Display advertising has a reputation problem — and most of it is earned. Run it as a spray-and-pray awareness buy and it will happily spend your budget on accidental clicks, kids' tablet games and placements no buyer ever sees. Run it as a disciplined, placement-led performance channel and it becomes one of the cheapest ways to stay in front of in-market buyers.
This is the exact playbook we run for clients spending anywhere from $5k to $200k a month on display. Every step is about the same thing: only paying for impressions that can plausibly turn into revenue.
1. Start with placements, not audiences
Most advertisers start by picking an audience and letting the network choose placements. Invert that. Hand-pick 50–100 contextually relevant sites, apps and YouTube channels where your buyers actually spend time, and launch there first. Whitelist campaigns routinely beat open-network campaigns on cost per qualified visit by 30–50% in our accounts.
Review the placement report weekly for the first month. Exclude mobile game categories, parked domains and anything with a click-through rate above 2% but zero conversions — that signature almost always means accidental taps, not interest.
2. Layer intent on top of context
Once the whitelist performs, add intent layers: in-market segments, custom-intent keywords built from your competitors' URLs, and your own site-visitor lists. Each layer should be its own ad group with its own bid, so you can see exactly what an extra layer of intent is worth.
The sweet spot for most B2B and considered-purchase advertisers is contextual placement plus in-market intent. Broad demographic targeting alone almost never survives contact with the numbers.
3. Design creative for a 1.5-second glance
Display banners get about a second and a half of attention. One idea per banner, five words or fewer in the headline, a product or human face as the visual anchor, and a button-style CTA that states the outcome — "See pricing", "Get the audit", "Shop the sale".
Build every size that matters (300×250, 336×280, 728×90, 300×600, 320×50, 970×250) plus responsive display ads fed with distinct headlines and images. Accounts running 8+ creative variants per ad group consistently find winners that cut cost per conversion by a quarter or more.
4. Refresh creative before fatigue taxes you
Display creative fatigues faster than any other format because the same users see it repeatedly. Watch frequency and click-through rate by creative: when frequency passes 6–8 per user per month and CTR slides for two straight weeks, that creative is done.
Keep a simple rotation going — two new concepts a month, kill threshold set in advance (e.g. 2x target CPA with 25+ clicks and no conversion). Creative testing is the budget lever most display advertisers never pull.
5. Bid to a number, not a feeling
Give every display campaign a target: target CPA for lead gen, target ROAS for ecommerce. Start with maximise conversions to gather 30+ conversions, then switch to the target-based strategy with a cap 20% above your goal. Display algorithms need volume to learn — starving a campaign at $20 a day and judging it after a week tells you nothing.
6. Measure what display actually does
Last-click attribution will always undervalue display because it assists more than it closes. Track view-through conversions with a sane window (7 days, not 30), watch branded search lift in weeks display scales, and run geo holdouts twice a year: pause display in comparable regions and measure the difference in total revenue, not just display-attributed revenue.
Run this playbook for a quarter and display stops being a line item you defend and starts being a channel you scale. Want us to audit your placements? Our free ad audit finds the waste in your account within days.
