I run conversion rate optimization (CRO) for ecommerce stores, built on usability testing with real users instead of dashboard guesswork. 📈 Conversion rate optimization results from published case studies: 🔹 Fiorissimo: conversion rate optimization on the product selection flow. Conversion up 𝟭𝟵.𝟯𝟴%, revenue up 𝟲𝟵.𝟵𝟵%. 🔹 Boutique Party Shop: one conversion rate optimization audit surfaced 𝟵𝟮 issues. Conversion up 𝟯𝟬%, revenue up 𝟯𝟳%, orders up 𝟰𝟮%. 🏆 𝟮𝟬𝟮𝟱 𝗔𝗴𝗲𝗻𝗰𝘆 𝗼𝗳 𝘁𝗵𝗲 𝗬𝗲𝗮𝗿 for Ecommerce Development in Greece (Netstudio), where I direct the conversion rate optimization practice. ⭐ "First week we had enquiries and requests. Two months in, we are continuously growing the conversion rate. From us, thumbs up." - Lia Damigou, CEO of Extramarble, a Netstudio client. Published on the Netstudio testimonials page. That is the bar for every conversion rate optimization (CRO) and usability testing engagement I take. Most conversion rate optimization (CRO) advice is guesswork read off a dashboard. I watch real users. My team built Userfeel, a usability testing platform with 𝗼𝘃𝗲𝗿 𝗮 𝗺𝗶𝗹𝗹𝗶𝗼𝗻 testers in 𝟰𝟬+ languages. Product teams at IBM, Tesco, Target, and McKinsey run usability testing on it. Every conversion rate optimization engagement I lead runs on that same usability testing engine, so each conversion rate optimization decision rests on recorded user behavior, not opinion. 🏆 𝗧𝗥𝗔𝗖𝗞 𝗥𝗘𝗖𝗢𝗥𝗗 🌟 𝗥𝗲𝗴𝗮𝗹𝗶𝗻𝗮𝘀 (Fashion, Greece): conversion rate optimization plus a replatform. 𝟭.𝟱𝘀 mobile LCP, 𝟭𝟱 stores unified. 🌟 𝗚𝗦 𝗗𝗶𝗮𝗺𝗼𝗻𝗱𝘀 (Jewelry, AU): conversion rate optimization reset after three failed agencies. 𝟱𝟬𝟬𝗞 live diamonds. 🌟 𝗠𝗘𝗩𝗚𝗔𝗟 (FMCG, GR): B2B and B2C funnels on one codebase, conversion rate optimization on both. 🌟 𝗘𝘅𝗽𝗿𝗲𝘀𝘀 𝗣𝘂𝗯𝗹𝗶𝘀𝗵𝗶𝗻𝗴: 𝟮𝟲 sites consolidated, no data loss. 🌟 International conversion rate optimization and usability testing for 𝗕𝗮𝘆𝗲𝗿, 𝗚𝘂𝗰𝗰𝗶, 𝗜𝗕𝗠, 𝗗𝗲𝗹𝗼𝗶𝘁𝘁𝗲, 𝗥𝗮𝗸𝘂𝘁𝗲𝗻, 𝗧𝗿𝗶𝗽𝗔𝗱𝘃𝗶𝘀𝗼𝗿, 𝗙𝗼𝘂𝗿 𝗦𝗲𝗮𝘀𝗼𝗻𝘀, 𝗟'𝗢𝗰𝗰𝗶𝘁𝗮𝗻𝗲, 𝗢𝗳𝗳𝗶𝗰𝗲 𝗗𝗲𝗽𝗼𝘁. 🚀 𝗪𝗛𝗔𝗧 𝗜 𝗗𝗢 🔹 Conversion rate optimization (CRO) audits: expert review of your store or landing pages. You get a prioritised conversion rate optimization roadmap, in writing. 🔹 Usability testing and user interviews: real users on camera, thinking out loud on your site. The fastest source of conversion rate optimization wins. 🔹 Customer surveys: why buyers buy, in their own words, feeding the conversion rate optimization backlog. 🔹 A/B testing: each conversion rate optimization hypothesis instrumented in code, results gated by statistical confidence. 🔹 Landing page optimization: message, layout, and speed fixes. 🔹 Ecommerce conversion rate optimization on Shopify, Shopify Plus, WooCommerce, Magento, and custom storefronts. 🔹 Implementation: a 55 person in-house team ships the conversion rate optimization fixes. No gap between the CRO plan and the code. 🔹 Analytics: GA4 measurement built so every conversion rate optimization (CRO) gain survives scrutiny. 🎯 𝗪𝗛𝗢 𝗜 𝗪𝗢𝗥𝗞 𝗪𝗜𝗧𝗛 You run an ecommerce store or a lead generation site with real traffic. Ad spend climbs but conversion stays flat. You want conversion rate optimization grounded in usability testing evidence, not taste. Shopify, WooCommerce, Magento, or custom storefront: conversion rate optimization works the same on each, and CRO pays for itself fast. If you need a one-off banner tweak, I am not the right fit. Conversion rate optimization is a program, not a tweak. 🔄 𝗠𝗬 𝗣𝗥𝗢𝗖𝗘𝗦𝗦 Expert review first. Then customer surveys, user interviews, and usability testing. Then a findings summary with a prioritised conversion rate optimization roadmap. Then implementation and A/B testing to verify each conversion rate optimization gain. Each step of the conversion rate optimization program arrives in writing. That is how conversion rate optimization compounds: every cycle starts from usability testing evidence, not guesswork. That keeps CRO honest. 📞 Send your URL and your main conversion rate optimization concern. I reply within 12 hours with a first conversion rate optimization read. If CRO is not what you need, I say so.

What does a Convert - A/B tester do?

A Convert - A/B tester designs and runs controlled experiments within the Convert Experiences platform to measure how changes to web pages or applications affect user behavior. This specialist loads target URLs into the Visual Editor, creates distinct variations of page elements, and defines specific conversion goals to track performance against a baseline. The role focuses on configuring tracking scripts, launching tests, and interpreting statistical reports to determine which version drives more conversions.

  • Builds A/B experiments by loading target pages into the Convert Visual Editor and modifying HTML, CSS, or JavaScript to create variation content that differs from the original control version.
  • Configures conversion goals within the platform to define success criteria, ensuring primary metrics such as clicks, form submissions, or purchases are tracked accurately for each experiment variant.
  • Installs and verifies the Convert project code snippet on client websites to activate experiments, then runs A/A tests to validate the setup and establish a reliable conversion baseline before launching full A/B tests.
  • Analyzes experiment reports and metrics to interpret visitor data, identifies statistically significant winners or losers, and submits recommendations for next steps based on observed user behavior and goal completion rates.

How to hire a Convert - A/B tester on Upwork

Step 1: Post a job

Describe your testing needs in a few sentences and let Job Post Generator powered by Uma™, Upwork's Mindful AI draft a complete job post for the role. You can write a new post, update a saved draft, or reuse an existing post to start hiring.

  • Specify that the freelancer must create A/B experiments in Convert Experiences by defining control pages and variation content using the Visual Editor.
  • Require experience setting up goals to measure conversion criteria and installing the Convert project code snippet for accurate tracking.
  • Ask for proof of running A/A experiments to validate setup quality and establish a conversion baseline before launching live tests.

Step 2: Evaluate candidates

Look for portfolios that show configured experiments with clear goal definitions and documented results from Convert reports. Uma can run instant video interviews and build shortlists with side-by-side comparisons to help you assess technical fit.

  • Check for examples where the candidate interpreted experiment reports to identify winners and recommend next actions based on visitor and conversion data.
  • Verify they have activated experiments using the Convert tracking script and managed variants during active testing periods.
  • Confirm they understand how to use the Convert Developer Hub resources for SDKs and API references when custom tracking is needed.

Step 3: Interview your top choices

Discuss their approach to defining primary goals and how they handle variation configuration in the Visual Editor. Interviews can be scheduled and conducted within Upwork Messages with an immediate transcript and summary after each one.

  • Ask how they structure an A/A test to confirm measurement setup quality before starting a standard A/B or Split URL test.
  • Request details on how they define success metrics and ensure the primary goal drives reporting and winner selection in Convert.
  • Explore their process for reviewing experiment reports to determine if a variation outperforms the baseline control page.

Step 4: Agree on scope and begin work

Define deliverables such as configured A/B tests, documented goal definitions, and activated experiments ready for analysis. Use Upwork Messages and the contract workroom for communication and project management, plus identity verification, payment protection, hourly tracking, and project funds for security.

  • Milestone one should include the installation of the Convert project code and the creation of the initial experiment with defined variations.
  • Milestone two covers the setup of goals and the execution of an A/A validation run to confirm baseline behavior.
  • Final deliverables include the activated live experiment and a review of initial report inputs to guide follow-up actions.
