To add negative keywords in Google Ads, open Campaigns, then Insights and reports, then Search terms, and sort by cost. Tick each search that cost money and could never become a customer, select Add as negative keyword, and choose the ad group, the campaign or a negative keyword list. Check the match type before you save, because from this report Google adds it as negative exact unless you change it.
A keyword is what you bid on. A search term is what someone actually typed, and every click you pay for comes from a search term. This guide takes it one step at a time.
A keyword or a search term?
Google puts the difference in two sentences. “A keyword is a word or set of words that Google Ads advertisers can add to a given ad group so that your ads are targeting the right audience.” And “A search term is a word or set of words a person enters when searching on Google or one of our Search Network sites.” You choose the first; your customers choose the second. A negative keyword is how you tell Google which search terms to leave out.
The six steps
1Know how far each keyword reaches
CampaignsAudiences, keywords, and content
A keyword is what you bid on; a search term is what someone typed. How far a keyword reaches depends on its match type. Broad match, the default: “Ads may show on searches that are related to your keyword, which can include searches that don’t contain the direct meaning of your keywords.” Phrase match, in quote marks: “Ads may show on searches that include the meaning of your keyword.” Exact match, in square brackets: “Ads may show on searches that have the same meaning or same intent as the keyword.” So a broad keyword for leather couches can be shown to someone who wants a couch repaired.
2Open the search terms report
CampaignsInsights and reportsSearch terms
It lists the searches that showed your ads: “the search terms that were used by a significant number of people and have triggered impressions and clicks.” Searches made by only a few people are left out: “Some search terms that don’t have enough query activity are omitted from the search terms report in order to keep with our standards on data privacy.” So the report is most of the picture, not all of it.
3Read cost against conversions
ColumnsKeyword
Each row is a real search. Read what it cost beside what it brought. Turn on the Keyword column, because “The "Keyword" column doesn’t show by default.” It tells you which of your keywords matched the search. The row you are looking for is money spent on people who want something you do not sell.
4Add it as a negative keyword
Tick the search termAdd as negative keyword
“Negative keywords let you exclude search terms from your campaigns and help you focus on only the keywords that matter to your customers.” Tick the search term, select Add as negative keyword, then choose where it goes: the ad group, the campaign, or a negative keyword list. Read the match type before you save, because “By default, negative keywords added to a Search campaign from the search terms report are added as negative exact match.” Exact blocks that one search. To block every search with the word repair in it, add repair on its own as negative broad.
5Pick the negative match type on purpose
Negatives match differently from keywords, and negative broad is the default. The three types are set out below.
6Keep one list that guards every campaign
AdminAccount settingsNegative keywords
A negative keyword list holds your negatives once and applies to as many campaigns as you choose: “You can add up to 5,000 negative keywords per list, and create up to 20 negative keyword lists in your account.” There is also one account level list, in Account settings, for search and shopping inventory in every campaign, and “A limit of 1,000 negative keywords can be excluded for each account.”
How each negative match type blocks
Negative broad is the default. Each type below is in Google’s words.
- Negative broad (the default). “For negative broad match keywords, your ad won't show if the search contains all your negative keyword terms, even if the terms are in a different order.”
- Negative phrase. “For negative phrase match keywords, your ad won't show if the search contains the exact keyword terms in the same order.”
- Negative exact. “For negative exact match keywords, your ad won't show if the search contains the exact keyword terms, in the same order, without extra words.”
All three from Google Ads Help, About negative keywords.
Three things a negative keyword does not do
- It does not match close variants. “Negative keywords won’t match to close variants or other expansions.” Google’s example: exclude the negative broad keyword flowers, and “ads won’t be eligible to serve when a user searches "red flowers", but can serve if a user searches for "red flower".” Add the singular and the plural yourself.
- It does not need your misspellings. “Negative keywords automatically account for casing and misspellings, so you don’t need to add those separately.”
- It does not come free. “If you use too many negative keywords, your ads might reach fewer customers.” Block what you do not sell, not every search you did not expect.
Read the report the other way too
A search that brings customers and is not one of your keywords yet is worth adding as one, so you can bid on it directly instead of reaching it through a broader keyword.
One question for a campaign you already run
Open the search terms report for the last 30 days and sort by cost. Which search cost the most, and brought nothing?
The film, as text
Chapter 4 of the course, word for word, as it is spoken in the film above. The account in the film is an example.
Your keywords are not what people searched. A keyword is what you bid on. A search term is what someone actually typed. And every click comes from a search term. In this chapter, we open the report that lists them, find the ones that cost money and could never become customers, and block them. The report. The negative keyword. How it matches. And one list that guards every campaign.
This is chapter four of a free course on running Google Ads yourself. Chapter three made sure your account counts customers. This one is about the searches you pay for. Every rule here is quoted from Google's own help pages.
Step one. Keywords and search terms. In Google's words, a keyword is a word or set of words that advertisers add to an ad group, so their ads target the right audience. How far a keyword reaches depends on its match type. Broad match is the default. Google says ads may show on searches that are related to your keyword. Phrase match, in quotes, shows on searches that include the meaning of your keyword. Exact match, in square brackets, on searches with the same meaning or intent. So the broad keyword leather couches can show on a search for leather couch repair. That's a click you pay for, from someone who wants a repair.
Step two. Open the search terms report. In Google Ads, select Campaigns, then Insights and reports, then Search terms. In Google's words, it shows the search terms that were used by a significant number of people, and have triggered impressions and clicks. Searches made by only a few people are left out, to protect their privacy. So the report is most of the picture, not all of it.
Step three. Read it. Each row is a real search. Read the cost and the conversions beside it. Turn on the Keyword column, which doesn't show by default. It tells you which of your keywords matched the search. Here, leather couches denver cost money and brought two customers. Leather couch repair near me cost forty one dollars, and brought none. That's the row you're looking for: money spent on people who want something you don't sell.
Step four. Block it with a negative keyword. In Google's words, negative keywords let you exclude search terms from your campaigns. Tick the search term, and select Add as negative keyword. Then choose where it goes: the ad group, the campaign, or a negative keyword list. From this report, Google adds it as negative exact match, unless you change it. Exact blocks that one search. To block every repair search, add the word repair on its own, as negative broad.
Step five. How negatives match. Negative broad is the default. Your ad won't show if the search contains all your negative keyword terms, even in a different order. Negative phrase blocks the terms in the same order. Negative exact blocks only the exact terms, in the same order, without extra words. And one difference to remember. Negative keywords won't match close variants. Exclude flowers, and a search for red flower can still show your ad. So add the singular and the plural yourself. Capital letters and misspellings are handled for you.
Step six. One list for every campaign. A negative keyword list holds your negatives once, and applies them to many campaigns: up to five thousand per list, and twenty lists per account. There's also one account level list, in Account settings, for all your search and shopping inventory, up to one thousand negatives. One warning from Google: if you use too many negative keywords, your ads might reach fewer customers. And read the report the other way too. A search that brings customers, and isn't one of your keywords yet, is worth adding as one.
The search terms report, before you spend. Know your match types. Open the report every week. Read cost against conversions. Block what you don't sell, with the right match type, and the plural too. And keep one list that guards every campaign.
Here's a question you can answer right now, if you already run a campaign. Open the search terms report for the last thirty days, and sort by cost. Which search cost the most, and brought nothing?
