How to Build a B2B Ads Funnel That Ends in a One-to-One Conversation
LinkedIn for TOFU, brand keywords and cross-platform remarketing on Meta and Google for MOFU, visitor identification and 1:1 outreach for BOFU.
By AthonBound Team
Most B2B ad budgets pay for a funnel and then wait for buyers to walk down it on their own. A better setup uses each platform for the job it's actually good at, and ends not with a form, but with a one-to-one conversation with the person who decides.
Quick answer: A B2B ads funnel that works runs on three layers connected by one list. TOFU: LinkedIn Ads, ideally video, on an audience you upload yourself, to put your name in front of the right companies. MOFU: brand and intent keywords on Google Search, plus cross-platform remarketing on Meta, LinkedIn and Google Display, so everyone who saw you keeps seeing you. BOFU: website visitor identification turns anonymous traffic into company names, and the decision-makers inside the companies that fit get a one-to-one message on LinkedIn and email. You stop waiting for buyers to convert on their own: the system tells you who they are.
The problem with the classic B2B funnel
The textbook version goes like this: awareness ads at the top, content and nurture in the middle, a demo request at the bottom. You pay at every step, and then you wait for the buyer to walk all the way down on their own.
Two things break it in B2B.
First, most of the people who engage never fill in a form. They watch the video, click through, read the landing page, and leave. You've paid for that attention and you have no idea who they were.
Second, each platform gets managed as its own silo. LinkedIn retargets LinkedIn traffic, Meta retargets Meta traffic, and nobody connects them. So the same buyer who visited your landing from a LinkedIn ad never sees you on Instagram, and the company that searched your brand on Google never gets a message from your team.
The fix isn't more budget or a longer funnel. It's a system where every platform does one job, and the data from all of them lands in one place.
TOFU: LinkedIn Ads, on a list you chose
LinkedIn is where you decide exactly who sees you. That's its job in the system: put your name and your point of view in front of the right companies before they're looking.
Use your own list, not just native filters. Upload the accounts and people you've already mapped. That way the same people receive your ads, your emails and your LinkedIn messages, and they find you everywhere.
Go wide on roles here. In outbound you write to the person who decides. On ads, the opposite works: reach the people who influence the decision too, for a bottom-up effect inside the account.
Video for reach, image for conversion. Video builds the audience you'll retarget. Image is what converts later.
Don't take the platform's suggestions at face value. Broad targeting is optimized to make you spend, not to make you convert. A campaign you set up yourself is much stronger.
Know what a meeting costs, not what you spend. If you're good, a qualified meeting from LinkedIn Ads costs around €300. Ten of them is €3,000 of spend that might bring €30,000. That's the right way to read the channel.
MOFU: brand, keywords and remarketing that crosses platforms
This is the layer most teams underbuild. Its job is to make sure nobody who saw you forgets you, and to catch the people who go looking.
Brand keywords on Google Search
People see your ad on LinkedIn, then go to Google and type your company name or your founder's name. If you're not bidding on your own brand, you paid to create that search and someone else collects it. Brand keywords are worth far more than they look.
Intent and comparison keywords
Separate campaigns for people searching the solution (intent) and people comparing options (comparison). Use exact match, with square brackets, never broad, so you don't pay for a word that happens to appear in an unrelated search. These are the same keywords worth targeting with SEO: if a query converts on paid, it's the first one to win organically.
Remarketing that belongs to the system, not the campaign
This is the shift that matters. Remarketing doesn't belong to the campaign that generated the visit. It belongs to everything.
Someone who lands on your page from LinkedIn becomes an audience for Meta. Someone who arrives from Google becomes an audience for LinkedIn. Someone who read your email and then visited the site becomes an audience for Google Display. The collection point is your website and landing pages, not the channel the visitor came from.
Where Meta fits
Meta is the same logic as LinkedIn with less precision and a lower cost. Its role here is remarketing and covering gaps.
| Meta setting | What to do |
|---|---|
| Audiences | Upload your CSV (it works even better on Meta than LinkedIn), and build a second audience from filters to recover the contacts the CSV doesn't match |
| Budget | At least €50 a day, below that you're not testing anything |
| Placements | Review them and remove the ones that don't convert. Automatic placements hide waste inside an acceptable average |
| Remarketing | Cross-platform: retarget on Meta the people who landed from LinkedIn, and the other way round |
Google Display, used properly
Display isn't for awareness. Use it to follow people who are already warm: your own remarketing audience, and people who've visited your competitors' pages. Almost nobody does the second one.

BOFU: from anonymous visitor to one-to-one conversation
This is where the system replaces the bottom of the funnel. The step-by-step deep dive is in how to identify the companies seeing your B2B ads.
1. Identify the companies. Website visitor identification on the landing pages and the whole site resolves anonymous traffic to the companies behind it, including the ones that never filled in anything.
2. Score them. Is this company in your ICP? If not, it stays in the remarketing audience. If yes, it moves forward.
3. Find the decision-maker. The person who clicked the ad might be an analyst. Find the person who signs.
4. Go one-to-one. A direct message on LinkedIn and a short email to that person, written about the problem your page addressed, not about the fact that they visited. On ads you declare the solution. In one-to-one outreach you surface the problem.
5. Keep feeding remarketing in parallel. At every step, the list for remarketing grows. Nothing is wasted.
When you know exactly who the decision-maker is, other options open too. A physical letter on their desk, for example: in 2026, a real envelope from someone who clearly knows their business stands out like nothing in their inbox.
The whole workflow on one page
| Stage | Platform | Job | What feeds the next stage |
|---|---|---|---|
| TOFU | LinkedIn Ads, video | Reach the right accounts on your own list | Video viewers, landing visitors |
| MOFU | Google Search, brand + intent | Catch people who go looking | Searchers, site visitors |
| MOFU | Meta, LinkedIn, Display remarketing | Stay in front of everyone who engaged, across platforms | Return visits |
| BOFU | Visitor identification + scoring | Turn traffic into named, qualified companies | Accounts in your ICP |
| BOFU | LinkedIn + email, one-to-one | Reach the decision-maker directly | Conversations |
The list is one. What changes is how much of it each platform receives and how you cut it.
Why this cuts the budget
For a company that spends heavily on ads, the effect is structural. You don't need to build a full TOFU, MOFU, BOFU content funnel and wait for buyers to reach the bottom alone. You jump straight to the decision-maker of every fitting company that engaged.
And you build your audiences knowing who's actually watching your creatives and landing on your pages, instead of guessing from the platform's segments. In our experience this can halve the budget needed for the same result.
What this needs underneath
None of this works as separate tools. It needs one data layer where visits, ad audiences, enrichment, scores and conversations meet, which is what an allbound GTM system is. For how inbound and outbound share that layer, see outbound and inbound for B2B.
We don't run your ads: that's a job for people who do it every day. We build the system around them, so the traffic they generate becomes accounts your team can work.
FAQ
What's the best ad platform for B2B?
There isn't one best platform, there's a job for each. LinkedIn for reaching chosen accounts, Google Search for people who are looking, Meta and Display for cost-efficient remarketing. They work best connected.
Should LinkedIn Ads be top of funnel or bottom?
In this setup, top. LinkedIn is where you control who sees you, so it's the right place to start the relationship. The bottom of the funnel is a one-to-one conversation, not another ad.
Do I need to bid on my own brand on Google?
Yes. People who see your ads elsewhere often search your name next. If you're not there, you've paid to create a search someone else captures.
Is Meta useful for B2B?
For remarketing and filling audience gaps, yes, at lower cost and lower precision than LinkedIn. Upload your list as CSV, add a filter-based audience, spend at least €50 a day, and prune placements.
How do I find out which companies click my ads?
With website visitor identification on your landing pages and site. It resolves a share of anonymous visits to company names, including people who never filled in a form.
How much does a B2B meeting cost from LinkedIn Ads?
If the campaign is well built, around €300 per qualified meeting. The question to ask is what that meeting is worth, not what the month cost.
