Vanaxity insights tagged JavaScript rendering - notes on AI content, SEO, GEO and AEO from Van Data Team.
Technical SEO debt used to cost you crawl budget and rankings, but it now costs AI search visibility too, because testing by Vercel and MERJ found that none of the major AI crawlers execute JavaScript, so anything rendered in the browser is invisible to ChatGPT, Claude, and Perplexity, and since those crawlers already fetch at roughly a quarter of Googlebot's volume, the practical answer is to reserve a fixed slice of every sprint for debt paydown, prioritize by revenue impact rather than audit severity, and check what bots actually see rather than what your browser shows.
