Google Ads = paid search (intent-driven, customer is actively looking). Facebook Ads (Meta Ads) = paid social (interruption-driven, customer wasn't looking but may be interested). Different mechanics, different best uses.
**Google Ads (search) — the intent capture machine:**
**How it works:** users search a query expressing intent ("emergency plumber Toronto"). Your ad appears at the top of search results. You pay per click. The user clicks because they're actively looking for what you sell.
**Best for:** capturing existing demand. High-intent purchases ("buy X now"). Service businesses where customers search at moment of need (trades, legal, medical, insurance, professional services). Lead generation for considered purchases.
**Strengths:** highest-intent traffic available. Predictable conversion economics once tuned. Direct attribution (click → conversion). Works for niche/specific products that paid social can't easily target.
**Weaknesses:** can't generate demand that doesn't already exist (no one searches for products they don't know they need). High CPC in competitive categories ($20-200+/click in legal, financial, medical). Limited audience targeting beyond the keyword.
**Meta Ads (Facebook + Instagram) — the demand generation machine:**
**How it works:** users scroll their feed for entertainment/social. Your ad appears between organic posts. You pay per click or per impression. The user wasn't looking for anything but may be interested in what you're showing.
**Best for:** generating awareness and demand for products people don't actively search for (DTC consumer products, lifestyle brands, ecommerce, anything visual). B2C with broad audience appeal. Retargeting people who've engaged with you elsewhere.
**Strengths:** unmatched targeting precision (interests, behaviors, lookalikes from your customer list). Lower CPC than Google in most categories. Strong creative formats (video, carousel, stories). Great for brand-building alongside performance.
**Weaknesses:** lower-intent traffic (people scrolling, not searching). Requires strong creative — bad creative simply doesn't work. iOS 14+ limited tracking has degraded attribution. Performance Max-style campaigns less mature than Google's.
**The mental model:**
**Google Ads asks:** "Who is searching for what I sell right now?" Then it captures them.
**Meta Ads asks:** "Who looks like the kind of person who'd want what I sell?" Then it interrupts them.
**Both used together (the most common winning approach for product/service businesses):**
- **Google Ads** captures bottom-of-funnel, high-intent searches - **Meta Ads** generates top-of-funnel awareness and retargets people who showed interest but didn't convert - Together they cover both "I'm searching for this now" and "I'd want this if I knew it existed"
**Budget allocation guidance:**
**Pure ecommerce / DTC:** typically 60-80% Meta, 20-40% Google
**Local services:** typically 70-90% Google, 10-30% Meta (for awareness)
**B2B SaaS/services:** typically 40-60% Google, 20-40% LinkedIn, 10-30% Meta
**Lead gen for high-ticket services:** 60-80% Google, 20-40% Meta (retargeting + lookalikes)
**The diagnostic for which to start with:**
Google Ads search volume report: type your category keywords into Google Keyword Planner. If there's significant search volume (1,000+ monthly searches in your area for relevant queries), Google Ads is in play.
If there's low search volume but the audience exists (e.g., a new product category, a lifestyle brand), Meta is your starting point — you have to interrupt people who don't know they want this yet.
**Other PPC platforms worth knowing in 2026:**
**Microsoft Ads (Bing):** ~10% of US search market, often 30-50% lower CPC than Google for the same keywords. Worth running parallel to Google Ads if you have time. Demographics skew older + higher income.
**LinkedIn Ads:** premium B2B targeting. CPC $5-25+ but high deal sizes can justify. Best for enterprise SaaS, consulting, executive recruiting, premium services.
**TikTok Ads:** strong for visual consumer products. Younger demographic. Growing fast.
**YouTube Ads:** managed within Google Ads. Strong for video-friendly products and high-consideration purchases where demonstration matters.
**Pinterest Ads:** specific verticals (home, wedding, food, fashion, design) where Pinterest's high-intent female audience converts.
**Amazon Ads:** if you sell on Amazon. Different mechanics from external paid search; often the highest-ROAS channel for Amazon-listed products.
- **How much should I spend on Google Ads to start?** — Minimum useful test budget is $1,500-3,000 over 60-90 days. Below that, you don't generate enough data to optimize. The right ongoing budget depends on cost-per-acquisition economics, not a generic percentage. - **What is Quality Score and how do I improve it?** — Google's 1-10 measure of how relevant your ads, keywords, and landing pages are to a query. Higher score = lower CPC + better positions. Improve via tighter ad groups, ad relevance to keyword, and landing page experience. - **Should I bid on my brand name in Google Ads?** — Usually yes — competitors will bid on your brand if you don't, brand keywords are typically very cheap, and brand campaigns often have the highest ROAS in the account. The "I already rank organically" objection misses the point. - **What is a good CTR for Google Ads?** — Industry average is 3-5% on Search Ads, 0.5-1% on Display. Above 6% on Search is good; above 10% is excellent. Brand campaigns commonly hit 15-30% CTR. Below 2% suggests your ads or targeting need work.
