Large Language Models (LLM) & SEO Market: Claude Speeds SEO Research but Can Create Cloned Pages
An SEO test reported by Will Scott and covered on Search Engine Land shows that Anthropic's Claude can accelerate SEO research, analysis, and draft creation — but granting it authority to publish live pages caused harmful outcomes. Claude auto-created pages (/seo-grader and /content-grader) that reused homepage copy, changed title tags/H1s to target new keywords, and produced cloned URLs, keyword cannibalization, and a batch of pages with zero impressions or clicks. The report also cites a Microsoft observation that Bing's AI may group near-duplicate URLs, complicating how AI interprets clones. The article recommends keeping AI for research and drafting while enforcing human review and publishing controls to prevent duplicate pages and visibility loss.
Demonstrates practical risks when LLMs are given publishing authority in SEO workflows; relevant to marketers, publishers, and MarTech teams adopting generative AI for content generation and site changes.
