Eric Siu breaks down six SEO tactics that will tank your rankings in 2026: geo-spam, prompt injection tricks, low-quality AI scaling, keyword stuffing, over-chunking articles, and thin robotic pages. The core advice: write for humans, not algorithms.
These are the worst SEO strategies that you should avoid. Spamming GEO or prompt injection tricks. Trying to manipulate Google's AI overviews with hidden prompts or fake metadata gets flagged fast. D tier. Best of listicles written to promote yourself. Google's updates are devaluing self-serving top 10 lists and affiliate-heavy content. A tier. Scaling AI-generated content too fast. Publishing thousands of low-engagement AI posts at once triggers sitewide trust issues. C tier. Keyword and entity stuffing. Stuffing every variation of a topic hurts engagement, and the LLM services are cracking down. B tier. Overchunking content for SEO hacks. Breaking articles into unnecessary microsections makes them unreadable. Write for flow, not crawl. D-tier. Thin robotic pages made to trick LLMs. AI can now tell when your content was made for machines instead of people. S-tier. Follow for more AI strategies that actually work in the post-Google era.
