Website performance audit

Every visitor you win - from ads, from search, from referrals - lands on the same website. If it's slow, you're paying full price for traffic and converting a fraction of it. This audit shows what that's costing you.

Sound familiar?

  • The site feels fine on your laptop, but conversion rates on mobile tell a different story.
  • You're paying for clicks that bounce before the page has even finished loading.
  • Google keeps flagging "poor page experience" - and it stays unfixed.
  • Every new marketing tool added "just one small script" - and the site got a little heavier each time.
  • Your developers say performance is fine; your customers' phones disagree.

What the audit tells you

Real-world speed

How fast your site actually is for real visitors on real phones - measured the way Google measures it, not the way it feels at your desk.

The commercial cost

What slowness costs across three fronts at once: abandoned visitors, higher ad costs on penalised landing pages, and lost search rankings.

The culprits, named

Exactly which images, scripts and marketing tools are responsible for the weight - with the evidence to settle who fixes what.

Marketing's own weight

How much of the slowdown is marketing's doing - tags, trackers and consent tools taxing every page view.

What Google sees

Whether search engines can actually read your content - or whether parts of your site are invisible to the thing that ranks it.

Quick wins first

The fixes split into config-level changes that need no engineering project, and the genuine builds - so improvement starts this month, not next quarter.

23 MB

One page weighed 23 megabytes - mostly images the visitor never sees - and the cookie tool, declaring ~960 ad vendors, added a full second of processing to every page.

Frequently asked questions

What is a website performance audit?

A review of how fast and stable your website actually is for real visitors - not how it feels on your office laptop. It measures what Google measures, identifies exactly which assets and tools are slowing you down, and separates the fixes that need an engineering project from the quick wins hiding in configuration.

Does site speed really affect revenue?

Three ways. Visitors abandon slow pages before they convert - especially on mobile, where most first visits now happen. Google uses speed as a ranking signal, so a slow site earns less free traffic. Ad platforms penalise slow landing pages with higher costs per click - so you pay more for every visitor a slow page then wastes.

Our site feels fast to us. Why would it be slow for customers?

Because you're on a fast machine, a fast connection, with the site cached from a hundred previous visits. Your buyers are on phones. In one recent audit a page weighed 23 megabytes - mostly images the visitor never sees - and the cookie tool alone added a full second of processing to every page.

Will this just tell our developers things they already know?

Developers usually know the site could be faster; what they lack is leadership cover to prioritise it, and evidence of what matters most. The audit provides both - every finding costed in commercial terms and ordered by impact, with the config-level quick wins separated from the genuine engineering work.
