Google Ads
Google Ads don't just go live. They learn. Here's what that looks like.
The most expensive mistake in month one isn't a bad headline. It's changing things before Google has had time to learn what works.

The most common mistake in the first 90 days of a Google Ads campaign is also the most damaging: making changes too quickly. Google's algorithm needs time to learn your account. Every time you intervene before it has enough data, you reset that learning cycle. What feels like optimising is often creating a new problem. The clinic that understands this dynamic will get significantly better results from the same budget than the one that doesn't.

Month 3
Quality score takes 4 to 6 weeks to stabilise.
Google assigns a quality score to every keyword in your campaign. It's a rating from 1 to 10 that reflects how relevant your ad and landing page are to someone's search. It directly affects how often your ad shows, which position it appears in, and how much you pay per click. A high quality score means Google rewards you with better placement at lower cost. A low one means you pay more for worse results.
That score takes 4 to 6 weeks of real data to build. Until it stabilises, your costs will be higher and your reach narrower than they'll eventually be. That's not a sign the campaign is failing. It's the algorithm learning what your account is about.
Most clinics who manage their own ads don't know this. They see costs that look high in week two and start changing headlines, switching keywords, or reducing budget. Every major change resets the quality score build. The campaign never gets past the learning phase. Month after month, they stay stuck at the expensive early-stage performance that should only last 6 weeks.
We make changes every 14 days minimum. Test it, leave it, measure it, then make the next decision from data. That's the whole methodology.
The four phases of a Google Ads account.
Here's exactly what should be happening in each phase, and what the biggest mistake is in each one.
How a well-managed account actually progresses
Weeks 1 to 2
Strategy and launch
Ideal client research, keyword selection, negative keyword loading, budget reverse engineering, headline and description writing, landing page review. Every part of the campaign is built before a single dollar is spent. The setup determines the ceiling. Rushing this phase to get ads live faster costs more in the long run.
Weeks 3 to 6
The learning window
This is where most DIY campaigns go wrong. Google is collecting data, quality score is building, and the algorithm is learning which searches and users convert. The correct action is to review search term reports, add negative keywords for irrelevant searches, and resist changing headlines or pausing campaigns. The urge to intervene is strong. Resist it.
Month 2
First optimisation round
Now there's real data to work with. Split test headline variations and compare performance. Adjust keyword bids based on which searches are actually converting. Remove search terms that are spending without producing bookings. Every decision is made from data, not instinct. Still no major structural changes.
Month 3 and beyond
Scale what's working
Once you know which campaigns, keywords, and headlines are producing bookings at an efficient cost, scale them. Increase budget on the highest performers. Build out new ad groups for presentations that are proving themselves. The efficiency compounds month on month because every optimisation round builds on the last one.
DIY versus professionally managed.
The gap between a DIY account and a well-managed one compounds over time. In month one it might be small. By month six, it's the difference between an account that's getting more efficient every cycle and one that's been stuck in the learning phase since day one.
DIY account
- Changes made whenever performance feels off, often weekly
- One set of headlines running with no split testing
- Negative keywords added one by one when bad search terms appear
- Budget adjusted based on gut feel, not conversion data
- Quality score treated as a mystery number, not a lever
- Account abandoned after 6 to 8 weeks without visible results
Professionally managed account
- Changes made on 14 day cycles, every decision backed by data
- Multiple headline and description variants tested simultaneously
- Negative keyword lists loaded from day one, built across 100+ clinic accounts
- Budget scaled after efficiency is proven, not before
- Quality score actively managed and improved as a priority lever
- Results compound month on month because learning is never reset
