02 · Context

What we started with

The account was technically configured, but it wasn't built as a system for stable lead generation.

The core issue was a lack of focus in optimisation. There were too many Primary conversions - including secondary actions such as email clicks, map clicks and scroll events - and Auto Apply was switched on. GA4 data was underused, so the algorithm couldn't learn from real leads.

Search was inefficient: most keywords ran on broad match, driving irrelevant queries, higher CPCs and lower-quality traffic. Negative keywords were only partially built out, and budget was already being spent on terms with no results. Campaign settings ignored the local nature of the business - geo-targeting allowed impressions outside the actual service area.

03 · Problems

What was holding back growth

Unnecessary Primary conversions. Email clicks, map clicks and scroll events counted as leads - so the algorithm optimised for noise instead of real inquiries.

Broad Match without negatives. Irrelevant queries, rising CPCs and wasted budget on terms that never converted.

Geo-targeting outside real locations. Impressions served well beyond the venue's actual service area.

Weak PMax creatives & asset groups. Too few assets, no strong CTAs and irrelevant audience signals.

Partially-filled ads. Missing headlines, descriptions and sitelinks dragged down Ad Rank and CTR.

04 · Strategy

What was done - step by step

I had already worked with this client on Meta Ads before this. After that, I ran a full audit of the Google Ads account and built a step-by-step action plan.

1

Audit and cleanup

I removed unnecessary Primary conversions, disabled Auto Apply and set GA4 as the single source of truth - so the algorithm started learning from real leads instead of map and email clicks.

2

Search to collect signals

I launched Search campaigns across different segments, gathered real performance data by segment and query, and identified which queries produce quality leads. Historical data plus new signals laid the foundation for the move to PMax.

3

Rebuilding PMax from scratch

A new asset-group structure, strong audience signals and search themes, with internal competition eliminated. I added banners, ad copy with offers and clear CTAs - highlighting the venue's key advantages in the creatives.

4

Focus on Private Events + scaling

Once enough data had accumulated, I turned off underperforming segments and concentrated the budget on the best-performing one - Private Events. The system moved from testing to stable, predictable lead generation without increasing cost per lead.

Monthly performance

Already in the first month after the new structure went live, results changed dramatically - the account went from unstable to a predictable flow of leads, and held it for over a year.

06 · Summary

What was achieved

The account wasn't broken - it just lacked a system. Budget was being spent and ads were running, but the algorithm was learning from map and email clicks instead of real inquiries. Cleaning up the analytics, cutting the noise and feeding the right signals was all it took - and results came in the very first month.

I didn't jump straight into PMax - and that was the right call. First I collected data through Search and identified which segments work and which queries produce real leads. Only then did I launch Performance Max with clean signals - which is exactly why the campaigns delivered immediately instead of "learning" for months.

One closed lead pays for the entire ad spend. The minimum booking at the venue is $4,000+. With a cost per lead of $31–53, even a single closed inquiry per month fully covers the ad budget - and the account generates 50–105 leads per month.

The client is happy with lead quality. Cheap leads that don't convert are worthless. Here the inquiries come from people who actually book the venue - which is why the partnership has continued for over a year.

Minimum client booking. With a cost per lead of about $31, a single closed lead fully covers the monthly ad budget - the remaining 50–100+ leads are pure profit for the business.
