Tracking exact keyword performance is essential if you want to optimize your ad spend effectively. While campaign-level stats give you a broad view, they can hide underperforming or overperforming keywords that are driving the real results.
By reviewing keyword or search term reports regularly, you can identify which terms are converting, which are wasting budget, and adjust bids or match types accordingly.
This allows you to move top-performing search terms into exact match campaigns for tighter control and better ROI, rather than relying on general metrics that may not tell the full story.
