How to Add Negative Keywords to All Campaigns: A Complete Step-by-Step Guide

You've just checked your Google Ads account and discovered something frustrating: a chunk of your budget went to searches like "how to make my own [product]" or "[competitor name] reviews" or "free [service] templates." These clicks cost you money but had zero chance of converting because the searcher wasn't looking to buy—they were looking for free alternatives, competitor info, or DIY solutions.

This is where negative keywords become your budget's best friend. They tell Google Ads which searches should never trigger your ads, filtering out the tire-kickers and window-shoppers so your budget goes toward people who actually want what you're selling.

The challenge? If you're managing multiple campaigns, adding negative keywords one campaign at a time is painfully slow. You'd spend hours copying and pasting the same terms into campaign after campaign, knowing you'll probably miss a few along the way.

Here's the good news: Google Ads has a built-in feature that lets you add negative keywords to all your campaigns at once using shared negative keyword lists. One update, instant application across your entire account. Whether you're running three campaigns or thirty, you can protect your budget from irrelevant searches in minutes, not hours.

This guide walks you through the complete process: how to find which searches are wasting your money, how to organize your negative keywords strategically, and how to apply them across all campaigns efficiently. You'll also learn when to use campaign-specific negatives for more precise control, and how to maintain your negative keyword strategy over time so new junk terms don't slip through.

Let's stop paying for clicks that will never convert.

Step 1: Pull Your Search Terms Report to Find What's Costing You Money

Before you can add negative keywords, you need to know which searches are actually triggering your ads. This is where the Search Terms Report becomes essential—it shows you the exact queries people typed before clicking your ads, not just the keywords you're bidding on.

To access it, navigate to Insights & Reports in the left sidebar of Google Ads, then click Search terms. This report displays every search query that triggered your ads during your selected date range.

Start by adjusting your date range to capture meaningful data. For most accounts, the last 30 to 90 days provides enough volume to spot patterns without overwhelming you with data. If you're managing a high-spend account, 30 days might be sufficient. Smaller accounts benefit from looking at 60-90 days to gather enough search queries for analysis.

Now comes the detective work. Sort the report by Cost to see which searches are consuming the most budget. Look for terms that clearly don't match your offering—things like "free," "DIY," "how to make," competitor names, or completely unrelated products. These are your low-hanging fruit: terms that are costing you money but have zero conversion potential. Learning how to find negative keywords in Google Ads systematically will help you identify these budget-draining terms faster.

Next, sort by Impressions to catch high-volume irrelevant terms that might not have cost much yet but will drain your budget if left unchecked. A search term with 5,000 impressions and a 2% click-through rate could generate 100 clicks—that's potentially hundreds of dollars wasted if those clicks never convert.

Pay attention to patterns, not just individual terms. If you see multiple variations of "jobs," "careers," "hiring," and "salary," you're attracting job seekers, not customers. If "tutorial," "guide," and "how to" keep appearing, you're catching people in research mode, not buying mode. These patterns tell you which categories of negatives you need to build.

Step 2: Categorize Your Negative Keywords by Intent and Theme

Once you've identified your problem searches, resist the urge to immediately start adding them as negatives. Taking 15 minutes to organize them first will save you hours of management down the road.

Create logical categories based on searcher intent and themes. Common categories include: Job Seekers (jobs, careers, hiring, salary, employment), Free/DIY (free, DIY, how to, tutorial, template), Competitors (competitor brand names and product names), Wrong Products (products or services you don't offer), and Informational Queries (what is, definition, examples, comparison). Understanding common negative keywords every campaign should have gives you a head start on building these categories.

Why categorize? Because you'll create separate shared negative keyword lists for each category, making them easier to manage and update. When you discover a new job-seeker term next month, you'll add it to your "Job Seeker Terms" list and it automatically applies to all campaigns using that list. No hunting through individual campaigns.

As you categorize, decide on match types for each negative keyword. This is where negative keywords work differently than regular keywords—and understanding the difference prevents accidentally blocking good searches.

Broad match negative blocks any search containing all your negative terms in any order. Adding "free software" as a broad match negative keyword blocks "free software tools," "software free download," and "best free software," but still allows "software" or "free trial" to trigger your ads.

Phrase match negative blocks searches containing your exact phrase in that order, but allows additional words before or after. Adding "how to" as a phrase match negative blocks "how to build a website" but still allows "website builder" to trigger ads.

Exact match negative only blocks that precise query with no additional words. This is rarely necessary—broad and phrase match negatives handle most situations more effectively. For a deeper dive into these distinctions, review how match types work for negative keywords.

For most negative keywords, start with broad match. It provides the widest protection without requiring you to anticipate every possible variation. Use phrase match when you need more precision—for example, blocking "free trial" without blocking "trial" by itself.

Create a simple spreadsheet with columns for the negative keyword, its category, and its match type. This becomes your master list that you'll reference as you build your shared lists in Google Ads.

Step 3: Create a Shared Negative Keyword List in Google Ads

Now you're ready to build the infrastructure that makes managing negatives across all campaigns effortless. Shared negative keyword lists live in your account's Shared Library and can be applied to multiple campaigns simultaneously—update the list once, and the changes instantly apply everywhere it's being used.

Click Tools & Settings in the top right corner of Google Ads (the wrench icon), then navigate to Shared Library and select Negative keyword lists. You'll see any existing lists here, or an empty state if this is your first time creating one.

Click the blue plus button to create a new list. Give it a descriptive name that clearly indicates what it contains—something like "Universal Exclusions," "Job Seeker Terms," "Free/DIY Queries," or "Competitor Names." Specific names make it obvious which list to update when you discover new negative keywords later.

Now add your categorized negative keywords to the appropriate list. You can type or paste them directly into the interface. If you're adding many terms at once, paste them as a list with one keyword per line. Google Ads will automatically detect this format and add them all simultaneously. If you need guidance on structuring these lists effectively, learn how to build a master negative keyword list that scales with your campaigns.

As you add each term, specify its match type using the standard notation: no symbol for broad match, quotation marks for phrase match ("like this"), or brackets for exact match ([like this]). If you don't specify, Google Ads defaults to broad match negative.

Google Ads allows up to 20 shared negative keyword lists per account, with up to 5,000 keywords per list. This is more than enough capacity for most accounts—even large ones managing hundreds of campaigns.

Here's why shared lists are superior to adding negatives directly to campaigns: imagine you discover a new competitor next month. With shared lists, you add that competitor's name to your "Competitor Names" list once, and it immediately blocks that term across all 50 campaigns using that list. Without shared lists, you'd need to open each of those 50 campaigns individually and add the negative keyword 50 times. The time savings compound with every update you make.

Create multiple lists based on your categories rather than one giant list containing everything. This gives you flexibility—you might want job-seeker terms blocked everywhere, but competitor names only blocked in certain campaigns where you're not running conquest strategies.

Step 4: Apply Your Shared List to All Campaigns at Once

You've built your shared negative keyword lists—now comes the satisfying part where you apply them to all your campaigns with just a few clicks.

From the Negative keyword lists view in your Shared Library, find the list you want to apply. Click on its name to open the list details, then look for the Apply to campaigns button. Click it.

A modal window appears showing all campaigns in your account. This is where the magic happens: you can select multiple campaigns—or all campaigns—at once. Use the checkbox at the very top of the campaign list to select every campaign in your account with one click.

If you want to be selective, manually check the campaigns where this particular negative list should apply. For example, you might apply your "Universal Exclusions" list to every campaign, but only apply your "Enterprise Terms" list to campaigns targeting small businesses.

Once you've selected your campaigns, click Apply. The changes take effect immediately—there's no review period or delay. Your ads will stop showing for those negative keywords right away.

To verify the application worked, navigate to any campaign you selected, click on Keywords in the left sidebar, then click the Negative keywords tab. You'll see your shared list displayed as a linked list, with a small chain-link icon indicating it's a shared resource. Click on the list name to see all the negative keywords it contains.

The beauty of this approach: you can apply the same shared list to as many campaigns as needed. Running 10 campaigns? Apply it to all 10. Launching a new campaign next week? Apply your existing shared lists to it in seconds. This is how you scale negative keyword management without drowning in repetitive tasks.

Step 5: Add Campaign-Specific Negatives Where Needed

Shared lists handle your universal exclusions beautifully, but sometimes you need negatives that only make sense for specific campaigns. This is where campaign-level negatives come in.

Common scenarios include: excluding "enterprise" or "large business" from campaigns targeting small businesses, blocking "cheap" or "budget" from premium product campaigns, or excluding specific product names from campaigns promoting different products. These terms aren't universally bad—they're just wrong for particular campaigns.

To add campaign-specific negatives, navigate to the campaign that needs them. Click Keywords in the left sidebar, then switch to the Negative keywords tab. Click the blue plus button to add new negative keywords directly to this campaign. For detailed instructions on this process, see our guide on where to add negative keywords in Google Ads.

Enter your negative keywords using the same match type notation as before. These negatives apply only to this campaign—they won't affect any other campaigns in your account, even if those campaigns target similar keywords.

You can also add negatives at the ad group level for even more precision. This is useful when different ad groups within the same campaign target distinct audience segments. For example, if one ad group targets "beginner" keywords and another targets "advanced" keywords, you might add "advanced" as an ad group-level negative to the beginner ad group, and "beginner" as an ad group-level negative to the advanced ad group.

To add ad group-level negatives, navigate to the specific ad group, click Keywords, then Negative keywords, and add them the same way you would at the campaign level. Just remember: ad group negatives only affect that ad group, not the entire campaign.

The hierarchy works like this: account-level shared lists apply to all selected campaigns, campaign-level negatives apply to all ad groups in that campaign, and ad group-level negatives apply only to that specific ad group. If a search matches any negative at any level, your ad won't show.

Use this hierarchy strategically. Keep your broad, universal exclusions in shared lists for easy management. Use campaign-level negatives for terms that only make sense to block in specific campaigns. Reserve ad group-level negatives for fine-tuning when you need surgical precision.

Step 6: Set Up a Regular Review Schedule to Catch New Junk Terms

Adding negative keywords isn't a one-time task—it's an ongoing optimization practice. New irrelevant searches appear constantly as Google's matching algorithms interpret your keywords in creative ways, and as search behavior evolves over time.

The frequency of your reviews should match your account's spend level and complexity. High-spend accounts—those investing thousands per month—benefit from weekly reviews. You're processing enough search volume that new patterns emerge quickly, and the cost of missing irrelevant terms for even a few days adds up. For smaller accounts spending hundreds per month, bi-weekly reviews strike a good balance between staying on top of waste and not over-investing time in optimization.

When you review, follow the same process from Step 1: pull your Search Terms Report, sort by cost and impressions, and look for new irrelevant queries that have appeared since your last review. The difference now is you have your categorization system and shared lists already built, so adding new negatives takes minutes instead of hours. Be aware of mistakes to avoid when managing negative keywords so you don't accidentally block profitable traffic.

As you find new negative keywords, add them to the appropriate shared list rather than to individual campaigns. This ensures all campaigns benefit from your discovery. Found a new job-seeker term? Add it to your "Job Seeker Terms" list and it immediately applies to all campaigns using that list.

Track your cost savings over time to measure the impact of your negative keyword strategy. Compare your cost per conversion and conversion rate before and after implementing comprehensive negatives. Many advertisers see 15-30% reductions in wasted spend once they've built out their negative keyword lists properly—that's budget you can reinvest in more profitable keywords or campaigns.

Make reviewing search terms a regular part of your Google Ads workflow, not something you do when you remember or when performance suddenly drops. Consistent, proactive negative keyword management keeps your campaigns lean and focused on searches that actually drive results.

Putting It All Together

Let's recap the complete process: Pull your Search Terms Report and identify searches that are costing you money without converting. Sort by cost and impressions to find the biggest offenders. Categorize your negative keywords by theme—job seekers, free/DIY, competitors, wrong products, informational queries—and choose appropriate match types for each. Create shared negative keyword lists in your Shared Library, one for each category, making them easy to manage and update. Apply these shared lists to all relevant campaigns at once using the "Apply to campaigns" feature. Add campaign-specific negatives where certain terms should only be blocked in particular campaigns, not account-wide. Set up a regular review schedule—weekly for high-spend accounts, bi-weekly for smaller budgets—to catch new irrelevant searches before they drain your budget.

Getting your negative keywords right across all campaigns is one of the highest-ROI optimizations you can make in Google Ads. You're not adding new capabilities or testing creative strategies—you're simply stopping yourself from paying for clicks that will never convert. The impact shows up immediately in your cost per conversion and overall campaign efficiency.

Start with your biggest cost-wasters—the terms that have already consumed significant budget. Build out your shared lists with those first, apply them across all campaigns, and you'll see immediate savings. Then expand your negative keyword strategy as you review search terms regularly and discover new patterns.

The beauty of shared lists is they make negative keyword management scalable. Whether you're running three campaigns or three hundred, the time investment stays roughly the same because you're updating centralized lists rather than individual campaigns. This is how agencies manage negative keywords across dozens of client accounts without drowning in repetitive work.
