Your LSA ranking can drop when the factors Google uses to match and rank local service businesses change. Common reasons include increased competition, changes in local demand, weaker review activity, slower response times, changes to your service area or business information, and budget or account changes.
Start by comparing your current performance with the period when you ranked better. Check your reviews, lead volume, service areas, business hours, budget, and responsiveness, and look for any recent account changes. Also check whether competitors have become more active or whether customer demand has shifted.
A ranking drop does not always mean you need a bigger budget. First identify what changed, then fix the factor that is actually limiting your visibility.
