A conversion action is how Google Ads knows what counts as a success on your website. It's a setting in your Google Ads account that names one specific thing you want people to do after clicking your ad, like buying something, filling out a contact form or calling your business.
Each conversion action has its own name, category, value settings and counting rules. When your website reports that the action happened, Google Ads matches it to the ad click that led there and adds it to your campaign results.
Why Conversion Actions Matter
Google Ads can only optimize toward what it can see. If you run Smart Bidding, the conversion actions you set up are what Google is trying to get more of, so they shape where your budget goes.
That makes the choice of conversion action important. A store that only tracks "added to cart" will get bidding tuned for people who add to cart, not for people who buy. A lead gen site that counts every page view of the contact page as a conversion will get bidding tuned for visits, not inquiries.
Each conversion action can also be set as primary or secondary. Primary actions count toward bidding and the Conversions column. Secondary actions are recorded so you can see them, but bidding ignores them. It's a good way to keep an eye on smaller steps (like add to cart) without letting them pull bidding away from the sale.
How a Conversion Action Works
Every website conversion action in Google Ads has two IDs that your site uses to report it:
- The conversion ID, which starts with "AW-" and is the same for every conversion action in your account
- The conversion label, a short code that's different for each conversion action
Google's event snippet shows them together, like AW-123456789/AbC-D_efG-h12. The label is only the part after the slash. When your site reports a conversion, it sends both, so Google knows which account and which conversion action it belongs to.
A conversion action also stores settings like:
- Value: a fixed value, a different value for each conversion (like an order total), or no value
- Count: every conversion (for purchases) or one per click (for leads, so one person filling out a form twice counts once)
- Click-through window: how long after an ad click a conversion can still be credited to it
Conversion Actions on WordPress Sites
On a WordPress site, the hard part is usually connecting each conversion action to the right event on the site, like the right form, the right checkout or the right button. That's normally done by copying the conversion label from Google Ads into a tracking plugin or into Google Tag Manager, one action at a time.
It's easy to get wrong, too: pasting the whole AW-.../label string into a field that only wants the label, or pasting the label for the wrong action, breaks tracking without any error message.
How Conversion Bridge Helps
Conversion Bridge lets you choose which plugin events count as conversions in Google Ads, from form submissions and purchases to bookings and signups across 77 WordPress plugins. Each event gets its own conversion label field.
When your site is connected to Google Ads, every Conversion Label field gets a Choose from Google Ads link. You can pick one of your existing conversion actions, or create a new one right from WordPress, and the label fills itself in. See the Google Ads setup guide for the details, or Google Ads server-side tracking on WordPress for how conversion actions work when conversions are also sent from your server.
Frequently Asked Questions
What's the difference between a conversion and a conversion action? A conversion action is the setting in Google Ads that describes what to count. A conversion is one time it actually happened. One conversion action, like "Purchase," can record thousands of conversions.
How many conversion actions should I have? As many as you have meaningful goals, and no more. Most sites need a few: the main sale or lead, plus maybe a phone call or a secondary step. Too many primary actions makes it hard for bidding to know what you really want.
Where do I find my conversion label?
In Google Ads, go to Goals → Conversions → Summary, open the conversion action, and look at the tag setup. The label is the part after the slash in the send_to value.
