The 80/20 keyword pruning cadence is a regular routine of finding keywords that have spent meaningfully without producing a step-one conversion and pausing them. A useful trigger is a keyword that has spent roughly $800–$1,000 over ~30 days with zero conversions. Running this cadence consistently keeps the account lean, stops budget leaking into dead terms, and feeds smart bidding cleaner signal.
Every account accumulates dead weight: keywords that looked promising, never converted, and quietly kept spending because nobody circled back to check. Individually they’re small; collectively they’re a meaningful chunk of wasted budget, and they muddy the signal your bidding learns from. Pruning them isn’t a one-time cleanup — it’s a cadence.

The 80/20 idea: a small set of terms causes most of the waste, and a regular routine catches them before they run for months.
The pruning rule
Set a clear, defensible trigger so pruning is objective rather than a gut call. A common one: any keyword that has spent a meaningful amount — say $800–$1,000 over the last 30 days — without producing even a first-step conversion is a candidate to pause. The exact numbers scale to your account; the point is a threshold, applied consistently, that catches spenders that don’t earn.

Why cadence beats cleanup
A once-a-year purge lets dead keywords run for months before anyone notices. A regular cadence — weekly or biweekly — catches them early, so the waste is measured in days, not quarters. Consistency is the whole advantage: the same modest threshold applied often removes far more waste over a year than a big occasional audit.
| Annual purge | Regular pruning | |
|---|---|---|
| Dead keyword runtime | Months | Days |
| Waste caught | Late | Early |
| Signal quality | Muddied | Clean |
| Effort per pass | Large | Small |
Prune with judgment
Threshold triggers a review, not an automatic delete. Check for conversion lag (a slow market may just need more time), seasonality, and tracking gaps before pausing — a keyword with no recorded conversions because tracking broke isn’t a dead keyword. And consider negatives and match-type fixes alongside pausing, so you’re addressing the query, not just the symptom.
Every review cycle, pull the spenders with no conversions, sanity-check for lag and tracking, then pause the genuine dead weight. Small, often, forever.
What’s spending without earning?
Pull your keywords sorted by spend, filter to those with no meaningful conversions in the window, and you’ll usually find the same few culprits quietly bleeding budget. Prune them on a cadence and the account stays lean — and the algorithm learns from cleaner data.
