Work with our web performance specialists
Let’s be real: first impressions matter. Your website will be most people’s first impression of your business. From site speed and layout to user experience, a visually pleasing and user-friendly website is crucial to your online performance. Google’s recent updates all point to the importance of page experience as a ranking factor. But, just as importantly, your website is your virtual greeting – and you want to be sure you’re welcoming potential customers with a firm, friendly handshake.
Here at Passion we help you put your data in order so you can get the performance insights your business needs. We base our recommendations on a firm foundation of analysis, including behaviour research and customer journey mapping, so that your website doesn’t just look appealing – it is made to perform. Tracking and testing is a vital part of any of our web builds so that we can make sure that our optimisations lead to conversions.

Do you also design and build websites?
We do! We love building beautiful websites that exceed our clients’ expectations in terms of UX, conversion rate and speed performance. However, we are not a web agency – we are a performance marketing agency, so our team is best placed to design and build focussed, highly-optimised, small websites instead of big enterprise sites.
If you choose us to design and develop your site, we’ll help you every step of the way:
- Prototyping and UI – including wireframing and high fidelity
- Development – HTML5, CSS3, JavaScript React and Vue, PHP Stack and more
- JAMstack design and dev
- WordPress design and dev
- Crafting and sanity checking
- Contentful, Sanity, Netlify and Gatsby Cloud
What is your preferred web build platform?
We believe that websites need to be fast and secure while still meeting the needs of an ever-changing online landscape, as well as your business goals. To achieve this, we use GatsbyGS, a static site generator, to pull content directly from your CMS or other data sources, giving you quick-loading, optimised websites with the most up-to-date online security.
This decoupling of the CMS and website means your content managers can enjoy the familiarity and user friendliness of WordPress or Craft, while your developers and designers are free to implement bespoke designs and user journeys with almost no limitations. This approach ensures your website can evolve seamlessly with your business.
