Impact analysis
What do the figures show before and after a change? We compare up to five metrics and review other influences that limit the conclusions.
What has changed since the initial diagnosis? We review agreed metrics, implemented changes and the next tasks.
Requires an existing initial diagnosis.
Your enquiry is non-binding. An order is created only when you accept our quotation ; this also applies to the quarterly review.




Since the initial diagnosis, some changes have been implemented while other tasks remain open. The quarterly review compares this state with the documented starting point and updates priorities.
The baseline is that agreed starting point. Without it, meaningful comparison lacks a reference. The package therefore requires an existing initial diagnosis. Each quarter, agreed metrics and implemented changes are considered, and next priorities are recorded in writing.
A review is not a complete new investigation of the entire website. It examines the agreed section, asking which assumptions still hold, which tasks are complete and what available data shows. A changed metric is not automatically attributed to the latest design change.
You receive an updated task list with reasons. If no changes were implemented or data does not permit comparison, we clarify which further review is useful.
Some recommendations are implemented, but comparison with the initial diagnosis is missing. We return to the documented starting point and examine what has changed.
New copy, a campaign and technical changes occur in the same period. We consider agreed metrics alongside this change history to interpret differences.
The previous task list is complete and several new ideas are available. Using the baseline, the review examines which question takes priority and what data is available.
We use the initial diagnosis, agreed metrics and changes implemented since then. Where changes were not documented, we record how that limits comparison.
We compare the agreed data with known changes. A notable curve alone does not prove an action caused it.
The result records next steps and open checks. The quarterly price includes neither implementation nor constant availability; the written follow-up round concerns the review.

After the review, record which recommendation you act on and when you publish the change. Include postponed tasks too. This history, together with metrics, forms the basis of the next comparison.
For deeper evaluation of one documented change, impact analysis is the related service. Work already included must not be charged twice for the same period and subject. Scope is compared before an additional commission.
Which decision depends on the figures? Note the metric, analytics tool and known changes during the period. We clarify these together after receiving your enquiry.
You do not need to provide credentials or full exports yet. We first agree which data is needed and how it can be supplied.
What is included, what do you need and what happens after your enquiry?
The process in detail →This support requires an existing, agreed baseline. If no starting point is documented, we first clarify which initial investigation suits the project. The review does not replace that foundation.
No. This service also begins with a non-binding enquiry. Start date, duration and further terms of recurring cooperation are clarified before a binding quotation. The displayed amount applies per quarter.
One agreed review and its follow-up round are included. Code development, unlimited design work and constant availability are excluded. New tasks are scoped separately.
A clear overview of relevant changes with their timing and purpose is helpful. Known campaigns or changed measurement definitions can provide context. This concerns the agreed question, not an unlimited collection of all internal activities.
No. The review builds on the existing baseline and considers agreed metrics and changes. If new questions need a fundamentally different investigation scope, this is identified and defined separately. The quarterly package is not a repeated full audit.
Review dates, start and contractual terms are set only in the written quotation.
A suitable initial diagnosis and documented baseline An overview of changes actually implemented Start date, duration and cancellation terms are recorded in the written quotation Credentials must not be included in the enquiry. Details are agreed only after written commissioning.
One written follow-up round is included. The service scope lists the analyses, designs or technical changes covered by the package. We agree additional work with you before it begins.
