Conversion & digital marketing

Conversion optimization: more revenue from the same traffic.

You have visitors. You need customers. We measure where they drop off, test what works and build the winning variant straight into your site. Conversion optimization, Google Ads, tracking and marketing automation, all from one studio.

What we do

Digital marketing that starts with measuring, not with more budget

Most online stores convert only a few percent of their visitors, and watch the majority of carts empty out again. More ad spend does not fix that: you are buying more visitors for the same leaking funnel. We turn it around. First we make sure your measurement is right, with GA4, Consent Mode v2 and server-side tagging that keeps working after the cookie banner. Then we can see exactly where people leave.

Then we test. No opinions, but A/B tests on the pages that matter: product page, checkout, quote form. We build the winning variant straight into your site, because we design and develop it ourselves. No handoff to another agency, no ticket queue.

Google Ads, email flows and marketing automation in HubSpot or Klaviyo plug into the same data. Everything lives in your own accounts, with dashboards you can read yourself. Every month you know what a lead or an order costs, and what to improve next.

How we work

→ Process

How an engagement runs.

  1. 01

    Measurement check

    Week 1: we verify GA4, tags, consent and conversions. Whatever is broken gets fixed first. Without good data you are testing in the dark.

  2. 02

    Analysis & hypotheses

    Funnel, heatmaps, session recordings and customer interviews. Every opportunity gets an impact-and-effort score, so we start with the biggest.

  3. 03

    Testing

    A/B tests on 2 to 4 pages at a time, with sample size and duration set in advance. No test gets stopped early.

  4. 04

    Shipping

    Winners are built straight into your site or store. Losers are documented, because knowing what does not work is knowledge too.

  5. 05

    Scaling

    Ads, email and automation get the same yardstick. A one-page report every month: what we did, what it returned, what comes next.

Why RABZI

Why RABZI for this work.

01

Marketing and engineering in one hand

We build what we recommend. A winning variant is live the same week, not after 3 tickets at another agency.

02

Measurement that holds up

Server-side tagging and Consent Mode v2 are our default. Your numbers stay usable as browsers and regulation get stricter.

03

Everything in your accounts

GA4, Ads, HubSpot, Klaviyo: all in your name. If you ever stop working with us, you take everything with you, documentation included.

04

Fixed price per sprint

A CRO sprint has a fixed price and end date. Retainers can be canceled monthly after 3 months. Never a percentage of your ad spend.

05

Honest about what works

A losing test is reported as clearly as a winner. You get decisions, not pretty charts.

Frequently asked questions

Questions about conversion & digital marketing.

01How much does conversion rate optimization cost at RABZI?

A CRO sprint starts from €1,950 excl. VAT. It includes a measurement check, a funnel analysis with prioritized opportunities and the first 2 to 4 A/B tests, including shipping the winners. Growth combines CRO with tracking and marketing automation from €4,950. An ongoing program starts from €9,500, retainers from €750 per month. You never pay a percentage of your ad spend.

02When does conversion optimization make sense?

From roughly 5,000 visitors or 100 conversions per month you can A/B test reliably. Below that we use user research, heatmaps and proven patterns instead of tests, and we tell you so up front. If you have less traffic, SEO or Google Ads is usually the better first step, and we are happy to combine them.

03Can you manage our Google Ads?

Yes. We manage Search, Shopping and Performance Max for accounts up to several tens of thousands of euros in monthly spend. The account stays in your name and Google bills you directly. We charge a flat monthly fee, not a percentage. For very large accounts or social ads we work with a specialized partner.

04What is server-side tagging and do I need it?

With server-side tagging your own server sends measurement data to Google, Meta and other platforms, instead of the visitor’s browser. Ad blockers and browser restrictions then affect your data far less. Combined with Consent Mode v2, your data stays usable and GDPR-compliant. For online stores and advertisers spending from around €2,000 a month, it has become the standard.

05Do you work with HubSpot or other platforms?

We set up HubSpot, ActiveCampaign, Klaviyo and Pipedrive and connect them to your website, store and accounting. We choose based on what your people actually use, not on what the vendor sells. If you already have a system, we build on it rather than migrate.

06How quickly will I see results?

The measurement check and analysis are done in 2 weeks. The first tests run in weeks 3 and 4 and need 2 to 6 weeks, depending on traffic, for a reliable outcome. Expect the first shipped improvements within 8 weeks. Structural growth is a program of months, not a trick of days.
