Should a Negative Keyword Go on the Account, Campaign or a Shared List?

You've found a junk query in one campaign's search terms report, and excluding it takes one click. The real decision is where it goes. Add it to that campaign and you'll add it again next month in four others. Add it account-wide and it reaches campaigns you weren't thinking about.

Place each negative by how widely the query is wrong. Queries that are wrong for the whole business, such as job searches, go on the account-level list, which also reaches Performance Max. Queries that are wrong for a group of campaigns go on a shared negative keyword list. Queries that are fine but land in the wrong campaign stay at campaign or ad group level.

What does each placement actually reach?

The three placements differ in one thing: how a campaign comes to be covered.

A campaign or ad group negative affects only the campaign or ad group it sits in. Nothing else sees it. That precision is the point, and it is also the cost. An exclusion needed in five campaigns has to be entered five times, and every new campaign starts with none of them.

A shared negative keyword list is built once and attached to campaigns. A term added to the list applies immediately to every campaign linked to it. A list attached to nothing does nothing, so coverage depends on someone remembering to link each new campaign.

The account-level list needs no attachment. Google's help documentation on account-level negative keywords says it applies to all search and shopping inventory across Search, Performance Max, App, Shopping, Smart and Local campaigns. A campaign launched tomorrow inherits it automatically. At the time of writing, the list is capped at 1,000 negative keywords per account.

So the choice comes down to reach. A negative can cover one campaign, a set you choose, or everything, including campaign types where you have far less control over individual queries.

Which terms belong on the account list?

Only terms that would be wrong for any campaign you could plausibly launch, including ones you haven't thought of yet. That is a high bar, and it should be.

Good candidates describe a searcher you never serve. "Jobs," "careers" and "salary" are wrong for almost every business that isn't recruiting through its ads. "Repair," "service" and "hire" are wrong everywhere for a retailer that sells products and offers no services. No campaign, current or future, has a use for those clicks.

The trap is terms that feel universal but aren't. "Free" is junk for a premium product, but it may describe your best prospect if you run a free trial. "Cheap" is wrong for your luxury line and fine for the outlet campaign you might add next season. Put either on the account list and you have made that decision for every campaign, Performance Max included.

An over-broad account negative is also the hardest kind of blocked query to notice. The searches it removes never show up in a report, which is why it pays to check periodically whether your negatives are blocking searches that bring customers.

The cap is a second reason for restraint. Negatives don't expand to close variants, so plurals and common misspellings each need their own entry, and 1,000 slots fill faster than the number suggests. Spend them on terms that are wrong everywhere.

When is a shared list the better home?

When an exclusion is right for several campaigns but not all of them. That describes most of the negatives worth keeping, and it is the placement most accounts underuse.

A B2B software company might exclude "personal," "home" and "student" across its prospecting campaigns but leave them off the campaign that sells education pricing. A retailer might exclude competitor brand names from every campaign except a deliberate conquest campaign. In both cases the term is wrong for a group, and you decide who is in the group.

Shared lists also fix the drift that comes from adding the same terms campaign by campaign. Without them, campaigns built in March carry the full set, campaigns built in June carry half, and nobody can say which is which. One list maintained in one place removes that inconsistency.

Split lists by theme rather than building one catch-all. A list attaches to a campaign as a whole. A single list that mixes competitor names, wrong-intent terms and vertical junk forces every campaign to take all of it or none of it. Separate lists for wrong intent, competitors and brand safety let each campaign take only what fits.

Give each list a clear name and an owner, and review it on a set schedule. For an agency, a standard set of lists per client means a new account manager doesn't have to rebuild the exclusions from memory.

When should a negative stay on one campaign?

When the query isn't bad, just in the wrong place. These negatives route traffic between your own campaigns instead of keeping it out of the account.

Brand and non-brand is the common case. Adding your brand terms as phrase and exact negatives in the non-brand campaign does three things:

• Brand searches go to the brand campaign.
• The two campaigns stop bidding against each other.
• Cheap brand conversions stop flattering the non-brand numbers.

Closely related offerings work the same way. Two campaigns for overlapping products need targeted exclusions, or each dilutes the other.

The same logic applies one level down. A generic "shoes" ad group next to color-specific ad groups will pick up "blue shoes" searches meant for the blue group, unless the color is a negative in the generic group. Location ad groups need each other's place names excluded for the same reason.

None of these belong on a shared list or the account. Put "blue" at account level and you block the searches the blue ad group exists to win.

How do you place a new negative quickly?

When a term comes out of the search terms report, ask three questions in order:

1. Would any campaign, now or plausibly later, want this click? If not, the term goes on the account list.
2. Is it wrong for a definable group of campaigns? Add it to the shared list for that theme, and check the list is attached where it should be.
3. Is the click fine but landing in the wrong campaign or ad group? Make it a negative there and nowhere else.

Asking them in that order makes the narrowest placement that works your default. That is the safer way to be wrong. A term placed too narrowly leaks a little spend that you'll see again in the report. A term placed too broadly removes traffic you'll never see at all.

One check for Performance Max: the account-level list is the placement Google documents as reaching it. Don't assume a shared list or campaign negative built for Search covers a Performance Max campaign. Confirm it in the account before relying on it.

Placement is the second decision. The first is which search terms are wasting budget at all.

Conclusion

Where a negative keyword goes is a decision about scope, not tidiness. The account list is for queries no campaign will ever want. Use it sparingly, because it reaches everything and has a hard cap. Shared lists do most of the work for exclusions that fit a defined group, and campaign and ad group negatives handle routing. Start with the narrowest placement that works, and widen it only when you're sure the query is wrong more broadly.

If what counts as wrong intent differs from client to client, see how SproutMe Knowledge holds each workspace's ICP and positioning in one place, so the definition behind a shared list is written down rather than remembered.
