To reduce irrelevant LSA leads, tighten your service areas and job types so your ads target only the customers you actually want. Review your LSA profile and remove services you do not offer or do not want to promote.
Also monitor your lead history to identify patterns. If you consistently receive leads for the wrong service, location, or customer need, adjust your targeting accordingly. Make sure your business information clearly matches the services you provide.
For leads that are clearly invalid, such as spam, wrong numbers, or requests outside your service area, use Google's lead dispute process when eligible.
The goal is to focus your LSA targeting on the services and locations that produce qualified, profitable customers rather than simply maximizing lead volume.
