I’m reviewing the SEO & Internet Marketing Consultants industry in the U.S. and noticed the report doesn’t include detailed profit margin data. Do anyone know where I could find more in-depth financial data on this industry, or do you have any firsthand experience working in this space?

Jeremy, the industry reports will mostly lead you sideways on this. Variance within the category is huge and the public data is a couple years behind reality. Rough ranges I've seen: Solo operators and freelancers run 50-75% net margin but they're capacity-capped, so the absolute dollars don't get big. Small boutique agencies###-###-#### people) usually land somewhere in the 15-30% range, with most clustering at the low end because labor eats them. Mid-size agencies###-###-#### are often worse, 10-20%, because they've added overhead without proportional pricing power. Productized shops with repeatable processes and lighter labor are the outlier, 30-50% net, which is the model that's actually working right now. Three things drive most of the variance: business model (retainer vs project vs productized), overhead structure (employees vs contractors vs automation), and how much account management the relationships require. Account management cost is sneaky, it doesn't show up in financials cleanly but it's a huge margin driver in service businesses. The thing worth flagging if you're looking at this through an acquisition lens: all three of those are moving fast right now because of AI. Agencies that haven't adapted are watching margins compress as clients realize they can do a lot of the basic work in-house with AI tools. The ones that have adapted are seeing the opposite, because they've replaced labor cost with software cost. So an agency with clean 2024 financials might have a very different forward profile than a similar agency next door, and that won't be in the historical data. The diligence questions to surface this are different from the questions that surface reported margins. For context on where I'm coming from: about 6 years agency-side managing SEO and paid acquisition for ~150 ecommerce brands, then the last 5 years running digital growth in-house at a DTC business that scaled from $5M to $54M. So I've been on both sides of these P&Ls. On data sources, BizBuySell completed transactions filtered by NAICS###-###-#### will give you actual sale prices and SDE you can back margins out of. Quiet Light and FE International publish broker reports for digital service businesses with multiples and rough margin ranges. Borrell and Similarweb give you category-level revenue but not margin and I don't think Similarweb is really that accurate either. If you want to talk through it more, happy to. Especially if there's a specific target you're looking at.

Here is a draft that layers onto your previous comment naturally - as if you thought of one more thing worth adding: One more thing worth flagging on this - and this is more forward-looking than your immediate research question, but it feels relevant if you're evaluating this space seriously. The SEO industry is in the middle of a pretty significant disruption right now. A big chunk of traditional search traffic is shifting toward AI-generated answers - ChatGPT, Perplexity, Google's AI overviews. A lot of what these agencies have been selling for the last decade is built around Google ranking logic that is changing faster than most of their clients realize. The firms that are going to hold their value are the ones already repositioning around AI search optimization - getting clients cited in AI responses, structured data, content that answers questions the way AI pulls answers. The ones still selling the same keyword ranking packages from 2019 are going to have a harder time defending margins and retention over the next few years. Not saying it's a bad space to look at - just that if you're doing the research, it's worth asking any operator you talk to how they're thinking about that shift. The answer will tell you a lot about whether the business has legs.
