350 USD Comprehensive technical audit of PPC + Analytics: Auto parts niche
Contextual Advertising
Task:
An online auto parts store with a wide range of products.
Client's problem: The budget is increasing, but the number of orders remains stagnant. There are suspicions of ineffective work by the current contractor and technical failures.
Audit goal: Identify budget leakage points, verify data transfer accuracy, and create a scaling plan.
…
What was analyzed and identified:
1. Google Ads Audit
Account structure: Traffic cannibalization was identified. Performance Max campaigns were intercepting branded traffic from search campaigns, artificially inflating ROAS, while actual sales from cold queries were declining.
Semantics: In search campaigns, 30% of the budget was spent on overly broad queries (for example, buying oil without specifying viscosity or brand), which had low conversion rates.
Scripts: Lack of control scripts. Ads led to 450 pages with a 404 error (products out of stock), resulting in direct losses.
2. Google Merchant Center Audit (Feed)
Feed quality: 40% of products had a low-quality rating due to missing mandatory attributes (GTIN/MPN).
Titles: Product names were technical (from 1C), without adding the brand and model of the car (for example, Front brake pads instead of Front brake pads for BMW E60). This significantly narrowed the reach in Shopping.
3. Web Analytics (GA4 + GTM)
Transaction duplication: It was found that 15% of orders were duplicated in analytics due to the reloading of the Thank You Page. This distorted ROAS statistics and misled learning algorithms.
Dynamic remarketing: The data collection code (Data Layer) on the site was incorrectly set up — product IDs did not match the IDs in the Merchant Center feed. As a result, remarketing showed users the wrong products they viewed.
4. Basic website audit (UX/UI)
Mobile version: It was found that the Buy button was overlapped by the online chat on mobile devices, reducing conversion by 0.5%.
Speed: The loading time of the product card was 4.5 seconds due to unoptimized images.
Audit result:
The client was provided with a 5-page PDF document containing facts, screenshots of errors, and a correction plan (Roadmap).
Budget leakage points were identified amounting to approximately 40,000 UAH/month.
Technical errors in analytics were found that inflated actual results by 15%.
A new feed structure was proposed for scaling Shopping campaigns.
After implementing the recommendations, the client expects a profitability increase of 20-30% in the first quarter.

800 USD Notary Services: 6271 applications at 226 UAH each. Local and international
Contextual Advertising
A large-scale project in the field of legal and notarial services.
Geography: Ukraine (Local) + Europe (International targeting of the diaspora).
Project numbers:
… Advertising budget: 1,422,055 UAH.
Number of conversions (applications/calls): 6,271.
Cost per lead (CPA): 226 UAH ($5.6).
Website conversion rate: 4.8% (high indicator for services).
Task:
Ensure maximum office load with local clients and enter the international notarial services market (apostille, powers of attorney, translations).
What has been done:
1. Division of strategies (Local vs International).
For the local market: Launch of Performance Max with a priority on Google Maps. Targeted geotargeting in business districts of the city to attract business clients.
For the international market: Setting up search campaigns targeting Ukrainians abroad (Poland, Germany, Czech Republic, Britain, etc.) who need document legalization.
2. Working with semantics.
Deep clustering of queries. Separate groups for expensive services (real estate registration, inheritance) and flow services (certification of copies). This allowed for flexible bid management and avoiding overpayment for cheap services.
3. Experiments and auto-strategies.
Using A/B tests to transition to the auto-strategy Target CPA (Target Cost per Conversion). This allowed for maintaining a stable application price while scaling the budget.
4. Script automation.
Implementation of scripts for budget control and automatic cleaning of search queries, which is critically important in the highly competitive legal niche.
Result:
A stable flow of clients has been established. With a budget of 1.4 million UAH, over 6,000 targeted inquiries were received at a price significantly lower than the market average. The office has been provided with work for both simple notarial actions and complex international agreements.

1000 USD E-commerce Furniture: Turnover 144 million UAH per year with a DRR of 2.4%
Contextual Advertising
A large-scale project in the Furniture and Home Goods niche.
Task:
To ensure maximum sales volume while maintaining high profitability. Work was carried out over the course of a year with large volumes of data.
… Project figures (Annual report):
Advertising budget: 3,563,479 UAH.
Revenue generated: 144,640,997 UAH.
Gross profit (at a 40% margin): 57,856,398 UAH.
Net profit (after deducting advertising): 54,292,919 UAH.
ROAS (Return on Advertising Spend): 4059%.
DRR (Share of Advertising Expenses): only 2.4%.
What was done:
1. Feed segmentation in Google Merchant Center. Products were divided not only by categories but also by margin. This allowed for aggressive scaling of top positions and prevented budget waste on cheap items.
2. Performance Max + Search. A structure was built where PMax works on reach and remarketing, while Search campaigns capture hot demand for specific product positions.
3. Script optimization. A script was implemented that tracks products with spending but no sales and disables them. This helped maintain DRR at 2.4%.
4. Seasonal scaling. In peak months, the budget was increased by 3-4 times without loss of efficiency due to pre-prepared audiences and bidding strategies.
Result:
A system was built that generates a stable flow of orders with extremely high return on investment (ROAS 4000%+).
