CRO and personalization are still a young discipline for most online businesses. Companies have largely accepted that improving the customer journey pays off, but many still underestimate the resources it takes. We are convinced that a personalization project only succeeds when human and technological resources work together. This article looks at the first half of that equation in detail: the key roles in an effective personalization team, based on the experience of Gravity Field — a vendor of A/B testing and personalization solutions with its own consulting team.
Why you need a dedicated personalization and CRO team
There is more than one way to run a personalization and conversion optimization programme. Marketing and product directors often assume it is enough to plug in a good technology platform and assign one person to launch campaigns — but that is rarely the case.
It helps to picture the levels of personalization as a pyramid: content edits and A/B tests at the base, personalization and AI-driven personalization at the top.
With limited experience and limited resources, many eCommerce teams stop at the two bottom levels — tweaking individual page elements (banner copy or design, button colour, the discount shown in a pop-up) and running simple A/B tests. That approach never unlocks what personalization can actually do, and at best delivers marginal gains in conversion and revenue.
Some companies go further: they integrate a personalization platform or build their own technology. That is a step towards AI personalization, and it usually means relying on machine-learning capabilities — product recommendations based on an affinity profile, predictive targeting. Such solutions materially improve the odds of success, but used ad hoc and without control they may fall short of expectations, or in the worst case work against you.
Affinity profile — a set of personal preferences built from how a user behaves on the website or in the mobile app.
Predictive targeting — an AI engine that identifies the best “hypothesis — segment” combination and forecasts the uplift you would get from scaling it.
The way to maximise personalization uplift is to combine artificial and “natural” intelligence: to keep hunting for insights, to use customer data from many online and offline sources, to build custom campaigns with non-trivial logic, and to align AI algorithms with business logic. That work takes a range of specialists with deep, narrow expertise, and the right people are not always available in-house or through an agency. But this is the approach that gives the platform the greatest impact on business metrics and makes the project cost-efficient.
Working for results: tasks and roles in the project
So who do you actually need to build a complete, effective personalization team? At Gravity Field we believe that team should be assembled on the personalization vendor’s side: we collect the strategic, technical and managerial workload and staff a dedicated role against each part of it.
- Personalization manager
The project lead and the main point of contact for platform customers. This is the person who provides strategic and project management: they build the roadmap and own its delivery — launching campaigns on schedule and making them perform. A personalization manager needs deep expertise in the client’s business and broad expertise in how the platform and everyone else on the project works. At Gravity Field we usually hire for this role people with relevant client-side experience — they understand the needs of a specific vertical, can propose the most effective solutions and see them through to implementation.
- Technical consultant
A specialist with deep expertise in the technology and in how it is applied in practice. The technical consultant joins at the integration stage and supports the customer on technical questions for the life of the project. At Gravity Field we look for engineers with strong communication skills — it matters that the consultant not only understands the subject, but can also explain the finer points of working with the platform to technical and non-technical colleagues alike.
- Analyst
One of the most important roles on the project, and the one that sits under the hood of every successful campaign. It is the analyst who brings the personalization manager the insights that turn into strong hypotheses and shape the project roadmap. Gravity Field analysts are equally comfortable with data from the personalization platform itself and with what third-party tools can offer. That expertise leads to more objective conclusions about campaigns and uncovers new segmentation opportunities.
- UX designer
The specialist who designs the visual side of every experiment. What matters in this role is not only taste, but a solid grasp of how design connects to business metrics. Gravity Field UX designers are professionals with UX strategy skills, or with experience working alongside UX strategists.
- Frontend developer
Essential once a personalization project moves beyond template-based A/B tests into experiments with complex custom logic. This is the person who implements what the UX designer proposes and adapts the platform’s default capabilities to the specifics of a given business. At Gravity Field we look for more than talented coders here — we look for people who can find non-obvious solutions for each customer’s needs.
- Content manager
The operational specialist responsible for configuring, QA-ing and launching campaigns. The hands of the project, and the rapid response team when an experiment needs an urgent edit or an A/B test has to be stopped. Companies running the platform on their own often merge the content manager and personalization manager roles to save budget, which can hurt results. Gravity Field recommends keeping them separate — it raises both the quality and the number of campaigns you can launch.
The icing on the cake: the client-side team
Whether you hand the personalization project to the platform’s dedicated team or assemble your own outsourced team, your internal and external teams have to work well together. Decide which of your own people will join the personalization project team and interface with the vendor. In my experience the platform team usually works with a marketer, a product manager and a project manager. The marketer builds the long-term marketing strategy that the personalization programme fits into. The product manager keeps changes consistent across the whole product lifecycle. The project manager handles planning and resource management on the client side.
You can put project ownership on your side in the hands of one person who becomes the business sponsor for the personalization team, or you can involve a small cross-functional group. The key to success is not the number of people involved, but how engaged they are and how committed they are to the outcome.
