Frequently Asked Questions
This really depends on the size of the project and what you need. If it’s on the smaller side you’d be looking at 6-10 weeks and if it’s on the larger side 12-18 weeks. However, these are very rough estimates and your best bet is to get in touch with us so we can understand your needs and be able to give you an accurate time estimate.
Our agency has been building websites for over 24 years and over that time have built a wide range of digital solutions. Our exceptional team includes highly experienced designers, front-end developers, back-end developers and digital marketers with a proven track record of creating results for our clients.
Absolutely! It is standard practice for clients to continue working with us after their website launch. By keeping a monthly retainer, our web developers can maintain and improve your website’s performance.
We always start with a discovery session where we immerse ourselves in your brand, gaining a deep understanding of its unique identity to ensure that your voice and messaging are seamlessly reflected on your website. More importantly, we get a clear understanding of your objectives and what success looks like to you, then we put together a strategy and plan in place to deliver on these objectives.
Following this, we’ll enter the design phase where we start with a low fidelity wireframe version of your site. This helps us to establish user journeys and content hierarchy without any brand-led distractions. Once we have a solid foundation, we move onto the design phase. Here, we’ll render the site in full detail, working with you to ensure your brand is used correctly, applying it to best in class UX.
Once you love the design, our development team builds the site in sprints, and our QA team will run test sprints to test each element of the site to make sure it’s all perfect. Any application / 3rd party inclusions will feel seamlessly part of the brand journey as we will style their front end interfaces to be totally fitting with your style guide.
To ensure your new website ranks well in search results, focus on technical SEO by optimising page speed, mobile-friendliness, and secure HTTPS. Implement on-page SEO with keyword-rich meta tags, headers, and structured content. Create high-quality, valuable content that engages users and earns backlinks.
Ensure proper indexing by submitting a sitemap and fixing broken links. If targeting local or international audiences, optimise with Google Business Profile and hreflang tags. Finally, track performance with Google Analytics & Search Console, staying updated with SEO trends for continuous improvement.
Absolutely, you’ll have access to our expert analytics team that will ensure you can track every interaction on your site and keep an eye on the performance. This involves setting up and configuring robust analytics platforms, such as Google Analytics, to track key metrics like user behaviour, traffic sources, and conversion rates. Our analytics team will create personalised dashboards and reports, allowing you to easily visualise and interpret the data, ensuring you have a clear picture of how your site is performing.
