02 / The measurement gap

A car-buying journey starts long before the final click

Someone can see a TV advert, read a review and research a model before returning to enquire. Reporting only the last click can miss the advertising and content that came earlier.

What you can see

Sophus3 connects available exposure and website records so you can examine what buyers did after advertising, including actions that happened before the enquiry.

Illustrative journey, not a tracked individual. Coverage depends on participating sites, media partners and the agreed measurement design.

03 / How Sophus3 measures the campaign

Connect advertising exposure with real automotive website activity

Our approach builds on eDataXchange, Sophus3’s automotive digital competitor benchmarking service, and specialist experience analysing online car buyers.

Agree the campaign and comparison

Choose the models, markets, media activity and observation period. Agree which buyer actions matter and how exposed audiences will be compared.

What your team receivesA measurement plan before the campaign starts

Record exposure and website actions

Bring together available advertising-exposure records and Sophus3 website tracking for model research, configurations, stock searches and enquiries.

What your team receivesA consistent view of automotive buying activity

Match within a secure environment

Sophus3 uses IP matching in a secure clean room to connect advertising exposure with website activity. The matching scope, permitted data and coverage are agreed with each partner.

What your team receivesConnected records with agreed privacy and security controls

Compare behaviour and recommend changes

Compare exposed and non-exposed audiences where the study design allows. Weighted engagement scoring brings buying actions together, while individual measures show where interest progresses or stops.

04 / Published campaign evidence

Advertising influence you can see in buyer behaviour

Explore two published studies. Each uses its own comparison, so the figures describe different outcomes and should be read separately.

How to read these results

These are reported study findings, not a prediction for a new campaign or a count of vehicle sales. The public summaries do not provide full sample sizes, observation windows or uncertainty estimates. Agree those details and an appropriate comparison before assessing a campaign. A lead-form start is not a completed lead.
