Imagine a Melbourne plumber whose homepage lists every job, while blocked drains, hot water and gas work have no clear page owners. Calls are counted, but nobody records which service or page produced them.
Month one should establish measurement and page ownership. The next block of work can improve the priority service pages, connect them to useful category pages and fix profile or citation details that are genuinely wrong. Only then does it make sense to judge query movement and enquiry quality.
At month six, the useful question is not "Is the business number one everywhere?" It is "Which service pages gained qualified visibility and enquiries after the dated changes, and what deserves the next investment?"
