For UK B2B agency professionals and data brokers

The Hunter-Gatherer Gap

The only marketing split that doesn’t work is 100% gather, 0% hunt. Most UK B2B budgets are running it anyway.

Your clients running digital-only campaigns are your most exposed retainers. When the channel changes shape — as it is changing now — the pipelines they depend on thin first, and the conversation about agency value gets harder. Eight cards on the built-in risk inside your client book, and the standing recommendation that makes you the agency the client trusts.

About 20% of foragers ignore the waggle dance. That’s why the colony survives bad seasons.

When a scout bee finds a good patch of flowers, it returns to the hive and dances the direction. Most foragers follow the dance. About a fifth of the colony ignore it and fly off in random directions. The followers look efficient. The wanderers look wasteful — until the known flowers fail. The colony where every forager follows the dance starves when the patch is empty. Your clients’ marketing budgets run on the same logic — and most of them are running every forager on the dance.

The bee colony is the textbook example of the trade-off between working what you have and looking for what’s next. Ad guru Rory Sutherland often references the work by Viswanathan (Nature 1999) on Lévy-flight search and Seeley on honey-bee scout / recruit ratios — both find that healthy colonies keep a steady minority of scouts at all times. March (1991) showed the same logic for organisations: a company that puts everything into working what it has hits the best version of where it is, and can’t find anywhere better. For agencies, the relevance is in the client book — the clients whose marketing budgets are all gather are the clients carrying built-in channel risk on your behalf.

Most of your clients’ marketing budgets are 100% gather, 0% hunt.

Gathering is the digital playbook your team delivers brilliantly — Google Ads, LinkedIn, SEO, retargeting, content. Reliable, measurable, defensible. Most of any client’s budget belongs there. The problem is “most” has become “all” for most B2B clients, and the hunter’s allocation — reaching out to named decision-makers the client’s dashboard doesn’t know — has quietly disappeared from most plans. The only split that doesn’t work is the one most B2B clients are running.

If you’ve played MMORPGs, you’ll know the grinding-vs-exploring trade-off. Grinding the known map is reliable. The next big find is somewhere you haven’t walked yet. Same trade-off, same trap when you skip the explore loop.

See the evidence

The pattern is consistent across UK B2B channel-mix surveys: digital channels take most of the marketing budget because they are measurable, defensible, and reliable. They are the gatherer’s mix and they belong there. The risk agencies carry is that their clients’ whole budgets sit on channels owned and run by middlemen whose interests are moving away from the advertiser’s. When the channel changes shape — as AI Overviews are doing now — a 100% gather budget has nowhere to go, and the call to the agency starts with “why isn’t the pipeline working?” rather than “what should we add?” The steady minority allocation to hunting is the position the colony has held for thirty million years; the marketing equivalent has been a footnote in client plans for the past five.

Working the known channels harder produces less, not more — once the channel has changed shape.

Your clients’ digital playbook is delivering less per pound than it was. The previous Corpdata briefing set out the diagnosis — AI Overviews now answer most B2B information queries; HubSpot reports a 70% drop in organic traffic across its hosted sites; UK B2B paid acquisition cost is up 24-29% year on year. The pipelines your clients depend on are thinning, and your retainer is the conversation they reach for first when they do. The 95% of buyers who aren’t in market this week never see those ads — they only see the businesses that come to them.

The maths on the gatherer’s mix has flipped over the past two years. BrightEdge data shows 91% of B2B information searches now trigger an AI Overview — the answer appears at the top of the page and the reader leaves before reaching any website. HubSpot, the largest B2B content-marketing publisher in the world, has reported around a 70% drop in organic traffic to its hosted sites between 2024 and 2025. UK B2B paid acquisition costs have been climbing 24-29% year on year. Per the 95:5 rule from the Ehrenberg-Bass Institute, the 95% of B2B buyers who aren’t actively in market never see those ads in the first place — they build their shortlist from the businesses that come to them. The result for agencies: clients whose whole spend is in the gatherer’s mix are clients whose pipelines move with the algorithm.

A letter, a call, a named-recipient email — they signal something a banner ad cannot.

The buyer can see the work. A named letter that arrives on their desk took real effort to send. So did a phone call. So did a personalised email. The effort itself is the signal — it tells the buyer the business chose them on purpose. A banner ad signals the opposite: that the advertiser bought a slot on a list of people who fit a profile. For the agency, this is the differentiator that’s missing from most client decks — the channel that signals value because the recipient sees the work.

If gold-rush imagery lands better than bee colonies, call it prospecting versus mining. Mining is taking value from a known seam — reliable while it lasts. Prospecting is going to look for new ground. You need both. Most UK B2B client plans are all mine and no prospect.

A named letter, a personal email or a phone call all take effort the recipient can see: a real address, a real name, a real timing decision. That effort says “we chose you” — what Spence (Nobel, 2001) called a costly signal. A banner ad says the opposite: that the advertiser bought a slot on a list of people who fit a profile. The Direct Marketing Association’s UK response benchmarks show the gap on like-for-like methods: direct mail at 4.4%, email at 0.12%, display advertising at 0.04%. Direct mail in particular keeps around a 90% open rate. For agencies, the point is that direct access is the standing differentiator in a market crowded with digital-first specialists — the channel the agency can run on behalf of clients that the client cannot easily source elsewhere.

Most clients already know this. What’s missing isn’t the opinion — it’s the words.

If you’ve read this far, the argument isn’t new to your client either. They can feel the digital playbook is producing less. They can see the AI Overviews on their own search results. What’s missing in the client conversation isn’t a different opinion — it’s the words to act on the one they already half-hold. The agency that brings the words to the next client review is the agency the client trusts. The hunter’s allocation is the words. Direct access is the channel.

See the evidence

Pfeffer & Sutton (2000) called this the knowing-doing gap: companies regularly know what they should do and fail to do it, not because the diagnosis is unclear but because acting means changing a budget, changing a reporting line, or starting a conversation no-one wants to start. The IPA / FT Board-Brand Rift study found that 83% of business leaders believe marketing contributes to the bottom line — but more than half rate their own knowledge of brand-building as average or poor. The board votes on gut feel because nothing else is in front of them. The agency’s job in the next client review isn’t to argue against client conviction — it’s to put the words in front of clients who already half-agree but have nothing on paper. The agency that does this consistently is the agency that holds onto clients when the channels shift under them.

Your most digital-only clients are your most exposed clients.

When a client’s pipeline depends entirely on the channels the previous Corpdata briefing diagnosed, the risk you’re carrying for them is built in. The clients running 100% gather are the clients whose pipelines move with the algorithm. When those pipelines thin — as they are thinning now — your retainer is the first conversation they reach for. The clients running a hunter’s allocation alongside their digital mix are the ones whose pipelines hold steady. Their conversations with you stay strategic. The all-gather clients’ conversations turn defensive.

07

The agency a client trusts most is the one who tells them what they’re missing.

A trusted agency isn’t the one that keeps the client comfortable. It’s the one that walks into a review and says “the channels we run for you are working — and there is a channel we don’t run that we should add.” The hunter’s allocation belongs in your standing recommendation, alongside the digital mix you already deliver. Bringing it before the client asks for it makes you the strategic partner, not the channel-delivery vendor. The argument lands more easily when the agency is the one bringing it — not the client’s CFO, and not a competing pitch.

08

Direct access for your clients — verified named contacts, your standing recommendation.

The hunter’s allocation needs a way to reach customers that doesn’t go through Google or LinkedIn. Direct access is that way: a verified named list of the UK decision-makers your client wants as customers, reachable by post, email or phone. Corpdata supplies the data; the agency designs and runs the programme. No platform auction, no algorithmic black box. One pound, one contact — pricing is simple and yours to set. The differentiator your client has been missing is the one you can add to the standing recommendation this quarter.
