Great practical guide. The GEO section is especially timely — most Next.js SEO guides still focus exclusively on traditional Google ranking signals and completely ignore how AI search engines consume content.
One thing worth emphasizing: the llms.txt standard you mentioned is becoming increasingly important. Beyond just having one, the content structure matters. AI models parse pages differently from Googlebot — they favor clear hierarchical headers, direct answers in the first paragraph, and structured data that provides entity relationships rather than just metadata.
For Next.js specifically, I've found that the App Router's server components actually give you an advantage for AI crawlability since the content is fully rendered server-side by default. The old Pages Router with heavy client-side rendering was essentially invisible to most AI crawlers.
Also worth noting: if you're using ISR (Incremental Static Regeneration), make sure your revalidation intervals are short enough that AI crawlers pick up fresh content. Some AI engines cache aggressively, so stale ISR pages can persist in AI search results longer than you'd expect.
Exactly right — llms.txt is becoming the robots.txt equivalent for AI crawlers. What's interesting is that it goes beyond just access control. With llms-full.txt you can provide structured context that helps AI models understand your content better, which directly impacts whether they cite you in responses. I've been tracking how different AI search engines handle these files, and adoption is growing fast among content-heavy sites.
