How can we increase your store's conversion rate?
The conversion rate does not depend on a single factor. The product, the price, the traffic source, usability, trust, shipping costs, the ease of the checkout process… all of these factors influence the final decision.
For this reason, we do not implement isolated changes without first analyzing the context. Our e-commerce CRO process is data-driven and carried out in a step-by-step manner.
1. We track the customer journey
We review the analytics settings and analyze how users navigate from the moment they arrive at the store until they complete a purchase using heat maps (heat maps).
We analyze which channels attract visitors, which products generate interest, on which pages visitors abandon their sessions, and which devices present the most challenges.
2. Identifying Frictions
We prioritize the obstacles that may be affecting sales: unclear navigation, incomplete product listings, slow loading times, lack of trust, lengthy forms, or costs that are revealed too late.
Each optimization proposal is based on a specific hypothesis and its potential impact on the business.
3. A/B Testing
When traffic volume and conversion rates allow it, we can conduct A/B tests to compare alternatives and determine which changes lead to real improvements.
4. Checkout Optimization
We reviewed the shopping cart and checkout process to eliminate unnecessary steps and make it easier for users to complete their purchases.
We also analyzed the clarity of key aspects for users, such as shipping costs, available payment methods, guest checkout, error messages, and the mobile experience.
5. Cart Return
We design strategies to recover abandoned shopping carts and reconnect with users who have shown interest. The email marketing, automation, and remarketingcampaigns allow you to stay in touch in a relevant way, while always avoiding excessive sales pressure.
