What is Convertize?
Convertize is a conversion rate optimization (CRO) agency that combines analytics with behavioral psychology to help businesses turn more website traffic into revenue. Its stated focus is growing revenue without increasing ad spend, by finding and fixing friction points in the customer journey.
What the agency actually does
According to its site, Convertize works across several areas:
- CRO audits — full website reviews that flag usability and content issues and propose concrete fixes
- PPC audits — reviews of paid Google and social media campaigns
- User-behavior analysis — heat maps and session recordings to see how visitors actually move through a site
- On-site surveys — gathering direct input from users
- Optimization work — sharpening value propositions, landing pages, ad copy, and SaaS onboarding
The agency's method, described in its book Smart Persuasion, applies research on attention, association, and memory to make sites more persuasive. In practice, that means structuring pages for "cognitive ease," reducing ambiguity, and using neuromarketing effects to nudge decisions. Analytics is used to identify when and where decisions happen, then content is adjusted to lower cognitive load.
Convertize states it works with businesses across Europe and the US, and its listed experts include Philippe Aimé and Jochen Grünbeck. Its A/B testing platform has been acquired by Glassbox, so the current business is the agency service rather than the testing tool.
Who it suits
This is a fit for marketing or product teams with meaningful traffic but weak conversion — for example, an ecommerce brand whose ad clicks aren't turning into purchases, or a SaaS company with a leaky onboarding flow. Because the work is project-based and audit-led, it tends to suit teams that want outside expertise rather than a self-serve tool.
A practical next step
Before contacting any CRO agency, write down your current conversion rate, your monthly traffic, and the single step in your funnel where you suspect the biggest drop-off. That gives you a concrete basis for judging whether a proposed audit addresses your actual problem. If you want to compare options first, CXL publishes CRO training and research, and Nielsen Norman Group offers usability guidance that can help you evaluate an agency's recommendations.
How much does a Convertize CRO audit or optimization project cost?
Convertize publishes indicative starting prices on its own site: a CRO audit from 4,800 and optimization work from 12,300 (currency not stated in the page material). Treat these as entry points rather than fixed quotes — the final figure depends on scope, number of pages or templates, ad accounts reviewed, and how much implementation the agency handles.
What the two tiers typically cover
| Engagement | Stated starting point | What it includes | Best suited to |
|---|---|---|---|
| CRO audit | from 4,800 | Full website audit flagging usability and content issues with concrete fixes; PPC audit of Google and social ads; user-behaviour analysis via heatmaps and session recording; on-site surveys | Teams that want a diagnosis and a prioritised action list they will implement themselves |
| Optimization project | from 12,300 | Value proposition work, plus ongoing testing and optimization of pages and journeys | Teams that want the agency to plan and run the improvement work |
A useful way to choose: if you have in-house design and development capacity and simply lack an evidence-based roadmap, the audit tier is the cheaper route to value. If your bottleneck is execution — nobody has time to run tests and rewrite propositions — the optimization tier is where the money actually moves revenue. Ask which deliverables are included at the starting price and which are billed as add-ons, since audits that expand from a handful of templates to a full site can shift the number substantially.
A concrete scenario
A B2B SaaS company spending heavily on Google Ads but converting few trials might start with the audit: the PPC audit surfaces mismatches between ad copy and landing pages, while heatmaps show where trial sign-up forms lose people. From there, they can either fix the top issues internally or move to an optimization project for the value proposition and onboarding flow.
Next step
Before requesting an estimate, write a one-page brief: your monthly traffic, main conversion goal, number of unique templates, ad spend, and whether you can implement changes yourself. That brief is what determines whether you land near the lower or upper end of either tier. For general comparison of agency pricing models, CXL and Conversion publish CRO resources and benchmarks that help you sanity-check any proposal.
How does Convertize use psychology and behavioral insights to improve conversion rates?
Convertize builds its conversion-rate optimization (CRO) work around what it calls "Smart Persuasion": a method that pairs analytics with psychology and behavioral economics. The premise is that analytics shows when and where decisions happen, while behavioral research explains why visitors hesitate. The agency then uses that combination to make pages easier to act on.
The psychological levers it applies
From the page evidence, the method draws on research into attention, association and memory, and organizes the work around three practical moves:
- Structuring sites for cognitive ease — reducing mental effort so visitors can process the offer quickly.
- Shaping the user experience to cut cognitive friction and ambiguity — removing unclear wording, competing messages and unclear next steps.
- Applying neuromarketing effects — using persuasion principles to nudge decisions rather than simply restating features.
The stated goal is revenue growth without increasing ad spend — the assumption being that the same traffic converts better once friction is removed.
How the analysis side feeds the psychology
Convertize's CRO audit and optimization services connect behavioral insight to concrete page elements. Its stated audit activities include:
- Full website audits flagging usability and content issues, with proposed fixes
- Paid-search and social ad reviews (Google Ads and Facebook Ads conversion audits)
- User-behavior analysis using heatmaps and session recordings
- On-site surveys to collect visitors' own explanations
The practical logic: session recordings and heatmaps reveal where people stall or drop off, surveys capture the stated reason, and the psychology framework supplies a fix — for example, rewriting a value proposition so it is specific and urgent rather than generic. The page also names value proposition work and SaaS onboarding among the optimization areas.
Who this suits, and a trade-off
This approach fits teams with meaningful traffic that already converts at a low rate — the kind of business where a better argument beats a bigger budget. It is less obviously useful for a site with almost no visitors, where the constraint is reach rather than persuasion.
The trade-off is that psychology-led changes are hypotheses, not guarantees. That is why the pairing with heatmaps, session recordings and surveys matters: those tools give you evidence about whether a change actually moved behavior, instead of leaving you to rely on the theory alone.
A practical next step
Before commissioning an audit, write down the two or three pages where you suspect the biggest drop-off, and one sentence on what you think visitors misunderstand there. Bring that to a free CRO strategy call — the page describes a call with a senior CRO expert followed by a joint plan and audit — and use the conversation to test whether the agency's diagnosis matches yours. If their first questions are about behavior and decision points rather than only design, the method is probably a fit.
For a second opinion on the behavioral side of the method, the agency's founders, Philippe Aimé and Jochen Grünbeck, are listed as authors of Smart Persuasion; the book is a reasonable way to judge whether the underlying thinking suits your team before you commit to a project.
What does Convertize's process for a CRO project look like from first call to implementation?
Convertize describes a three-step start before any optimization work begins: a free CRO strategy call with a senior CRO expert, an assessment in which you explain your site and challenges, then joint planning of a website audit or CRO project. Implementation follows from that audit or project scope rather than starting immediately.
The stated first-call-to-implementation path
- Strategy call — a senior CRO expert calls at your convenience; the company presents this as free.
- Situation assessment — you describe your website, project and challenges so the expert can judge what is needed.
- Joint planning — you agree on a website audit or a CRO project, which is when work on revenue growth begins.
What the audit and optimization stages cover
The page evidence lists these service components rather than a week-by-week timeline:
- CRO audit — full website audits highlighting usability and content issues with concrete solutions.
- PPC audit — top-to-bottom reviews of paid Google and social media ads.
- User-behaviour analysis — heat maps and session recording to study how visitors act.
- On-site surveys — survey tools to gather practical insight from users.
- Optimization work — value proposition definition, SaaS onboarding, landing pages and ad copy, plus analytics-led content changes to reduce cognitive load.
Their stated method is to combine analytics (when and where decisions happen) with behavioural economics research on attention, association and memory, then reshape content and experience to reduce friction.
How to judge whether this process fits you
The process is consultant-led and audit-first, so it suits teams that want diagnosis and strategic direction rather than a self-serve tool. Two practical checks before the first call:
- Bring analytics access and a clear revenue goal, since the assessment step depends on you explaining your challenges.
- Ask explicitly what the audit delivers (findings, prioritised fixes, or hands-on changes) and who implements them, because the page separates "audit" from "optimization" as distinct engagements.
If you prefer testing tools you operate yourself, compare with platforms such as VWO or Optimizely; if you want an agency to run the program, the Convertize path is closer to that model.
What results have clients achieved with Convertize's CRO services?
Convertize's own site highlights client outcomes mainly through qualitative case evidence and service scope, not a public results dashboard. The page names a CRO agency case study with Sunology and says the agency works with businesses across Europe and the US, but it does not publish specific uplift figures, revenue totals or testing win rates in the supplied material.
What the page actually claims
- Sunology case study is the one named client example on the page.
- The agency says its approach combines analytics with behavioural insights to turn more visitors into customers and increase conversion rates.
- It frames the objective as growing revenue without increasing ad spend.
- It offers audits and optimization work covering value proposition, SaaS onboarding, landing pages, Google and Facebook ad copy, usability and content issues.
Whose observations these are
The claims come from Convertize's own marketing page, including a note that its A/B testing platform was acquired by Glassbox. The page also names Philippe Aimé and Jochen Grünbeck as authors of Smart Persuasion, which the agency presents as the basis of its method. No independent review notes or video experiences are supplied here, so the strongest available evidence is the agency's own description of its work.
Practical way to judge results
If you are considering Convertize, ask for case studies with before-and-after metrics tied to a comparable business model. Useful specifics include:
- Baseline conversion rate and the measured change over a defined period.
- Whether the result came from an A/B test, a full redesign or a PPC restructure.
- The role of ad spend, seasonality and traffic mix.
- Which pages or funnels were changed, and what happened to revenue per visitor.
For a SaaS company, for example, a relevant proof point would be onboarding completion or trial-to-paid conversion, not just click-through rate. For an ecommerce brand, it would be add-to-cart or checkout completion rate. The page's audit and optimization services suggest those are the kinds of areas Convertize addresses, but the supplied evidence does not include the actual numbers.
A useful next step is to request the Sunology case study directly and ask for a reference call with a client whose funnel resembles yours. Compare that against broader CRO agencies such as ConversionXL or testing platforms such as VWO if you want to benchmark methods and results reporting.
How does Convertize's approach differ from other conversion rate optimization agencies?
Convertize's distinguishing claim is that it treats conversion rate optimization as applied behavioural science, not just as a testing or analytics exercise. Its page describes an approach "based on Smart Persuasion," drawing on psychology and behavioural economics—specifically research on attention, association and memory—and applying it to make websites more persuasive. Two named senior experts, Philippe Aimé and Jochen Grünbeck, are presented as authors of Smart Persuasion.
What that means in practice
The page frames the work in three layers:
- Analytics shows when and where decisions happen.
- Behavioural insight explains why visitors hesitate.
- Content and UX changes reduce cognitive load, friction and ambiguity, and use "neuromarketing effects" to lift conversions.
Services listed include full website CRO audits, PPC audits for Google and Facebook ads, user-behaviour analysis with heatmaps and session recordings, and on-site surveys. Optimization work covers value propositions and SaaS onboarding. The stated objective is to grow revenue without increasing ad spend—useful for teams whose paid acquisition costs are already high. The page also notes that the Convertize A/B testing platform was acquired by Glassbox, so the agency service is the focus here rather than the tool.
How this differs from typical CRO agencies
| Dimension | Convertize's stated approach | Common CRO agency pattern |
|---|---|---|
| Primary lens | Consumer psychology and behavioural economics | Analytics, testing volume, statistical significance |
| Starting point | Cognitive friction, attention, memory, persuasion | Funnel metrics, hypotheses, A/B test backlog |
| Deliverables | Audits, surveys, behaviour analysis, value-proposition work | Test roadmaps, experiment reports, tooling setup |
| Revenue angle | Grow revenue without more ad spend | Often paired with media buying or broader growth work |
The practical trade-off: a psychology-led engagement suits businesses with decent traffic but weak persuasion—unclear value propositions, confusing onboarding, or landing pages that get clicks but not sign-ups. If your bottleneck is simply too little traffic or a broken checkout, a purely experimental or technical CRO team may be a faster fit.
A concrete scenario
Imagine a SaaS company with steady trial signups but poor conversion to paid. A testing-first agency might run headline and button variants for months. Convertize's described method would start with session recordings and surveys to locate ambiguity in the onboarding flow, then restructure copy and sequence around how users actually form judgments—typically a more direct route to fixing a persuasion problem.
Decision criterion
Choose Convertize-style psychology-led CRO when your analytics are reasonably healthy but visitors still don't act, and you want messaging, positioning and user experience rebuilt around behavioural evidence. Compare it against analytics-heavy agencies such as CXL or testing-platform-led providers when your main need is experiment velocity rather than persuasion strategy. Ask any agency—including this one—for a past audit sample and how they measure revenue impact before committing.
