Broad match + Smart Bidding vs Exact match + manual: the real tradeoff
Google keeps pushing broad. Here's when each wins.
Broad + Smart Bidding
👍 Finds query variants you'd never build out manually — great once you have 30+ conversions/mo to feed the algorithm
👍 Less keyword grooming
👎 Burns budget on garbage queries for weeks before it 'learns'; search-term reports get ugly
👎 You lose granular control of negatives early on
Exact + manual CPC
👍 Predictable spend, tight search terms, easy to defend ROI
👎 Caps your reach; you miss long-tail volume
👎 Heavy maintenance — endless negative lists and new keyword adds
Verdict: Exact/manual until you have stable conversion volume, then test broad on your proven winners with tROAS.
Best for: Exact for thin-budget arbitrageurs, broad for accounts with real conversion data to train on.
