A lot has changed since I published Digital Marketing with Tortoise & Hare in 2017. Back then, the digital marketing conversation was heavily centered on websites, search rankings, social media consistency, and building momentum over time. Those principles still matter, but the landscape has shifted in a big way. Even the way people discover businesses and consume information has changed. My book was published on June 12, 2017, and in many ways, that feels like a different era of digital marketing. One of the newer terms getting a lot of attention right now is GEO , which stands for Generative Engine Optimization . If you’ve been hearing people throw that term around and wondering whether it’s just another buzzword, you’re not alone. But there is something real behind it, and it’s worth understanding. So, What Is GEO? GEO is essentially the practice of optimizing your business, website, and content so that AI-driven search experiences can find, understand, trust, and reference you. Traditional SEO has focused on helping your website rank in search engine results. GEO is more about helping your brand show up in AI-generated answers , summaries, recommendations, and citations. In simple terms: SEO helps you rank. GEO helps you get referenced. That’s a meaningful distinction. Today, people are no longer just typing a keyword into Google and clicking through ten blue links. More and more, they are asking full questions and receiving summarized answers from AI tools. That means your content is not only competing for rankings anymore. It is also competing to become part of the answer itself. Has SEO Been Replaced? No. Let me say that clearly: GEO does not replace SEO. It builds on it. If your website is poorly structured, your content is thin, your service pages are weak, and your business has little authority online, then GEO is not going to magically fix that. The same foundational principles still matter: a technically sound website strong service and location pages clear messaging helpful content consistent brand signals trust and authority In other words, the tortoise still matters. Steady, strategic digital marketing still wins over hype, shortcuts, and shiny-object syndrome. That hasn’t changed. What has changed is that now your content needs to be useful not just for human readers and search crawlers, but also for AI systems trying to summarize the web. Why GEO Matters If AI-powered search experiences continue to grow, businesses that are easiest to understand and trust will have an advantage. That means the question is no longer just: “How do I rank for this keyword?” It’s also: “How do I become the kind of source that AI tools want to cite, summarize, and recommend?” That changes the strategy. Businesses that win in this next phase will likely have content that is: clear direct well-structured specific trustworthy supported by real-world authority The businesses that struggle will often be the ones still publishing vague, bloated, keyword-stuffed content that says a lot without really answering anything.
