Should I import GA4 key events into Google Ads?

It can be convenient, but for performance campaigns a direct Google Ads tag or offline import often gives more control. The important thing is not to measure the same business event twice as primary.

Should phone clicks be primary?

Usually not automatically. A phone click is a weaker signal than an actual call or qualified lead. If you do not measure real calls, use the click carefully and often as secondary instead.

What if I have too few conversions?

Do not add weak microevents as primary just for volume. Instead, simplify the campaign structure, increase budget for one goal, or temporarily use an intermediate step that truly correlates with business value.

Google Ads conversion actions technically: source, category, count, value, primary, and imports without duplicates

Conversion actions in Google Ads are not just a name and tag. Each action has a source, category, primary/secondary status, count, value, conversion window, attribution settings, and import rules.

Short Answer

Conversion actions in Google Ads are not just a name and tag. Each action has a source, category, primary/secondary status, count, value, conversion window, attribution settings, diagnostics, and sometimes import rules and a relationship to account-default or campaign-specific goals. If you configure this incorrectly, Smart Bidding can learn from clicks, duplicates, or historical events with no business value.

A technically sound account has a clear conversion map: what is the business goal, what is an intermediate step, what is only diagnostics, what is imported offline, what is deduplicated, and what will never be used for bidding.

Source: Google Ads Tag, GA4 Import, Offline Import, Or API

A direct Google Ads tag gives the ad system a more direct signal. GA4 import is convenient and often usable, but it can introduce differences in attribution, delay, or event definition. Offline import is essential for lead generation and deals closed outside the website. API or Data Manager makes sense for robust automation.

The biggest mistake is measuring the same business event twice as primary: once with the Google Ads tag and again through a GA4 import. The result can look like performance growth, but it is only signal duplication.

Category And Naming Are Not Cosmetic

Conversion category helps organize goals and reporting. Names must be readable: Lead - form submit, Qualified Lead - offline import, Purchase - web, Booking confirmed - webhook. A name like Conversion 1 is audit hell.

If the event meaning changes, do not hide it under the same name. Form submit and Qualified Lead are not the same thing. Purchase created and Order paid are not the same thing either.

Primary Vs Secondary

Primary conversions are typically included in the Conversions column and used for bidding if the campaign uses them. Secondary conversions are mainly for observation and All conversions. A good account does not make microevents primary just to increase volume.

Primary should correspond as closely as possible to business value: purchase, qualified lead, booking confirmed, deal won. Secondary can include form_start, click_phone, view_contact, add_to_cart, begin_checkout, or newsletter.

Count: Once Or Every

For leads, count once usually makes sense because one user submitting three times is not three times the business value. For purchases, every makes sense because each purchase is a separate business event. For phone calls, it depends on the definition: the first qualified call may be once, while repeated order calls may be every.

Bad count settings distort CPA and bidding. If a thank-you page refresh creates three leads and count is set to every, the account learns from technical duplicates.

Conversion Value

For ecommerce, send the actual purchase value and currency. For lead generation, start with estimated value by lead quality or use offline value when the lead becomes qualified. A rough but consistent value is better than no value in campaigns that are supposed to optimize for value.

Do not send the same value for all forms if you know that an enterprise demo has a completely different value than a general contact. At minimum, distinguish lead_type or import qualified statuses.

Control Checklist

Check conversion name, category, source, primary/secondary, count, value, attribution settings, conversion window, deduplication, consent, tag diagnostics, GA4 import, offline import, account-default goals, and campaign-specific goals. Then test a real event from click through the website all the way to visibility in Google Ads diagnostics.

Do not forget change control. When you change the primary conversion in a running campaign, you change the learning signal. Performance may become unstable in the short term, but that does not mean the fix was wrong. It means the algorithm is learning from different data.
