What should a plumbing company add as negative keywords in Google Ads?<\/h2>\n
Negative keywords stop your ads from showing on searches you’d never want to pay for, and for plumbers the usual starting list covers do-it-yourself and how-to searches, plumbing jobs and training, parts and supply shopping, and services or areas you don’t cover. Google lets you add them to a campaign, a shared list or the whole account, and they don’t catch plurals or synonyms automatically, so add those yourself. Then read the search terms report every week, because the most useful negatives come from the searches your ads actually matched.<\/p>\n
Building and pruning negative keyword lists is part of the Google Ads management in our local ads<\/a> work, and every package includes call tracking so wasted clicks show up as cost per lead, not a mystery. How that fits a plumbing shop is on our plumbing marketing<\/a> page, and the rest of the plumbing marketing questions<\/a> library goes question by question.<\/p>\n A negative keyword tells Google Ads not to show your ad when a search contains that term. Google describes negative keywords as a way to exclude search terms from your campaigns<\/a> and focus on the keywords that matter to your customers, and suggests looking for searches that are similar to your keywords but come from people looking for something else.<\/p>\n For a plumber, “something else” is usually a person who wants to fix the problem themselves, wants a job as a plumber, or wants to buy a part. Every one of those clicks costs the same as a click from someone with a leaking water heater, so blocking them moves the same budget toward people who might call. Whether that turns into booked jobs still depends on your ads, your landing page and who answers the phone. If you’re here because your ads get clicks but no calls, why plumbing ads get clicks but no calls<\/a> treats negatives as one of five checks; this page is the full process for building and keeping the list.<\/p>\n In our judgement, most plumbing companies can start with four themes and adjust them to their own business:<\/p>\n Treat this as a starting point, not a list to paste in. A word that’s junk for one shop is a job for another: if you sell and install water softeners, “water softener” belongs in your keywords, not your negatives. What keywords plumbing Google Ads should target<\/a> covers the other side of the list.<\/p>\n Blocking too much is the quieter mistake, because you never see the calls you didn’t get. In our judgement, be careful with:<\/p>\n Before you add a negative, search your own keyword list for it. If it appears in a keyword you’re paying for, the negative will stop that keyword from showing on searches that contain it.<\/p>\n Negative keywords have the same three match types as regular keywords, but Google says they work differently from their positive versions<\/a>. The illustrations below use plumbing words; the rules are Google’s.<\/p>\n For most plumbing negatives, broad or phrase is what you want, because junk searches come in many versions. Exact is for blocking one specific search without touching its neighbors.<\/p>\n Plurals and synonyms, yes. Google says negative keywords won’t match close variants<\/a>: in its own example, a negative for “flowers” blocks “red flowers” but not “red flower”. So “job” and “jobs”, “career” and “careers”, “part” and “parts” each need adding.<\/p>\n Misspellings and capital letters, no. Google says negative keywords automatically account for casing and misspellings, so you don’t need “Plumbing Jobs” or “plumming jobs” as separate entries. That’s a difference from what many owners expect, and it’s why a negative list built from one word per theme leaks.<\/p>\n Google Ads gives you several places to put them, and each fits a different job:<\/p>\n That last use is about structure as much as waste. How to structure plumbing Google Ads campaigns<\/a> covers how campaigns divide the work.<\/p>\n The search terms report<\/a> shows the actual searches that triggered your ads. Google’s steps for turning those into negatives<\/a>:<\/p>\n One detail to watch: Google says negatives added from the search terms report to a Search campaign are added as negative exact match<\/strong> by default. That blocks only that exact search. If the search was “how to fix a running toilet”, you probably want to block “how to” more broadly, so change the match type or add the theme word to your list as well.<\/p>\n For Performance Max, yes. Google lets you add negative keywords to Performance Max campaigns<\/a>, at the campaign or account level, and they apply to Search and Shopping inventory only. Google also offers a way to estimate the impact of a negative before you add it.<\/p>\n Local Services Ads work differently: you pay per lead, not per click, and the fix for a bad lead is usually a dispute or a settings change rather than a keyword. Disputing bad Local Services Ads leads as a plumber<\/a> covers that side.<\/p>\n In our judgement, weekly for the first two or three months of a campaign, then at least monthly. New campaigns turn up the most surprises, especially on broad match. Seasonal changes bring new junk too: a cold snap brings a wave of “how to thaw a frozen pipe” searches alongside the real emergencies.<\/p>\n Review the list itself as well as the searches. Every few months, check whether a negative is blocking something you now want, for example if you’ve started offering a service you used to exclude.<\/p>\n Not every junk call is a keyword problem. Calls for services you don’t offer can come from an ad that’s too vague, a landing page that lists everything, or location settings that reach people outside your area. Price shoppers can come from ads that lead with a discount. Sales calls and spam can come from any phone number you publish.<\/p>\n Negative keywords fix one cause: paying for the wrong searches. Cutting down on junk plumbing leads<\/a> covers the others, and if your ads get clicks but the phone stays quiet, why plumbing ads get clicks but no calls<\/a> walks through what to check.<\/p>\n A free visibility audit shows where you show up on Google, Maps and AI answers, and what it's costing you in calls.<\/p>\n<\/div>\n Plumbing is a do-it-yourself trade first.<\/strong> Clogs, running toilets and dripping faucets are problems many people try to fix before they call anyone, so plumbing keywords pull in more how-to and parts searches than most trades. The DIY theme is usually the first and biggest list.<\/p>\n Emergencies and research use the same words.<\/strong> “Burst pipe” can be someone with water on the floor or someone reading about winter prep. Negatives work on words like “how to”, “prevent” and “insulate” rather than on the problem itself, so the emergency searches stay in.<\/p>\n The trade has a big jobs market.<\/strong> Apprenticeships, licensing exams and plumber job openings all use the same words as your services, and none of them are customers.<\/p>\n Service menus differ a lot between shops.<\/strong> One plumber does septic, wells and gas lines; the next does none of them. A borrowed negative list will block someone’s paying work, so build yours from your own price book.<\/p>\n These numbers are made up to show the math, not a benchmark for your market. Say your plumbing campaign got 320 clicks last month at an average of $15 a click, or $4,800. You open the search terms report and sort the searches into themes:<\/p>\n That’s 96 clicks, or 30% of the month’s clicks, at a cost of $1,440, that were never likely to become customers. Adding negatives for those themes (with plurals and synonyms) means next month that money can go to other searches instead.<\/p>\n Two cautions. The $1,440 isn’t guaranteed savings or new jobs; it’s budget that’s free to reach better searches, and you still judge the result by booked jobs. And before adding each negative, check it doesn’t appear in a keyword you’re paying for. A free visibility audit can show how your ads and your competitors’ show up for the searches you want.<\/p>\n Yes. If a negative matches a search that also matches one of your keywords, the ad won’t show for that search. Check each new negative against your keyword list before you add it.<\/p>\n Only if you’re paying for searches that include them and they aren’t booking. If you aren’t bidding on those searches at all, there’s nothing to block.<\/p>\n Google doesn’t describe them that way. They stop your ads from showing on searches you exclude, which changes where your budget goes rather than the price of each click.<\/p>\n Google allows ampersands, accent marks and asterisks, ignores periods and most plus signs, rejects some other symbols, and strips the site: operator, so negatives work on the search words themselves.<\/p>\n The search terms report is Google’s main tool for finding them, and for Performance Max you can estimate the impact of a negative before adding it. Read the searches yourself rather than adding anything in bulk.<\/p>\n A starting list helps, but no list fits every shop, because services differ. Build yours from your own search terms report and price book, and expect it to change over the first few months.<\/p>\n Start with a free visibility audit: rankings, Google profile, reviews and tracking, checked against your service area.<\/p>\n<\/div>\n Which negative keywords plumbers should add in Google Ads: DIY, jobs, parts and services you don’t offer, plus match types, plurals and where to put them.<\/p>\n","protected":false},"author":2,"featured_media":1612,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_canonical":"","ll_review_state":"approved","ll_template_version":"v1","ll_sources":"[\"https:\/\/support.google.com\/google-ads\/answer\/2453972?hl=en\", \"https:\/\/support.google.com\/google-ads\/answer\/2453983?hl=en\", \"https:\/\/support.google.com\/google-ads\/answer\/11396330?hl=en\", \"https:\/\/support.google.com\/google-ads\/answer\/15726455?hl=en\", \"https:\/\/support.google.com\/google-ads\/answer\/7102466?hl=en\", \"https:\/\/support.google.com\/google-ads\/answer\/2472708?hl=en\"]","ll_faq":"[{\"q\": \"Can negative keywords block my ads from showing on my own keywords?\", \"a\": \"Yes.
