or pc / laptop vesion? AI models and search engines are heavily influenced by both versions, but they prioritize the mobile version above all else. This approach is driven by "Mobile-First Indexing," a standard where modern search algorithms (like Google’s) and advanced AI crawlers look almost exclusively at your mobile site to evaluate, rank, and understand your content. Here is how AI interacts with and is influenced by both versions of a website: 1. The Mobile Version is the "Primary" Source AI agents do not see the desktop version as the "main" site anymore. The Indexing Standard: When an AI bot or search crawler visits your website, it defaults to using a mobile user-agent. It reads the code, layout, and content exactly as it appears on a smartphone. The Risk of Hidden Content: If you remove text, accordions, or product descriptions from your mobile layout to save space, AI models will never see that information. To an AI, if it does not exist on the mobile site, it does not exist at all. 2. Parity Between Versions is Critical If your website uses two separate versions (often called an "M-dot" site, like ://example.com), the AI will compare them. Discrepancies create major issues: Structured Data: Your Schema markup and metadata must be identical on both the desktop and mobile versions. If the AI only finds structured data on the desktop version, it will likely ignore it. Link Architecture: AI relies on internal links to understand the relationship between your web pages. If your mobile site has simplified navigation with fewer links than the desktop site, the AI will struggle to crawl your deeper content. 3.
