Why High-Intent Exact Match Outperforms Broad Match on Sub-$10K Budgets

The Broad Match Trap on Lean Budgets

Google aggressively pushes Smart Bidding combined with Broad Match keywords. While Broad Match works well for enterprise accounts spending $100K+ per month with thousands of conversions, applying it to sub-$10K monthly accounts often leads to budget dilution on irrelevant queries.
