After that, you can proceed with the following steps: Compare verified client reviews on Clutch for evidence of ROI. Look for niche expertise, e.g., content marketing agency London specialists if storytelling is key. Assess cultural fit during discovery calls—ask to meet the strategist, not just sales. Confirm tools and reporting cadence; real-time dashboards are a plus. Request local references or sample performance reports.

One-size-fits-all proposals with no mention of your audience or competitors. Limited transparency around ad spend allocation. No in-house analytics talent or reluctance to share raw data. High staff turnover; ask whether your account will be handled by junior or senior specialists. If any of these appear during the pitch, keep looking. Don’t be too concerned about taking too long, as it’s always better to be partnered with a highly capable team than a subpar provider.
