What we will not do
We will not build you forty suburb pages with the name swapped out. Google calls those doorway pages, they are explicitly against its guidelines, and the usual outcome is that the whole set stops ranking — taking your real pages with it.
We also will not list an address you do not occupy. A virtual office in the CBD does not make you a CBD business, and Google Business Profile suspensions for fake addresses are common and slow to reverse.
What actually works
A complete Google Business Profile at your real location or service area, consistent business details wherever you are listed, a clear service-area page on your own site, and dedicated area pages only where you have something real to say: the type of work you do there, the travel involved, local projects, local conditions.
