Optimization / Conversion rate optimization (CRO)

Maximize your site's performance thanks to data

Don’t settle for your website’s current conversions

Your website has goals, which are defined in Google Analytics as conversions: the sale of a product, the receipt of a contact form, a request for a demo, the subscription to a free trial, the download of a white paper, etc. CRO (Conversion Rate Optimization) increases the number and quality of the visitors to your website who will perform one of these actions. CRO also maximizes your ROI and ROAS (Return On Ad Spend).

You need our conversion rate optimization services, if:

  • You are not satisfied with the quality of leads generated by your website.
  • You think your return on investment could be better.
  • Your current agency does not demonstrate proactivity to optimize your conversion rates.

We act at different levels:


At the campaign level, we use all the data from your advertising platforms to generate the most qualified leads to your website, which will improve your conversion rates. For example, in Ads, keyword management is crucial to best qualify visits. We also use audience distribution and advertising content tests to improve our campaigns’ performance.


We conduct A / B testing on your website and landing pages to increase the number of visitors who will fill out a form or add a product to their carts. We test the content distribution on the page, images, animations as well as the text and colors of call-to-actions to find the best possible combinations.

Forms and conversion funnels

We also perform A / B tests of crucial pages that feature forms and other information that help bring leads down the sales funnel. In particular, we test the number of fields that are optimal for generating the most high-quality leads as possible. In addition, we ensure that conversion paths are frictionless on both mobile devices and desktops.


In case of lead generation, quantity is not necessarily a priority. We strive to optimize the quality of the leads we generate, which is why we pay particular attention to the lead-to-sales conversion rate and average sales values. In e-commerce, we also take into account average shopping carts, customer loyalty and product return rates in our optimization strategies.
