When we first saw Discover Cars advertising a 365-day cookie and 70% profit share, we were sceptical. Those numbers sound too good. Eighteen months later, here's the honest review.

What Discover Cars Actually Pays

Discover Cars pays 70% of their profit per booking — not 70% of the booking total. Their profit margin is typically 15–25% of the booking value, so your actual commission works out to roughly 10–17% of what the customer pays. On a $400 AUD car rental in Bali, expect $40–68 commission. That's significantly better than Rentalcars.com (40% of their commission) or Booking.com's car rental (variable, typically 4–6%).

Yes, meaningfully. Travel research often starts 6–12 months before booking, especially for major trips. We've seen commissions attributed from clicks made 8 months prior. For "best time to visit Bali" content published in November, you'll still earn on bookings made the following October when those readers actually travel.

What Traffic Converts Best

Bali converts exceptionally well — Australians hire cars in Bali at very high rates. The USA (especially California highway trips), New Zealand self-drive and European road trips also convert strongly. Budget destination content (where car hire is a significant portion of total cost) converts better than luxury destinations.

Dashboard and Tracking

The Discover Cars affiliate dashboard is functional but not beautiful. Real-time tracking, good reporting by link/campaign, and a dedicated affiliate manager who actually responds within 24 hours. We've found tracking reliability to be excellent — better than some larger networks.

Our Verdict

Discover Cars is our highest-earning affiliate program per click, ahead of Booking.com and Viator. The combination of a generous commission structure and an industry-leading cookie window makes it the standout car rental program for Australian publishers. Sign up and prioritise building car rental content — it compounds over time.

Discover Cars is a car rental comparison aggregator that has carved a specific niche in the affiliate market through an extraordinary cookie duration: 365 days (compared to the standard 30-day window from Rentalcars.com and AutoEurope). This means a reader who clicks your Discover Cars affiliate link today and books a car rental 11 months later still generates commission for your blog. For content about travel planning -- where the research phase and the booking phase can be months apart -- a 365-day cookie captures revenue that a 30-day cookie would miss entirely.

Discover Cars Affiliate Economics

Commission rate: 70% of Discover Cars' profit margin on referred bookings, which translates to approximately 4-7% of the total rental value depending on the rental profile. Average booking value: EUR 350-600 (AUD $570-980) per completed rental. Per-booking commission: approximately AUD $23-68 depending on booking value and margin. The 365-day cookie combined with these commission rates creates one of the better-performing car rental affiliate programmes for Australian travel blogs that produce evergreen content -- posts about European road trips, Icelandic rental cars, and USA self-drive itineraries continue generating commissions for a full year after each reader's first click.

Discover Cars' inventory covers 145+ countries with competitive pricing at major European, US, and Australian airport locations. The platform's search results include the full excess inclusion information upfront, making it easier for readers to understand the total cost of each option -- this transparency reduces comparison confusion and potentially improves conversion. The affiliate programme is managed directly through Discover Cars' partner portal (discovercars.com/affiliate-program) and provides standard deep linking and widget tools for embedding into destination content.

Discover Cars vs Rentalcars.com for Australian Travel Blogs

For Australian travel bloggers choosing between Discover Cars and Rentalcars.com as their primary car rental affiliate, the practical comparison comes down to cookie duration versus brand recognition. Discover Cars' 365-day cookie captures the significant 'research now, book much later' behaviour that is particularly common in long-haul travel planning (Australian travellers often research European car hire 6-9 months before departure). Rentalcars.com's 30-day cookie misses the majority of these delayed bookings. The counter-argument: Rentalcars.com is a Booking.com sister brand with higher Australian brand recognition, potentially producing higher conversion rates from brand-familiar readers. The practical recommendation for Australian travel blogs: run both affiliates on car hire content pages and compare 90-day performance data to determine which produces better revenue per page visitor for your specific audience.

Discover Cars' 365-day cookie is the most significant differentiator from any other car rental affiliate programme available to Australian travel bloggers. For content about long-haul travel planning -- where the research and booking decision can be separated by 6-9 months -- the yearlong attribution window captures revenue that industry-standard 30-day cookies systematically miss. Discover Cars' 365-day cookie is the most significant structural advantage available in the car rental affiliate space. For Australian travel blogs producing evergreen content about European road trips and international self-drive itineraries, the yearlong attribution window captures the delayed purchase behaviour that makes long-haul travel planning inherently different from short-booking-window categories. Discover Cars' 365-day cookie makes it the most appropriate car rental affiliate programme for Australian travel blogs producing evergreen international road trip content. The extended attribution window captures the delayed purchase decisions that characterise long-haul travel planning and transforms car hire content from a low-revenue afterthought into a meaningful contributor to overall affiliate income. The Discover Cars affiliate programme is worth implementing on any Australian travel blog that produces European or long-haul international road trip content. The combination of the 365-day cookie, the 4-7% commission rate, and the high average booking values from Australian travellers planning overseas self-drive itineraries creates a genuinely strong revenue per page visitor ratio for car hire content. Implement Discover Cars on every car hire content page and compare 90-day performance against Rentalcars.com. A 365-day cookie window transforms car hire from a low-attribution category into one where evergreen content continues generating commissions from readers who plan months in advance. Implement on all car hire content. The 365-day window is the product's most commercially important feature for evergreen travel content.

Discover Cars Affiliate Performance for Australian Travel Blogs

Discover Cars' affiliate programme performance benchmarks for Australian travel blogs: the platform converts well for car hire comparison content targeting Australian readers planning European, American, or New Zealand road trips. The 365-day cookie window is the programme's most distinctive feature -- a reader who clicks a Discover Cars affiliate link in January and books a rental in October still generates the affiliate commission. For Australian travel blogs with evergreen car hire content that receives consistent traffic throughout the year, this extended attribution window produces commissions from bookings that shorter-window programmes (the standard 30-day cookie) would miss. The content approach that drives Discover Cars conversions: posts framed as '[destination] car hire comparison' or 'how to avoid [destination] car hire scams' that integrate Discover Cars' comparison widget directly in the content produce the highest click-through rates. The widget (available through the affiliate dashboard) shows live pricing comparison across multiple rental companies for the reader's specific dates -- a genuinely useful tool that increases dwell time and conversion rate compared to static text links.
