This competitive density changes the rules of the game: saturated channels lose efficiency, acquisition costs rise, and generic approaches are no longer sufficient to capture attention. For entrepreneurs looking to structure their marketing, the challenge is not finding tactics, but choosing those that align with their stage of development and actual resources.
First-party data and the end of third-party cookies: what changes for SMEs
Since 2024, Google has been gradually phasing out third-party cookies in Chrome. At the same time, the CNIL has increased its warnings regarding non-compliant trackers throughout 2024. These two simultaneous movements reduce the ability of small businesses to target audiences through traditional advertising networks.

The most direct response is to collect one’s own data. Some SMEs are strengthening their loyalty programs, member clubs, and premium content to build a base of first-party data usable in email automation. A sign-up form for a sector-specific newsletter, access to a free tool, or a referral program generates declarative data, which is inherently compliant with GDPR.
Among the marketing articles from Culture Entrepreneur, several discuss the concrete implementation of these collection mechanisms for budget-constrained companies.

Field feedback varies on this point: some SMEs see a rapid increase in their qualified base, while others struggle to reach a sufficient volume to fuel automated campaigns. The size of the existing audience and the purchase frequency of the product or service play a decisive role in the speed of building this base.
Creator-led strategies in B2B: beyond classic influence
B2B marketing influence is no longer limited to sponsoring a LinkedIn post. Since 2024, B2B SMEs have been structuring recurring collaborations with specialized creators: niche podcasters, authors of sector-specific newsletters, technical micro-influencers. LinkedIn’s “B2B Marketing Benchmark 2025” indicates that campaigns co-created with “B2B creators” generate sustainable engagement that exceeds brand-only campaigns.
The difference with classic influence lies in duration and integration. It is not a one-off placement but a video series, a recurring educational format, or a community jointly animated. These setups are part of the ongoing media plan, not a test budget.
What this implies in terms of resources
Collaborating with a specialized creator requires coordination time, not just a media budget. The brief must allow space for the creator’s own tone, or it risks producing promotional content that the audience immediately identifies.
For a starting entrepreneur, identifying one or two creators whose audience precisely overlaps with their target is better than spreading a budget across five high-audience but poorly qualified profiles. The selection criterion is not the number of followers but the response and conversation rate in the comments.
Content and social networks: arbitrate between channels rather than covering all
The temptation to publish on all social networks at once remains frequent. Available data do not allow for a conclusion that one channel consistently outperforms others across all sectors. However, one observation regularly recurs: companies that focus their efforts on two channels achieve better results than those that feed five channels irregularly.
The arbitration relies on three concrete criteria:
- The actual presence of the target on the channel (not the total size of the platform, but the density of your specific segment)
- The native format of the channel and its compatibility with your production capacity (short video, long text, static visual)
- The actual cost of producing quality content on this channel, in hours of work, not just in advertising budget
An entrepreneur who excels in writing will have more impact with a weekly newsletter and LinkedIn posts than with Instagram Reels produced reluctantly. Content marketing works when the chosen format is sustainable over time.
The question of video content
Video remains the format that captures the most attention on the majority of platforms. Campaigns incorporating short video (under 60 seconds) are among the most shared formats on social media. However, producing quality video requires an initial investment in equipment and editing skills that not all structures can absorb.
A gradual approach works better than a massive launch: start with simple formats (on-camera, narrated screen capture), measure engagement, and then invest in production if results justify it.
Marketing campaign analysis: measure before optimizing
Many entrepreneurs launch campaigns without first defining what they consider a success. Click-through rate, cost per acquisition, conversion rate on the landing page: each indicator tells a different story.
Before multiplying analysis tools, asking three questions is enough to frame the measurement:
- What is the direct business objective of this campaign (sale, appointment booking, registration)?
- What is the maximum amount I am willing to spend to acquire a customer through this channel?
- How often will I review the data to adjust the setup?
Free tools (Google Analytics, native dashboards of social platforms) cover most of an SME’s needs. The issue is not the sophistication of the tool but the regularity of the analysis. A dashboard reviewed weekly with five indicators is better than a monthly report of forty metrics that no one reads.
Digital marketing is evolving due to regulatory restrictions on data, the rise of specialized creators, and the saturation of traditional channels. For an entrepreneur, the strongest strategy in 2025 is not the broadest but one that aligns a mastered channel, self-collected data, and regular content.
Structures that apply this concentration logic before expanding their setup are the ones that stabilize their acquisition in the long term.
