Gustav Two disciplines, one goal
SEO and GEO are both about making a business visible when potential customers are searching for information. The difference lies in where that search happens and what a good result looks like.
SEO has existed since the early days of the internet and is well established. GEO is newer and has emerged in response to a shift in search behaviour: a growing share of searches now happens inside AI assistants like ChatGPT, Perplexity, and Google AI Overview, rather than in classical search engine results.
What is SEO?
Search Engine Optimization is the process of making your content visible in traditional search engine results. When someone searches on Google and clicks on one of the organic results, it is SEO that placed that page there.
SEO works across three main areas. The first is technical quality: page speed, mobile optimisation, correct page structure, and error-free indexing. The second is content: relevant keywords, thorough answers, and material that matches the search intent. The third is authority: links from other credible sites that signal to Google that your content is worth trusting.
The result of good SEO is a click. The user sees a list of results and chooses to click on your page.
What is GEO?
Generative Engine Optimization is the process of making your content the source AI search tools cite when someone asks a question. A full explanation of the concept is in the article What is GEO?
The key point is this: instead of a user seeing a list of results and clicking, the AI assistant generates an answer and decides what to cite. The user asks, the AI answers, and either your business is mentioned in the answer or it is not.
That is fundamentally different from SEO. You are not competing for a click. You are competing to be mentioned as a source at all.
The central differences
| Dimension | SEO | GEO |
|---|---|---|
| Search platform | Google, Bing (classical search) | ChatGPT, Perplexity, Google AI Overview, Copilot |
| What matters | Keywords, backlinks, technical performance | Content quality, entity recognition, clear Q&A structure |
| The result | A click to your website | Your business cited in the AI answer |
| User chooses | Yes, from a list of results | No, the AI selects the source |
| Time horizon | Weeks to months | Weeks to months (comparable) |
What they have in common
More than you might expect. AI models draw on indexed content, and many of the signals they weight are the same signals Google weights in SEO. Clear and direct content that answers specific questions is good for both. Correct schema markup helps both. FAQ sections are effective in both contexts. Consistent description of your business across pages and platforms strengthens both.
In practice, an SEO project done well already covers much of the groundwork for GEO. The two disciplines are complementary, not competing.
A good rule of thumb: start by having a good answer to a specific question. A good answer is good for SEO and good for GEO. It is the foundation for both.
What should your business prioritise?
For most businesses, SEO remains the foundation. It is the established system, it is where the largest volume of search traffic still happens, and a healthy SEO base is the prerequisite for GEO work having any effect. If your site is technically weak and your content is thin, GEO efforts will produce limited results.
GEO is the natural next layer. Once the SEO foundation is in place, GEO work is about structuring and writing content so AI models can draw on it with confidence. That does not require a complete rebuild of existing content, but a systematic review and adjustment.
Businesses that are already visible in Google and want to maintain that visibility as AI search grows in use should start GEO work now. It is an accumulating investment, and those who start early build authority before the competition intensifies.
