Retargeting vs Prospecting: Which Strategy Works Better?

Retargeting vs Prospecting: The Fundamental Difference

  • Prospecting — showing ads to new users who haven’t interacted with your brand
  • Retargeting — showing ads to users who’ve previously visited your site, clicked an ad, or engaged with your content

Both are essential. The best campaigns use both in concert — prospecting fills the top of the funnel, retargeting closes conversions at the bottom.

Comparison: Retargeting vs Prospecting

Factor Prospecting Retargeting
Audience size Very large Limited by site traffic
CPM Lower Higher (smaller pool)
CTR Lower 2–10x higher
Conversion rate Lower (cold traffic) Higher (warm audience)
Best stage Awareness, reach Conversion, retention
CPA Higher Lower

Popunder Ads for Prospecting

Popunder ads excel at prospecting — they reach massive audiences at low CPM, exposing new users to your brand or offer at scale. This makes popunder campaigns ideal for:

  • Building brand awareness in new GEOs
  • Driving initial traffic to offers for retargeting pixel collection
  • Testing new verticals and offers with minimal investment

Setting Up a Retargeting + Prospecting Funnel

  1. Step 1 — Prospecting: Run popunder campaigns on Adsailor to drive broad traffic to your landing page. Set up a retargeting pixel on landing page visits.
  2. Step 2 — Collect audience: After 5,000–10,000 unique visitors, your retargeting pool is large enough to work with.
  3. Step 3 — Retargeting: Use Google Ads, Facebook Ads, or native platforms to retarget non-converting visitors with a different message or offer.
  4. Step 4 — Optimize: Measure overall funnel CPA across both prospecting + retargeting spend combined.

Frequently Asked Questions

Is retargeting more effective than prospecting?

Retargeting delivers lower CPA, but you need prospecting to build your audience. Both are necessary — retargeting alone is limited by your existing traffic.

Can popunder ads be used for retargeting?

Most popunder networks don’t support pixel-based retargeting directly. Use popunders for prospecting and dedicated retargeting platforms (Google, Facebook) for follow-up.

What’s a good retargeting window?

30–90 days is standard. For high-consideration purchases, extend to 180 days. For impulse offers, a 7-day window is sufficient.
