VsRelax: same budget, better results.
The Google Ads campaign was already working well. We rebuilt the website’s technical foundation and conversion tracking while leaving the advertising unchanged. A one-month comparison showed 82% more conversions on the same ad budget.

Previously 4.9 sThe campaign worked. The foundation needed work.
We had worked with VsRelax for over a year. The WordPress site was up in its original implementation, the Google Ads campaign was built and optimized for a small budget, and bookings came in steadily. On the campaign side, things were in order.
The technical foundation was the bottleneck. LCP was 4.9 seconds, and conversion tracking relied solely on the browser pixel. iOS restrictions and browser privacy changes were leaving a share of results unmeasured. Continuously optimizing the WordPress foundation would have cost the small business more than it would return, so the question was: is there another option that solves both problems without an unreasonable price?
Same design. Faster website.
LCP: the time it takes for the largest visible content element to load, before and after the rebuild.
Same appearance. New technology.
We improved website speed and tracking. The campaign, keywords, ad copy and ad budget stayed the same.
Visually identical, technically new
We rebuilt the site as a hand-coded foundation, visually pixel-identical to the old WordPress version. Users notice no change except that the page loads faster.
LCP from 4.9 to 2.1 seconds
The time for the largest visible content element to render (LCP) decreased by 2.8 seconds, or approximately 57%, after the rebuild. Recent mobile CrUX data shows an LCP of 1 s over the last 28 days (PageSpeed Insights, checked on 29 September 2026).
Conversion tracking moved server-side
We replaced traditional browser-side tracking with server-side tracking, so iOS restrictions and browser privacy changes no longer leave a share of bookings unmeasured.
Advertising was not touched
The campaign, ad groups, keywords, bidding strategy and ad copy were all left as they were. We wanted to see how much the technical foundation alone changes the result.
Same ad budget. More conversions.
Conversions in a one-month comparison
111 → 203 conversions
In a one-month comparison, the change spoke for itself. The ad budget stayed the same. Clicks and impressions stayed essentially flat. But the number of conversions rose from 111 to 203, an 82 percent lift. Cost per click fell from €2.95 to €1.88, a 36 percent reduction.
This example proves that the technical foundation is one of the largest multipliers in advertising. It is not an add-on, nor a nice-to-have. Same campaign, same budget, different technical foundation, and the result is +82% conversions.
The lift wasn't a one-month outlier. Enquiry levels have stayed above +80% from December 2025 onwards — a five-month follow-up confirms the change was lasting.
