Google Ads conversion actions: what counts as a result, and how Smart Bidding uses it

A conversion action is a result you track in Google Ads, such as a lead form, phone call or purchase. Each action has settings: Primary (used for bidding and the Conversions column) or Secondary (reported only), count One or Every, a conversion window, and a value. Smart Bidding optimises toward Primary actions, so only real business results should be Primary.

Bidding for page views

A Thiruvananthapuram clinic’s Google Ads showed 400 conversions a month and a cost per conversion of ₹60. The clinic got about 40 patient enquiries.

A “page view” action imported from GA4 was set to Primary next to the real form submit. Smart Bidding was chasing cheap page views.

We set page views to Secondary and kept form submits and calls as Primary. Reported conversions fell to 45, cost per conversion rose to ₹520, and real enquiries increased the following month.

Illustrative example based on a common pattern in Kerala e-commerce accounts. Numbers rounded.

What a conversion action is

You create conversion actions in Goals → Conversions, by tag, Google Analytics import, calls, or offline imports from a CRM. Each belongs to a goal category like Submit lead form or Purchase.

Primary actions appear in the Conversions column and train Smart Bidding. Secondary actions appear in All conversions for reference only.

Primary = bidding + Conversions column · Secondary = reporting only

How experienced marketers use Conversion action (Primary / Secondary)

  1. 1. Clean bidding signals

    One clear Primary action per goal stops Smart Bidding chasing the wrong thing.

  2. 2. Track micro-actions safely

    Keep WhatsApp clicks or brochure downloads as Secondary for insight without skewing bidding.

  3. 3. Bid for quality

    Import CRM-qualified leads as Primary once volume allows.

When the number lies

Double counting
A tag and a GA4 import for the same lead, both Primary, double the conversions.
Micro-conversions inflating results
Clicks and page views as Primary make cost per conversion look cheap.

Mistakes to avoid

  • Every action set to Primary

    Smart Bidding optimises for easy actions, not customers.

  • Count Every for lead forms

    One person submitting twice counts twice.

  • Ignoring status warnings

    Bidding runs on missing data for weeks.

Questions people ask about a conversion action

What is a conversion action in Google Ads?

A result you track, such as a form submit, call or purchase, with settings that control how it’s counted and used.

What is the difference between Primary and Secondary conversions?

Primary actions are used for bidding and the Conversions column; Secondary are reported in All conversions only.

Should lead forms count One or Every?

One, so repeated submissions from the same click count once.

Why does my conversion action say Needs attention?

Usually the tag stopped sending data, a CRM import has no recent matches, or settings need review. Check the diagnostics.
