What The Industry Research Report Covers

The 70+ pages of research benchmarks each site 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 Q3 2025, the average monthly budget wastage across these UK energy providers was £81,869, 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 £76 . 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, E.ON reported the lowest monthly cost-per-click (CPC) at £11, and Shell Energy has the highest at £645.

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, Utilita Energy has the lowest estimate monthly ad spend at £456, and British Gas has the highest at £1,330,000.

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. Energy providers will want to ensure key information, such as rates and quote generators, are clearly signposted and not blocked off by broken links.

In our previous audit, SSE Renewables flagged the most 404 errors (409). This quarter, SSE Renewables has completely eliminated all 404 errors, and they’re the only energy provider to have zero 404 errors. Currently, OVO Energy received the most 404 errors (275). Websites can prevent internal broken links by regularly auditing their site with crawling tools to identify and fix outdated or incorrect URLs. Implementing proper redirects when pages are moved or deleted helps maintain link integrity. Additionally, using a consistent URL structure and updating links during content changes reduces the risk of 404 errors in the first place.

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. As with technical site compliance, energy providers will want to ensure their site is optimised for mobile, by ensuring their website theme is suitable to use on a smaller screen.

In our previous report, both ScottishPower and Green Energy UK flagged the slowest mobile site speed (26). This quarter, ScottishPower has reduced their mobile site speed to 25, making them the energy provider to watch. However, Green Energy UK has slightly increased their mobile site speed to 28. An ideal mobile site speed is under 3 seconds, as users tend to leave if a page takes longer to load. Faster speeds improve user experience, engagement, and conversion rates. Search engines like Google also prioritise quicker-loading sites in mobile rankings.

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 isn’t gained through sponsored ads. Energy providers would benefit from engaging with a digital PR specialist, who can identify opportunities to reclaim backlinks, and create engaging content that national press will want to share.

A ‘good’ DA really comes down to how your competitors are performing, however, it’s generally considered average between 40 and 50, good between 50 and 60, and excellent above 60. In our last report, Green Energy UK reported the lowest DA (52). This quarter, Green Energy UK has slightly increased their DA score to 53, no longer putting them at the bottom of the leaderboard. Shell Energy is currently the energy provider with the lowest DA (49). A website’s domain authority is mainly affected by the quality and quantity of its backlinks from reputable, relevant sites. Other factors include the site’s overall content quality, internal linking structure, and technical SEO health. Consistent updates and strong user engagement can also contribute to higher authority over time.

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. Fluctuating energy prices will have consumers shopping around to try and identify the best price. Therefore, energy providers must have a strong organic strategy to capitalise on this restless consumer base.

10/12 energy providers saw a decrease in organic traffic on desktop, and 9 saw a decrease on mobile. Previously, Shell Energy saw the biggest traffic drop on both devices (-66% on desktop, and -69% on mobile). This quarter, Shell Energy saw a -55% loss on desktop, and npower Business Solutions reported the biggest loss on mobile (-39%). There’s often a difference between desktop and mobile organic traffic because user behaviour and intent vary across devices. Desktop users may conduct in-depth research, while mobile users often seek quick answers or local results. Mobile traffic can also be influenced by site speed and mobile-friendliness. Additionally, smaller screens and different browsing contexts can affect how users interact with search results.

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 site can appear for universal search results without being strong in standard rankings. Optimising for 'people also ask' results is a great way to build brand awareness and confidence directly from the SERP, as energy providers can provide much-needed answers before users have set virtual foot on their site

British Gas remains at the top of the leaderboard for the most Universal Search appearances (17,843), a decrease from 30,786 in our previous report. The majority of these appearances came from ‘people also ask’ (16,700).

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 brand new search terms as they enter Google’s index. Energy suppliers should look for opportunities to use longtail keywords throughout their website, as these phrases have a low-competitive, high-conversion rate.

British Gas secured the most longtail keyword appearances for position 3 (11,329) and the most appearances for positions 4–10 (17,133). Longtail keywords are effective for gaining traffic because they target specific search intent, attracting users who are more likely to convert. They face less competition than broad keywords, making it easier to rank higher in search results. Additionally, they help websites reach niche audiences and drive highly relevant, engaged visitors.

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.

We’ve included screenshots of EDF’s sponsored Facebook posts. This UK energy provider included vertical videos to optimise their content to social media users on a mobile.

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 brand engagement, but great for Google too, who will recognise content which achieves traffic over a long period of time. Content such as energy-saving tips and advice will be engaging, topical, and most likely to be shared by social media users.

Octopus Energy secured the most Facebook Likes (234,000) and the most Instagram followers (115,300). Facebook was the most popular social media platforms of all brands. Octopus Energy received the highest total engagement rate (143,335), and OVO Energy secured the highest average engagement (507).

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, brands lose customer interest as they turn elsewhere. As energy is an essential need for any customer, energy providers must ensure their sites are universally accessible.

In our last report, EDF reported the most accessibility alerts (253). This quarter, EDF has increased their accessibility alerts to 255, continuing to make them the energy provider to watch. Websites should treat accessibility alerts as signals that parts of their site may be difficult for users with disabilities to navigate. Addressing issues like poor colour contrast, missing alt text, or improper heading structures ensures inclusivity and compliance with standards. Fixing these alerts not only improves user experience but can also benefit SEO and brand reputation.
