Evaluating evidence
Paid-search evidence
A paid-search example needs the full cost and the definition of the reported outcome.
Case study status
No permissioned client case study is published for this topic in this review. There are no client names, outcome figures or testimonial claims to verify here.
What a useful example would show
Ask for the campaign period, relevant spending, management scope and accepted inquiry or purchase definition. A click count does not establish a useful customer outcome.
Keep cause and context separate
An observed change after a release does not establish that the release caused it. Retain the original evidence, comparison dates, limitations and permission to share the work.
