What these numbers are, and what they are not
Classification: supported, but private. The figures come from the Google Ads account and the reporting delivered to the client during the engagement. They were not audited by a third party, the client has not published a testimonial, and the comparison window and the exact conversion definition are not published here. A reader cannot verify them independently, and this page does not claim otherwise.
What a reader can check: the engagement and its dates are the same as stated on the results section of the home page and on Diego's LinkedIn profile. The methods listed are the standard ones for a competitive local-services account; nothing proprietary is claimed.
What is confidential and will stay so: the client's campaign structure, keyword lists, landing pages, lead volumes and revenue.
