Three acronyms have entered B2B marketing vocabulary in the space of about eighteen months, and most explanations of them are either too vague to act on or written for a global audience that ignores how differently these search behaviours play out for Indian B2B buyers. Here is a version built for a marketer who needs to brief a team or a client this quarter.
| Dimension | SEO | GEO | AEO |
|---|---|---|---|
| Target surface | Google/Bing results | ChatGPT, Gemini, Perplexity | Snippets + AI answers |
| Success metric | Rank position | Citation frequency | Snippet/answer capture |
| Measurement tooling | Mature (rank trackers) | Immature (manual audits) | Partial |
| Core lever | Authority + relevance | Credibility + originality | Content structure |
Almost every action that improves GEO or AEO also supports SEO, and vice versa: clear direct answers, named expertise, specific data, and clean structured data all help across all three surfaces simultaneously. Indian B2B teams that spin up three parallel workstreams with three separate budgets and three separate agencies usually end up duplicating research and producing inconsistent guidance for the same writers. The more effective model is one content-quality standard applied consistently, with three different measurement dashboards tracking how it performs on each surface.
SEO still drives the largest, most measurable share of organic traffic and pipeline for most Indian B2B companies today, and should remain the primary budget line. AEO is the structural discipline layered on top of existing SEO content that improves performance on both Google and AI surfaces at close to zero incremental cost. GEO is the newest and least measurable of the three, best treated as an emerging, lower-cost addition tracked through manual citation audits until better tooling exists, rather than a line item that displaces proven SEO investment.
The simplest way to remember it: SEO is about being findable, AEO is about being quotable, and GEO is about being trusted enough by a model to actually get quoted.
