Does keyword density still matter for AI search?

No. Answer engines like ChatGPT, Perplexity, and Gemini parse meaning, not term frequency. There is no density target to hit. Repeating a phrase to reach some percentage adds no signal the model uses to decide what to cite. Write naturally, cover the entities and sub-questions the topic implies, and let the model extract self-contained facts rather than counting words.

Will keyword stuffing get my page penalized?

On classic Google search, keyword stuffing has been a spam signal for years. On answer engines, the GEO study found it produced no visibility lift and was about 10% worse on Perplexity — so it actively cost citations there. The risk is no longer a manual penalty but exclusion: padded, low-density-of-fact pages are simply not the cleanest source for a model to quote.

How is writing for AI different from writing for Google?

Less than you'd think. Both reward clear, crawlable, well-structured content. The shift is from matching query strings to supplying extractable facts: a quotable sentence, a cited statistic, a clean definition. You're optimizing for a machine that lifts a claim out of context, so each claim must stand alone and carry its source. Same hygiene, different unit of value.

What replaces the old keyword research workflow?

Entity and question mapping. Instead of chasing exact-match phrases, list the entities, sub-questions, and comparisons a topic implies, then make sure each has a direct, sourced answer on the page. You still use keyword tools to understand demand and language, but the deliverable is coverage and citability, not a density quota baked into prose.

Can I just add statistics everywhere to game AI citations?

No. The lift in the GEO study came from relevant, accurate quotes and statistics that genuinely support the claim — not decoration. Fabricated or off-topic numbers erode trust and are easy for fact-checking layers to flag. The durable move is to source real data, attribute it inline, and only cite figures that strengthen the specific point you're making.

Keyword stuffing doesn't help AI search and can hurt you on Perplexity. The GEO study shows quotes, statistics, and citations win. Here's what to do instead.
