How the project returned after 3 agencies and grew by 40% in turnover

Online store for car audio and accessories
First collaboration: starting from scratch
In June 2023, a project began — an online store for car audio and accessories. At the start, the situation was more complicated than it appeared externally.
After analyzing the account, it became clear:
- e-commerce was not set up at all;
- actual sales data was not being transmitted;
- optimization of advertising campaigns was happening "blindly."
In other words, the system was operating without the main component — without correct data.

What was done:
- a technical task was prepared for setting up e-commerce.
- after implementation — complete testing of events.
- the correctness of transaction transmission was checked.
- product feeds were adjusted.
Two basic campaigns were launched: Performance Max and standard Shopping.

We started to move gradually — adding segmentation by price and highlighting the most successful product groups. The project began to grow, but slowly — which is normal for starting from scratch.

However, by September 2023, the client decided to end the collaboration. Expectations were higher than what the project's development stage allowed.

Period without me: independent management + 3 agencies
After the collaboration was terminated, the client:
Tried to manage advertising independently — for about 3 months, the results began to deteriorate.
Turned to one agency, then to another, and then to a third.
Each of them:
- restructured the account,
- changed the logic of campaigns,
- made adjustments in Merchant Center.
Tea was brewing, the budget was growing, but the improvement in results did not occur, profitability was falling.

June 2025 — return

Almost two years later, the client wrote again.
At the meeting, he honestly said:
- expectations in 2023 were inflated;
- it seemed that the project did not receive enough attention;
- but practice showed that stability is more important than chaotic "restructures."

We agreed on a restart. And this time there was an opportunity to compare —
my working period vs the period of 3 agencies.

Second collaboration: system restoration

At the start, a complete audit was conducted.
First steps:
- campaigns that systematically "sank" results were turned off.
- those campaigns that provided the best economy were kept as the basis.
- the budget was redistributed.
- some campaigns that had started to show promising results back in 2023 were restored.
- the freed budget was directed to effective areas.

Simultaneously, we began launching:
- campaigns for priority categories,
- campaigns for key brands.

Each launch went through testing → analysis → scaling.

Results for the period of the second collaboration compared to the period of agency work:

- Budget increased by 111,000 UAH
Total budget — 577,000 UAH

- Number of sales +10%
Up to 2,730 orders

- Turnover +40%
Up to 3,880,000 UAH
(+1,270,000 UAH growth)

- ROAS increased by 113%
Up to 672%
The project began to scale systematically again, rather than through constant restructures.

Force majeure
In mid-December, a critical situation occurred — Google blocked Merchant Center due to suspicion of misleading.
Unblocking lasted almost until the beginning of February.
A large segment of active sales was lost. But the account was fully restored, and work continues.

Conclusions
- advertising does not tolerate chaotic restructures.
- each "new structure from scratch" pushes the system back.
- data and stability are more important than loud promises of rapid growth.
And most importantly — sometimes the best indicator of work quality is when the client returns two years after three agencies.
