SEO vs GEO: what's the difference?

Short answer

SEO optimizes pages for Google rankings and clicks. GEO (Generative Engine Optimization) optimizes data to be cited by LLMs in an answer — the click disappears but the mention remains, which changes ROI measurement.

Examples in Quebec

Quebec company profiles from the ManuGEO directory related to this topic. Their presence here illustrates the kind of public profile this answer discusses; it does not mean they are already cited by AI engines.

When reviewing them, look at what an AI engine can extract: a precise activity rather than a slogan, the city, key facts with their source and date, an FAQ that answers buyer questions, and structured data consistent with the official website.

Data and sources

  • Gartner predicts traditional search engine volume will drop 25% by 2026, shifting to AI chatbots and virtual agents.

    This is a forecast, not a measurement; it still signals that part of supplier searches will go through generated answers.

  • B2B buyers spend only 17% of their buying time meeting with potential suppliers.

    Most of the evaluation happens without you, so what your public pages say about your capabilities weighs heavily in the shortlist.

  • As of 2024, over 45 million web domains mark up their pages with over 450 billion Schema.org objects.

    Structured data is a widely adopted standard; a supplier that publishes none gives engines less explicit information.

Frequently asked questions

Where should I start if my site has none of this yet?

Start with access: check that robots.txt does not block AI engine crawlers and that a sitemap.xml lists your pages. Then add an accurate Organization JSON-LD and one page per core activity with quantified facts. These steps require little development.

Do these optimizations hurt my Google rankings?

No. The same foundations serve classic SEO and AI answer visibility: accessible pages, precise content, valid structured data and consistent links. Just avoid repetitive mass-produced pages, which help neither.

How do I measure the effect of these changes?

Set a list of 10 to 15 buyer questions, record today whether your company is named and with which source, then repeat the test monthly. Track indexing in Google Search Console in parallel. Compare equivalent periods rather than isolated snapshots.
