The rapid growth of AI-powered discovery tools like ChatGPT, Perplexity, and Google’s AI Overviews and Gemini, has everyone asking the same question:
“What does this mean for my website?”
Our recent blog on SEO vs GEO explored how businesses can improve their visibility within AI-powered search experiences and whether Generative Engine Optimisation (GEO) represents a genuine shift in strategy or simply a new label for existing SEO best practices.
But while marketers have been busy debating visibility, rankings, and citations, website owners have noticed a growing number of uninvited guests.
AI crawlers are visiting websites in increasing numbers, scanning pages, analysing content, and returning regularly for updates.
Most websites can accommodate this additional activity without issue. However, for larger sites or businesses operating on tighter hosting resources, the increase in crawler traffic can translate into higher server usage and additional infrastructure demands.
It’s not a cause for panic. It is, however, another sign that AI-powered search is becoming a bigger part of the digital landscape.
SO, WHAT IS AI BOT TRAFFIC?
If your analytics shows thousands of sessions with no engagement or conversions, you’re probably looking at crawler traffic, that has managed to sneak past GA4 filters. These are automated bots that scan your site but never behave like real customers.
Search engines have always used bots to explore websites and understand content. It’s how Google knows your latest blog exists before anyone’s searched for it.
The difference now is that we’re no longer dealing with just Googlebot.
Every AI platform wants access to the web’s information. To generate answers, recommendations, and summaries, they need to constantly discover and analyse content.
And that means more bots. More crawling. More requests hitting your server.
WHY IS IT INCREASING SO QUICKLY?
Because AI companies have a problem.
Users expect answers to be accurate, current and relevant. Nobody wants a chatbot confidently explaining a marketing trend from 2019.
To keep their responses fresh, AI systems need a constant supply of up-to-date information.
The result is a huge increase in crawling activity across the web as AI platforms repeatedly revisit websites looking for new content, updated information, and signals of authority.
In simple terms, the more people use AI search, the more AI platforms need to crawl websites.
And people are using AI search a lot.
HOW CAN AI BOTS IMPACT WEBSITE PERFORMANCE?
For many websites, the impact will be minimal. Modern hosting environments are typically designed to handle a reasonable level of crawler activity alongside normal visitor traffic.
However, larger websites, content-heavy publishers, and businesses with limited hosting resources may notice increased pressure on their infrastructure.
Potential impacts include:
- Higher server resource usage
- Increased hosting and cloud infrastructure costs
- Slower page response times during periods of heavy crawling
- Greater demand on website monitoring and maintenance
- Difficulty separating human traffic from bot activity in analytics
In some cases, businesses have reported AI crawlers generating a significant proportion of total website requests, particularly on websites with large archives of content.
DOES MORE AI BOT TRAFFIC MEAN BETTER VISIBILITY?
Not necessarily.
A lot of businesses assume that if AI bots are crawling their website, they must be appearing in AI-generated answers.
Unfortunately, it doesn’t work like that.
Being crawled simply means you’ve been considered.
Being cited means you’ve earned it.
AI platforms are increasingly looking for signals that marketers have been talking about for years: expertise, authority, trustworthiness and genuinely useful content.
So, even though the technology is evolving, good marketing is still good marketing.
SHOULD BUSINESSES BLOCK AI CRAWLERS?
This is a question many organisations are currently grappling with.
Some publishers and website owners have chosen to restrict certain AI crawlers due to concerns about content usage, intellectual property, or server costs. Others see AI platforms as an emerging source of visibility and are actively encouraging access.
There is no universal answer.
The right approach depends on your business goals, content strategy, and technical environment. However, before taking any action, organisations should understand exactly which bots are accessing their websites and what impact they are having.
Making decisions based on assumptions rather than data can result in missed opportunities or unintended consequences.
HOW TO PREPARE FOR AN AI-DRIVEN SEARCH LANDSCAPE
Rather than focusing solely on crawler activity, businesses should take a broader view of how AI is changing online discovery.
Key priorities include:
- Focusing on user experience with a fast-loading, accessible website.
- Regularly reviewing website performance, server resources, and crawl activity to ensure your infrastructure can handle increasing demand.
- Producing genuinely valuable content.
- Maintaining strong technical SEO to help both traditional search engines and AI systems access and understand your content.
- Understanding where and how your brand appears within AI-generated search experiences.
- Focusing on user experience with a fast-loading, accessible website.
THE BIGGER PICTURE
The increase in AI bot traffic is a symptom of a much larger shift taking place across the digital landscape.
As AI-powered search continues to grow, businesses should expect crawler activity to increase alongside it.
For some organisations, that may mean reviewing hosting infrastructure and monitoring server performance more closely.
For everyone else, it’s another reminder that visibility still starts with creating content worth discovering.
