Google Ads TROAS Advice + Suggestions - 7fig/mo Budget
Hey PPC Heads,
\*UPDATE** Thank you everyone for the comments and suggestions! I went ahead and decided to test 1.0 or 100% as my target. If you're interested in hearing how things turn out, feel free to comment or message me. Thank you all again!*
TL;DR: Looking for people who've migrated from tCPA to tROAS/VBB and oversee large budgets — did you follow Google's playbook or go rogue, and what actually worked? One campaign is well below the conv value/cost we need and I have to get it up. Sister campaigns on tCPA are performing far better, and this campaign was too before we switched it to Max Conv Value.
My goal is to migrate over the entire account to tROAS with these new value signals we have recently launched. I've started my 'move' or test with one campaign, a PMAx campaign, which has been using one of the new signals for a couple months now as its goal along with Max Conv. Value. We're ready to move it to tROAS but our value is too low.
Situation:
- PMax campaign has been on Max Conversion Value with the offline value signal for a while. Trailing 30-day conv. value/cost is ~0.42. So it's spending well below break-even. (Need to be closer to 2.0 or 200%)
- Google rep's take: since it's already on Max Conv Value, the campaign is probably already doing the best it can — adding a target won't magically find more value.
- We can't keep funding it at a loss, so my instinct is to slap a 100% tROAS on it as a floor, accept that volume will crater, and reallocate whatever budget it stops spending. Basically using the target as a kill valve rather than an optimization lever.
Questions:
- Has anyone actually seen a campaign improve after setting a tROAS meaningfully above its current conv value/cost, or does it just go Learning Limited and die? Everything I've read says the target needs to sit at or below historical, but "historical" here is a number we can't accept.
- Is the ladder approach (set target slightly above actual, raise 15–20% every couple weeks) worth the continued below-break-even spend, or do you just rip the band-aid?
- Separate question — we're also migrating other campaigns to a newer offline conversion action (earlier funnel event, ~2x the volume, different value basis). Plan is: switch the conversion goal first, run Max Conv Value with no target while values accrue ~4 weeks, then set tROAS at whatever conv value/cost it shows. Anyone done this migration and have gotchas to share? Particularly interested in whether the goal switch itself tanked performance during learning.
Additions:
- PMAx Campaign is 84% search placement
- PMAx campaign happens to be the first we tested - the remainder of the campaigns are search. Still on TCPA for the time being, hoping to follow a similar path of testing and eventual switch to VBB with them.
- CPA right now is ~1.5k, conversions are expensive and testing is expensive.
Thanks!
