Where Agencies Really Add Value in Google Ads (& Where They Don’t)
Sep 17, 2025Bottom-of-funnel search is mostly automated. Agencies win by doing what machines can’t: setting the right business goals, shaping creative and offers, building full-funnel content, and tying results to CFO-level metrics (MER, NCAC, LTV, contribution margin).
Key takeaways
-
Search bidding is simplified; focus human effort before and after the click.
-
Align on one goal at a time (efficiency or scale), not both.
-
Build a full funnel with creative that matches each stage.
-
Find real buyer personas in niche communities and groups.
-
Fix offer + landing page first; bad pages kill good traffic.
-
Measure like a CFO: MER, NCAC, LTV, contribution margin.
-
Communicate how each campaign helps the whole account, not just its own ROAS.
-
If you DIY, nail conversion tracking and a clear offer first.
Why “set and forget” search isn’t where you win
Modern bidding (Target ROAS / Max Conversions) plus Google’s data means search optimization is less manual. That’s good—but it also means the edge moves elsewhere: strategy, creative, and measurement.
Where humans beat the algorithm
-
Pick the right trade-off: You can’t grow volume and improve ROAS at the same time. Choose a season (e.g., 90 days to grow, then 90 days to tighten).
-
Provide context the algo can’t see: seasonality, launches, inventory, tariffs, pricing shifts.
-
Creative that stands out: Test sharper headlines and angles. Don’t blend into AI-written sameness.
Build a full funnel (and the content to match)
-
Top: Shorts, YouTube, social posts—educate and entertain.
-
Mid: Case studies, comparison pages, demos—reduce risk.
-
Bottom: Search and branded terms—capture intent.
Sync messaging across channels so search “catches” the people you already warmed up.
Find real buyer personas in real communities
Join micro-communities (FB groups, Reddit, niche forums, Discords). Listen first. Pull the language, objections, and triggers your audience already uses—and feed that into ads and landing pages.
Offers and landing pages: fix these first
-
Clear offer and one primary CTA.
-
Modern, fast page with real proof (reviews, logos, stats).
-
If 1,000 qualified visitors produced zero leads, it’s not bidding—it’s the offer/page.

If you’re not using an agency (yet)
-
Conversion tracking set up correctly (or outsource this one task).
-
Compelling offer + solid landing page. Scaling comes later.
FAQ
Is search still worth it if it’s “set and forget”?
Yes—search harvests demand. Your edge comes from better creative, offer, and funnel, not bid micromanagement.
What’s the one thing to fix first?
Conversion tracking. If you can’t measure, you can’t improve—or scale.
How do I choose between growth and efficiency?
Pick one for the next 60–90 days. If you chase both, you get neither.
How do agencies add value beyond bidding?
They align business goals, craft offers and creative, build full-funnel content, and tie spend to MER, NCAC, LTV, contribution margin.
How do I find my real buyer persona?
Join niche communities where your buyers hang out. Listen for pains, language, and objections; use that in ads and pages.
My campaigns look “unprofitable.” Should I kill them?
Not always. Some campaigns assist others. Check account-level MER before cutting.
What creative tests should I run first?
Headlines with a bold angle, problem-solution hooks, and proof snippets. Aim for clarity over clever.
I’m DIY—what’s a simple setup?
Clean tracking → one strong offer/page → basic search + one top-funnel video/short → weekly creative tests.
