Counting a download as a conversion steers your bidding at nothing
Automated bidding optimizes toward the actions you have marked as primary. The downloaded document, spec sheet or guide, happens fifty times more often than a quote request. Marked primary, it crushes the other and becomes the real target of your budget.
The setting is almost always inherited. Someone ticked every available action at installation, out of caution, so as not to lose anything. Nobody has revisited the list since, and it now holds downloads, chat openings, clicks on an email address and sometimes time spent on a page.
The system then does exactly its job. It looks for the people most likely to download a document, which is not the same population as the one asking for a price. Your cost per conversion improves, your real enquiries stall, and the monthly report shows progress.
This is the most common case of a campaign that performs on paper and produces no revenue, and it is not fixed by changing the creative or raising the budget.
The check takes a minute and almost always starts a conversation. Line up the list of actions marked primary against the list of what your sales team considers a real opportunity. The two lists rarely match.
The hierarchy that works
One primary action per business objective, the one that starts a commercial conversation. Depending on your model, that is the quote request, the booked meeting or the phone call. Everything else, downloads included, stays measured but marked secondary, which keeps it visible in your reports without influencing bidding.
The same rule applies to values. Attaching a monetary value to a download tells the system how much you accept paying to get one, and it will take you at your word.
If your enquiry volume is too low to feed the learning, the answer is not to promote downloads to primary. It is to keep an intermediate action that genuinely correlates with sales, chosen by looking at your won deals rather than by guessing.
The two-minute check
- Open your list of conversion actions and note which are marked primary.
- For each one, ask how many closed sales came from it in the past year.
A primary action nobody can tie to a sale is a target you are funding for no reason. It switches to secondary in a minute.
Revisiting that hierarchy and tying it to your won deals is part of what we cover in a paid audit.
Changing the list of primary actions restarts a learning period. Do it at the start of a cycle, never on the eve of a commercial peak.
