Bulk negative keywords in Google Ads: adding hundreds of terms in one request
Building a negative list from the search terms report, choosing the right match type, deciding between campaign and shared lists, and three common mistakes.

Find the terms before you write the list
A negative list is written from the search terms report, not from guesswork. The opening question is: which terms received clicks without converting in the last 30 or 60 days, sorted by spend. In Tecrube that is a read; you ask Claude or ChatGPT in one sentence, it spends no credits and needs no approval.
Group the list by intent: information seekers such as “free”, “pdf” or “how to”; job seekers such as “salary”, “vacancy” or “course”; brands and models unrelated to what you sell. Each group calls for a different decision.
Which match type?
Match types on negatives work the opposite way to positive keywords and are narrower: negative broad match does not cover close variants, and singular and plural count separately. Writing “cheap” does not automatically block “cheaper” or “cheapest”.
A practical rule: negative broad for single-word off-intent terms, phrase for expressions containing a product name where you only want a specific combination blocked, exact to shut down one precise search. Ask the assistant to propose the list with match types according to this rule.
Which level to write at
Terms you never want anywhere in the account, such as “free” and “vacancy”, go into a shared negative list applied once across all campaigns. Terms that cause trouble in only one campaign stay at that campaign's level.
Ad group level is for steering traffic between groups, so that a “leather sofa” search does not land in the fabric sofa group. Mixing the three levels makes it hard to find where a term is blocked; decide the purpose of each level up front.
What bulk adding looks like in practice
Say a kitchen equipment store has found 140 off-intent terms. The command reads: “add these terms to the ‘General negatives’ shared list with the match types I noted next to each; add the brand names to the Search campaign only”.
Tecrube gathers the request into one preview: which list or campaign, how many terms, which match types; conflicting or already existing terms are flagged separately. On approval the whole addition is applied in a single operation and written to the audit log. If a wrong term shows up in the preview you back out and nothing changes.
Three common mistakes
First, blocking your own converting terms. Single-word broad negatives are dangerous: a “rental” negative also kills “rent-to-own purchase”. Compare the term list in the preview against the terms that currently convert.
Second, blocking competitor brands by reflex. A competitor search is sometimes the cheapest conversion in the account; look at the data first. Third, writing the list once and forgetting it. Search terms change every month, so make the same question a monthly routine. To find a negative added by mistake, list the audit log from chat and search for the term.
Limits and getting started
Google caps the number of negatives per campaign and per shared list; most accounts never get close, but on lists of thousands of terms the preview warns you. The 75 credits on the free account cover several search term analyses and bulk additions; Pro includes 5,000 credits a month and Agency is unlimited.
Make your first bulk addition with a small list of twenty or thirty terms; move on to lists of hundreds once you are used to the preview and audit log flow.
Singular, plural and spelling variants
Because negative keywords do not cover close variants, singular and plural forms must be added separately. A “course” negative does not block “courses”; in languages with rich suffixes such as Turkish, every suffixed form counts as a separate term. Asking the assistant to add common inflected forms to single-word negatives is a good habit.
The same applies to typos and accented characters. Users may type “free”, “freebie” or a misspelling; each is a separate negative. A request such as “add free, freebie, for free and no cost to the shared list as negative broad” shows every term in one preview.
Do not overdo it: blindly blocking every variant can shut out a purchase-intent search. Asking the assistant to compare the preview list against the terms that converted in the last 90 days keeps that risk to a minimum.
Because the preview shows existing and newly added terms separately, you never add the same variant twice.
