Context
A high-potential market, but highly competitive
The online car rental market in France is structurally dominated by major international players with considerable marketing budgets: Sixt, Hertz, Avis and Europcar occupy the top positions, with brand recognition and legitimacy deeply embedded in the minds of French travellers.
Yet this market carries a paradox: renting a car remains a stressful experience for 33% of French holidaymakers (source: Markteffect study, October 2025). Hidden fees, surprises at the counter, aggressive upselling on insurance: car rental is experienced less as the start of an adventure and more as an exercise in risk management.
Sunny Cars: a virtually unknown brand at launch
Despite a strong and distinctive value proposition (the all-inclusive, no-surprises formula), Sunny Cars entered the French consumer market from a position of near-invisibility.
Faced with this dual challenge of generating bookings in the short term whilst building lasting brand awareness in a foreign market, Sunny Cars sought to partner with an agency combining sector-specific tourism expertise with hands-on knowledge of the French market.
Red Online Marketing became a strategic partner from July 2024, with a remit covering all digital acquisition channels:
- SEO: audit, content production, link building
- SEA: Google Ads and Microsoft Ads campaigns
- Meta Ads: full-funnel strategy (awareness, consideration, conversion)
- Affiliate Marketing: launch and management of the TradeTracker programme (started in 2025)
The approach was designed to address both identified challenges directly: building organic visibility and brand awareness over the long term, whilst running performance-driven paid campaigns to generate bookings from the outset. Red Online Marketing, with over 20 years of experience in tourism marketing and an office based in Lille, brought the dual dimension that was essential: sector knowledge and local grounding in the target market.
SEO work began in July 2024. The strategy was structured around three simultaneous pillars: domain authority (link building), content (destination pages and blog), and technical optimisation (site structure, Schema.org markup, mobile performance).
A comprehensive SEO audit was carried out, covering keyword opportunities, competitive analysis, content, technical aspects and domain authority. This served as the roadmap for all subsequent actions.
The blog was launched in Q3 2025, targeting informational top-of-funnel queries (“highway code”, destination guides, road trips) to broaden keyword coverage beyond transactional pages.
Alongside the editorial work, a link-building strategy was implemented from 2025 onwards, with the aim of progressively strengthening sunnycars.fr’s domain authority by acquiring inbound links from quality editorial sources within the travel and tourism space.
The Google Ads strategy is built on a full-funnel architecture: Search campaigns (brand and non-brand by destination), Performance Max, and Demand Gen (SEE, THINK, DO) to cover the entire customer journey. A target CPA is set with the client.
Microsoft Ads (Bing) is managed as a complementary channel, targeting a different audience profile: typically older, with higher purchase intent.

The Meta Ads strategy follows the SEE > THINK > DO framework:
- SEE: awareness phase, cold audiences
- THINK: consideration phase, qualified traffic, Advantage+
- DO: dynamic retargeting by destination, targeting website visitors
The DO phase was active from November 2024. The SEE and THINK phases were launched in June 2025. Video formats (UGC in particular) and destination visuals (islands, road trips) are the strongest-performing creative drivers.
Dedicated ad copy and visuals were developed for each target audience segment: families, couples without children, and seniors.

AI-generated videos were also produced and have consistently delivered strong performance results (watch an example on YouTube).
The affiliate programme was launched on the TradeTracker platform in late 2025. The strategy deliberately excludes cashback and promotional code sites, in favour of high-quality editorial partners: travel blogs, specialist comparison sites and content creators.
Since the launch of the partnership, key performance indicators have progressed across all channels. At a global level on the French market, 2025 marks a significant first milestone:
- +37% revenue generated vs 2024
- +45% bookings recorded vs 2024
- +49% sessions on sunnycars.fr vs 2024
Brand awareness, measured by the average search volume for “Sunny Cars” on Google France, clearly reflects the brand’s growth trajectory and the impact of our digital strategy.

SEO & link building
The starting position was characteristic of a brand with limited maturity in a foreign market: DR 34–36 (Ahrefs), limited keyword coverage, thin destination pages, and a domain authority significantly behind direct competitors. The link-building strategy, launched in 2025, has delivered consistent, measurable progress:

| Period | Domain Rating | Referring domains |
|---|---|---|
| Early 2025 | 34 | ~115 |
| Q1 2026 | 43 | 156 |
| Q2–Q3 2026 | 46 | 370+ |
+10 DR points and +255 referring domains in under two years. On organic rankings, Italy entered the top 10, a significant number of keywords moved into page 2 positions (11–20), and organic traffic recorded +49% growth in 2025 (GA4).
The rise in brand awareness is also visible on Google Trends: searches for “Sunny Cars” in France grew from an index of 3 in 2023 to an index of 20 in 2025, a sevenfold increase in two years.
SEA: Google Ads
The Google Ads trajectory over three years illustrates the combined effect of scaling investment and continuous campaign optimisation, with a near-stable CPA despite the progressive integration of awareness-oriented campaigns (Demand Gen, YouTube) that are naturally less focused on direct conversion:
| Period | Budget spent | Bookings | Average CPA |
|---|---|---|---|
| Nov 2022 – Oct 2023 | Baseline | Baseline | Baseline |
| Nov 2023 – Oct 2024 | +220% | +211% | -0.6% below target |
| Nov 2024 – Sept 2025 | +41% | +45% | -0.3% below target |
That represents +351% in budget and +352% in bookings since the start of the partnership. On Microsoft Ads (Bing), the channel is performing well ahead of its target CPA, with a conversion rate of 2.67% YTD 2026.
Affiliate marketing
Launched in late 2025 on TradeTracker, the affiliate programme generated a ROAS of 868% across the first seven months of 2026.
Growth has been consistent since May 2026. The programme is built on a deliberately selective, quality-first approach: cashback and promotional code sites have been excluded in favour of travel editorial partners. The next priority is to diversify the publisher portfolio.
