Roll-up of spend on zero-conversion search terms, the cleanest recoverable line in the account.
At a glance
Spend on search terms and keywords that produced zero conversions over the window. The cleanest recoverable line item in any Google Ads account, every pound here is, by definition, recoverable on the next negative-keyword sweep or campaign pause.
Calculation
Calculated automatically from your Google Ads data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.Worked example
A UK fashion brand with £27,400 of total Google Ads spend over the 30-day window covering 14 Mar 26 to 12 Apr 26. The wasted-spend roll-up flags £1,840 (6.7% of total spend) as zero-conversion.
What a paid-acquisition lead does with this:
- The £1,840 is fully recoverable. Adding three negative keywords (
free,size 22+, competitor name) recovers ~£1,220 immediately, without touching campaigns. This is the highest-leverage 15 minutes of the week. - 6.7% wasted is healthy. Industry typical sits at 8-15% of spend on zero-conversion search terms. Below 5% suggests over-aggressive negative-keyword pruning (you may be blocking legitimate long-tail traffic). Above 15% means the account needs a sweep.
- Display Remarketing zero-conversion is not always wasted. If the audience is small and the spend is small (< £500/mo), it can be the cost of staying visible to people who would not convert via paid anyway. Use ROAS by Campaign to confirm whether the campaign has any periodic conversion at all.
- A search term with 1 click and 0 conversions is NOT the signal. The 30-day window matters precisely because some keywords need 30-50 clicks before a conversion is statistically expected. Acting on a 1-click zero-conversion line is noise. Filter to spend > £50 before pausing.
- Wasted spend will rise during promo cycles. A 25%-off campaign attracts price-sensitive bargain hunters who click everywhere and convert nowhere; expect this card to inflate by 30-50% during sales weeks. Don’t over-react.
- Wasted spend > 15% of total: account needs a negative-keyword sweep. See Search Terms.
- A single search term > £200 wasted: highest-priority single fix.
- Wasted spend rising while account ROAS holds: traffic mix is shifting; review match types (broad match leakage is the usual cause).
- Wasted spend zero or near-zero: probably over-pruned; check whether you have killed long-tail growth.
Sibling cards merchants should reference together
Reconciling against the vendor’s own dashboard
Where to look in Google Ads UI: Google Ads > Insights and reports > Search terms. Sort by Cost descending and filter Conversions = 0. The total at the foot of that view should match this card to within 1-2%. Google Ads > Keywords > Search keywords with Conversions = 0 filter is the keyword-level equivalent. Other Google Ads views that look like the same number but aren’t:- All conv. = 0: includes view-through. This card uses primary conversions only, so the All-conversions filter will mark fewer terms as wasted.
- Search Terms with 1+ conversions: not in this card. Some shops mark a £5,000-spend / 1-conversion term as wasted (CPA too high), but that is a separate concept (see CPA Trend).
- Display placements report: Google Ads has a separate placements view for Display campaigns; this card aggregates Display campaigns at the campaign level, not at the placement level.
- Negative keyword conflicts: if you have negatives blocking high-intent queries, those don’t appear here (Google didn’t bid on them). They are missed opportunity, not wasted spend.
Why the BUSINESS metric often differs (the IMPORTANT one):
The “wasted” label assumes Google’s
conversions_value is the truth. In practice, a search term marked here as zero-conversion may have:
- Driven a conversion that the pixel missed. Tag-fire failures on specific landing pages (mobile-only checkout glitches, JS errors) cause pixel under-reporting. Cross-check against Clicks vs Conversions and the commerce platform’s UTM-tagged orders.
- Driven an offline conversion (phone call, in-store) that the merchant doesn’t import into Google Ads. Common for services, less common for ecom.
- Driven a multi-touch path where Google Ads was the first click and got no last-click credit. The session value is captured by the closing channel, not Google Ads. Cross-check with GA4 Path Analysis before pausing.
- Driven a conversion that closed outside the attribution window. Default 7-day click window; a high-consideration product (jewellery, furniture) may convert at day 14 and never appear here as the cause.
