Pagespeed audits
improve Core Web Vitals

Let's stop you from focussing on the wrong metrics, start prioritizing real e-commerce optimizations instead.

Pick your audit


Pagespeed audit in a nutshell

Unlike an in-house pagespeed training, a pagespeed audit is specific to your webshop, no matter the platform your webshop is running on.

Nowadays better known as Core Web Vitals. I will cover perceived performance to technical UX, including third party contents. For example:

  • Previous work

    Share with me your pagespeed optimizations so far. I will explain why it might not have led to results yet, despite Lighthouse saying so.

  • Already tried it all?

    Are developers telling you that the webshop's pagespeed can't improve further due to hosting, platform, framework, GTM or your design?

  • Core Web Vitals

    I will audit on Core Web Vitals and beyond. For example, is current image CDN + webp strategy positively impacting your webshop's performance?

  • Missing out on revenue

    It looks fast on your device, but is UX for everyone? That is where Core Web Vitals comes in. I'll put focus on the right metrics.

Pagespeed audit usage

You will receive a PDF file with historic data as well as recommendations with code-examples where appropriate.

  • Start to address UX bottlenecks that is really holding back conversion;
  • As a product owner, you can use this as technical proof of current imperfections;
  • As a dev-team, you can use it to extend and prioritize your in-house roadmap;
  • Indication of costs and benefits per recommendation is included.

Frequently asked questions

Getting started

  • There will be no doubt that I will find bottlenecks. Even a, coolblue and wehkamp are leaving money on the table. However, I would like to hear from you or your stakeholders where your bottlenecks are. If your team already started addressing pagespeed, send me an export of your backlog or roadmap as well.

  • It depends on the platform, your team's knowledge of the platform as well as performance best practices. For example, excluding project management/communication overhead, within a clean Laravel shop, it could take one to two weeks.

    When having a Magento 1, Lightspeed or Shopware 6 shop, this could become up to 3 weeks week. When using Shopify or Magento including its coding conventions, this could become 2 to 3 weeks. We all now that there is more overhead involved in e-commerce projects, but its hard to already make statements about that.

  • There are different factors in play. For example, do you have a seasonal webshop, does weather play a role? But also, what platform are you using and what is the sitespeed/performance knowledge of your team. To reduce lead time, let me train your developers as well.

    When it comes to Core Web Vitals, it could take up to 28 days if optimizations correctly and depending on current scores.


  • Historic data, frontend performance, covering TTFB, DNS lookups, cookies, redundant code, render blocking resources, resource hints, font loading strategy, (client side) caching strategy, image loading, used libraries, main thread blocking, code deduplication, third party widgets, loading on demand and maybe anti-patterns due to other optimizations. Obviously, Core Web Vitals -introduced in May 2020- is part of the audit as well.

  • Partially. Making the right choice when it comes to server side performance (hosting + platform) is up to you. At the same time, when -for example- TTFB's are quite high, for example for API responses, it sometimes is possible to determine if their is a caching or SQL-query bottleneck.

    However, most collaborations isn't covering a deep dive into server side performance. At the same time, while having build the fastest CMS out there, you can invite me to putting our heads together.

  • My work is only focussing on web performance and the work that is done between the code of your site or shop and the browser. Native Apple iOS or Android apps not running in a browser, isn't part of my expertise.

  • Yes I can. That's even part of the 3-page template type audit. You can also schedule a single consult afterwards, when you've booked the 1-page template audit.

e.g. beat competition, improve ranking, improve Lighthouse score to x%, increase conversion by y%

I generally respond within 8 to 16 office hours. You'll be sent a copy of the e-mail as well.
