Is retargeting cheaper than prospecting?

Per conversion, yes, retargeting almost always shows a lower CPA and higher ROAS in the reporting interface. But that number is misleading. Retargeting only talks to people prospecting already warmed up, so it inherits the easy conversions. The true cost of acquiring a customer includes the prospecting spend that created the demand in the first place. Look at blended CPA across both, not retargeting in isolation.

What budget split should I use between prospecting and retargeting?

For most growing accounts, start around 70 to 80 percent prospecting and 20 to 30 percent retargeting. Retargeting audiences are small, so they cannot absorb much budget without frequency getting annoying and returns collapsing. Heavy retargeting accounts usually have a hidden problem: they are recycling demand instead of creating it. Adjust based on how much warm traffic you actually have to work with.

Can I run only retargeting to save money?

You can, but only as a short-term efficiency play, and it will stall. A retargeting-only account harvests demand created elsewhere, by your SEO, your prospecting in the past, or someone else's marketing. As that warm pool empties, performance drops and there is nothing refilling it. Without prospecting, your retargeting pool shrinks every week. To grow rather than maintain, you must spend on cold reach.

Why does my retargeting ROAS look so good but revenue is not growing?

Classic symptom of an over-weighted retargeting setup. The ROAS looks great because last-click credits retargeting for conversions that would likely have happened anyway. Meanwhile you are starving the prospecting that brings new people in, so the total audience is not expanding. Run a holdout test, pause retargeting for a slice of users and measure the real incremental lift. It is usually lower than the dashboard suggests.

Which platform is better for each, Meta or Google?

It depends on intent. Google Search is unbeatable for prospecting where buyers already search for a solution, capturing high intent at the moment of need. Meta is strong for both demand creation prospecting (cold interest and lookalike audiences) and visual retargeting (dynamic product ads for cart abandoners). Most accounts use Google for intent capture and Meta for demand creation plus retargeting, rather than choosing one platform for everything.

How do I measure retargeting properly without fooling myself?

Stop judging it on last-click CPA alone. Use incrementality: run periodic holdout or geo tests where a portion of warm users see no retargeting, then compare conversion rates. The gap is the real value retargeting adds. Pair that with clean GA4 and server-side tracking so attribution is not double-counting. Without this, you will keep over-investing in a channel that mostly takes credit for prospecting's work.

Retargeting vs Prospecting: Where Your Next Euro Should Go

Book a Call Get a Free Audit

Retargeting and prospecting are not competing channels. They are two jobs inside the same funnel. Prospecting finds people who have never heard of you and creates new demand. Retargeting follows up with people who already showed interest and pushes them to convert. If you only do one, your account either stalls or quietly cannibalises demand you already had.

The short answer most advertisers need: retargeting almost always shows a lower CPA and a higher ROAS in the reporting interface, but that number is flattering and partly fake. Those users were already close to buying. Prospecting carries a higher visible CPA because it pays for the hard part, getting a stranger to care. Judging both on the same last-click number is the single most common reason accounts plateau.

This page breaks down what each actually does, the cost ranges you can realistically expect in Euro, and how to split the budget by business model. Whether you run e-commerce, B2B lead gen, or a service business, the goal is the same: spend enough on prospecting to keep the pipeline full, and enough on retargeting to close it, without paying twice for the same customer.

Head-to-Head Comparison

Feature	Retargeting	Prospecting
Core job	Convert warm audiences who already visited, engaged, or added to cart	Create new demand and reach cold audiences who never heard of you
Cost model	Mostly CPM-based on Meta, occasionally CPC. You pay to re-reach a known list	CPC on Google Search, CPM on social and display. You pay to find people
Typical CPCs / CPMs	Meta retargeting CPMs often 8 to 25 Euro, but small high-intent audiences	Search CPCs roughly 1 to 6 Euro, prospecting CPMs on social 4 to 15 Euro (experience ranges)
Targeting basis	Your own data: site visitors, video viewers, cart abandoners, customer lists	Intent (search terms) or interest and lookalike signals for cold reach
Buyer intent	High. These users already raised their hand at least once	Mixed. Search prospecting is high intent, social prospecting is low to medium
Funnel stage	Mid and bottom: consideration to decision	Top and mid: awareness and first consideration
Creative load	Lower. Reminders, offers, social proof, urgency. Reuse and rotate	Higher. Must explain who you are and why it matters from a cold start
Time to results	Fast, days, but capped by how much warm traffic exists	Slower, weeks, but this is what raises your ceiling over time
B2B vs B2C fit	Works for both, essential for long B2B sales cycles and abandoned carts	Works for both, the only way to grow beyond your current audience size
Measurability	Looks great on last-click, easy to over-credit, watch incrementality	Looks worse on last-click but drives the conversions retargeting then claims
Realistic minimum budget	Small, 200 to 500 Euro per month can work if traffic exists to retarget	Larger, plan 1,000 Euro+ per month to gather enough learning data
Scaling ceiling	Hard cap: limited by audience size, you cannot scale past your traffic	High: the engine that lets the whole account grow

Retargeting Strengths

Highest visible conversion rate and lowest cost per action in the platform, because you only spend on people who already showed interest
Recovers revenue that would otherwise leak: abandoned carts, half-finished forms, and browsers who left without buying
Cheap to run relative to impact, since audiences are small and creative can be reused and rotated
Essential for long B2B cycles where buyers compare for weeks and need repeated reminders before they act
Fast feedback and easy to switch on, a quick win for accounts that already have meaningful traffic

Prospecting Strengths

The only lever that grows your total audience: without prospecting your retargeting pool slowly dries up
Captures high-intent demand on Google Search at the exact moment someone is looking for what you sell
Builds the brand recognition that makes every later retargeting touch cheaper and more effective
Sets the real ceiling on revenue, more qualified strangers in means more conversions out across the funnel
Generates the first-party data and pixel events that retargeting depends on to function at all

When to Use Retargeting

Lean into retargeting when you already have steady traffic but conversions are leaking, classic e-commerce cart abandonment, or B2B prospects who downloaded a guide and went quiet. It is also the right first move when budget is tight and you need an efficient win to prove the channel before asking for more spend. Just never let retargeting be your only line, because a retargeting-only account is just slowly harvesting demand someone else created and will stall the moment your warm pool empties.

When to Use Prospecting

Prioritise prospecting when growth has flattened, when your retargeting audiences are shrinking, or when you are entering a new market where almost nobody knows you yet. Any business trying to actually grow rather than just maintain needs the majority of working budget here. Search prospecting suits high-intent lead gen and e-commerce with clear demand, while social prospecting suits visual products and categories where you must create demand before anyone searches for it.

Our Verdict

Run both, but weight by maturity and goal. For most growing accounts a 70 to 80 percent prospecting and 20 to 30 percent retargeting split is the honest starting point. Retargeting feels efficient precisely because prospecting did the expensive work first. If you flip the ratio and pour budget into retargeting because the dashboard ROAS looks better, you optimise yourself into a corner: spend rises, audiences shrink, and growth quietly dies.

The sequencing logic matters more than the exact percentage. Build the demand engine first with prospecting (Google Search for intent capture, Meta or other social for demand creation), then layer retargeting on top to close what prospecting opened. Judge prospecting on new customer acquisition and blended CPA across the whole account, not on its standalone last-click numbers. Judge retargeting on incremental lift, not on the conversions it would have got anyway. Run a periodic holdout or pause test on retargeting to see how much it truly adds.

By business model: e-commerce should run both continuously, prospecting on social and Shopping, retargeting for cart and product viewers. B2B lead gen leans on Search prospecting plus patient long-window retargeting for slow buying committees, see our take in google-ads-vs-meta-ads. Tight budgets under 1,000 Euro per month should start with whichever channel has clear intent (usually Search) plus light retargeting, then expand prospecting as data comes in. If you want a second opinion on where your spend leaks, our audit will show exactly how your prospecting and retargeting are really performing once you strip out the double-counting.
