What we speed up
Six reasons
your website is slow
The free audit shows which of them affect your website. We start with the ones that give the most speed for the least money.
Unnecessary scripts
Live chat, ad pixels, widgets and forgotten trackers load before the page itself. We remove what you don't need and load the rest after the page has opened.
WordPressAdsAnalyticsFonts
Five font weights from a third-party server hold up your text. We keep the ones you need and serve them from your own server, so the text appears straight away.
Any websiteGermanyGoogle's speed report
Google measures how your website loads for real visitors and shows the results in Search Console, in its page experience report. We work out why your pages are in the red or yellow zone and fix the causes. If Google has little data on your site yet, we go by the PageSpeed measurement.
Search ConsoleSEOMobile version
Google rates your website mainly by its mobile version, and PageSpeed tests it on a slow mobile connection. We speed up the mobile version and, along the way, fix buttons and links that are hard to tap.

While we speed up your website, we check what stops Google from finding it: page titles and descriptions, the sitemap, broken links and duplicate pages.

How we work
From audit to report
in four steps
Free
Audit and request
You check your website with our free audit or send us a link. We reply with what's slowing it down and a fixed price.
50% upfront
Access and backup
You add us as a member of your code repository and hosting, and we show you how. Before the first changes, we make a backup of the website.
Website stays live
Optimization
If your hosting allows it, we work on a test copy first and only then on the live website. Leads and orders keep coming in the whole time.
50% after the report
Report
We send you the before and after PageSpeed measurements and a list of what we did. For 30 days after handover, if anything we did doesn't work as it should, we fix it for free.
Guarantees
Price, timeline and ownership
are written into the contract
You see these terms in the contract before the first payment, and every message gets a reply within 24 hours.
Price and timeline in the contract
We name them before we start and write them into the contract as exact figures. “From” prices appear only on the website. As long as the task stays the same, so do the price and the timeline.
Payment in stages
Small project: half at the start and half at launch, once you've seen the finished work. Online store, CRM or web app: payment in stages, and we start the next one after you've accepted the previous one.
Everything in your name
The domain, hosting, repository and service accounts are in your name from day one. At handover you get a list of all accesses, so you never have to ask us for a password.
A working version every week
While we build, we send you a link to the working version once a week. You open it yourself, click around and send us your changes.
30 days of free fixes
Any bug we missed in the first 30 days after launch, we fix for free. After that, you can add maintenance from €19 a month with response times in the contract.

FAQ
Common questions
about website speed optimization
Website speed optimization from DLU costs from €190 for a landing page or small site and from €390 for a whole business site or store. Quick fixes take 3–5 working days, the whole site 1–2 weeks. The price includes a backup before changes and a report with before and after PageSpeed scores. Moving hosting and new features are quoted separately.
A website is usually slow because of heavy images, chat and ad scripts, extra fonts and slow hosting. Almost all of this can be fixed on your current site, without a rebuild. Start with the free audit: it shows your mobile speed score and the main causes. You can then fix them yourself or order speed optimization, where quick fixes take 3–5 working days.
Usually not: speed optimization fixes images, scripts, fonts and server settings on your current website. A rebuild is rarely needed, for example when pages are slow because of how the site itself works or because of outdated libraries. If the audit shows that speeding it up would cost more than a new website, we tell you and give you both prices, and the choice is yours.
A good PageSpeed score is 90 or above, 50–89 means the speed needs work, and we don't promise 100 before the audit. The score depends on hosting and on services your business needs, such as live chat, ads or online booking. After the audit, we tell you what's realistic for your site. We measure before and after under the same conditions, on mobile, and attach it to the report.
We speed up only websites built with JavaScript or TypeScript: React, Next.js, Vue, Nuxt, Angular, Svelte, Node.js. We don't take sites on builders (Wix, Tilda, Webflow, Shopify, Shoptet), WordPress or PHP, where a specialist in that platform will do better. If you don't know what your site runs on, run the free audit or send us the link and we'll tell you. Sites we built ourselves, we always take.
Yes, page speed is one of Google's ranking signals and part of the Google Ads landing page rating that affects your cost per click. For rankings, content matters more than speed, so a fast site won't reach the top on speed alone. A slow page loses visitors whose clicks you've already paid for, because on a phone people close it before it loads.
The free audit checks one page automatically and shows its scores and main problems, while speed optimization fixes those problems on your website. The audit runs online, needs no access to your site and sends a detailed PDF by email. In speed optimization we go through the homepage and key pages by hand, fix the causes and send a report with before and after PageSpeed scores.
