SEO Demand Surges Amid the Rise of AI Search (2015–2025 Trends)

The demand for search engine optimiation (SEO) expertise is higher than ever in 2025, reaching record levels in terms of search interest and query volume. This surge comes even as new AI-driven search tools (like chatbots and generative search results) emerge. Contrary to early predictions that AI would diminish SEO. In fact, SEO interest has grown alongside these AI trends, indicating that businesses and marketers are seeking guidance on how to adapt SEO strategies in the age of AI search. Traditional search remains dominant (Google processes 14 billion searches per day vs. only 37 million daily queries on ChatGPT), so optimising for search engines is still crucial. Below, we examine SEO search trends in the UK and US, and how the rise of AI search is impacting SEO demand.

United Kingdom: SEO Interest Hits All-Time Highs

In the UK, interest in SEO has steadily grown over the past decade and skyrocketed to new highs in 2025. Both Google Trends data and Ahrefs search volume estimates confirm this growth:

• Long-Term Growth: Monthly Google searches for “SEO” in the UK climbed from roughly 27,000 in late 2015 to about 66,000 by mid-2025 – over a 140% increase. This long-term rise reflects the increasing importance of SEO skills and services.
• Pandemic-Era Spike: Notably, interest spiked in early 2020. Search volume nearly doubled from ~36k in December 2019 to over 71k in January 2020 as businesses rushed online during the COVID-19 lockdowns. This period marked a surge of new websites and digital initiatives, driving more searches for SEO help.
• Record Peak in 2025: SEO interest hit unprecedented levels by 2025. According to Google Trends, the relative interest in “SEO” reached an index of 100 (peak popularity) in the first week of June 2025 – the highest point in the last decade. This peak coincided with growing discussion of AI-powered search changes, suggesting that news about tools like Google’s AI search updates fueled greater curiosity about SEO. Even within the Business category alone, “SEO” reached peak interest at this time in the UK. In short, UK marketers are searching for SEO guidance now more than ever.

United States: Similar Surge in SEO Queries

The United States shows a parallel trend of rising SEO interest, on an even larger scale. U.S. search volumes for SEO-related queries have grown dramatically from 2015 to 2025:

• Massive Growth in Volume: Monthly searches for “SEO” in the US grew from around 91,000 in late 2015 to well over 500,000 at the peak in May 2025. This is roughly a 5–6× increase in search demand. The climb was gradual at first but accelerated in recent years.
• 2020 Uptick: Similar to the UK, the US saw an uptick in early 2020 as businesses invested in online presence. By January 2020, U.S. SEO queries jumped to ~199k (from ~109k in late 2019), reflecting heightened interest during the onset of the pandemic. This momentum continued as digital marketing became a lifeline for many companies.
• 2023–2025 Resurgence: After some fluctuations, interest surged sharply in 2023–2025. Ahrefs data shows U.S. search volume for “SEO” peaking at 533,000 in May 2025. This aligns with the timing of generative AI search features rolling out (e.g. Google’s SGE/AI overviews in 2024–25), which prompted many to seek out SEO strategies for the new landscape. In Google Trends, global interest roughly doubled from an index ~45 in late 2024 to 100 by mid-2025, and U.S. marketers were a big part of that wave. The data makes it clear that far from fading, SEO is top of mind for a growing number of businesses in the U.S.

The AI Search Effect: Why SEO Demand Is Growing

Does the rise of AI in search mean the end of SEO? Thus far, the answer from the data is a resounding no. In fact, AI-driven search changes appear to be fueling more interest in SEO rather than less. Here are key insights on how new AI search trends are impacting SEO demand:

• AI Hype vs Reality: Early predictions claimed that AI chatbots and answer engines would kill traditional search (and by extension, SEO). However, reality indicates otherwise. As of 2025, Google’s search traffic still dwarfs that of AI chat tools – on the order of hundreds of times largercontentful.com. One industry analysis noted that AI search generates over 90% less traffic than traditional search engines – chatbots send 96% less traffic than Google search. The vast majority of users continue to rely on search engines, meaning SEO remains as relevant as ever for visibility.
• SEO Adapting, Not Dying: Rather than replacing SEO, generative AI is expanding the field of SEO into new areas. As one SEO expert put it, “AI isn’t replacing SEO. It’s expanding SEO into new territories with bigger opportunities.”. Marketers are learning to optimise content not just for classic blue-link rankings, but also for featured snippets, AI-generated answers, and voice results. This has actually broadened the scope of SEO, and the surge in “SEO” searches suggests many are seeking guidance on these new optimisation challenges.
• New Terms, Minimal Interest: Within marketing circles, terms like Answer Engine Optimisation (AEO) and Generative Experience Optimisation (GEO) have emerged to describe optimiing for AI answers and generative results. However, these buzzwords have microscopic search interest compared to plain “SEO.” General audiences aren’t searching for “AEO” or “GEO” en masse, indicating that most businesses see AI-related search issues as part of the SEO domain, rather than a separate discipline. The focus for most remains on core SEO practices, even as they adapt them to the AI era.
• SEO Demand at Record High: Ultimately, the advent of AI in search has prompted a renewed focus on SEO. Companies want to ensure their content is the one being cited by AI answers and still ranking in traditional results. This is evident in the record-high Google Trends scores and search volumes for SEO in 2025. Marketers are actively researching how to maintain visibility; whether through technical SEO, content optimisation for featured snippets, or ensuring brand presence in AI-driven answers. In short, AI has not reduced interest in optimisation; it has heightened it.

Key Takeaways

• SEO interest is surging, not declining: Both the UK and US have seen all-time high interest in SEO in 2025, as measured by Google Trends and search volumes. This contradicts the notion that AI would make SEO obsolete – instead, SEO is more in-demand as the digital landscape evolves.
• External shocks spur SEO growth: Periods of disruption like the COVID-19 pandemic and the introduction of AI search features triggered spikes in SEO queries. Businesses respond to these disruptions by seeking SEO expertise (e.g., the doubling of UK SEO searches in Jan 2020 and the global peak in mid-2025 amid AI search rollouts).
• AI search is not replacing traditional search: Traditional search engines still dominate how people find information, by orders of magnitudecontentful.com. AI chat tools, while growing, are a supplement. Thus, SEO remains crucial for reaching the vast majority of searchers. Traffic from AI “answer engines” is still only a trickle relative to Google.
• SEO is evolving (AEO, GEO) but fundamentals remain: Optimising for AI-driven results (AEO/GEO) is essentially an extension of SEO. Few are specifically searching those new acronyms – instead, they’re looking up SEO strategies for the AI era. The core principles of creating authoritative, crawlable, user-friendly content are still key, even as we tweak tactics for featured snippets or AI answers.

In conclusion, the rise of AI in search has heightened the need for SEO rather than diminished it. Both data and industry sentiment show that SEO is alive and kicking – adapting to new challenges and more sought-after than ever. Businesses in the UK, US, and globally are investing in SEO knowledge to navigate an era where search engines and AI answers coexist. Far from being replaced, SEO is evolving and growing as an indispensable practice in the age of AI-driven search.
