Paid Search (PPC)

Paid Search on the OMCP exam tests account structure, keyword intent, bidding, Quality Score, ad copy, landing-page fit, and conversion measurement. Expect questions on match types, negative keywords, search terms, automated bidding, Shopping and Performance Max, and diagnosing cost per acquisition.

Core rules and concepts

  • Match intent: exact, phrase, and broad match have different reach and control. Mine the search terms report and add negatives continuously.
  • Quality Score reflects expected click-through rate, ad relevance, and landing page experience. Ad Rank is commonly modeled as bid times Quality Score plus expected impact of ad formats and assets.
  • Separate branded and nonbranded campaigns so budgets and CPA targets are not blended misleadingly.
  • Choose bidding by goal: manual or portfolio bidding for control, target CPA or target ROAS where conversion data is adequate.
  • Match ads and landing pages to query intent; use responsive search ads and extensions/assets, pinning sparingly.
  • Track primary conversions, attribution, new-customer acquisition, and margin-not clicks alone.

Worked example

A campaign has an $80 CPA against a $50 target. The search terms report shows 30% of spend on job and salary queries. The team adds negatives, splits branded from nonbranded, shifts budget to exact high-intent terms, and improves landing-page speed. Reasoning: the waste is query-level, so raising bids would worsen CPA. Fix relevance and tracking first, then test bid strategy with enough conversion volume.

Traps that cost marks

Broad match without negatives, optimizing CTR instead of CPA, blending branded and nonbranded, ignoring search terms, landing-page mismatch, and bidding to top position without margin.

Key points

  • Search terms drive negative keyword decisions.
  • Quality Score has three components: expected CTR, ad relevance, landing page experience.
  • Separate branded and nonbranded budgets.
  • Use tCPA or tROAS only with adequate conversion data.
  • Match ads and landing pages to query intent.
