Don't let a slow landing page waste your advertising budget any longer!
Our experts optimize the page that receives your paid traffic, so that every euro invested yields more
We master your technical environment
A service in 3 key steps
A flat fee with no surprises: an exchange, an intervention, a deliverable.
Technical Alignment
01We discuss via video conference with you, and with your consultant or SEA agency if you have one. We review the landing page, the campaigns driving traffic to it, the targeted conversion (lead, purchase, appointment booking), your technical stack, and the marketing tools in place: Tag Manager, pixels, consent, CRM. This ensures a targeted intervention on what is actually costing you conversions.
Intervention
02We analyze the page as a visitor from an ad sees it: consistency between the ad and the page (message match), first screen, call to action, trust signals, form, mobile experience. Then we intervene on the entire technical scope, from the server to the browser: campaign URL caching, third-party scripts, media, fonts, form responsiveness. Fixes are deployed directly to your site, without interrupting your campaigns.
Comprehensive deliverable
03You receive a complete deliverable: each deployed fix and its justification, Core Web Vitals and PageSpeed Insights scores before/after intervention, an inventory of your third-party scripts and their cost, and our prioritized editorial and ergonomic recommendations, ready to be implemented by your teams or your agency. This will help sustain the gains and share them with your SEA consultant.
What do our experts do, concretely?
A CRO agency works on messaging and design, a SEA agency on ads and bids. In between, the technical part of the landing page often remains a blind spot: this is precisely our specialty. Our experts intervene on four fronts: the first screen, marketing scripts, campaign URL caching, and the conversion path. Each fix is deployed and then measured, never delivered based solely on a best practice.
A first screen displayed with priority
The visitor arriving from an ad decides in a few seconds whether to stay. Until the headline, offer, and call to action are displayed, they cannot be convinced: on mobile, every second of waiting is paid for in lost clicks.
We prioritize what builds the first screen: main visual, headline, call to action. Images in modern, well-sized formats, non-blocking font loading, critical CSS: your landing page's LCP takes center stage.
Marketing scripts under control
Google Tag Manager, Meta and LinkedIn pixels, consent banner, A/B testing tool, session replay, chat: a landing page quickly accumulates about ten of them. Each takes its share of the phone's processor, delays display, and slows down click reactions.
We audit every tag in your Tag Manager and every third-party script: useful or not, loaded at the right time or not. Essential scripts are deferred or loaded on the first interaction, duplicates and orphaned tags are removed. Your conversion tracking remains intact, and verified.
A cache that also serves your campaigns
Each Google Ads click arrives with a unique parameter in the URL (gclid), each Meta click with its own (fbclid). For most caches, both server-side and CDN, each of these URLs is a new page, to be generated entirely: your site's most expensive traffic often receives the slowest page. PageSpeed Insights will never show this, as its field data merges all variants of a page.
We configure the server, cache extension, and CDN so that campaign URLs (gclid, fbclid, utm, msclkid…) are served from the cache, just like the clean URL. The server response time (TTFB) for your paid traffic then aligns with that of your best pages, without loss of attribution in Google Ads, Meta, or GA4.
A frictionless conversion path
A form that's too long, a field that reacts with delay, a captcha that blocks, or a button that jumps when you tap: it's at the last moment that the most costly conversions are lost. We work on responsiveness (INP), layout stability (CLS), and accessibility, primarily on mobile.
Responsive form, chosen and loaded captcha to avoid slowing down, buttons that no longer move : we fix everything technical. For the rest (form length, labels, error messages, trust signals), we provide you with precise recommendations, based on our Opquast certified quality approach.

It is the set of improvements that increase the proportion of landing page visitors who complete the desired action: quote request, registration, purchase. It covers both content (message, offer, proof, call to action) and technical aspects (speed, responsiveness, stability, tracking reliability). Our specialty is to handle the technical aspects from end to end and document every fix, with precise recommendations on the content.
Yes, in two ways. Directly, because the landing page experience is part of the ad quality score and ranking, and Google explicitly recommends a fast page. Indirectly, because a faster page loses fewer visitors before loading and converts better: your cost per acquisition decreases, and automated bidding has more conversions to learn from.
We optimize landing pages built on WordPress, Shopify, PrestaShop, Drupal, or custom-developed, across the entire technical scope: server, cache, CDN, code, media, and scripts. For hosted landing page tools (HubSpot, Unbounce, Webflow…), we go as far as the platform allows, and we will frankly tell you its limitations. Your existing page is sufficient: we optimize it without starting over.
Landing page optimization costs €800 excluding tax. This is a fixed price package per optimized page, with intervention within a few days, which includes technical alignment, intervention across the entire technical scope, and exhaustive deliverables. Do you have several landing pages to optimize? The price becomes degressive as soon as they share the same technical stack: the content fixes then benefit all pages at once.
The gains depend on the starting point: a page that has never been optimized offers more room for improvement than a page that has already been carefully crafted. In our performance interventions, the observed orders of magnitude range from 20 to 55% less TTFB and 40 to 65% less LCP.
These technical gains translate into measurable business results, which are the real reason for optimizing: Dartfish thus recorded 12% more qualified leads after our intervention.
We never promise a figure before the analysis: the initial alignment is precisely used to estimate the real potential of your landing page before committing.
With pleasure, and that's even ideal. Your consultant knows your ads, your audiences, and your bids; we take care of what happens after the click, and we pass the deliverable to them so they can leverage it in their campaigns.
