Conversion rate optimization agency, no guesswork.

What a conversion rate optimization agency does

Conversion rate optimization (CRO) means turning more of the visitors you already have into customers. A conversion rate optimization agency finds where people drop out, works out why and tests a fix against your current page. We combine heatmaps and recordings of real visits with your analytics, rank the test ideas by expected impact and effort, and calculate up front how many visitors each A/B test needs.

Our conversion rate optimization services cover the whole path, from first click to checkout or contact form, not just one landing page. Every winner gets built into your website and every loser gets written up. Results are reported as extra euros per visitor, not as a conversion rate on its own, so you see what each change is worth.

Why companies choose LASEO for CRO

LASEO is a 100% SEO agency, and that changes how we run CRO. A test done wrong can hurt your rankings: showing Google different content than your visitors see, or replacing a heading that matches what people search for. We plan every test with our technical SEO team before it goes live, so the pages that bring in your organic traffic keep it.

You work with senior specialists, not a junior with a testing tool. We require 95% statistical confidence before we call a winner, and we tell you honestly when your traffic is too low for proper testing. In that case we switch to research such as a UX audit, or we tell you that growing your organic traffic should come first.

Conversion rate optimization for visitors from AI search

More and more buyers ask ChatGPT, Perplexity or Google's AI Overviews before they ever click. When they do click, they often land deep in your site with one specific question. CRO makes sure that page answers it and makes the next step easy, and with AI SEO we make those same pages easy for AI tools to read and quote.

Before we call a winner, we check the result per group: mobile or desktop, new or returning, and visitors from Google, ads or AI tools. That way you see whether traffic from AI search actually converts, and which pages need work first.

Conversion rate optimization, explained without the design-studio fluff

When you hire a CRO agency, you are buying the capacity to run tests, the discipline to read them correctly and winners that actually end up in your website. That is different from hiring a design studio (which delivers a new look) or a growth marketer (who brings in more visitors). Think of it as a part-time head of experimentation: a senior specialist who owns conversion alongside your team.

A/B testing vs multivariate testing

An A/B test compares one new version against your current page. A multivariate test tries many combinations of elements at once. Most companies should run A/B tests 90% of the time, because very few sites have enough traffic for a multivariate test to give a reliable answer. We tell you which one fits your traffic, instead of selling you the one that sounds advanced.

How many visitors a test needs to be trusted

A result is statistically significant when it is very unlikely to be down to chance. That takes enough visitors. A test on 200 visits and a 12% conversion rate cannot reliably show a 10% improvement within three months. Before a test starts, we calculate how many visitors it needs and tell you up front whether it is worth running with your traffic.

Heatmaps vs session recordings

Heatmaps show where all your visitors click and how far they scroll, which tells you what gets attention at the top of the page. Session recordings replay the visits of individual people, which helps explain why visitors drop out at one specific step. We use both, because neither is enough on its own.

Fixing the obstacles vs a full redesign

A friction audit finds the three to five small obstacles that cost you the most sales: slow form fields, forced account creation, confusing trust signals, unclear shipping costs. A redesign changes everything at once, so you can never tell which change helped or hurt. Fixing the obstacles is faster and gives results you can prove.

CRO vs SEO tradeoffs

A test done right does not hurt your SEO. A test done wrong can: showing Google different content than your visitors see, replacing the main heading that matches what people search for, or removing internal links that help other pages rank. We plan every test with the SEO team before it goes live, so both channels stay intact.

What to expect from the first 90 days

First 30 days: the friction audit, the list of test ideas and the test setup. Days 30-60: the first two tests go live and the first results come in. Days 60-90: a second round of tests and the first winner built into your website. In months 4-6 the gains start adding up, once three to five winners are live.
