Google’s top trending Halloween costumes revealed — and you may have never heard of them

Google’s release of its top trending Halloween costume searches for 2026, highlighting blockbuster movies and obscure characters, signals a surge in niche keyword interest that will drive seasonal traffic spikes to related sites. For website owners, this means that AI-driven bots—especially those indexing costume retailers, DIY tutorial blogs, and fan forums—will intensify crawling activity around late October, targeting both popular titles and the newly surfaced characters. The influx can inflate server load, skew analytics, and potentially expose sites to malicious scraping if not properly managed. Moreover, the unexpected popularity of obscure costumes may lead to content‑policy mismatches for platforms that restrict copyrighted or adult‑themed imagery, requiring clearer compliance signals. **Actionable tips:** 1. Update your llms.txt file now to explicitly allow reputable AI crawlers (e.g., Googlebot‑Image, BingPreview) while disallowing unknown or aggressive bots that target costume‑related URLs. 2. Deploy rate‑limiting rules in your web server or CDN to throttle requests from IP ranges associated with high‑volume AI scrapers during the Halloween window. 3. Use llmscentral’s monitoring dashboard to set alerts for sudden spikes in bot traffic to costume‑keyword pages, enabling rapid response before performance or policy issues arise.
