Public Case Studies

For each case we publish the target, the challenge, what we did, before/after measured values (Google Search Console / GA4), and external factors — real measurements only. We currently list 2 cases, our own site and a community site we operate; customer case studies will be added once we have publication consent.

Multiple initiatives and external factors overlapped during each period, so we do not claim individual actions caused the numeric changes. See each case's "external factors and limitations" section.
