When is a conversion optimisation agency worth it?

As soon as your main funnel produces enough conversions per week to decide A/B tests in reasonable time, and you have no internal capacity for analysis and delivery. With low traffic, qualitative analysis using heatmaps and session replays usually produces insight faster than a testing programme.

What does conversion optimisation by an agency cost?

Monthly retainers, fixed project fees for audits or performance-based models are common. Ranges differ widely by scope and delivery depth – always ask about the planned test frequency and whether development is included.

Can I do conversion optimisation without an agency?

Yes. The first step is always understanding, not implementing. With heatmaps, session replays and funnel analysis you can see for yourself which step loses visitors. BigHoot adds AI insights that explain the likely reason and suggest a concrete measure.

Is BigHoot a conversion optimisation agency?

No. BigHoot is software for conversion optimisation and GDPR-compliant tracking. Agencies use BigHoot as the analysis and reporting layer for client projects, while shop and SaaS owners use it in-house.

What data does a CRO agency need from me?

Access to web analytics, behavioural data such as heatmaps and session replays, and ideally revenue data per funnel step. Any processing of personal data requires a DPA with both the agency and the tool provider.
