The 9 steps to build a fast, secure, and scalable website
April 17, 2025 — Simon Kelly
A well-built website is one of the most powerful resources in your marketing and sales toolkit–but only if it’s built properly from the ground up.
Whether you’re working with a web design agency or going the DIY route, there’s a lot to cover: website speed, SEO, security, scalability, and user experience all affect how your site performs and grows.
To help you stay on track, we’ve created this WordPress website checklist.
Follow these 9 essential steps to ensure your site is launch-ready, future-proof, and built to perform.
Before creating a website brief, it’s essential to map out your goals and strategy.
Every high-performing website starts with a clear strategy.
Taking time to define your objectives, understand your audience, and plan your website structure will ensure the build process is smoother and more effective.
It also sets your team and any external partners up with a shared understanding of the purpose behind every page and feature.
Here’s a website strategy and planning checklist:
Design isn’t just about looking good, it’s about making your website easy and intuitive.
Good design helps users find what they need, feel confident in your brand, and take action without friction.
It’s the difference between someone staying on your site and converting, or bouncing within seconds.
A thoughtful design also ensures your site works across devices and feels consistent throughout.
Here’s a checklist for design and UX:
Your content should be easy to read, aligned with your brand, and designed to convert.
Strong website content communicates value clearly and keeps users engaged.
It should reflect your brand’s tone of voice, answer your audience’s most important questions, and drive them toward the action you want them to take.
Structure matters too; how your content is laid out can dramatically impact how well it’s understood and retained.
Here’s our content and structure checklist:
Build your site with search and AI visibility in mind from day one.
Search Engine Optimisation (SEO) helps your site get found by the right people, without paying for every click.
Getting the technical and on-page basics right during the website build will give your site a much stronger foundation and help you avoid costly SEO fixes later.
It also ensures your content can be indexed and understood by search engines.
Here’s our checklist for SEO:
Website speed impacts both SEO and user experience. A fast site isn’t optional, it’s expected.
Speed is one of the most important technical factors in the performance of a website.
Your visitors expect sites to load quickly, and search engines reward performance with better rankings.
Optimising images, reducing unnecessary scripts, and using the right tools can make a huge difference to how quickly your site loads and how long users stick around.
Protect your site, data, and users with the proper precautions and ongoing website maintenance.
Website security isn’t just about avoiding hacks, it’s about protecting your brand’s reputation, your customer data, and your ability to stay online.
A few basic precautions can prevent major problems later, especially if your site handles enquiries, payments, or sensitive content.
Here’s our checklist for security and stability:
Build your website with growth in mind.
Your website should support your business today and in the future.
That means using tools, structures, and workflows that allow you to grow, whether it’s adding new services, running ad campaigns, or integrating a new CRM.
Scalability also means designing with simplicity, so your site can evolve without needing to start from scratch.
Here’s our scalability and flexibility checklist:
Make sure your site does what it needs to and can connect with your other tools.
Modern websites aren’t standalone—they’re central to marketing, sales, and fulfilment across the customer journey.
From contact forms to email systems, CRMs to analytics tools, your WordPress site should integrate smoothly with the platforms you already use. Functionality should also be tested thoroughly so that everything works as expected from day one.
Here’s our forms and integrations checklist:
Ready to go live? Tick off these last essentials.
Your website might be built, but it’s not ready to launch until it’s been fully tested and optimised.
This checklist ensures your site performs well, is user-friendly, and is ready to be seen by search engines, customers, and your broader audience.
Here’s the website pre-launch checklist:
