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 Q2 2025, the average monthly budget wastage across these UK diamond dealers was £10,617, 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 £28 . 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, Sacet reported the lowest monthly cost-per-click (CPC) at £0, and Boodles has the highest at £149.

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, London Diamonds has the lowest estimate monthly ad spend at £127, and Diamonds Factory has the highest at £230,000.

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. When customers are looking to invest in high-value items, such as diamonds, an exceptional site experience is essential for not losing trust in your brand before they can reach the item they want.

In our previous audit, Fenton reported 168 4xx errors. This quarter, Fenton remains the diamond dealer to watch, and they’ve increased these errors to 176. 404 errors can increase bounce rates, as visitors are more likely to grow frustrated with a website that directs them to broken pages. 

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 minimising technical errors, diamond dealers will want to ensure their site is quick and easy to use, in order to maximise buying-potential in their luxury items.

The mobile site speed for this quarter ranged between 41 and 4, with Purely Diamonds flagging the slowest mobile site speed. This UK diamond dealer should ensure they’re utilising lazy loading and that their website is mobile-friendly to help increase their mobile site speed.

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. For diamond dealers, working with a digital PR strategist will enable them to target niche opportunities to build links, in a way that fits their luxury image.

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. The DA this quarter ranged between 63 and 22, with Sacet reporting the lowest DA score. This diamond dealer should ensure they’re taking every opportunity to increase the quantity and quality of their backlinks. Posting original, in-depth content is one of the most effective ways to achieve this.

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. Across all sectors, we are seeing brands selling luxury, or treat, items fall in traffic year on year so, diamond dealers are likely to be competing for a smaller pool of organic visitors.

Three UK diamond dealers brands reported a decrease of organic traffic on desktop, with London Diamonds (-11%). On mobile, 5 UK diamond dealers reported a decrease of organic traffic, with Sacet seeing the biggest decline (-78%). All diamond dealers should ensure they’re following a keyword strategy to help increase their organic traffic on all 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 brand can appear for universal search results without being strong in standard rankings. 'Image pack' results would be a useful universal search result for diamond dealers wanting to show their products directly on the SERP, while results such as 'FAQs' and 'people also ask' content can assist and build trust with buyers looking to make a one-off purchase.

Diamonds Factory continued to secure the most Universal Search appearances overall (10,239) — a decrease from 18,101 in our previous audit. On the other hand, Sacet received the fewest overall appearances (36). This UK diamond dealer should look for missed opportunity to increase this figure in the future, which could have a positive impact on their online ranking in search engines.

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. Diamond dealers appearing for FAQ and people also ask universal search results may find their performance is strong for longtail keywords, putting them in good stead for one-off or first time diamond customers looking for helpful information before making their purchase.

Diamonds Factory secured the most longtail keyword appearances for position 3 (3,205) and positions 4–10 (2,929). Though further down the list for position 3, The Diamond Store came second place for appearances for positions 4–10 (2,041) — which is an effective way to increase a website’s overall ranking in search engines.

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 The Diamond Store’s sponsored Facebook posts. This UK diamond dealer included bullet posts for each post, which is a great way for brands to make their content more scannable.

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. Diamond dealers can create engaging content on the history of diamonds, common settings and shapes, and education pieces around technical terms used by retailers.

The Diamond Store has the most Facebook Likes (217,400) and London Diamonds reported the most Instagram followers (212,600). All UK diamond dealers should ensure they’re using unique branding with imagery to help make their content easily recognisable to social media users.

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. Diamond dealers will want to ensure their sites look sleek, clean, and elegant. However, diamond dealers must ensure that form is not taking priority over function, and that any aesthetic choices do not come at the cost of accessibilty.

 In our previous report, Diamonds Factory flagged 353 accessibility alerts. This quarter, Diamonds Factory has dramatically decreased these alerts to 2, and they reported the fewest accessibility alerts of all diamond dealers. Currently, the one to watch is London Diamonds, with 471 accessibility alerts. This UK diamond dealer should check for empty links/buttons, keyboard navigation issues, and more.
