The AI Revolution in Search Marketing

The Rise of AI Chatbots

By Dave Taillefer, Business Director / ICONA

Back in 2023, the search landscape began to shift in a way we hadn’t seen since the early days of Google. The introduction of Google’s Search GPT Experience (SGE) and the rapid rise of conversational AI signaled the beginning of a new era—one where queries weren’t just answered, but interpreted. Powered by large language models (LLMs), AI chatbots started reshaping how users discover information and how marketers think about visibility.

Three early platforms defined that moment: OpenAI’s ChatGPT, Microsoft’s AI-infused Bing, and Google’s Bard. Each captured a different aspect of what conversational search could become.

ChatGPT set the tone. Its ability to produce human-like answers captured public imagination and reached 100 million active users faster than any platform in internet history. At a time when most search engines still served lists of links, ChatGPT offered something radically simple: a direct response.

Microsoft reacted quickly. Bing integrated GPT technology into its search engine, quietly becoming the first major platform to merge live search data with LLM-style reasoning. For the first time in years, Bing had the attention of both consumers and marketers.

Google’s Bard AI took a different route, built first on its LaMDA model and later moving toward the more powerful PaLM dataset. It marked the beginning of Google’s pivot toward AI-generated search experiences—an early signal of the direction SGE would eventually take.

And while Bing and ChatGPT shared the same GPT-4 backbone, they diverged in practice. Bing layered its model with real-time data. ChatGPT relied on a dataset capped in 2021, as noted in OpenAI’s documentation. The difference foreshadowed the next phase of search: accuracy, freshness, and authoritative sourcing.

User-Centric Approach in SGE

Among the early AI developments, Google’s Search GPT Experience (SGE) stood out for one reason: it was built around how people actually ask questions. SGE blended conversational context with traditional search, generating an AI snapshot designed to give users a fast, confident starting point.

Importantly, SGE wasn’t just a technical shift. It represented a behavioural one. Google introduced ad formats into AI-generated answers, turning search ads into something more dynamic—less like billboards, more like recommendations. Behind it all was an emphasis on quality, reliability, and strict compliance with Google’s policies for snippets and autocomplete. The message was clear: in an AI-driven environment, credibility matters more than volume.

Changing Landscape of SEO

For SEO, these developments marked a breaking point. Keyword-centric strategies were no longer enough. As chatbots began shaping how users receive information, the job of marketers shifted from optimizing for ranking positions to optimizing for comprehension—how well an AI system could understand, quote, or summarize the content.

This new reality required marketers to rethink everything from content structure to tone. Information needed to be clearer, more contextual, and written in a way that a conversational system could recognize and surface. It was the start of a broader transition toward AI-oriented visibility, long before the term “AEO” became mainstream.

Adapting to the AI Revolution in Search Marketing

The emergence of SGE and AI chatbots wasn’t just another trend—it reshaped what it means to compete for attention online. As AI tools matured, businesses and marketers had to adapt. Search became more conversational, more personalized, and more dependent on the quality of the underlying content.

Looking back, 2023 now feels like a hinge year—a moment when the future of search tilted away from lists of links and toward direct answers. And while the tools have evolved since then, the principle remains unchanged: firms that embrace conversational AI and structure their content for a new era of discovery will stay visible. Those who ignore it risk falling out of the conversation entirely.
