Ad platform comparison

Choosing between Meta, Google, TikTok, and LinkedIn in 2026

Every quarter I get the same question from founders: "Should we be on TikTok?" or "Should we add LinkedIn?" The honest answer is never a single platform recommendation — it depends on ACV, ICP behavior, creative capacity, and measurement maturity. This comparison tool translates those inputs into a ranked recommendation with specific cost and return expectations. What it cannot do is decide for you; it narrows the field from "any platform" to "these two are worth piloting."

The underlying dataset combines 2025–Q1 2026 CPM and CPC benchmarks from 180+ B2B SaaS and DTC ecommerce accounts with published platform cost data (Meta Ads Q4 2025 revenue call, Google Ads 2025 annual report, TikTok Business internal benchmarks shared at partner summit Jan 2026, LinkedIn Marketing Solutions Q1 2026 pricing update). Benchmarks listed are medians; the 10th and 90th percentile spreads are wide (often 2.5x), so treat these as starting points.

Cost benchmarks by platform (Q1 2026)

The audience fit question: where your buyers actually spend time

Platform cost is secondary to audience fit. A $48 CPM on LinkedIn reaching 200 exact-match VPs of Engineering at your target accounts beats a $9 CPM on TikTok reaching 50,000 random consumers. For each platform, the fit question to ask honestly: (1) Meta — do your buyers scroll Instagram/Facebook during the day? (2) Google — do they search explicitly for your category with commercial intent? (3) TikTok — are they under 35 and consumer-category decision makers? (4) LinkedIn — are they making B2B buying decisions during work hours? If the honest answer to a platform's question is "probably not," skip the platform entirely.

Creative format requirements that determine cost-per-acquisition

Each platform rewards different creative. Meta still rewards polished direct-response ads (clear product shot + proof point + CTA) but algorithm increasingly favors video over static (Reels get 1.8x the reach of static at equivalent spend in Q1 2026). Google Search ads are text-forward — the landing page experience determines CPA more than the ad copy. TikTok rewards native-feeling, UGC-style content; polished studio creative consistently underperforms by 30–50% on TikTok vs native-style. LinkedIn rewards opinion-led, founder-voice content over polished brand creative — the "feels like a human posted this" test matters more on LinkedIn than any other platform.

The attribution reality: which platform you can trust the data from

Post-ATT (iOS 14.5+) and post-GA4 transition, attribution trustworthiness varies. Meta's in-platform attribution overstates true contribution by 25–45% for most DTC accounts (verified via geo holdouts across 12 brands I ran incrementality tests on in 2025). Google Search attribution overstates by a smaller margin, 10–20%, because most clicks are already high-intent. TikTok's self-reported attribution is the least reliable in this set — overstate ratio of 40–80% is common. LinkedIn is closer to accurate because B2B sales cycles are long and LinkedIn-sourced leads typically show up identifiable in CRM. Treat Meta / TikTok numbers with a 30% haircut; trust Google and LinkedIn within 15% of self-report.

Scenario recommendations by business type

DTC ecommerce, $2M–$20M revenue, under-35 consumer focus: Meta primary (65% spend), Google Shopping + Brand (20%), TikTok (15%). Add LinkedIn only if selling to procurement or B2B channels.

B2B SaaS, under $5k ACV SMB focus: Google Search primary (50%), Meta retargeting + prospecting (35%), LinkedIn (15%). TikTok not advised below $10M ARR — reach-to-lead conversion is too inefficient for SMB SaaS.

B2B SaaS, $10k+ ACV enterprise: LinkedIn primary (55%), Google Search (30%), Meta (15%). TikTok essentially zero unless doing brand-top-of-funnel for a category that justifies it.

High-ticket coaching / services ($3k–$10k price point): Meta primary (55%), YouTube In-Stream (25%), Google Search (15%), LinkedIn (5%). TikTok optional if creator is willing to film native-format content 3x/week.

DTC ecommerce, 35+ audience / household categories: Meta primary (60%), Google Shopping (30%), Pinterest (10%). TikTok not prioritized — the audience is on Meta and Pinterest, not TikTok.

Minimum viable budget per platform

Below certain spend thresholds, platforms don't produce statistically significant signal and shouldn't be tested. Minimums I use when advising founders: Meta $3k/month minimum, $10k/month for real learning. Google Search $2k/month minimum for intent capture, $8k+ for full competitive coverage. TikTok $4k/month minimum (below this, creative refresh cadence can't be maintained). LinkedIn $5k/month minimum (CPCs are too high for smaller budgets to produce meaningful data). Running $1k/month across three platforms is how small teams burn budget — concentrate at least $4–5k on one channel before adding a second.

The expansion sequence: when to add a second or third platform

1. Platform 1 delivers consistent CAC inside target range for 60 consecutive days.
2. Team capacity exists for a second platform's creative cadence + weekly optimization (typically 10–15 hours / week of media buyer time).
3. Budget for platform 2 is at least the platform's minimum-viable threshold — not scraps from platform 1.
4. Measurement framework is in place — MER target, attribution model agreed, reporting cadence weekly.
5. Creative pipeline is already operating with sustainable format (UGC contracts, internal video team, etc.) for platform 2's format requirements.
6. Platform 1 doesn't regress — don't take spend away from a performing channel to fund an experimental one; add incremental budget.
