What The Industry Research Report Covers

The 70+ pages of research benchmarks each retailer based on 50+ metrics and indicators of successful digital strategy, including organic visibility, domain authority, paid media ads, conversion performance, technical performance, site speed, universal search, content, social ads, accessibility, and mobile performance.  

Driving Optimal ROAS from Paid Media Channels

Some of the leading players in the space are high spenders on paid media channels such as Google, Bing & Facebook - but have a poor or sub-optimal conversion improvement strategy. Without an optimised, sophisticated conversion strategy that maximises the conversion rate, the return on investment is unsustainable or will underperform. Scaling spend on paid media is not achievable unless the conversion rate delivers optimal performance in the sector. Some in the space have paid media spend levels from 30k+ per month but dedicate minimal resources and budgets to conversion testing.  Given the cost per clicks on ad networks will continue to rise, we recommend spending at least 10% of your paid media budget on ongoing conversion optimisation testing schedules to ensure your paid media ROI maintains long-term viability, competitive advantage, and sustainability.

Pay-Per-Click Marketing

Pay-Per-Click marketing is constantly evolving, with more and more advertisers being forced to hand over a lot of control to Google's algorithms as the push for automation grows ever stronger. There are still key elements of control that we have though, the main one of these being budget which is ultimately something the algorithms can't take from you. That's why being smart with your budget and ad coverage is essential to achieving strong results and bettering what your competitors have to offer.

For Q4 2025, the average monthly budget wastage across these UK car rental companies was £19,752, with some of the top players in the market spending a considerable amount on areas and audiences unlikely to deliver a return. We can see this in more detail when looking at the average monthly cost per cost-per-click (CPC) amongst advertisers, with the average of this metric being £9 . This highlights how competitive the market is and how important it is to control your budgets effectively.

There are varying monthly ad budgets across the competitors in the report. While this gap highlights the competitive advantage that larger budgets can provide, it's not just about spending more; it’s about spending smarter. By focusing on driving efficiency in campaign management, targeting, and budget allocation, businesses with smaller budgets can still effectively compete with larger players. Investing in data-driven strategies and refining ad performance can help close the gap and maximise the return on every pound spent, enabling growth even in a competitive landscape. Relative to their spend, Indigo Car and Van Hire reported the lowest monthly cost-per-click (CPC) at £0, and Zipcar has the highest at £20.

The report highlights the importance of budget efficiency by comparing monthly ad spend with estimated CPC in relation to your competitors, see who has the highest and lowest CPC. To maximise the effectiveness of your budget, it’s essential to focus on driving CPC down while maintaining or improving campaign performance. In this report, Practical Car & Van Rental has the lowest estimate monthly ad spend at £2,660, and Enterprise Holdings has the highest at £406,000.

By optimising targeting, refining ad copy, and leveraging data to identify high-converting opportunities, you can ensure every click delivers maximum value. This approach not only stretches your budget further but also boosts your return on ad spend (ROAS), enabling you to achieve stronger results without simply increasing expenditure.

Technical Website Compliance

Savvy digital marketers know that having a technically sound website is an essential component of a successful fully integrated digital strategy - plus a site capable of maximising conversion performance. Car rental companies will want to take particular care that key pages such as locations and models are easy for users to find.

In our previous audit, Rentalcars.com received the most 404 errors (394). This quarter, Rentalcars.com remains the company to watch, and they’ve since increased their 404 errors to a total of 517, suggesting they’re not following a strategy to decrease these errors. If a page has been removed entirely or moved to a new URL without a 301 redirect, users and search engines trying to access the old location will hit a 404 error. This problem is especially common during large-scale content clean-ups, rebrands, or migrations. Proper redirect mapping prevents this and preserves both user experience and SEO value.

Site Speed & Conversion Rate Performance

When 62% of consumers are less likely to convert if they have a negative mobile site experience, ensuring that your site is quick and easy to load makes a significant improvement on your overall conversion rates. Just as with ensuring key pages are easy to navigate to, to avoid any prospective customer frustration, car rental companies will want to convey a fast site experience to ensure potential renters have a positive experience with their brand at every digital step.

In our last audit, Hertz received the slowest mobile site speed (18). This quarter, Hertz has increased their mobile site speed to 25. Seeing an increase in mobile site speed suggests they’re following a strategy to optimise their website for mobile users. Mobile site speed matters because users expect instant access to information when browsing on their phones. Slow-loading pages interrupt this expectation and make the experience feel frustrating. When users can’t quickly reach what they’re looking for, they’re far more likely to leave.

Building Competitive Advantage with Domain Authority

Domain authority is an essential metric for measuring the effectiveness of SEO performance, and helps create a reliable overall gauge of how effective your site is at achieving organic traffic, i.e. ‘free’ traffic that is not gained through sponsored ads. Car rental companies can look to collaborate with high-authority travel and lifestyle bloggers to build their backlink profiles, along with generating travel and motoring content that can be picked up by both national and sector-specific press.

A ‘good’ DA really comes down to how your competitors are performing, however it is generally considered average between 40 and 50, good between 50 and 60, and excellent above 60. In our last report, Indigo Car and Van Hire received the lowest DA score (23). This quarter, Indigo Car and Van Hire remains the company with the lowest DA, but they’ve since slightly increased their score to 24. Increasing domain authority requires patience and sustained effort. It’s not something that changes overnight, but a metric that improves as your site becomes stronger overall. By focusing on backlinks, technical improvements, and high-quality content, websites can steadily increase their score and build long-term organic visibility.

Organic Performance – Mobile & Desktop

A strong organic performance is strategically important as it ensures your site ranks above competitors for key, transactional keywords. When 93% of your customers won’t go past the first page of Google, your absence or lack of targeting for essential keywords will cost you conversions. Due to the cost-of-living crisis and consumers cutting back on expendables such as holidays, car rental companies may find that they are competing for a much smaller pool of traffic than in previous years.

Four brands reported a drop in organic traffic on desktop, with Thrifty Car and Van Rental receiving the biggest loss (-27%). On mobile, 3 brands saw a drop in organic traffic, with Thrifty Car and Van Rental receiving the biggest loss on this device, too (-90%). Brands can increase organic traffic by regularly updating their existing content. Older content can lose visibility over time, but refreshing it with new information, improved structure, and better optimisation can quickly restore rankings. This ongoing attention helps maintain traffic stability across devices.

Universal Search Opportunity

Google Universal Search Results is an evolving opportunity to make your pages visible on a SERP (Search Engine Results Page). Universal results often appear before traditional listings and are eye-catching for users. Universal search results refer to rankings on a SERP that are not the traditional ‘blue line’ Google link, and a retailer can appear for universal search results without being strong in standard rankings. 'Reviews' are a useful feature for car rental companies to capitalise on, helping them gain the trust of potential customers.

Enterprise Holdings continues to secure the most Universal Search appearances (17,169) — an increase from 12,733 previously. The majority of their appearances came from ‘images’ (6,700).

The Longtail Keyword Opportunity

Longtail keywords are often considered high intent and potentially more likely to convert as a searcher is being more specific. Optimising for longtail keywords also puts your content strategy in a strong position to rank for retailer new search terms as they enter Google’s index. Car rental companies must ensure their organic content strategy acknowledges high-conversion potential keywords, including terms such as 'available now', 'instant access', or 'cost for 7 days' (or any other common length of time).

Enterprise Holdings continues to secure the most longtail keyword appearances for position 3 (13,623) — an increase from 13,306 previously. Enterprise Holdings also continues to secure the most appearances for positions 4–10 (13,214) — a decrease from 13,426 previously. Longtail keywords fit perfectly within structured content such as FAQ blocks, schema markup, and conversational content. Since many longtail searches are question-based or voice-search driven, presenting answers in a clear and structured way can boost online visibility.

Facebook Adverts

With the number of Facebook users in the United Kingdom (UK) hitting over 44 million users in 2023, it is not surprising that companies have jumped at the opportunity to advertise on the social media platform. Facebook’s UK digital advertising revenue has been estimated to have breached 2.6b GB pounds in 2019. For car rental companies, Facebook ads are an opportunity to ensure customers are seeing offers, availability, and company options.

We’ve included screenshots of Practical Car & Van Rental’s sponsored Facebook posts. This UK car rental company should diversify the text on their posts to make each post unique to encourage more engagement.

Top Social Shares & Content

When it comes to social media and on-site content strategies, it is important to release content that has a longer shelf life. An article is considered 'Evergreen' if it has maintained its relevancy to an audience for longer. It's great for your retailer engagement, but great for Google too, who will recognise content which achieves traffic over a long period of time. As with building a backlink profile and creating content that ties in well with PR activity, car rental companies can look to developing topics within the holiday and automotive space to secure shareable content that will gain traction on social media.

SIXT secured the most Facebook Likes (1.2m) and the most Instagram followers (222,500). Facebook was the most popular social media platforms of all brands. SIXT received the highest total engagement rate (762) and the highest average engagement (54).

Website Readability & Accessibility

20% of people in the UK have a disability – 2 million of which are people living with sight loss. In addition, 1 in 12 men and 1 in 200 women have some degree of colour vision deficiency. When websites are not designed to meet these needs, retailers lose customer interest as they turn elsewhere. It is important for brands in any sector to be accessible for all potential visitors, even when this need is not immediately obvious, such as in the automotive sector.

In our previous report, Practical Car & Van Rental flagged the most accessibility alerts (70). This quarter, Practical Car & Van Rental reported 69 accessibility alerts. Although they’ve only see a reduction of one point, any progress is a step in the right direction for improve the user experience. By actively managing alerts, brands reduce neglecting some users.
