SEO against the awareness funnel: how we kept growing an industrial brand that already owned its bottom-funnel keywords

Context

Healthy Air sells industrial air purification systems into commercial environments. Their strongest segment, by a wide margin, is nail salons. The volatile chemistry of acrylics, gels, and solvents makes ventilation a legitimate operational concern, and in many states it’s a legal one.

By the time we’d been working with them for a few quarters, the foundational SEO work was done and the bottom of the funnel was effectively won. Healthy Air ranked #1 or near it for the obvious buyer-intent keywords like “nail salon air purifier,” “nail salon ventilation system,” and the cluster of commercial-intent variants around them. Paid search was capturing what organic didn’t. Email was working. The numbers said the engagement was healthy.

This is the inflection point in most SEO programs where the strategy quietly breaks.

Constraint

The trap most agencies fall into when bottom-of-funnel is won looks like growth but isn’t. They go broader. They start chasing “air purification,” “commercial HVAC,” “indoor air quality” — big, high-volume, top-of-funnel terms with impressive search numbers. The reports look great. Traffic goes up. Then conversion rate craters, because the audience showing up to those queries isn’t shopping for what the client sells. Volume isn’t the same thing as qualified demand.

The mistake is treating SEO as a volume discipline when it should be treated as an awareness discipline. Eugene Schwartz’s awareness levels are the right map here — most-aware, product-aware, solution-aware, problem-aware, and unaware. Most SEO programs are built to catch most-aware and product-aware buyers, because those queries convert. That’s also why those queries cap out: the most-aware audience in any niche is the smallest layer of the pyramid.

Healthy Air had won the most-aware and product-aware layers in the nail salon vertical. The growth wasn’t going to come from doing that harder. It also wasn’t going to come from going broader as the audience searching “air purification” generically isn’t going to buy an industrial system designed for nail salons. The growth had to come from going earlier in the same niche. Down one layer to problem-aware: operators who knew they had a ventilation or compliance problem but hadn’t yet connected it to a product category. And eventually down further to solution-aware and unaware were the operators who hadn’t yet realized that the regulatory or air-quality issue existed at all.

Same buyer, earlier in their journey. Same niche, different awareness layer. That’s the move.

Move

We built a state-by-state nail salon ventilation code content cluster — the problem-aware layer made operational.

Nail salons in many states are subject to specific ventilation requirements to operate legally. Most operators don’t know the details of their state’s code until something forces them to find out which is usually an inspection, a build-out, an expansion, or a remodel. At that moment, the operator transitions from not thinking about ventilation to needing to understand it. They are now problem-aware. They are not yet product-aware. They are searching things like “nail salon ventilation requirements Florida” or “New York state nail salon ventilation code,” not “industrial air purifier.”

So we built the content that answers those searches. Pages for each state with ventilation requirements. Each page answered the regulatory question for that state in plain language, then created a natural bridge to the product solution Healthy Air offered. The structure mirrored the awareness ladder: arrive problem-aware, leave solution-aware, with a clear path to product-aware if and when the buyer was ready.

The Klaviyo state code capture was the nurture mechanism layered on top. Operators landing on the regulatory content could submit their email and get a tailored breakdown of their state’s specific requirements. The popup ran a 3.58% submit rate which is “Good” by Klaviyo’s own benchmark, which for a regulatory B2B context is meaningful. The capture didn’t drive direct revenue, and it wasn’t supposed to. No one reads their state’s ventilation code on Tuesday and orders an industrial purification system on Wednesday. These are operators who are usually building out or remodeling a salon, planning a new location, or working through inspection findings. The purchase cycle is months, not days. The point of the capture was to identify the buyer at the moment of problem-awareness and hold the relationship until they were ready to buy.

This is what makes SEO and email work together correctly. SEO catches the buyer at the awareness layer they’re currently in. Email walks them down to the next one. The state code cluster pulled in problem-aware buyers; the email sequence was meant to nurture them into solution-aware and then product-aware over the course of their build-out or remodel. The funnel is the awareness funnel, and SEO and email are the two halves of the engine that moves buyers through it.

Result

The most important number isn’t a revenue number. It’s a ranking number — because the strategic test was whether we could win in a new, earlier awareness layer the same way we’d already won at the bottom. That test we passed.

Healthy Air ranks #1 for “nail salon ventilation system requirements,” #1 for “nail salon ventilation requirements in Florida,” #1 for “nail salon requirements Florida,” and near the top for the New York equivalents. Keywords ranking 1-3 grew from 75 to 111 between 2024 and Q1 2025 — and the new positions sit almost entirely in the upstream regulatory cluster, not the bottom-funnel cluster we’d already saturated.

AOV grew from $915 to $1,079 between 2024 and Q1 2025. Some of that is mix shift, but the directional read is consistent with the strategy: buyers entering through a regulatory question tend to be operators planning a serious build, not consumers price-shopping for a single unit. The state code capture pulled 101 verified submits from 2,800 form views in the data window we have. While they are small absolute numbers, there is a very clear intent signal.

Revenue attribution from the cluster isn’t visible in a quarter, and that’s expected. Nail salon operators discovering their state’s ventilation requirements are usually in build-out or remodel mode. They’re collecting specs, comparing vendors, getting quotes, and routing the purchase through whoever’s running the project. The buying window for that cohort is months out from the moment they first searched the regulation. Asking the cluster to produce same-quarter revenue would have been asking it to do the wrong job.

What the cluster produced, on the timeline available, was the thing it was designed to produce: ranked authority in the right awareness layer, qualified traffic at meaningful submit rates, and a list of identified buyers sitting at problem-awareness waiting to be walked down to product-awareness.

What I’d do differently

The engagement ended before we got to truly see and refine the strategy.

What I’d do differently isn’t about the strategy itself. I’d run the same play again tomorrow. What I’d do differently is the case for renewal. The work we’d done by the time the engagement ended was the foundation of the awareness-funnel play, not the full execution of it. We’d built the problem-aware layer and proved it could rank and capture. What we failed to do was set expectations properly. No one was intended to convert this early in the funnel. That much our team knew, and assumed the client would as well. But slow results make for impatient clients.

The case I should have made more clearly: this isn’t a campaign. It’s a multi-year compounding asset. Every awareness layer we built would have fed the email sequence that walked buyers down to the next one, and every state added to the regulatory cluster would have widened the top of the funnel by a measurable increment. We were one or two layers into a strategy that wanted four or five, and we were doing it inside a niche the brand was already authoritative in, which is exactly the kind of compounding play that gets harder for competitors to catch the longer it runs.`

The strategy was right. The runway ran out before the compounding did.
