Will SEO be replaced by AI?
Google's AI Overviews and ChatGPT/Perplexity have compressed the top-of-SERP results and eaten some navigational and informational traffic. But the underlying demand (people searching for products, services, and answers) hasn't disappeared, just fragmented. SEO is shifting toward ranking IN AI answers (which cite sources), toward brand and entity signals, and toward high-intent commercial queries where a click still matters. The category is changing, not dying.
How big the AI side actually is
Not on the current numbers. The Wall holds 105 US listings filed under AI Marketing as their primary discipline, against 265 filed under SEO. On the service field the gap is wider: 33 listings name AI consulting while 551 name search engine optimization.
The AI cohort is young, with a median founding year of 2019 and 32 of them founded in 2020 or later. It is growing from a small base rather than absorbing the incumbent discipline.
The AI firms are also not undercutting anybody. 71 of them publish an hourly rate and 63 sit between $100 and $199, while 17 of the 71 that publish a minimum require $25,000 or more. This is being sold as expensive consulting, not as a cheaper replacement.
How to use this
Treat AI as a change to how the work gets done rather than to who gets paid for it. Ask a prospective firm what it has automated and what it still does by hand. The honest answers are more specific than the marketing.
How this was computed. Every figure on this page is counted from The Wall's own directory of approved, US-headquartered, machine-verified-live listings: 3,460 of them in the snapshot captured 2026-09-14. Rates, minimum project sizes, team sizes, founding years and ratings are provider-declared figures published on public profiles. 1,738 of those listings publish a service list, and that field holds at most 4 services per firm, so service counts are counts of what firms name first rather than everything they sell. Percentages of disclosed values exclude listings that publish no figure. Nothing here is modeled or estimated. Sourcing standards: editorial policy.
Why this matters
Google puts this question in People Also Ask for the "seo agency" query, which means buyers are asking it while they shop. The Wall answers it from the directory position: we index 3,460 verified US growth-services vendors across 10 pillars, so the figures above come from those records rather than from a survey.
If you are evaluating vendors in this category, the SEO pillar page carries the full US firm list with rate, team size and headquarters filters.
