TL;DR: Prospecting and retargeting are two essential phases of every Meta Ads strategy. Prospecting acquires new prospects; retargeting converts warm contacts. New brands should invest 70–80% of budget in prospecting; established businesses can allocate up to 50% to retargeting.
What is the difference between retargeting and prospecting in Meta Ads — and how much budget should go to each? Getting the retargeting vs. prospecting balance right is one of the biggest drivers of campaign ROI.
Quick Answer: Prospecting targets new, unknown audiences to generate awareness. Retargeting reaches people who have already interacted with your website or content. Both phases need dedicated budget — running only one of them leaves ROI on the table.
The Two Phases of the Meta Funnel
Every successful Meta Ads strategy thinks in two phases:
Prospecting (cold acquisition): You reach people who don't yet know your business. The goal is to generate attention and spark interest.
Retargeting (warm reactivation): You reach people who have already been in contact with you – website visitors, video viewers, previous customers. The goal is to drive action.
Those who only prospect lose the warm contacts. Those who only remarket run out of new interested parties. Both phases need dedicated budget.
Prospecting: Finding New Customers
Prospecting is the most expensive phase – but also the only one that enables sustainable growth.
Goal: Awareness + first conversion (lead, purchase, app download)
Suitable audiences:
- Lookalike Audiences based on your best customers
- Broad Targeting / Advantage+ Audience
- Interest targeting as a supplementary signal
Suitable creatives:
- Attention-grabbing Reels or videos (15–30 seconds)
- Explanatory content conveying the core message
- Problem-solution format: "Have this problem? We solve it."
KPIs:
- Cost per lead / cost per purchase
- ROAS (Return on Ad Spend)
- Click-through rate
Retargeting: Winning Back Warm Leads
Retargeting is the most efficient phase – because you're reaching people who have already shown interest.
Goal: Convert warm contacts
Suitable audiences:
- Website visitors (30–60 days)
- Users who visited pages but didn't convert (e.g., pricing page)
- Video viewers (75–95% of video)
- Instagram/Facebook engagers
- Email subscribers (Custom Audience)
Suitable creatives:
- Social proof (reviews, customer testimonials)
- Direct offers or reminders
- FAQ-based: address common objections
- Testimonial videos
KPIs:
- Cost per conversion (should be significantly lower than prospecting)
- Conversion rate
The Right Budget Split
There's no universal answer, but some benchmarks for Austrian SMBs:
New or little-known brand:
- 70–80% Prospecting | 20–30% Retargeting
- Reason: Little warm audience, needs to be built first
Established business with traffic:
- 50–60% Prospecting | 40–50% Retargeting
- Reason: Large warm audience that can be reactivated with manageable budget
Seasonal campaigns (e.g., Christmas, Black Friday):
- 40% Prospecting | 60% Retargeting
- Reason: Maximum ROI in short time through warm contacts
The Retargeting Burnout Problem
When your retargeting audience is too small or is targeted too long, the following happens:
- The same people see your ad daily
- Ad fatigue sets in: frequency rises, click-through rate falls, costs rise
- Users start actively hiding your ads (negative signal)
Solution: Set frequency caps (e.g., max. 3 impressions per person per week) and continuously replenish the retargeting audience with fresh traffic from prospecting campaigns.
How to Measure Success in Both Phases
Measure prospecting and retargeting separately – and compare them complementarily, not directly:
- Prospecting: affordable cost per reach, good CTR, acceptable CPA (higher than retargeting)
- Retargeting: lower reach, but significantly lower CPA
A very low retargeting CPA can be misleading: if you run minimal prospecting, retargeting might simply be reaching people who would have converted anyway – even without an ad.
Frequently Asked Questions
Why does retargeting convert better than prospecting? Because the audience has already interacted with your brand and shown initial interest. This pre-qualification reduces the persuasion work needed and therefore the cost per conversion substantially.
Can I run both phases on a small budget? With a very small budget (under €300 per month), we recommend focusing exclusively on retargeting first — provided you already have enough organic traffic. This delivers the fastest ROI. Prospecting requires more budget to generate meaningful data.
How often should I refresh my prospecting audiences? Lookalike Audiences and interest targeting should be reviewed every 4–8 weeks and renewed when performance declines. Advantage+ Audience adjusts automatically and requires less manual intervention.
What happens if I stop prospecting entirely? Costs drop in the short term. Over time, your warm audience shrinks and retargeting becomes more expensive and less effective. Without ongoing prospecting, your funnel has no new inflows.
The balance between prospecting and retargeting is not a static setting but a dynamic decision that changes with your business growth and audience size. If you're unsure whether your current budget split is optimally structured, we'd be happy to analyze it for you. Get in touch with webflix.at.
