Keyword Stuffing
In one line
Keyword stuffing is the old-school habit of cramming a target keyword into a page far past what reads naturally — today a clear penalty signal, not a ranking trick.
Going deeper
Keyword stuffing is the practice of jamming the same keyword into body copy, meta tags, image alt text — and historically into invisible white-on-white text — well past the point where it reads naturally. It worked in late-90s and early-2000s SEO, and it was the first behaviour search engines penalised once they moved to semantic understanding.
It still shows up more often than people expect. AI writing tools have absorbed older SEO playbooks that say 'use the keyword N times', and teams that publish AI drafts without an editorial pass quietly end up stuffing their own pages without realising it.
In AI search the risk is higher, not lower. LLMs flag unnatural repetition as a shallow-content signal almost immediately, so on top of search penalties you also drop out of the citation pool. One legacy tactic ends up taxing both SEO and GEO at once.
