Two anchor cities, two keyword sets, and no such thing as a Metroplex ranking
Dallas and Fort Worth return different local results for the same query, so one averaged keyword report hides both markets at once.
Local rankings are computed from where the searcher is standing. An office near Uptown can look strong from Lakewood and be invisible from Arlington. Any tool that reports a single position for the metro is averaging away the only thing you needed to know.
Track by point instead. Pull rankings from a grid of locations across Dallas County, Tarrant County, Collin County and Denton County. Patterns appear quickly. The same page wins in one county and never surfaces in the next one over.
Then make a decision most firms avoid. Pick the counties you actually want files from and write for those places by name. One office does not own four counties of search, and pretending otherwise sets a standard nobody can meet.
Claiming the whole Metroplex also buys you the wrong calls. People assume an office twenty minutes away. Being specific is generally cheaper than being everywhere.
