The article is the full, canonical source. **Direct answer:** The article states that many advertisers capture only 50% to 70% of real performance due to cookie restrictions, privacy regulations, ad blockers used by roughly 30% of internet users, and conversion paths spanning 2 to 3 devices. It recommends a complete 2026 stack of GA4 linked to Google Ads with data-driven attribution, enhanced conversions, Advanced Consent Mode V2, and server-side tagging where needed. The article positions accurate tracking as the foundation because Smart Bidding strategies like Maximize Conversions and Target ROAS can only optimize toward conversions they can see. ## How do I import GA4 conversions into Google Ads without double-counting? According to groas, the link is created in GA4 under Admin, then Product Links, then Google Ads Links, with auto-tagging enabled in Google Ads under Settings, then Account Settings. Conversions are then imported in Google Ads under Tools and Settings, then Conversions, then Import from Google Analytics 4 properties. The article warns not to track the same conversion in both systems simultaneously, and states that if using GA4 events, the Google Ads native tag for the same action must be removed or set to Secondary (not Primary).

The article states that enhanced conversions capture first-party data such as email address, phone number, or mailing address, hash it using the SHA-256 algorithm, and send the hashed data to Google to match against logged-in user data. This connects the conversion to the ad click even when cookies have been deleted, the user switched devices, or browsing has aggressive cookie restrictions. Advertisers implementing enhanced conversions typically see a 5% to 15% increase in reported conversions because previously invisible conversions are now measured.

According to groas, verification uses Preview mode to submit a test conversion and confirm user-provided data variables are populated, then Google Ads under Tools and Settings, then Conversions, then Diagnostics should show Enhanced conversions: Active. The article states Google recommends waiting 72 hours after implementation before checking diagnostics. A healthy implementation shows 50% or more of conversions enhanced, while below 30% typically indicates data capture is not working on all conversion paths and needs investigation.

The article recommends Advanced Consent Mode for almost every business. It states Basic Consent Mode blocks all Google tags until consent, and with global cookie acceptance rates averaging around 31%, Basic means losing data on roughly 69% of traffic with no signals to model. Advanced Consent Mode loads tags in cookieless mode sending anonymous pings without cookies when users reject, which provides enough aggregate data for conversion modeling.

According to groas, server-side tagging requires a server to process data via the Cloud Run option on Google Cloud Platform. For a medium-traffic website (100,000 to 500,000 monthly sessions), the article states to expect to pay roughly $50 to $150 per month for server costs. Managed server-side tagging solutions that simplify setup start at approximately $20 per month for lower-traffic sites.
