What Is PPC?

PPC is an online ad model where advertisers pay a fee every time their ad is clicked. The most common channels are search (Google/Microsoft), social (Meta, LinkedIn), and retail/marketplaces. PPC is ideal for testing offers quickly, capturing high‑intent demand, and scaling what converts. For brand consistency across ads and landing pages, align with your Marketing Collateral and Marketing Strategy.

How PPC Works (Bidding, Auctions, and Quality)

When a user searches a keyword (or meets audience criteria), an auction runs in milliseconds. Your ad rank depends on your bid and ad quality. High‑quality, relevant ads often pay less per click and win better positions.

• Bid: The max you’re willing to pay for a click.
• Quality/Relevance: Ad & landing page relevance, expected CTR, and user experience.
• Ad Rank: Determines ad position and actual CPC.

PPC vs. SEO: When to Use Each

• PPC = instant visibility, controlled testing, budget‑based scale.
• SEO = compounding, durable visibility with lower long‑term CAC.

Best results come from a mix: use PPC to test messaging/keywords and feed winners back into SEO and content.

How to Set Up a PPC Campaign (Step‑by‑Step)

1. Define the goal: Leads, sales, trials, calls—tie to one conversion action.
2. Research & targeting: Build a seed keyword list and match types (search) or ICP audiences (social). Use insights from Research & Discovery.
3. Structure: Campaign → ad groups/themes → tightly‑matched keywords/ad sets.
4. Create ads: Clear headline, benefit‑led copy, strong CTA. Align the landing page with the same promise.
5. Tracking: Install tags/conversions, verify with test traffic.
6. Budget & bidding: Start with a daily budget aligned to target CPA/ROAS; pick a bidding strategy that matches the goal.
7. Launch & learn: Ship, gather data, and iterate quickly.

Ongoing Optimization Checklist

• Search terms: Add negatives and mine new winners weekly.
• Creative testing: Rotate hooks, benefits, and CTAs every 1–2 weeks.
• Landing pages: Sync headlines with queries; speed, clarity, and proof matter.
• Bids & budgets: Reallocate to high‑efficiency campaigns; cap what’s underperforming.
• Attribution sanity check: Compare platform vs. analytics; watch assisted conversions.
• Compliance & specs: Review the Meta Ads Guide and current Google Ads policies/specs.

Common Mistakes to Avoid

• No negative keywords: Wastes budget on irrelevant queries.
• Too broad account structure: Dilutes relevance; keep tight themes.
• Message mismatch: Ad promise ≠ landing page—kills Quality Score and conversion rate.
• Set‑and‑forget: PPC needs weekly iteration, not quarterly reviews.
