2026年のペイドサーチ戦略 — 何が変わったか、そして何をすべきか

Google Ads has undergone more structural change in the past three years than in the preceding decade. The transition from keyword-first to intent-first matching (broad match evolution), the default shift to smart bidding strategies (Target CPA, Target ROAS), the introduction and iteration of Performance Max, and the progressive deprecation of manual CPC bidding have together changed what good Google Ads management looks like. The playbook that produced 4× ROAS in 2022 — tight exact match keyword lists, manual CPC, heavily segmented ad groups — is largely counterproductive in 2026, because it fights the machine's ability to find conversion-ready audiences instead of feeding it. The 2026 paid search strategy that generates profitable ROAS works with Google's automation, providing it with the clean inputs (conversion data, audience signals, creative assets) it needs to optimise effectively.

Conversion tracking — the foundation everything else depends on

If conversion tracking is misconfigured, every smart bidding decision Google makes will be wrong — because the machine is optimising for the wrong signal. The most common conversion tracking errors we find in Google Ads audits: counting page views instead of actual conversions (the confirmation page view being tracked as a conversion rather than the form submission or purchase event); double-counting conversions (both GA4 imported conversions and Google Ads native tracking firing for the same action); including micro-conversions (page views, scroll depth) in the primary conversion column instead of separating them into secondary conversion actions; and counting returns and refunds as positive conversions without any reconciliation. Fix the conversion tracking first. Then set the smart bidding strategy. Smart bidding with clean tracking produces better outcomes than manual CPC in almost every mature account — but smart bidding with broken tracking produces systematically bad outcomes that compound over time.

Performance Max — how to feed the machine correctly

Performance Max campaigns automate placement across all Google channels (Search, Shopping, Display, YouTube, Gmail, Maps) from a single campaign. The quality of outputs is almost entirely determined by the quality of inputs: audience signals (customer match lists, remarketing audiences, similar audiences), creative assets (headlines, descriptions, images, videos — the more variations the better, especially video), and conversion goals (primary conversions must be your highest-value actions). The management approach for Performance Max is fundamentally different from search campaign management: there is no keyword-level visibility, no placement-level bidding, and limited transparency into where impressions are being served. The levers available are asset quality testing, audience signal refinement, and conversion goal clarity. Brands that succeed with Performance Max invest heavily in creative asset quality — particularly video — and update asset groups quarterly to prevent performance decay from creative fatigue.

Next step

Three actions this week. One: audit your conversion tracking — verify that your primary conversions are actual revenue-generating actions (purchases, qualified form fills), not micro-conversions. Two: check conversion volume per campaign — if any campaign has fewer than 30 conversions per month, switch to Maximise Conversions (no target) and consolidate into fewer campaigns. Three: review your Performance Max asset groups — are there video assets? If not, add at least one video per asset group, even a simple 30-second branded video.
