Evergreen Growth & Marketing - B2B LinkedIn Ads Agency

    B2B event marketing strategy for exhibitors, 2026

    Your stand lasts three days. The pipeline from it should last a year.

    You've paid for the stand, the flights, the hotel and a week of your best people's time. Here's how to use LinkedIn Ads before, during and after the show so the right companies know you before you arrive and remember you long after you've packed up.

    The short answer

    B2B event marketing works best when the show is the middle of the campaign, not the whole of it. Build a list of the companies you want, reach their buying committee on LinkedIn before the doors open, capture what buyers say on the day, then keep showing up to those same companies for the next 12 months.

    Start where you are

    The problem

    Three days out of 365

    Most exhibitors spend months planning a show and a few days following it up. Here's what the year looks like when the show is the only time buyers see you.

    A year of visibility with a target account

    JanuaryThe showDecember
    Warm-up advertsThe showFollow-up adverts all year

    Top bar: you exist for three days. Bottom bar: the same show, but the companies you care about see you every week. When one of them starts looking for a supplier in month seven, you're the name they already know.

    And B2B deals are rarely decided by the person who stopped at your stand. They report back to four or five colleagues who never met you. Unless something reaches those colleagues, you start the buying process as a stranger.

    Before the event

    Arrive already known

    The goal isn't to reach every attendee. It's to make the small group of companies who could genuinely buy recognise your name, your people and the problem you solve before they walk past your stand.

    Step 1: Build the list from companies you can name

    Stack these four groups into one spreadsheet of company names. This becomes your LinkedIn audience.

    Current customers

    Protect them. Competitors are at the same show.

    Open and lapsed opportunities

    The deals that went quiet. The show is your excuse to reappear.

    Dream accounts

    The 50 to 200 companies you'd most like to win.

    Filtered exhibitor and visitor companies

    The public list, minus everyone who can't buy from you.

    Not sure who belongs on it? The free account list builder gives you 50 named companies and the search strings to find more.

    Step 2: Add the people who actually decide

    On LinkedIn you can narrow each company down by job title. So instead of reaching 400 staff at a food manufacturer, you reach the handful who sign off a purchase like yours.

    Operations or technical leadFinance directorProcurementManaging directorThe team who'll use it

    Two settings that matter

    LinkedIn needs at least 300 matched members before an ad will run, so a list of 20 companies with narrow titles may be too small. Add more companies or more relevant titles rather than broadening. And switch off Audience Expansion, or LinkedIn will quietly show your ads to people outside your list.

    Step 3: Give them a reason to find you

    What most exhibitors post

    "We're excited to be exhibiting at Packaging Innovations 2026. Come and see us on stand B47!"

    What gets noticed

    "Every year at this show someone asks me why their changeovers take 40 minutes. Bring your line spec to B47 and I'll show you where the time goes. Takes ten minutes."

    Post it from the founder, engineer or consultant who'll be on the stand. Then put budget behind the post as a Thought Leader Ad so it reaches your list. It looks like a normal post in the feed, from a real person.

    A real person, a specific event and one useful point. No production crew needed.

    If the show is next week

    Do three things. Skip everything else.

    1. 1Upload your customers, open opportunities and 50 dream accounts as one company list.
    2. 2Write one post from the person going: the problem you'll be talking about and a reason to stop by.
    3. 3Boost it as a Thought Leader Ad to that list, with decision-maker job titles, from now until the last day of the show.

    During the event

    Capture what buyers say, not what your brochure says

    For three days your target market is walking up and telling you, in their own words, what they worry about. Almost every exhibitor lets that disappear. Capture four things and you have months of adverts.

    The questions buyers ask

    Write down the exact words. "Does it work with our old line?" is a better advert headline than anything your agency will write.

    You need: A notes app, one list per day

    Short vox pops

    One question your market genuinely argues about. Ten to twenty answers. Get written or recorded permission before you publish.

    You need: A phone and a clip-on mic

    The bit people stop to look at

    Film the 30 seconds of demo where visitors lean in. Not a tour of the stand. Not the logo wall.

    You need: Phone on a small tripod

    Founder observations

    What surprised you, what everyone disagreed about, what nobody is talking about. Posted from a real person, not the company page.

    You need: Two minutes at the end of each day

    A daily routine that takes 20 minutes

    Before doors openPost one observation or question from the founder. Put £20 to £50 behind it, aimed only at your company list.
    MiddayFilm two or three answers to your vox pop question. Note every question visitors asked in the morning.
    End of the dayPick the best clip or photo. Write down who you met by company, not just by name. Upload new badge scans.

    Keep the audience fixed to your company list. The point isn't viral reach. It's that the people who matter see your team in the middle of the conversation while they're at the same show.

    After the event

    The 12-month follow-up

    The usual follow-up is one email to every badge scan. A few reply. The rest go quiet, and a year later you pay to stand in the same hall and meet them again. Here's the alternative.

    1. First 48 hours

      Send what you promised, person by person. Group every contact, note and scan by company. Upload scans as a LinkedIn contact list.

    2. Weeks 1 to 4

      Show the whole buying committee at each company who you are: the founder's posts, the vox pops, the demo. Recognition, not a pitch.

    3. Months 2 to 6

      Move to proof. Customer stories, how it works, the awkward questions answered, an advertorial on the problem you solve.

    4. Months 6 to 12

      Stay present while budgets get set. Retarget anyone who watched or visited. Direct messages to the most engaged accounts. Book the next show.

    Tell sales which companies are warming up

    LinkedIn's Company Engagement report shows which companies on your list are seeing and interacting with your adverts. Combine that with who you met and who's visiting your website, and sales know who to call first.

    Engagement is a reason to get in touch, not proof someone wants to buy. Treat it as context for a useful conversation.

    Content

    Two event assets people actually remember

    Vox pops built on one question

    Ask one question your market genuinely argues about. Keep the clips short, caption them and let buyers hear their peers say it. People trust the person next to them in the hall far more than they trust you.

    One sharp question can give you ten clips and a better sales conversation.

    A leave-behind worth keeping

    Swap the glossy brochure for something that helps: a benchmark, a checklist, a short report on the problem they came to solve. For your top ten accounts, make a version with their name on it.

    Didn't film anything? You can still make most of this afterwards. The founder can talk to camera about what buyers asked, and the leave-behind works just as well sent by post. Free tools to help: the video script generator and the anti-ad builder.

    Money

    What to spend

    There's no honest universal number, but there is a sensible way to think about it.

    Start with the event cost

    Add up the stand, travel, hotels, staff time and print. That's what you've already invested in these companies.

    Spread a slice across the year

    A small monthly LinkedIn budget aimed at a precise list often costs far less than the stand itself.

    Check the floor

    LinkedIn's minimum is around £10 a day per campaign. Small lists spend less than you'd expect.

    Use the free Trade Show ROI Calculator to plug in your own event costs and results. It won't promise a made-up multiplier. It shows what the event is costing you per conversation and what a year of follow-up would add. You can also check realistic spend with the LinkedIn budget calculator.

    Avoid these

    Seven mistakes exhibitors make with LinkedIn

    "Visit us at stand 47" as the whole advert

    Nobody books a flight because of a stand number. Give them a reason: a question answered, a demo, a person worth meeting.

    Targeting everyone at the show

    Most attendees can't buy from you. Build the audience from named companies and the job titles that decide.

    Leaving LinkedIn Audience Expansion switched on

    It lets LinkedIn show your ads outside your list. Switch it off for every event campaign.

    One follow-up email, then silence

    The person you met reports back to four or five colleagues who never saw you. Reach them too.

    Running the event recap for months

    "Great to see you at the show" is stale after three weeks. Move on to proof and objections.

    Sending ad clicks to the homepage

    Send them to a page that carries on the same conversation and makes booking easy.

    Judging it on badge scans

    Scans measure footfall. Judge it on meetings, opportunities and deals from target accounts.

    What to measure

    Badge scans flatter a bad event. For niche B2B, judge it on the companies and buying groups behind the activity.

    B2B event marketing FAQs

    Can LinkedIn advertising still help if the event is next week?

    Yes. Use one strong personal post, a tightly defined company and job-title audience and a clear reason to speak at the event. Don't try to build a complicated funnel in five days.

    What if the event has already finished?

    Start with the companies and people you met, the pages they visited and any content you captured. If you captured nothing, you can still film the founder talking about what buyers asked. Read the guide to LinkedIn Ads after a trade show for the full 12-month plan.

    Should we target every attendee?

    No. Most niche B2B firms should target the companies and buying roles that can genuinely buy. Precision matters more than the organiser's headline attendance figure.

    How long should post-event advertising run?

    For a long B2B buying cycle, think in months, not weeks. Keep it running while the audience is still worth reaching and change the message as the event becomes less relevant.

    Should LinkedIn Audience Expansion be enabled?

    No. For named-account event campaigns it weakens the point of the list by allowing delivery beyond the audience you chose.

    What should the first pre-event advert say?

    Lead with a useful opinion, demonstration or buyer problem connected to the event. Treat the stand number as supporting information, not the whole message.

    Do we need professional event video?

    No. Clear sound, a steady frame and a useful point matter more than production. A candid clip from the right expert is often more believable than a polished montage.

    Can we use the exhibitor list for targeting?

    Use the public list as a research starting point, remove companies outside your market and add the buying roles you need. Follow the organiser's terms and data rules.

    What is a qualified event conversation?

    Define it before the event. Normally: a relevant company, a plausible buyer, a real problem and an agreed reason to keep talking.

    How should sales use LinkedIn engagement after the event?

    As context, not proof that someone wants to buy. Prioritise accounts showing several signals and approach them with the useful follow-up you promised.

    What's the minimum LinkedIn budget for an event campaign?

    LinkedIn's minimum is around £10 a day per campaign. For a small company list, a few hundred pounds a month can keep you visible. Use the Trade Show Amplification Planner to work out a figure from your own event costs.

    What if our LinkedIn audience is very small?

    LinkedIn needs at least 300 matched members to run an ad. Build from named companies, add every relevant job title and combine related groups. Don't pad it with irrelevant companies.

    Can event content be reused later?

    Yes, if it still answers a buyer question. Remove dated references and turn the best material into posts, clips, guides, sales follow-up and retargeting adverts.

    How do we connect the event to revenue?

    Record the company, people, conversation and next step in the CRM, then track opportunities and customers over the normal sales cycle. Keep influenced pipeline separate from won revenue.

    Can Evergreen run this for us?

    Yes. We build the company list and audiences, make the adverts with you, run the campaigns and report which accounts are warming up. Book a call with your next or last event in mind.
