The French e-commerce sector generates tens of billions of euros each year, and the creation of micro-enterprises related to digital continues to rise. However, launching an online business remains an exercise where the majority of projects fail in the first months, often for measurable reasons: poor choice of acquisition channel, payment friction, or excessive reliance on paid advertising. What indicators distinguish the strategies that work from those that stagnate?
Customer acquisition cost by channel: what the data shows
The choice of acquisition channel determines the profitability of an online business well before the quality of the product or service. The cost differences between channels are significant, and recent regulatory changes (GDPR, restrictions on third-party cookies) have reshuffled the deck.

| Acquisition Channel | Relative Cost per Customer | Time to Results | Cookie Restriction Sensitivity |
|---|---|---|---|
| SEO (organic content) | Low to medium | 6 to 12 months | Very low |
| Paid advertising (Meta, Google Ads) | High and rising | Immediate | High |
| Email marketing (first-party data) | Very low | Medium (list building) | None |
| Organic social media | Low | 3 to 6 months | Low |
| Partnerships and affiliate marketing | Variable (commission) | 1 to 3 months | Low |
Paid advertising offers quick results, but its cost per acquisition increases year after year. Updates from the CNIL and European regulators on cookie consent have reduced the effectiveness of retargeting and lookalike audiences. Shopify and other platforms have been emphasizing since 2024-2025 the importance of a first-party data strategy to compensate for the declining effectiveness of third-party cookies.
Several resources detail these trade-offs between channels, notably the site businesshack.fr in detail which maps out different approaches to structuring an online business.

First-party data and email: the asset most entrepreneurs overlook
Direct collection of emails, creation of customer accounts, and loyalty programs constitute what is called first-party data. Unlike data from targeted advertising, this information belongs to the business owner and does not depend on any third-party algorithm.
An entrepreneur launching an online store or web service has every interest in building their email list from day one. Email marketing has the lowest cost per conversion of all digital channels. The trade-off: it takes several months to build a sufficient base.
Building a usable email list
- Offer free content in exchange for signing up (PDF guide, mini-course, checklist), directly related to the product or service sold
- Segment subscribers upon registration based on their main interest, to send relevant sequences rather than generic newsletters
- Automate post-purchase follow-ups and welcome sequences, which generate significantly higher open rates than mass sends
This approach requires an investment of time, not advertising budget. For a content creator or seller of digital products, the email list becomes the main commercial asset, one that survives changes in social media algorithms.
Payment process and conversion rates: the underestimated friction point
Attracting visitors to a site is pointless if the payment process drives buyers away. The European DSP2 directive has generalized strong customer authentication (SCA), imposing additional steps during checkout (3D Secure 2, biometrics, one-time codes).
A poorly optimized payment process can result in a significant loss of sales at the very moment the customer is ready to buy. Stripe emphasizes the fine management of SCA to limit friction and payment declines.
Reducing payment-related cart abandonment
The problem is not limited to the choice of a payment provider. The entire checkout user experience must be rethought.
- Reduce the number of fields to fill out to the strict minimum (name, email, card)
- Clearly display shipping fees before the payment step to avoid last-minute surprises
- Offer multiple payment methods (card, bank transfer, digital wallets) tailored to local customer habits
- Regularly test the process on mobile, where the majority of abandonments occur
Businesses selling physical products via a web store or on marketplaces like Amazon are particularly exposed to this issue. Each additional step in the purchase funnel represents a measurable loss.
Developing an online business: investing in content or advertising
Content creation (articles, videos, podcasts) and paid advertising respond to opposing logics. Organic content builds a sustainable asset: a well-ranked article continues to attract visitors for years. Paid advertising stops as soon as the budget is cut.
On the other hand, organic content produces no results during the first months, which puts entrepreneurs who need quick cash flow in difficulty. The most effective combination is to use paid advertising to validate an offer and generate immediate revenue, while simultaneously building a foundation of SEO content and an email list.
Content creators transitioning to selling digital products (courses, templates, tools) illustrate this dynamic well. Their organic audience, built over several months, becomes the main sales channel, making paid advertising optional.
The choice between these two approaches depends on a simple parameter: the available cash flow at launch. An entrepreneur with a few months of financial reserves should prioritize content and email. Those who need to generate revenue immediately will turn to advertising, knowing that the cost of customer acquisition through this channel will continue to rise year after year, due to the combined effects of competition and regulatory restrictions on advertising tracking.
The data that summarizes the current state of the market can be stated in one sentence: the cheapest channels to exploit are also the slowest to produce results. All the trade-offs of launching an online business hinge on this tension between speed and cost.
