Your LSA impressions can drop even when your budget stays the same because budget is only one factor affecting ad visibility. Changes in local search demand, competition, service areas, business hours, reviews, responsiveness, or your profile can all affect how often your ad appears.
Seasonal changes can also reduce the number of people searching for your services. If competitors become more active, your share of available leads may drop as well.
So, don’t assume you need a bigger budget right away. Check your impressions alongside lead volume, competition, targeting, and profile performance to figure out what actually changed.
