Real-world example: selecting an agency for a growing ecommerce brand

Situation: A mid-sized ecommerce company with INR 50M annual revenue needed higher margins from paid channels and consistent organic growth. Requirement: Improve Google Ads ROAS and stabilize organic traffic during seasonal peaks.

Process: The company used the RAPID framework to shortlist three agencies: a performance-first firm, an SEO specialist, and a full-service agency. Each provided a 30-day audit and a 90-day plan. The performance firm improved ROAS within 8 weeks by restructuring campaigns, while the SEO specialist delivered a technical cleanup that reduced crawl errors and improved product indexing. The team selected a hybrid approach—paid campaign overhaul plus an SEO sprint—and set up GA4 and server-side tracking for accurate attribution.

Practical tips for evaluating proposals

• Insist on a sample audit before awarding work—score each audit against the same criteria
• Ask for measurable objectives and SLA-driven timelines, not vague deliverables
• Request transparent fee breakdowns: setup vs monthly retainer vs media spend
• Confirm ownership of ad accounts and data portability clauses in the contract
• Schedule a 60–90 day review milestone to decide whether to scale or pivot

Common mistakes and trade-offs when hiring an agency

Common mistakes

• Choosing the cheapest option without verifying deliverables or past results
• Expecting instant organic traffic gains—SEO requires sustained work
• Not aligning internal resources (content, product, dev) for implementation

Trade-offs to consider

• Speed vs depth: performance agencies may act fast on paid channels; SEO specialists take longer but build long-term organic equity
• Cost vs control: full-service agencies offer convenience, while specialists often provide deeper expertise for specific tasks
• Scalability vs bespoke service: smaller boutiques may provide hands-on work but struggle to scale large campaigns

Next steps: running an effective agency pilot

Define a 60–90 day pilot with clear deliverables (audit, 30/60-day roadmap, tracking implemented). Use the RAPID framework to score outcomes and hold a formal review at the pilot end. If metrics improve and handoff processes are clear, scale work gradually while keeping monthly review checkpoints.
