Tag the jurisdiction before you tag the job
Until every inquiry is labeled District, Maryland or Virginia, your conversion rate is measuring two different businesses at once.
Add jurisdiction as the first field on whatever your office uses to log calls. Not the full address, just which of the three markets it sits in.
Within a month you will usually find that one jurisdiction converts far better than the others, and that a chunk of every week is spent on calls nobody can serve. Both of those are actionable and neither is visible in a blended booking rate.
It also tells you where your marketing is misaimed. A high volume of unserviceable inquiries from one area usually traces back to a targeting setting or a vague coverage line on the site.
Keep the tag consistent. A field that half the team fills in produces worse decisions than no field at all.
