SEO vs AEO vs GEO: What’s the Difference and What You Should Care About
AI is changing the way we do business online.
Not long ago, the primary focus of cannabis marketing was simple: rank in the number one spot on Google. Today, that focus is expanding. Businesses aren’t just thinking about SEO anymore, they’re also trying to understand how to show up in AI-driven search experiences.
With more than 2.5 billion prompts sent to ChatGPT alone every day, AI tools like ChatGPT, Google Gemini and Microsoft Copilot are becoming modern-day search engines. Millions of users now rely on AI to research products, compare services and make decisions, often without ever clicking a traditional search result.
As a result, new terms like AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) have entered the conversation. For many business owners, that’s raised some valid questions: Is SEO dead? Is AEO replacing SEO? What’s the difference between AEO and SEO and which is better?
Rest assured, SEO isn’t dead or being replaced by AEO. In fact, they’re not so different after all.
SEO vs AEO vs GEO VS LLMO
At first glance, it appears that there are dozens of new strategies you need to be implementing to your website. But the truth is, SEO vs AEO (and all the others) isn’t that complex. In fact, we’d go as far as saying they’re all related.
SEO (Search Engine Optimization)
SEO is the practice of optimizing website content so it can be crawled, indexed and ranked into traditional search engine results. This is best used for discoverability, long-term organic traffic and building a foundation for your visibility.
AEO (Answer Engine Optimization)
AEO focuses on structuring content so it can be directly answered by search engines and AI assistants, often through featured snippets, FAQs or voice search responses.
GEO (Generative Engine Optimization)
GEO is the practice of optimizing content so it can be retrieved, selected, cited and assembled by generative AI systems like AI search overview and AI-powered assistants.
LLMO (Large Language Model Optimization)
LLMO refers to optimizing content so large language models can accurately interpret, summarize and reference it when generating responses.
The Evolution of Search Engines and Results
Everyone knows SEO as the original ranking system. It emerged as a way to help search engines understand, index and display web pages based on the authority, quality and relevance of their content. Brands that invest in SEO tend to gain organic traffic, credibility and authority by appearing at the top of search results.
As search engines became better at understanding search intent, AEO emerged. Instead of simply ranking pages, search engines began answering questions directly through instant responses like featured snippets.
Now, as AI becomes one of the primary ways people search for information, we’re seeing GEO as the next evolution of search engine ranking systems where content is being optimized for AI overview selection based on credibility, unbiased opinions and usefulness.
How SEO, AEO and GEO Work Together
The mistake most cannabis brands make is treating SEO, AEO and GEO as separate tactics, when in reality, they share the same goal of ranking in AI-search results.
Let’s first look at AEO, GEO and LLMO. Each term emphasizes a slightly different angle — quick answers, generative systems, AI outputs or language models — but the underlying goal is identical. Optimizing for each of them focuses on creating clear content that can be retrieved, understood and used by AI systems when generating responses.
Strong SEO is what makes all of this possible. SEO ensures content is discoverable, crawlable and properly indexed into a search database. From there, clear structure and intent-driven content naturally supports AI understanding, which enables selection and citation.
In other words, when SEO is done well, it creates the conditions for AEO/GEO/LLMO.
Common Misconceptions About SEO, AEO and GEO
Let’s address some of the common misconceptions we hear about SEO and AI search optimization.
Is SEO dead?
SEO isn’t dead. People often say that SEO is dead, but that’s really just because the quick rank tactics that people used to use don’t work anymore. Today, SEO requires patience, strategy and consistency.
Will AEO replace SEO?
AEO isn’t going to replace SEO. In fact, AEO is highly dependent on SEO.
Is GEO replacing SEO?
GEO isn’t replacing SEO. SEO focuses on discoverability and ranking pages while GEO focuses on being selected as a source in an AI-generated response. In order for AI to find you, your site needs to be easy to read, aka have good SEO.
If I rank #1, will AI use my content?
Not necessarily. AI systems don’t choose sources based on rankings alone. They evaluate clarity, credibility and structure at the content level. It’s common for AI to pull answers from lower-ranking pages if they are easier to parse and more trustworthy in context.
