Technical Evaluation Framework: Procuring SEM & Paid Search Agencies
Investing in Search Engine Marketing (SEM) demands rigorous governance over media spend efficiency, bidding algorithms, search term hygiene, and downstream conversion attribution.
1. Bidding Architecture & Campaign Engineering
- ▸
Algorithmic Smart Bidding Strategy: Expertise in configuring tCPA, tROAS, and value-based bidding alongside first-party conversion data injection (Enhanced Conversions, Offline Conversion Imports).
- ▸
Match Type & Query Governance: Structured intent segmentation, disciplined negative keyword lists, and proactive monitoring of search term match expansion.
- ▸
Creative & Ad Copy Systems: Continuous multivariate responsive search ad (RSA) testing, ad customizers, dynamic asset insertion, and alignment with high-converting landing pages.
2. Buyer Diligence & Vetting Criteria
- ▸
Direct Account Ownership: All ad accounts, payment profiles, and historical data must remain exclusively owned and controlled by your organization.
- ▸
Margin-Aware Bidding Integration: Ability to integrate CRM and ERP data to optimize ad bidding toward gross profit and customer lifetime value rather than vanity platform ROAS.
- ▸
Audited Fee Models: Complete transparency into management fees, avoiding marked-up media spend or opaque third-party programmatic arbitrage.
3. Red Flags to Watch For
- ▸
Media Spend Arbitrage: Agencies taking a percentage markup on media spend without providing direct access to raw Google Ads invoices.
- ▸
Reliance on Automated Recommendations: Mindlessly accepting Google Ads automated apply recommendations (auto-applied ad suggestions, broad match expansions).
- ▸
Neglected Negative Keyword Lists: Zero cadence of weekly negative search term pruning, resulting in high budget leakage on irrelevant search queries.
