The essentials
- Formula: CPC = spend ÷ clicks. On Meta, distinguish between “clicks (all)”, which include reactions and profile openings, and “outbound link clicks”, the only ones comparable to the traffic measured in GA4.
- 2026 French ranges: Meta €0.40 to €1.20 (outbound click), TikTok €0.20 to €0.60, LinkedIn €5 to €12, YouTube €0.30 to €0.80.
- CPC derives from CPM and CTR: CPC = CPM ÷ (CTR × 10). A high CPC comes either from expensive access or from a creative that does not make people click.
- Steering: CPC is the metric for traffic campaigns; for lead or sales campaigns, it only serves as a diagnostic.
Cost per click is the most read and the most misread metric in social ads. Misread, because platforms do not count the same thing behind the word “click”, and because a low CPC guarantees nothing about what happens after the click. Here is what CPC really measures on Meta, LinkedIn and TikTok, the ranges observed in France in 2026, the mechanics that link it to CPM and CTR, and the situations where it deserves to be the steering metric.
What each platform calls a click
| Platform | Metric | What is counted | Use |
|---|---|---|---|
| Meta | Clicks (all) | Link clicks, but also reactions, comments, shares, profile openings, image expansions | To ignore when measuring traffic |
| Meta | Link clicks | Clicks to the destination, including native forms and in-app product pages | Intermediate metric |
| Meta | Outbound clicks | Clicks that leave Facebook or Instagram for your site | The only metric comparable to GA4 sessions |
| Clicks | Depends on the objective: link clicks for “traffic”, any interaction for “engagement” | Check the objective before comparing | |
| TikTok | Clicks (destination) | Clicks to the landing page or the app | Comparable to Meta's outbound click |
The gap between “clicks (all)” and “outbound clicks” on Meta commonly reaches a factor of two to four. A report showing a CPC of €0.30 based on clicks (all) hides a cost per outbound click of €0.90. Always ask which metric was used. The residual gap between outbound clicks and GA4 sessions (20 to 40% loss) comes from consent, blockers and drop-offs before loading; the subject is covered in GA4 and SMA.
2026 ranges in France
| Platform and objective | Typical CPC | Typical CTR | Note |
|---|---|---|---|
| Meta, traffic objective | €0.25 to €0.60 | 1.2 to 2.5% | Attracts compulsive clickers, high bounce rate |
| Meta, conversions objective (outbound click) | €0.60 to €1.50 | 0.8 to 1.5% | More expensive clicks, but 2 to 3 times more conversions |
| Meta, retargeting | €0.50 to €1.20 | 1.5 to 3% | High CPM offset by a strong CTR |
| TikTok, conversions objective | €0.20 to €0.60 | 0.8 to 1.5% | The cheapest, but a younger audience |
| LinkedIn, sponsored content | €5 to €12 | 0.4 to 0.7% | Up to €20 on executive targets |
| LinkedIn, native form | €4 to €9 | 0.5 to 0.9% | The click opens the pre-filled form |
| YouTube, in-stream | €0.30 to €0.80 | 0.3 to 0.6% | Clicks are rare, cost per view is more relevant |
Highly competitive sectors (insurance, credit, property, training) sit at the top of the ranges, or beyond. The CPM ranges underlying these CPCs are detailed in understanding CPM.
The mechanics: CPM, CTR and CPC
Social ads are bought on impressions. CPC is only a consequence: CPC = CPM ÷ (CTR × 10). With a CPM of €8 and a CTR of 1%, the CPC is €0.80; if the CTR rises to 2%, the CPC falls to €0.40 without the access price having changed. This formula says where to look when CPC goes off course:
- Stable CPM, falling CTR: the creative is wearing out (frequency too high) or does not match the audience. This is the most frequent case.
- Rising CPM, stable CTR: seasonal competition or too narrow an audience; CPC rises without the ad being at fault.
- Both are deteriorating: the campaign has exhausted its audience; creatives must be renewed and the targeting widened.
On Meta, CTR also influences CPM: the auction factors in an estimate of expected quality and engagement. An ad that makes people click therefore pays less for its impressions, which doubles the effect of a good creative. Testing methods are described in A/B testing in advertising.
When to steer on CPC, and when to ignore it
- Traffic campaigns (content launch, event, site awareness): outbound CPC is the main metric, complemented by bounce rate and session duration in GA4.
- Lead or sales campaigns: CPC is a diagnostic metric. A campaign with a CPC of €1.20 and a conversion rate of 5% (cost per conversion €24) is worth more than a campaign at €0.40 converting at 1% (€40). Steer on cost per conversion, described in the definition of CPA.
- CPC bidding: LinkedIn offers manual CPC bidding, useful for capping cost on a narrow target. Meta and TikTok optimise on impressions towards the chosen objective; CPC bidding is not a common lever there.
The levers for reducing CPC without damaging what follows
- The creative: the first lever. A hook in the first three seconds of video, a visual that contrasts with the feed, a text that announces what people will find after the click.
- Objective consistency: a “conversions” campaign shows a higher CPC but traffic that converts; do not switch to “traffic” to bring the CPC down.
- The placements: Reels, Stories and Audience Network offer lower CPCs; check that the conversion rate follows, placement by placement, as explained in automatic or manual placements.
- The frequency: beyond 3 to 4 exposures on prospecting, CTR drops off; renew or widen.
- The exclusions: removing existing customers and recent converters from prospecting campaigns avoids paying for clicks with no value.

Frequently asked questions
What is a good CPC on Facebook and Instagram in 2026?
Between €0.40 and €1.20 per outbound click for a conversion campaign in France, across all sectors. Below €0.30, check that the metric is not “clicks (all)”. Above €1.50, look at the CTR: if it is under 0.8%, the creative is at fault before the audience.
Why does my LinkedIn CPC exceed €10?
Because precise professional targeting (job, company, sector) reaches a reduced inventory contested by high-margin B2B advertisers. A CPC of €8 to €12 is normal; it exceeds €15 to €20 on executives and large companies. The useful question is the cost per qualified lead, not the CPC.
Is TikTok's CPC really lower than Meta's?
Yes, by 40 to 60% on average in 2026, thanks to abundant video inventory and still lower advertising competition. The trade-off: a younger audience, a need for native creatives renewed every week, and an often lower conversion rate, which brings cost per purchase closer to Meta's.
Should you bid on CPC or CPM?
On Meta and TikTok, leave the automatic bid optimised towards your objective; CPC bidding does not exist as a main strategy. On LinkedIn, manual CPC bidding lets you cap the cost on a small target, at the price of reduced volume; test it against automatic bidding over two weeks before adopting it.
