Paid search can work well for manufacturers, but the default measurement settings are built for businesses that close in days. When a deal takes months, the reporting tells you the campaign failed long before it had a chance to succeed.
A common pattern in industrial marketing: a manufacturer runs Google Ads for six or eight weeks, sees a high cost per lead and very little attributed revenue, and switches it off. The conclusion is that paid search does not work for their market.
Often the campaign was fine. The measurement was not.
Why long sales cycles break default reporting
Google Ads records a conversion inside a conversion window — a set period after the click during which an action still counts as attributable to that click. The default window is designed around the majority of advertisers, who sell things that people buy quickly.
Industrial purchasing does not work that way. A buyer finds a supplier, downloads a spec, sends a drawing, waits for an estimate, compares quotes, gets internal approval, and places an order. That sequence routinely runs for months.
If the window closes before the deal does, the revenue is never attributed to the click that started it. The campaign generated the opportunity and gets no credit — so the report shows spend with little return, and the account gets paused.
What that looks like in practice
Cost per lead appears far too high, because only the fastest-converting enquiries land inside the window. The genuinely valuable enquiries — the ones that turn into repeat orders — arrive too late to be counted.
Worse, Google’s automated bidding learns from the conversions it can see. If it only sees quick, low-value actions, it optimises toward more of those. The account drifts toward the wrong kind of enquiry, and the drift looks like improvement in the dashboard.
What to change
Extend the conversion window to match reality
Conversion windows are configurable. Set yours against how long your deals actually take, measured from your own records rather than an assumption. If typical enquiries close in three or four months, a window shorter than that is guaranteed to under-report.
This single setting often explains most of the gap between what an account appears to produce and what it actually produced.
Feed real outcomes back into the account
Google Ads can accept offline conversion data — the outcome of an enquiry once your team knows whether it became a quote, an order or nothing. Importing that back means the bidding algorithm optimises toward enquiries that turned into business, rather than toward form fills.
For manufacturers this matters more than for most advertisers, because a form fill and a viable RFQ are very different things and the ads platform cannot tell them apart on its own.
Track the enquiry, not just the click
Quote requests, spec downloads and phone calls should all be tracked as distinct actions with different values. Treating every form submission as one undifferentiated “conversion” hides the signal you need.
Give it long enough to read
An account serving a months-long sales cycle cannot be judged in a fortnight. Restructuring campaigns every two weeks because cost per lead looks high prevents the account from ever accumulating enough data to optimise against.
Where paid search fits alongside organic
Paid search is demand capture. It reaches buyers who are already looking, which makes it useful for testing which capabilities and messages actually generate enquiries — information that then improves the rest of your site.
It does not compound the way organic search does. A capability page that earns its ranking keeps producing enquiries without per-click cost; an ad stops the moment the budget does. Most manufacturers are best served by both, with paid search funding the slower organic work rather than replacing it.
Before increasing spend
If paid search has underperformed for you before, check the measurement before concluding the channel is wrong. Look at the conversion window, whether offline outcomes are being imported, and whether every enquiry type is tracked separately.
Those three settings determine whether the numbers you are looking at describe your campaign or merely describe its first thirty days.
