What are Invercargill plumbers getting wrong?
90% show no visible review/update date
The fix: On time-sensitive pages, display a maintained review date so readers can assess currency.
15% have no structured data at all
The fix: Add LocalBusiness JSON-LD so AI engines can identify the business, its services and its area.
0% triggered the historical rules-v1.0 crawler check
The fix: Run the current v2 check before changing robots.txt. It separates discovery, user-fetch, training and model-control crawlers, then shows the exact rule evidence for the checked page.
0% appear to rely on JavaScript for main content
The fix: Put the key service and location content in the initial HTML so it does not depend on a later rendering stage.
