SEO: from keyword stuffing to entity-driven search
SEO has had three eras. Keyword density, backlinks, and now entities. AI search rewrites the rules again.
Before · keyword stuffing
For a decade, SEO was about keyword density, backlink farms, and exact-match domains. Google's early algorithms could be gamed, and they were — at scale.
Then Penguin and Panda happened. Hundreds of thousands of sites lost rankings overnight. The shape of the web shifted.
Now · entities and intent
Today's SEO is about entities, intent, and topical authority. Google understands that "best billing software in Nellore" maps to a real business intent — not a keyword. Schema.org markup, knowledge-graph relationships, and content depth matter more than density.
Core Web Vitals, mobile-friendliness, and HTTPS are now table stakes. The technical layer is enforced.
The next era · AI search
Generative search (Google's AI Overviews, Perplexity, ChatGPT browse) changes the rules again. Some queries will never see a blue link. The winning strategy is being the source the AI cites — which means content authority, brand mentions, and structured data become more important, not less.
SEO survives. It just keeps changing what "S" means.
