How is SEO changing in the age of AI and search evolution?
I have worked in SEO for 13 years, which in internet time feels like an entire era of human history. I have lived through the keyword stuffing days, the rise and fall of content farms, the dreaded Google updates that wiped out traffic overnight, and now the age of AI, where being cited and trusted matters more than simply ranking.
If you have been around SEO long enough, you will know it sometimes feels less like marketing and more like survival of the fittest. For years, the strongest species in the digital jungle were the ones who could stuff the most keywords into a page and collect the biggest pile of backlinks. Rankings were the only sign of life, and if you hit page one of Google, you were at the top of the food chain.
But like all ecosystems, SEO has evolved.Β
Google got smarter, users got fussier, and now AI has entered the scene like a whole new species, changing the environment completely. In this new world, simply ranking is no longer enough. To thrive, your brand needs to adapt, evolve and earn its place in the results chosen not just by Google but by AI engines such as ChatGPT, Gemini and Perplexity.
Here is how I have seen SEO evolve first-hand, from its caveman beginnings to the AI age.
Stage one: The caveman era, keyword hunters.
When I started in SEO, it really was as primitive as stone tools.Β
Success often meant repeating βcheap holidays Spainβ ten times in a single paragraph or cramming a footer full of city names to trick Google into thinking you were relevant everywhere.
I still remember optimising a page for a client where the keyword appeared in almost every sentence. It ranked well, but reading it back now makes me wince.
Backlinks were a free-for-all. I remember creating links from anywhere I could, even if the sites were more questionable than useful. The focus was on manipulating search engines, not helping humans.
It worked, but it was crude. Think cave paintings rather than fine art. And like cave paintings, it looked outdated almost as soon as it was finished.
Stage two: The farming era, content growers.
As Google matured, so did SEO.Β
This was the rise of content farming. I remember being part of projects where the aim was to publish as much as possible, as quickly as possible. 10 blog posts a week were seen as better than one well-thought-out article, because volume equalled visibility.
One site I worked on had hundreds of thin blog posts ranking. But after the 2011 Google Panda algorithm update, which demoted websites with low-quality content in order to improve user experience, its traffic dropped by more than 70% almost overnight.
The problem was obvious. Thin, low-value content could still rank. But then Google updates like Panda came along and ripped through those fields, felling the harvest overnight. I saw sites lose years of work in a single update.Β
It taught me a valuable lesson: SEO built on shaky foundations never lasts.
Stage three: The castle builders, authority seekers.
By the late 2010s, Googleβs expectations had shifted. It was no longer enough to have content; you needed authority. This was the stage where SEO started to feel more strategic.
I began focusing on building brands into trusted voices. That meant publishing case studies, producing genuinely useful content, and creating assets that others wanted to reference. E E A T became the framework: Experience, Expertise, Authoritativeness and Trustworthiness.
I still remember the relief of seeing sites I worked on survive algorithm storms because they were built like castles, strong and credible. Those who ignored authority were left exposed, while those who invested in it thrived.
Stage four: The AI age, adapt or go extinct.
Now we are in a brand new era.
AI has disrupted SEO in a way that feels less like gentle evolution and more like a meteor strike.
Users are not just searching Google anymore. They are asking AI engines for answers.Β
Tools like ChatGPT, Gemini and Perplexity decide in an instant which brands to cite and which to ignore. If your content is not being retrieved and trusted, you may as well be invisible.
This is where new evolutionary traits come in:
- Generative Engine Optimisation, GEO: Ensuring your brand is mentioned on AI platforms.
- Β Answer Engine Optimisation, AEO: Earning a place in Googleβs AI Overviews and answer boxes.
- Β AI Integration Optimisation, AIO: Structuring content so AI systems can understand and reference it.
- Search Experience Optimisation, SXO: Putting trust, design and conversions at the heart of SEO.
We are already seeing clients get cited in AI tools because their content is structured and evidence-based. This is the kind of visibility that compounds over time.
In the AI Age, it is not survival of the biggest or the loudest. It is survival of the most trusted.

How to evolve your SEO with the times.
Having seen SEO shift again and again, one thing has always been true. Adaptation is not optional.Β
Here is how businesses can evolve for SEO in the AI era instead of going extinct:
- Prove authority with evidence: Publish real case studies, original data and unique insights that AI can use as reliable citations.
- Structure content for humans and machines: Use clear headings, schema markup and connected content clusters.
- Focus on trust and experience: A site that looks sketchy or loads slowly is the digital equivalent of a sickly gazelle. It does not stand a chance.
- Go multi-platform: Do not stop at Google. The more you are mentioned in ChatGPT, Gemini and Perplexity, the more your authority compounds.
Survival of the smartest.
SEO has always been a moving target, and I have seen every stage of its evolution first-hand.Β
I started when keyword stuffing ruled the jungle, watched Google updates punish the weak, built authority in the age of castles, and now find myself helping brands adapt to the age of AI.
13 years in, the biggest lesson I have learned is that the businesses that embrace change are the ones that win. The ones who cling to old habits eventually disappear.
Rankings still matter in SEO, but they are no longer the only metric. The future belongs to those who adapt, evolve and build authority strong enough to be trusted by both humans and machines.
At Bamboo Nine, we help businesses not only survive this shift but thrive in it. We build authority that compounds over time, structure content for retrieval, and create user experiences that make brands memorable.
Because in the evolution of SEO, the adaptable do not just survive. They lead.
