All performance data cited aligns with July 2025 sources. To choose a PPC agency tailored to your specific business need, apply the following criteria:

1. Business Model Alignment

• B2B vs B2C: Ensure the agency has demonstrable results in your market model. B2B requires longer funnels, ABM, CRM integration. B2C prioritises ROAS and rapid conversion.
• SaaS vs Service vs Ecommerce: SaaS needs LTV/CAC analysis; service-based needs lead quality; ecommerce needs feed optimisation and Shopping Ads.

2. Channel & Platform Specialisation

• If your traffic is primarily Google Search, focus on Google Ads-certified partners.
• For LinkedIn-focused B2B campaigns, choose an agency with demonstrated LinkedIn Ads expertise.
• For visual or product-based campaigns, ensure strength in Meta, Shopping, or Display networks.

3. Budget Suitability

• Define monthly media spend and management fees you’re willing to allocate.
• Reject agencies whose fee structures don’t scale with your growth stage (e.g., % of ad spend models may penalise scale).

4. AI & Automation Capability

• For scaling or multi-location campaigns, prioritise agencies with automation (e.g., bid adjustments, script-based optimisation, data layering).
• Check for proprietary tools or integration with external platforms (e.g., Google Ads Scripts, API-driven reporting, CRM sync).

5. Reporting Transparency

• Require weekly/monthly reporting cadence with actionable insights, not just dashboards.
• Ensure KPIs align to your goals: CPL, CAC, LTV, SQL %, ROAS—not vanity metrics.

6. Industry or Vertical Experience

• Prioritise agencies with case studies in your vertical.
• Review account complexity: regulatory, high-ticket, long-funnel, seasonal—verify they’ve handled equivalents.

7. Testing & Experimentation Framework

• Confirm they operate test cycles (A/B ad testing, landing page variants, CTA analysis).
• Look for a culture of iterative improvement, not static campaign management.

8. Conversion & Funnel Understanding

• Avoid agencies focused solely on traffic. They must understand and optimise the post-click experience: landing page UX, form fill rates, CRM handoff.
• Validate whether they support CRO or partner with CRO specialists.

9. Team Structure & Access

• Clarify whether you get a dedicated manager, and whether they’re technical or just a coordinator.
• Identify if senior strategists will touch your account or only oversee.

10. Proof

• Demand benchmarked case studies, not anecdotal claims.
• Check their Google Partner status, client reviews (Clutch, DesignRush, G2), and actual results in platforms.

Final Fit Test: Can they articulate your product, market, ICP, and value prop in 30 seconds? If not, don’t proceed. Additional considerations beyond the core evaluation criteria:

11. Data Ownership and Portability

• Ensure you retain ownership of ad accounts, data, and creatives. Reject agencies that operate under their own MCC or restrict access.

12. Onboarding Process

• Evaluate onboarding depth: do they perform market, competitor, and keyword research pre-campaign?
• Quality onboarding is predictive of long-term strategy coherence.

13. Lead Quality Feedback Loop

• For lead gen: check if the agency integrates client CRM feedback into campaign optimisation (e.g., scoring leads, refining targeting).
• No feedback loop = stagnant lead quality.

14. Regulatory and Sector Compliance

• For finance, healthcare, education, or legal: confirm agency understands advertising restrictions, policy limitations, and approval pipelines.

15. Geographic Targeting Capability

• Multi-region targeting demands knowledge of regional CPC differences, localisation, and time zone-aware ad scheduling.
• Verify with past international campaign experience if relevant.

16. Attribution Modelling Expertise

• Can the agency work with non-linear attribution models (e.g., data-driven, time-decay, offline conversion tracking)?
• Weak attribution = poor budget allocation decisions.

17. Integration with Analytics Stack

• Confirm if the agency works with your tech stack: GA4, Tag Manager, CRM, HubSpot, Salesforce, Looker, etc.
• Disjointed reporting causes blind spots.

18. Contract Flexibility

• Avoid rigid long-term retainers without break clauses or performance reviews.
• 30–90 day notice periods are standard; shorter is better for early-stage firms.

19. Creative & Copy Production

• Do they produce ad creatives in-house? Static, video, responsive search?
• If not, confirm how they handle content iteration or what’s expected from your team.

20. Post-Campaign Learnings & Strategy Reviews

• Ensure structured QBRs (quarterly business reviews) are baked in.
• Demand continuous strategy evolution—not rinse/repeat execution.

Agencies that score well on all 20 are rare. Prioritise according to business stage, vertical, internal capabilities, and growth targets.
