General domain of usage  
Digital marketing campaign optimization

Even the best-planned campaigns can hit bumps. Costs rise, conversions fall, and stakeholders start asking questions.

- Always **diagnose before reacting**: check that tracking is still working, nothing has changed in your setup, and look for macro factors like seasonality or competitor moves;
- A **drop in CTR** usually points to creative fatigue, poor ad relevance, or irrelevant search terms;
- **Rising CPCs** can come from more competition, a bidding strategy change, or declining Quality Scores;
- **Falling conversion rates** often signal landing page issues: slow load speed, poor mobile UX, or misaligned messaging;
- **Low ROAS** may be caused by wasted spend on low-value conversions or a misconfigured product feed in eCommerce;
- Prioritize fixes by impact: Tackle **fast wins** (like pausing underperforming ads) while planning **long-term improvements** (like redesigning UX);
- Communicate findings clearly and test **one** change at a time to avoid guesswork.
