What frequency caps should we set on B2B retargeting?

Frequency is the single biggest lever in B2B retargeting. We cap high-intent audiences at 8 to 12 impressions per user per week with a 30 to 45 day decay window. Mid-intent runs at 4 to 6 impressions per week with a 60 day window. Low-intent caps at 2 to 3 per week across 90 days. Long retargeting windows quietly destroy brand sentiment. A buyer who spent four minutes on your site eight weeks ago does not need to see your demo ad today, but they will if you let the platforms decide.

Should we segment retargeting audiences by intent?

Yes. The single audience approach (everyone who visited in the last 90 days) is the most common mistake we see. It conflates a buyer who read a blog post once with a buyer who hit pricing three times in a week. We split into high-intent (pricing, demo, contact pages in 30 days), mid-intent (service or comparison pages in 60 days) and low-intent (blog content only, 90 days). Each segment gets different creative, different frequency and different offers. Existing customers go on a suppression list.

Why does our retargeting look great in reports but not produce pipeline?

Last-click attribution flatters retargeting badly. Almost any return-path conversion appears to come from retargeting under last-click, regardless of whether retargeting actually moved the buyer or simply intercepted a return visit. We test retargeting against view-through conversions with a sensible 1 to 7 day window (not 30), incrementality testing through geo or audience holdouts where spend justifies it, and multi-touch attribution that gives credit beyond last-click. If retargeting metrics look strong but sales sees no lift, it is intercepting rather than influencing.

Retargeting tech buyers without burning the brand

Retargeting is the channel B2B tech advertisers most commonly mismanage. The default state of most accounts is a single retargeting audience (anyone who visited the site in the last 90 days), a single piece of creative (a generic demo invite) and a frequency cap that stops at “however much LinkedIn or Google decides”. The result is the ad that follows a buyer for three months after they spent two minutes reading a blog post, and the buyer associating your brand with stalking rather than relevance.

Retargeting can do real work for B2B tech, but it has to be structured. Below is how we run it, and what we change first when we take over an account that is over-serving its existing audience.

What retargeting is actually for

Retargeting is not a lead-gen channel. It is a conversion channel that harvests demand created elsewhere. The mistake we see is treating retargeting as the place pipeline gets generated. It is the place pipeline gets accelerated, sometimes meaningfully, but only against an audience that the demand-gen layer has already warmed.

Two practical implications follow.

First, retargeting performance depends on the quality of the audience feeding it. A site that gets traffic from broad-match Google Ads chasing “what is” queries will have a poor retargeting pool because most of those visitors were not buyers. A site that gets traffic from carefully targeted LinkedIn Ads and intent-driven search will have a strong pool.

Second, retargeting budgets should be sized to the audience, not to the spend. Throwing more budget at a 5,000-person retargeting pool just inflates frequency. Better to grow the pool first, then scale the spend.

Audience segmentation that does not collapse on itself

The single audience approach (everyone who ever visited the site in the last 90 days) is the most common mistake we see. It conflates a buyer who read a blog post once with a buyer who hit the pricing page three times in a week. The two need very different creative and very different frequency.

The segmentation we usually build on a B2B tech site:

Segment	Audience definition	Creative direction
High-intent	Visited pricing, demo or contact page in last 30 days	Direct conversion offer
Mid-intent	Visited service pages or comparison content in last 60 days	Case study, comparison, peer call invite
Low-intent	Read blog content only, no service-page visits, last 90 days	Brand awareness, value content
Customer / current client	Existing CRM contact match	Excluded from prospect retargeting; runs in upsell layer if relevant

The customer exclusion matters. Few things irritate buyers more than seeing a “book a demo” ad three weeks after they have bought. The CRM-based suppression list is the cheapest performance gain on most accounts.

Frequency caps and decay

Frequency is the single biggest lever in B2B retargeting. Too low and the audience never registers the message. Too high and the brand experience tips into irritation.

Our defaults, varied by audience and platform:

High-intent retargeting: cap at 8 to 12 impressions per user per week, decay window 30 to 45 days
Mid-intent retargeting: cap at 4 to 6 per week, decay window 60 days
Low-intent retargeting: cap at 2 to 3 per week, decay window 90 days

The decay window matters because long retargeting windows quietly destroy brand sentiment. A buyer who spent four minutes on your site eight weeks ago does not need to see your demo ad today. They will, if you let LinkedIn or Google decide, because the platforms optimise for impressions filled, not for buyer experience.

We also rotate creative aggressively. Three to five variants per segment, refreshed every four to six weeks, keeps the audience from developing the “this ad again” reflex that signals creative fatigue.

Channel choice for retargeting

Most B2B tech accounts default to display retargeting via Google Ads. Cheap, easy to set up, gets the job done at the basic level. The trouble is that Google Display network inventory is mixed quality, and a percentage of impressions inevitably serves on placements that do nothing for a serious B2B brand.

Our usual stack on a mid-market B2B tech retargeting layer:

LinkedIn for high-intent and account-based retargeting (more expensive per impression but cleaner placements)
Google Display with curated placements (manual placement exclusions, audience signals, value-based bidding) for mid-intent
YouTube for video retargeting on the low-intent layer
Programmatic via DV360 or The Trade Desk for clients running at scale, with publisher allow-lists
Meta retargeting in selected categories where the audience justifies it
Reddit ads for B2B where the buyer audience genuinely lives there

The portion of the budget on each varies, but for most clients LinkedIn carries the high-intent retargeting (because the audience quality is best) and Google Display carries the mid- and low-intent layers (because cost per impression is much lower).

Creative that works in a retargeting context

Retargeting creative has a different job to acquisition creative. The audience already knows you. They have visited the site. They do not need an explainer. What they need is a reason to come back and a credible next step.

Patterns that consistently work:

Case study creative naming a recognisable client and a specific outcome. We work with clients like Littlefish, Codestone and Aspire Technology Solutions, and case-study creative featuring named clients consistently outperforms abstract value propositions.
Comparison content for buyers researching alternatives. A “vs [competitor]” ad to a buyer who has visited a competitor comparison page is high relevance. LinkedIn document ads carry this kind of comparison content well in the feed.
Peer-call or briefing invites for the high-intent segment. A direct, personal-sounding offer (“a 20-minute call with our head of [function]”) often outperforms a generic demo CTA.
Trust-led creative referencing certifications, named industries served and concrete outcomes. The placement of trust signals matters as much as their content, and we cover this in designing trust signals that convert IT directors.

What does not work consistently: generic “book a demo” CTAs to broad audiences, stock photography over a vague headline, recycled awareness creative repurposed without modification.

Suppression lists are non-negotiable

Three suppression lists belong on every B2B retargeting campaign:

Existing customers, matched from CRM. Do not pitch new business to people who have bought.
Recent converters, time-bounded. Anyone who has filled a form in the last 30 days does not need to see the same ad.
Sales-progressed accounts. Anyone whose company has reached a late opportunity stage should be in the brand layer, not the conversion layer, while sales is in conversation.

The CRM integration to push these lists into Google, LinkedIn and Microsoft is part of the conversion-tracking work we cover in conversion tracking for long B2B sales cycles.

Measuring retargeting honestly

Retargeting is the channel where last-click attribution does the most damage. Almost any return-path conversion will appear to come from retargeting under last-click, regardless of whether retargeting actually moved the buyer or simply intercepted a buyer who was returning anyway.

We typically measure retargeting against three honest tests:

View-through conversions with a sensible window (1 to 7 days, not 30)
Incrementality testing where the spend justifies it (geo holdouts or audience holdouts)
Multi-touch contribution within an attribution model that gives credit beyond last-click

The full attribution conversation lives in attribution models for tech companies with multi-touch journeys.

If your retargeting is producing strong-looking metrics on paper but the sales team is not seeing more pipeline, the chances are the channel is intercepting rather than influencing.
