When your Google Ads click-through rate decreases while impressions are increasing, it almost always points to a change in how your ads are being served. Google shows your ads more frequently for less relevant search queries – pushing your CTR down. This pattern is especially common with Broad Match keywords and Performance Max campaigns.

What happens when CTR drops while impressions rise

A declining CTR alongside rising impressions means Google is showing your ads to a broader audience. The algorithm expands ad delivery, which initially sounds like more reach. However, many of these additional impressions occur for search queries that do not precisely match your offering. Users see your ad but do not click – because they are searching for something else. This not only hurts your CTR but also degrades your Quality Score over time.

Why Google expands ad delivery

Google Ads maximizes impressions because the algorithm optimizes for click volume. Especially after automatic keyword expansions or switching to Broad Match, impressions increase significantly. Additionally, Smart Bidding dynamically adjusts bids and also bids on borderline search queries. For campaigns with target CPA or maximize conversions goals, Google aggressively tests new audiences – at the expense of your CTR.

Our recommendation for declining CTR

Review your search terms report and exclude irrelevant queries as negative keywords. Switch from Broad Match to Phrase Match or Exact Match to focus ad delivery. A CTR below 3% for search ads indicates a fundamental relevance problem. Also optimize your ad copy with specific call-to-actions and use ad extensions for better visibility.
