Broad match, missing conversion tracking and no negative-keyword hygiene waste 40-60% of most agencies' ad budgets. Here's what a properly built account actually looks like.
Most Google Ads accounts we take over from another agency aren’t failing because of the platform. They’re failing because of the setup. And it’s almost always the same handful of mistakes.
Broad match keywords with no intent signals. A single ad group trying to cover every service you offer. No conversion tracking, so nobody actually knows which clicks turned into calls. Generic landing pages that send every visitor to the homepage instead of a page built for the exact thing they searched for.
Set an account up like that and you’ll waste 40–60% of the budget on clicks that were never going to convert. We’ve taken over accounts where more than 60% of spend was going to search terms that had nothing to do with the business. That’s not a platform problem. That’s a setup problem, and it’s fixable in the first few weeks.
A pre-launch negative keyword list running into the hundreds of terms, built before the campaign ever goes live. Weekly search-term audits so junk traffic gets cut before it burns real budget. Ad groups split by service, each one pointing to a landing page written for that specific search, not a generic homepage. And conversion tracking on calls and form fills from day one, so every dollar can be traced to an outcome.
The difference shows up fast. Across our client base, cost per lead drops an average of 38% within the first 90 days once an account is properly structured. Not because the algorithm suddenly got smarter, but because it’s finally being fed the right signals.
This is the question we get asked first, and the honest answer depends on your industry and location. But as a rough floor, most service businesses in metro areas need at least $1,500–$2,000 a month in ad spend to generate enough data for the algorithm to optimise properly. Below that, in competitive categories, you’re often paying for impressions without giving the account enough signal to actually learn.
One thing worth being clear on: a management fee and your ad spend are two separate things. Your budget should go straight to Google. Any agency taking a percentage of media spend on top has a built-in incentive to keep you spending more, whether or not it’s working.
Most campaigns start generating leads within the first week of going live. But the first 30–60 days is a learning phase. The algorithm is finding the right audience, and real optimisation happens on the back of real data, not guesswork. Cost per lead typically improves meaningfully in months two and three, once enough search-term and conversion data has come in to start cutting waste with confidence.
If an agency ever hesitates to hand over admin access to your own Google Ads account, that’s worth noticing. You should own the account outright. If you ever leave, you take the account, the data and the full campaign history with you. Nobody should be able to hold your ad performance hostage.
Google Ads works. What doesn’t work is a lazy setup dressed up as a strategy: broad match everywhere, no tracking, no negative keywords, and a report full of clicks and impressions instead of calls and quote requests. Fix the setup, and the platform does exactly what it’s supposed to: put you in front of people who are already searching for what you do.
