What is GEO (Generative Engine Optimization)?
GEO, or Generative Engine Optimization, is the practice of structuring and writing web content so that AI systems, such as ChatGPT, Google's AI Overviews, and other large language models are more likely to surface, cite, and summarize it in their responses.
GEO vs. SEO: Key Differences
| SEO | GEO | |
| Primay Audience | Search engine crawlers | AI language models |
| Goal | Rank on a results page | Be cited or quoted in an AI response |
| Success metric | Click-through rate, page ranking | Mentions in AI-generated answers |
| Link strategy | Outbound links to credibility-signal sources | Own the expertise; minimize sending readers away |
| Content style | Keyword-optimized, structured for scanners | Authoritive, factual, clearly reasoned |
| Trust signal | Backlinks and domain authority | Demonstrated depth of knowledge on your own site |
The central insight of GEO-first content strategy: AI models synthesize and cite sources that demonstrate expertise directly, rather than sources that point to expertise elsewhere. This post explores what that shift means for how you write and link.
Ready? Let's go!
This post is about cat food. But not really.
It's a true story, about a brand we've worked with for a long time. But to avoid naming names, we're going to change the details, and say that they are a cat food brand.
So, we created a cat food brand to help tell this story. We came up with a logo, packaging, and then the lifestyle image you see here. It took us about ten minutes, using PixelBrief, which we recommend that you try out if you'd like to launch a cat food brand, or any other sort of brand, for that matter.
We recently did a complete redesign of one of this brand's sites. We're not just talking about a new paint job; we seriously rethought how to build a site that drives engagement and gets organic traffic from search engines and LLMs. It worked; within a couple of days of launching the new site, daily traffic grew by 500%.
Part of the job was migrating their extensive set of blog posts. It was lots of great content, some going back more than five years. Their blog content had traditionally driven about half of their organic traffic, but it had dropped significantly at around the time that Google introduced AI search mode, as it has for so many other brands. Between Google intercepting clicks with its AI summaries and more and more people turning to AI chat apps like ChatGPT, this is why GEO, or generative engine optimization is so important. And that's why we offer GEO as a service.
Anyway, back to Meow Chow and their blog content.
A lot of that blog content had been written with SEO tactics that were considered best practice at the time. One of the most common was festooning articles with outbound links to authoritative, high-credibility sites (think academic journals, research institutions, and government health agencies). The thinking made sense back then: Google's algorithm looked favorably on content that cited credible sources, treating those links as a signal that your content was well-researched and trustworthy. It was the digital equivalent of footnotes in an academic paper.
So, sprinkled throughout these posts, you'd find phrases like "cat obesity" hyperlinked to a study on the National Institute of Cat Health (not a real institute as far as we know, but let's roll with it), or "taurine deficiency" pointing to some dense research paper that approximately four people had ever read voluntarily. On the surface, it looked rigorous. Authoritative, even.
But there were a couple of problems with this approach.
First, many of these links were only loosely related to the surrounding content. They'd been inserted to hit some arbitrary quota of outbound links rather than to genuinely serve the reader. A casual visitor clicking through to a dry academic abstract wasn't going to have a great experience, and they certainly weren't coming back to the cat food blog.
Second (and this is the more obvious issue in hindsight) those links were actively walking readers out the door. Every click was a small act of self-sabotage, handing hard-won traffic to someone else's site.
So what's the right approach today?
The good news is that outbound links to authoritative sources haven't become useless. They've just become more honest. Well-placed, relevant outbound links to authority sites can improve content trust signals, which matters both for traditional SEO and for how AI models evaluate your content.
But, Google's own John Mueller has been pretty direct about this:
"Treat links like content. Does this link provide additional, unique value to users? Then link naturally. Is this link irrelevant to my users? Then don't link to it."
The era of link-stuffing as a numbers game is over.
So yes, link out to authoritative sources, but do it sparingly, and do it transparently. Rather than burying a naked hyperlink inside a generic phrase like "cat obesity," give your reader something they can actually use. Write it out: "According to a study by the National Institute of Cat Health, nearly 30% of housecats are overweight." Now the reader knows what they're getting before they click, the claim is properly sourced, and the link earns its place.
But here's where it gets interesting, and where the old SEO mindset starts to work against you.
When you cite an external source that compellingly, you're lending that source your credibility, and to some degree, giving it away.
In the world of GEO, authority isn't just a ranking signal; it's the currency that determines whether AI systems treat your content as a source worth drawing from. Search engines and AI models alike are increasingly rewarding content that demonstrates deep expertise and genuine engagement with authoritative sources, but the goal is to be the authority, not merely a pointer to one. Every time you send a reader off to someone else's research, you're diluting the case that your site is the place to trust.
The balance to strike: cite sources when the credibility payoff is real, write those citations in a way that serves the reader, and then make sure the surrounding content is rich enough that there's no reason to leave.
So, to recap:
- Link to authoritative sources when it genuinely serves your reader, not to pad your content or signal credibility to an algorithm. And consider opening those links in a new tab; it's a small courtesy that keeps your site in the picture.
- Do it sparingly. The goal is to impress humans, not search engines or LLMs. If a link doesn't make your content meaningfully more useful to the person reading it, it doesn't belong there.
- Treat every outbound link as a missed opportunity. That link to the National Institute of Cat Health's study on feline obesity? That's an article you could write. Own the topic. Build the authority. Let other sites link to you.
GEO Content Implementation Checklist
Use this checklist when writing or auditing any piece of content for AI visibility:
- Demonstrate expertise directly. Does your content answer the question fully, without relying on outbound links to do the heavy lifting?
- Own the topic. For every external source you cite, ask: could we write that article ourselves? If yes, add it to your content roadmap.
- Write citations in plain language. Instead of a naked hyperlink, spell out the source and claim: "According to [Source], X is true." This is more useful to both readers and AI models.
- Link sparingly and intentionally. Every outbound link should pass the "does this genuinely serve the reader?" test. If not, cut it.
- Open outbound links in a new tab. A small but meaningful way to keep visitors on your site.
- Use structured formatting. Headers, tables, and clearly labeled sections help AI systems extract and attribute your content accurately.
- Include a definition block for key terms. If your content introduces or relies on specialist terminology (like GEO itself), define it explicitly near the top.
- Add a summary section. A brief bulleted summary — either at the top or bottom — dramatically improves how AI models parse and cite your content.
- Avoid hedging language. AI models favor content that makes clear, attributable claims. Vague, heavily qualified writing is less likely to be cited.
- Review for cart abandonment in your content funnel. Are there points where you're sending readers away before they've engaged with your core message or CTA?
