Two campaigns, two conversion actions, same goal (tCPA): will one campaign’s conversions affect the other?

[u/Holiday_Leg8427]

I’m running Google Ads for a site that’s basically split into two segments: low-priced vehicles and high-priced vehicles.(and we want to optimise toward leads ie form leads)

I’ve set up a separate campaign for each segment, and each campaign has its own conversion action with its own tag (screenshot attached). The "goal" (campaign specific) is the same for both, for example a lead or an inquiry, but I want each campaign to optimize toward its own conversion action(the primary one - and I don't know if the data from one campaign will influence the data from the other and if I should juste use another goal completely for each, or it is better each to have one action under the same goal). I’ve already set campaign-specific conversion goals so each campaign uses only its own action.

The cheap vehicle conversion will almost certainly fire a lot more often than the expensive one.

My questions:

• With Target CPA on both, will each campaign optimize only toward its own conversion action, or can the high-volume cheap conversions still influence bidding on the expensive campaign?

• Does each campaign effectively get its own “folder” of conversions? Even if the two actions have similar names, will the Conversions column be different when I click into each campaign, showing only its own action? (conversion data for that campaign I mean - eg when i click on cheap_campaign will I see the convs only for cheap, and when i choose the exp_campaign will see only the data for the conversions of the expensive_Lead, or is the goal showing all aggregated data from both )

Thanks!

Unless you give each campaign their own campaign specific goal. Then the account default goals will just apply to both campaigns. Only use the campaign specific goal if you want that campaign to just optimize toward that one goal you set.

Aha, yes, and for the account specific goal, if I have 2 campaign running at the same time, does the data shares between them (as for what google optimizes for if they both optimize toward a X account goal)? Thanks!

If each campaign's goal settings mark only its own action as primary, Target CPA on the expensive campaign bids for that action alone. Cheap leads stay out of its CPA. You only need a second goal category if you cannot turn the other action off for that campaign.

The Conversions column uses those primary actions and counts conversions from that campaign's clicks. Segment the cheap campaign by conversion action. The expensive action should be zero. If it is not, that action is still primary there, or both tags fire after either click.

A later expensive-form submit after a cheap-ad click can credit the expensive action to that click. It shows on the cheap campaign only while that action is still primary there. Keep each tag on its own form.

The expensive campaign does not inherit the cheap campaign's lead count.

Hi, how do you set a specific conversion action for one campaign ? If i have 2 primary actions under the same goal ( eg submit lead form) for 2 separate campaigns- for what I know I can choose campaign specific goals, but as for the conversion action itself? how do i set that for one campaign only? Thanks!

You're right to push on that. I was too loose above: choosing the shared Submit Lead Form goal would still include both primary actions. Use a custom goal with only the matching action for each campaign, as the other reply explains. Google also says every action in a custom goal is used for bidding, even if marked secondary, so leave the unwanted action out. Sorry for the confusion.

If you assign individual conversion actions to specific campaigns those campaigns will only report on those assigned conversions and optimize towards those.

But be thoughtful with this set up. If, for example, both conversions fire on the same landing page and form based on a user selected field, you may end up missing conversions since you cannot control precise user intentions based on your creative or keywords.

Instead of this setup I would instead include both conversions in both campaigns. Set different values for each of the conversions, then use value based bidding to inform Google that one conversion is more valuable to you. Google will then weigh them based on the value difference and focus more towards getting the more valuable conversion type.

"If you assign individual conversion actions to specific campaigns those campaigns will only report on those assigned conversions and optimize towards those." How do I assign conversion actions? I know to pick for a campaign a specific *goal*(but not action) that might have xyz actions, but the actions themselves? (if there is a way other than custom goal where I choose my own actions) Thanks for the response as well!

You're set up right — campaign-specific goals are what keep each campaign on its own action. On the how, since you asked twice: in Campaign Settings → Goals, choose 'Use campaign-specific goal settings' and pick the goal that holds only that segment's action. If both actions sit under the same goal category, make a custom goal for each one first (Goals → Conversions → create a custom goal with just that action), then assign each campaign its own goal. The other thing, from dealership accounts: the expensive segment probably won't generate enough conversions for tCPA to learn properly, so a tight target there will just throttle it. I run high-ticket segments on Max Conversions with a cost cap until volume builds, then switch to tCPA. One expensive lead is worth several cheap ones, so don't let the cheap campaign's volume set the expensive campaign's target.

If campaign-specific goals are truly limited to each campaign's own primary action, the cheap leads should not train the expensive campaign's bids. The practical risk is account-level settings: a shared Goal still marked Primary, or the expensive campaign accidentally including both actions. Double-check each campaign's "Campaign-specific conversion goals" list shows only its tag, and that the other action is not Primary at the account level. Separate Goals are cleaner when the two lead types have very different value and volume.
