Why retargeting is the most efficient spend in adviser media

Retargeting CPCs are typically 40-70% lower than prospecting CPCs, and conversion rates are 2-4x higher. For most UK adviser firms, retargeting is the single most efficient line item in the media budget. Yet it is usually the least optimised.

The retargeting audience stack

Tier 1: high-intent

  • Users who started a form but did not complete (180-day window).
  • Users who visited a specific product page (landing, pricing, adviser bio).
  • Users who engaged with a video ad 75%+ through.

Value: highest. CPL: lowest. Creative: problem-solving, urgency-building.

Tier 2: engaged

  • Visited the site 2+ times in 90 days.
  • Downloaded a lead magnet or used a calculator.
  • Clicked an ad but did not visit a specific product page.

Value: medium. CPL: moderate. Creative: trust-building, social-proof-heavy.

Tier 3: aware

  • Any site visit in the last 180 days.
  • Video viewers 25-75%.
  • Social engagers (likes, saves, shares).

Value: low. CPL: higher. Creative: awareness-building, top-of-funnel.

Frequency capping

Retargeting burnout kills the efficiency gain. Typical caps:

  • Tier 1: 4-6 impressions per week.
  • Tier 2: 3-4 impressions per week.
  • Tier 3: 2-3 impressions per week.

Exceed these and you see rising CPM (audience fatigue), falling CTR, and brand damage.

Creative rotation

Use a minimum of three creative concepts per audience tier. Rotate weekly. Pause any creative below median CPL after 14 days.

High-intent creative themes

  • "Still considering your pension options?"
  • "We saved your quote. Ready to book?"
  • "Here is what happens in a pension review."

Engaged creative themes

  • "Top 3 questions our clients ask about remortgage."
  • "Why 90% of our reviews are 5 star on Trustpilot."
  • "Meet your adviser: [named adviser bio video]."

Aware creative themes

  • Brand story.
  • Client testimonial.
  • Educational content.

View-through attribution

Meta and Google both attribute view-through conversions (a user saw the ad without clicking, then converted within 24 hours). In financial services:

  • Click-through attribution is usually stronger signal.
  • View-through should be weighted 20-30% of click-through.
  • Exclude view-through from ROAS calculation for bidding (use click-through only).

Exclusion lists: critical

Retargeting should exclude:

  • Existing clients (avoid service-spend on acquisition).
  • Users who already converted in the last 90 days.
  • Users who explicitly unsubscribed or opted out.
  • Job applicants and staff.

Upload these lists to all three platforms (Meta, Google, LinkedIn) and refresh monthly.

Compliance on retargeting

Retargeting creative is still a financial promotion. COBS 4 and Section 21 apply:

  • Risk warnings on every ad.
  • Approved-by date on file.
  • Vulnerable customer considerations (e.g. avoid urgency language on older equity release segments).

Platform specifics

Meta

  • Custom Audiences from pixel + engagement + CRM list.
  • Exclusion audiences easy to stack.
  • CAPI strongly recommended (first-party data matching).

Google

  • Remarketing Lists for Search Ads (RLSA) to bid higher on warm searchers.
  • Display retargeting cheap but low-conversion.
  • YouTube retargeting to engaged video viewers.

LinkedIn

  • Website retargeting (pixel-based).
  • Company-page visitor retargeting.
  • Content retargeting (lead-form openers, video viewers).
  • More expensive than Meta but higher-quality for B2B.

The retargeting budget rule

A healthy adviser media mix: 25-35% of total spend on retargeting, 65-75% on prospecting. If retargeting is more than 40%, you do not have enough top-of-funnel volume. If it is under 20%, you are wasting the efficiency gain.

Measuring retargeting ROI

Track:

  • Retargeting CPL vs prospecting CPL (should be 40-70% lower).
  • Retargeting MQL rate (should be 1.5-2x prospecting).
  • Retargeting attribution (7-day click, 1-day view is standard).

What next

Audit your current audience segmentation. If you have fewer than 5 retargeting audiences, start by building Tier 1 / Tier 2 / Tier 3 segments with proper exclusion lists. Then add creative rotation. Efficiency gains of 30-50% on the retargeting line item are typical.
