Site-Speed & Web Performance Consultant
Web performance affects every business. Find out how it affects yours.
I work with organisations of all sizes to analyse, find, and fix site-speed issues. Together, we answer questions such as:
- How much does a one-second slowdown affect conversion rates?
- Are third-party scripts affecting engagement?
- How does site-speed influence revenue?
It’s my job to help you find the answers.
Every consultancy engagement is tailored to the client and project. Your engagement will combine some or all of the following:
- Analysis: You can’t fix what you can’t measure. We’ll establish how site-speed affects your business and what web performance means for you. With that evidence, we can make meaningful improvements.
- Audits: I’m a technical consultant at heart, with forensic knowledge of networks and web browsers. My audits are famed for being extensive and detailed while remaining highly actionable. They uncover everything working against us.
- Implementation: Performance sprints are a highly effective way to realise returns fast. I’ll work alongside your engineering team to ship customer-facing site-speed improvements that earn you money. I won’t just find the problems — I’ll fix them.
- Culture: You should never need to call pest control twice. I’ll leave your team able to tackle these issues without me. Together, we’ll build a performance culture that considers site-speed from the start of every project. We’ll make it easy to do the right thing.
I pride myself on working with organisations, not merely for them. I care about this so much that I wrote a book about it.
Get Focused Answers in 90 Minutes
For lighter-touch guidance and advice, schedule a 90-minute consultation. We can answer your most pressing questions, including:
- What is a slow website costing your business?
- Where should you focus your efforts first?
- How can you troubleshoot a specific performance issue?
A consultation is a great choice if:
- You have a specific, distinct issue that you don’t need a weeks-long consultancy project to solve;
- You want to start your site-speed journey more tentatively, testing the water with a smaller commitment at the beginning.
If we go on to work together after the consultation, I’ll deduct its cost from your first consultancy invoice. Win-win, no risk!
A consultation is not just a call. After you schedule it, I’ll ask for any relevant research, homework, and tasks so I can prepare fully. Want me to look over some waterfall charts? You got it! Need me to debug some stuff? Send me a URL. Need a second opinion on your Vitals? I’m on it!
Questions About Consultancy?
How much will our web performance project cost?
Most audit and consultancy engagements are five-figure projects. For contained problems or smaller commitments, consultations and masterclasses offer more focused alternatives.
Do you work with smaller organisations?
Absolutely! While my client list tends to highlight more familiar household names, I love partnering with anyone who’s keen to do good work. In fact, some of my most fond memories are joining smaller teams and working closely together to solve problems.
Whether it’s consultancy, audits, or training, the size of your company does not matter. There’s something for everyone.
How long will our web performance project take?
Probably not as long as you think! Over the past decade, I have managed to optimise my workflow to such an extent that we can move incredibly quickly. Vitamix had this to say about it:
Harry’s technique for getting to the root of our needs was phenomenal—he proposed a tailor made plan of action, and it was spot on. We were able to implement it immediately and it didn’t take weeks or months of ramp-up time. It was as if Harry had been in the trenches with us all along!
No matter how long it will take us to achieve our goals, the sooner we start, the better.
