Clicks Without Calls: A Paid Search Specialist on What Google Ads Audits Usually Reveal
When a Google Ads account produces traffic but the phone stays quiet, the instinct is often to blame the budget or the landing page. According to paid search specialist Colby Diehl, the real constraint frequently sits somewhere less obvious: whether the campaigns are even showing up in the auctions that matter. In this interview, Diehl walks through a dental practice case, the factors he sees overlooked in common Google Ads advice, and the changes owners reach for first when leads dry up.
The dental practice that was buying clicks it couldn't convert
Diehl describes a specialized dental practice generating clicks through Google Ads but struggling to turn that traffic into patient inquiries. An account audit pointed away from the usual suspects.
He said "the issue wasn't necessarily the budget or landing page experience" — instead, "the campaigns weren't participating in enough relevant search auctions to capture existing demand."
Several structural factors were limiting visibility: restrictive keyword targeting, geographic and ad scheduling limitations, and a Maximize Conversions bidding strategy running on very little historical conversion data. Together, these prevented the campaigns from using their full advertising budget.
The fix was a rebuild rather than a tweak — campaign restructuring, keyword optimization, refined targeting, and bidding adjustments. The result was an increase from 2 to 14 recorded conversions while cost per conversion dropped 68%.
His takeaway reframes the whole diagnostic: "Sometimes what appears to be a conversion problem is actually a search visibility and campaign structure problem."
What the standard advice leaves out
Much of the guidance available online about clicks without leads focuses on ad copy and landing pages. Diehl argues two other factors consistently get overlooked.
The first is search intent and where a prospect sits in their customer journey. As search becomes increasingly AI-driven, he says understanding intent matters more than ever. Targeting broad audiences or bidding on keywords simply because they relate to a business is no longer sufficient — keywords, ad messaging, and the landing page experience need to match what the user is actually looking for, particularly when they are ready to act rather than still researching or comparing options.
The second is geographic relevance, which matters especially for local businesses. Someone may click an ad for a service they need, but if the business is farther away than they would realistically travel, that click is unlikely to become a customer.
His summary of effective optimization: "reaching the right person, at the right stage of intent, in the right location, with a message that gives them a compelling reason to convert."
What owners change first — and why it often doesn't help
When calls stop coming, Diehl says owners tend to reach for one of two levers: increasing the Google Ads budget, on the assumption that more spend produces proportionally more leads, or switching to a Maximize Conversions bidding strategy because conversions are the goal.
Neither guarantees better performance. More spend won't generate more qualified leads if campaigns aren't aligned with search intent, and automated bidding can struggle to optimize when conversion data is limited or unreliable — a point worth understanding given how much automated bidding depends on signal quality.
Diehl's approach is to diagnose the underlying constraint before recommending changes, evaluating search demand, keyword performance, auction visibility, conversion tracking, and the landing page experience.
He said "successful PPC management isn't about spending more or making changes for the sake of optimization" — it's about "making informed decisions that improve conversion efficiency and produce measurable business results."
The common thread
Across all three questions, Diehl returns to the same principle: paid search isn't fundamentally about generating more clicks, raising budgets, or constantly adjusting settings. It's about understanding customer intent, identifying what limits performance, and making data-driven decisions that create measurable business value.
His stated philosophy: "diagnose first, optimize with purpose, and measure what actually moves the business forward."

Practical takeaways
- Audit visibility before budget. If campaigns aren't entering enough relevant auctions, more spend won't fix the lead flow.
- Check the structural limits. Restrictive keyword targeting, tight geographic and scheduling settings, and automated bidding on thin conversion data can all suppress delivery.
- Match message to intent stage. Keywords, ads, and landing pages should align with whether a searcher is researching or ready to act.
- Respect geography. For local businesses, a click from beyond a realistic service radius is unlikely to convert.
- Diagnose before changing. Evaluate search demand, keyword performance, auction visibility, conversion tracking, and landing page experience before adjusting spend or bidding strategy.
