Negative Keywords: The List Every Calgary Business Needs

Quick Answer: Negative keywords prevent your Google Ads from showing on irrelevant searches that would waste budget. Every Calgary account should add a universal negative list (jobs, DIY, free, other cities, courses) on day one, plus industry-specific negatives, then maintain a weekly search terms review to add new negatives as Google triggers irrelevant queries. Most accounts have 100 to 500 negatives in a mature list.

Negative keywords are the most underused budget protection in Google Ads. Without them, your ads can show on queries that have your keyword in them but have completely wrong intent. A Calgary plumber bidding on "plumber Calgary" without negatives can pay for clicks on "plumber jobs Calgary," "plumber salary Calgary," "DIY plumber Calgary," and "plumber school Calgary." That's three to five clicks of wasted spend before noon on a typical day.

The math compounds. A typical Calgary service account collects 50 to 200 new search terms per week. Roughly 10% to 30% are irrelevant or low-intent on a typical account. At a $5 average CPC, an account collecting 100 new terms weekly with 20 irrelevant terms is wasting roughly $100 per week (assuming 1 click per term) or $5,200 per year. That's a real expense, completely preventable with weekly negative keyword management.

This guide covers the universal Calgary negative keyword list every account should apply from day one, how to build industry-specific negatives, how to manage negatives in shared lists across campaigns, and the weekly process for adding new negatives from search terms reports.

At a Glance

Quick Facts:

• Typical waste from missing negatives: 10% to 30% of clicks on a new account; 5% to 15% on a mature one

• Recommended weekly review: check search terms report every 7 days minimum

• Mature account negative list size: 100 to 500 negatives across account and campaign levels

• Match types for negatives: broad, phrase, exact (same as keywords; works in reverse)

• Recommended use of shared lists: apply universal negatives once across all campaigns

• -Most common missed negative: "free" (consistently triggers low-intent traffic)

What Are Negative Keywords and How Do They Work

Negative keywords tell Google not to show your ad for searches containing those terms. They work in reverse of regular keywords with the same three match types:

• Broad negative: ad won't show if all the words appear in the query in any order

• Phrase negative: ad won't show if the exact phrase appears in the query

• Exact negative: ad won't show only for the exact phrase, no variants

For most negatives, phrase match is the right default. Broad match negatives are powerful but can block more than intended. Exact match negatives are surgical but require listing many variants.

Negatives can be applied at three levels:

• Account level: affects all campaigns (use for universal negatives)

• Campaign level: affects only that campaign (use for campaign-specific negatives)

• Ad group level: affects only that ad group (rarely needed but useful for tight targeting)

Shared negative keyword lists (managed in Tools > Shared Library > Negative Keyword Lists) let you apply a list to multiple campaigns at once, which is the standard way to manage universal negatives across an account.

The Universal Negative List Every Calgary Account Should Apply

Apply these negatives at the account level from day one. They're irrelevant to almost every Calgary business and consistently waste budget when omitted.

Job-related negatives:

• jobs, careers, hiring, salary, employment, wage, salaries, openings, vacancies, recruiter, recruitment, resume, CV

Education and DIY negatives:

• DIY, "do it yourself", tutorial, course, courses, training, school, university, college, certification, certificate, class, classes, "how to", learn

• 
  

Free and cheap negatives (unless price is your differentiator):

• free, freebie, cheap, cheapest, discount, wholesale, bargain, "low cost", "lowest price"

Other location negatives:

• Edmonton, Vancouver, Toronto, Montreal, Ottawa, Winnipeg, Saskatoon, Regina, BC, Ontario, Quebec, USA, "near me" (if Calgary-only)

Information-only negatives (unless content marketing is the goal):

• definition, meaning, "what is", "how does", explained, examples, history, wiki, Wikipedia

Brand confusion negatives:

• Add competitor business names you don't want to spend money matching

That list alone often blocks 5% to 10% of wasted spend in the first 30 days of a new account. Apply it before launch, not after.

How to Build Industry-Specific Negatives

After universal negatives, every industry has its own irrelevant query patterns. Identifying them requires understanding your customer's actual search behaviour and what searches sound similar but mean something different.

Industry-specific negative examples:

Calgary law firm:

• "free legal advice," "legal aid Calgary," "law school," "lawyer salary," "Better Business Bureau lawyer," specific competitor names

Calgary roofing company:

• "roof rack," "roof access ladder," "roof gardening," "roofing supplies" (unless retail), "metal roof manufacturing"

Calgary dental clinic:

• "dental school," "dental assistant jobs," "dental insurance" (unless offered), "Alberta Health Services dental," "dental cleaning at home"

Calgary e-commerce (general):

• "wholesale," "manufacturer," "drop shipping," "Amazon," specific competitor stores, "returns policy" (unless returns content marketing)

Calgary B2B SaaS:

• "free template," "open source," "tutorial," "Excel alternative" (unless that's the positioning), specific direct competitors

Build the industry-specific list by spending 30 minutes brainstorming what your competitors' keywords would mean to someone NOT in your buyer persona. The non-buyer searches are usually the negatives.

The Weekly Search Terms Report Process

The Search Terms report (Keywords > Search Terms in Google Ads) shows the actual queries that triggered your ads. This is where most new negative keywords come from in a mature account.

The weekly review process:

1. Filter to the last 7 days of search terms

2. Sort by cost (descending) to see where money is going

3. Review each query for relevance to your business

4. For irrelevant queries: click the checkbox, click "Add as negative keyword," choose match type and level (usually phrase match at campaign level)

5. For relevant queries with deep impressions but no conversions: consider adding as new keywords in dedicated ad groups

6. Document patterns that emerge (multiple variants of similar irrelevant queries suggest a broader negative is needed)

A weekly 15 to 30 minute review of search terms is the single highest-ROI optimization activity in Google Ads management. Accounts that skip this step accumulate waste; accounts that do it weekly compound efficiency over time.

LTL Creative builds account-level negative lists for every Calgary client on day one and runs weekly search terms reviews as standard. Google Partner certification means negative keyword management follows current best practices, including using shared lists across campaigns and proper match type strategy.

Frequently Asked Questions

Can you have too many negative keywords?

Yes, but it's rare. The risk is over-blocking relevant searches by using broad match negatives too aggressively. The fix is to convert broad negatives to phrase or exact negatives and to review monthly which negatives are still preventing impressions on intended queries. Mature accounts with 200+ negatives running smoothly are normal.

Should brand terms ever be negative keywords?

Your own brand should never be a negative. Competitor brands are situational; some accounts block competitor brands from triggering generic campaigns (to avoid brand confusion). Most accounts run a separate competitor-targeting campaign instead and block those competitors from generic campaigns to keep the data clean.

Do negative keywords affect Quality Score?

Indirectly, yes. By preventing low-intent queries from triggering your ads, negatives improve click-through rate (since the impressions that do show are more relevant) and conversion rate. Both improvements feed into Quality Score over time. The Quality Score lift from a clean negative list is real but usually takes 30 to 60 days to fully show.

How often should I add new negative keywords?

Weekly is the right cadence for active accounts. New irrelevant queries appear constantly as Google's algorithm tests new search variations against your keywords. Skipping reviews for a month usually means letting $100 to $500 in irrelevant clicks slip through depending on account size. Monthly is the minimum acceptable cadence.

Do negative keyword lists work across Performance Max campaigns?

Performance Max accepts account-level negative keyword lists in 2026 (this was added in 2023; older guides may say otherwise). Apply your shared negative lists to PMax campaigns the same way you apply them to Search campaigns. PMax also has campaign-level negative keyword settings for additional control.
