What to Look for in a Google Ads Agency (And Red Flags to Avoid)
Not all Google Ads agencies are built the same. Here's how to separate the ones that move business metrics from the ones that polish dashboards.
A Google Ads agency manages your paid search investment on Google's ecosystem - Search, Shopping, Display, YouTube, and Performance Max. Done well, it's one of the highest-ROI growth channels available. Done poorly, it burns budget and creates the illusion of marketing activity without revenue outcomes.
TTGC's growth team manages Google Ads campaigns alongside brand and SEO work, and the industry has seen what separates agencies that deliver from those that don't. Here's the unfiltered version.
For pricing expectations, read PPC management cost for a cross-platform benchmark. And if you're evaluating paid search alongside social media management, the social media agency guide covers the organic and paid social side.
What a Strong Google Ads Agency Actually Does
Audits the existing account before recommending changes - no "we'll rebuild everything" on day one without evidence
Establishes conversion tracking (including enhanced conversions) before spending
Maintains documented negative keyword lists, updated at least monthly
Runs structured creative tests with clear hypotheses, not random ad variation
Aligns ad copy to landing page messaging - reducing Quality Score penalties
Reports on CPA, ROAS, or revenue - not just impressions, clicks, and CTR
Red Flags That Are Disqualifying
They can't tell you who manages your account until after you sign
Case studies show only CTR or traffic increases - no revenue or CPA data
The account stays in their MCC after the engagement ends (you don't own your data)
They pitch Performance Max as a solution without explaining how they'll guide the algorithm
They charge percentage-of-spend with no fee ceiling and no commitment to increase work as spend grows
Google Partner Status: Meaningful or Marketing Badge?
Google Partner and Premier Partner status requires passing certifications, meeting spend thresholds, and maintaining performance. It's meaningful as a baseline qualifier but not sufficient on its own - large agencies with hundreds of small accounts can hold Partner status while individual account quality varies widely. Ask to see results on accounts similar in size and vertical to yours.
"A Google Ads agency should be able to tell you, in plain language, why your CPA went up last month and exactly what they changed in response. If the answer is a 20-slide deck of platform graphs, something is wrong." - Mherie Vic Prevendido, TTGC
