Smart bidding
Smart bidding is automated bidding that sets each bid using signals about the user and context at auction time, optimising toward a conversion or value target.
What is smart bidding?
Smart bidding is automated bidding that sets each bid using signals about the user and context at auction time, optimising toward a conversion or value target. It requires conversion data to learn from.
Why anybody cares
It outperforms manual bidding where there is enough conversion volume, and underperforms it where there is not.
What the work looks like
Needs roughly thirty conversions in thirty days per campaign for a cost-per-acquisition target, and more for a value target because value adds variance. Each material target change restarts the learning period.
What it is not
It cannot compensate for bad conversion data. If the tracking counts the wrong things, smart bidding optimises efficiently toward the wrong things.
It is a small idea with a disproportionate effect on how a site performs.
Where this comes up in the work
It is part of Paid Social and Meta Ads, and more specifically of Meta Ads management. Across the rest of the work it shows up in:
- Answer Engine Optimization, where it quietly limits how far making the comparison answers specific enough to be useful to someone deciding can go
- Technical SEO, where it sets the ceiling on sorting which 404s deserve a redirect and which deserve to stay gone
- Entity and Semantic SEO, because settling on one name for the thing and using it everywhere depends on it
- Local SEO, in which it shows up as fixing the aggregator record so the corrections stop reverting
What to check
Two questions that establish whether this is actually in order on a given site:
- Whether a new page inherits it automatically or has to be remembered
- Whether the staging behaviour matches production behaviour
Common questions
How do you check smart bidding on a site?
Needs roughly thirty conversions in thirty days per campaign for a cost-per-acquisition target, and more for a value target because value adds variance. Each material target change restarts the learning period. Anybody with access can establish it in an afternoon.
Whose job is smart bidding?
Usually whoever owns Google Ads Management, because working out whether the lead quality problem is the form or the targeting depends on it. In practice it falls between teams often enough that naming an owner is half the fix.
Is smart bidding expensive to get right?
It depends entirely on where the problem originates. Establishing that is the first piece of work.
How urgent is smart bidding?
Before anything that depends on it, which is the test rather than a general ranking. It outperforms manual bidding where there is enough conversion volume, and underperforms it where there is not. Read Nonprofit and NGO next if the problem is already defined, and Real estate and property if it is not.
How would we know smart bidding is a problem?
It outperforms manual bidding where there is enough conversion volume, and underperforms it where there is not. The evidence is specific to the site, which is why the check comes before the recommendation. Entity and Semantic SEO covers the setup, Generative Engine Optimization the maintenance nobody budgets for.
What is smart bidding often confused with?
It cannot compensate for bad conversion data. If the tracking counts the wrong things, smart bidding optimises efficiently toward the wrong things. Pair this with In-house team or Agency, and with Last-click attribution or Data-driven attribution if the market is competitive.
