HOW TO TURN OFF BROAD MATCH KEYWORDS GOOGLE ADS

If you are searching for how to turn off broad match keywords in Google Ads, you are probably already suspicious that something is burning budget on searches unrelated to your product. That suspicion is almost always right. The case I want to walk through is an ecommerce account I took over in early 2025: broad match active across five campaigns, Target ROAS at 400%, eight months of history. On paper it looked reasonable. In practice, roughly 38% of ad spend was going to query categories that had never produced a single conversion.

The decision to turn off broad match keywords google ads-wide is never obvious in the moment, Google discourages it and the volume drop can look alarming. I want to show the full picture: what triggered the decision, the exact process, and what happened to ROAS afterward. I will also cover the google adwords keyword match type logic I use as a replacement, because turning off broad match without a plan for what fills the gap is how accounts lose coverage they actually needed.

What broad match was doing to this ecommerce account

The account sold premium kitchen equipment, stand mixers, chef knives, cookware sets. Average order value around €180, Target ROAS at 400%, actual ROAS at 310%. Nobody had reviewed the search terms in months. When I pulled 90 days of data sorted by cost, the top 200 queries by spend included "cooking classes near me," "kitchen interior design ideas," and searches tied to a popular cooking TV show. Zero conversions across all of them. Together, €9,000 in wasted spend. None blocked by negatives. The broad match type with Target ROAS is supposed to self-optimize, but the algorithm needs a clean conversion signal, and here it was being diluted by hundreds of non-converting queries it treated as meaningful data.

Two layers of broad match to address

There are two separate things to fix. First, the campaign-level broad match setting, which forces all keywords to use broad match regardless of syntax. According to Google's official documentation on the broad match campaign setting, enabling it converts all existing phrase and exact keywords to broad and ensures everything added afterward also becomes broad match, disable this first. Second, keywords entered as plain text without brackets or quotes, which is the default google adwords keyword match type Google assigns without explicit syntax. In this account the campaign-level setting was not even enabled: all the damage came from plain-text keywords entered from day one.

Before touching match types, I spent a week in the search terms report identifying what broad match was capturing that I wanted to keep: gift-intent queries, product comparisons, and brand-adjacent searches. I added those as explicit phrase match keywords first, then added 47 negatives in parallel. Broad match without maintained negatives is an open pipeline for irrelevant spend, understanding what negative keywords are makes that obvious. Plugging that gap before changing match types is a prerequisite, not an afterthought.

How to turn off broad match keywords in Google Ads: the exact steps

Both layers must be addressed to fully turn off broad match keywords google ads-wide.

Step 1: Disable the campaign-level setting

Go to Campaigns > Settings, select the campaign, scroll to the Broad match keywords dropdown and set it to "Off: Use keyword match types." Save and repeat for each campaign. This does not retroactively change existing keywords, it only stops the campaign from overriding new keyword syntax going forward. Google's documentation on keyword matching options explains exactly how each match type determines which user search query your ad is eligible to enter.

Step 2: Bulk-change keyword match types

Go to Keywords, filter by match type "Broad," select all, click Edit > Change match types > Change all match types, select your target type, and apply. Critical: do not edit keyword text in the same operation. Changing only the match type preserves the keyword's Quality Score history and performance data. Changing both at once creates a new keyword with no history, a real loss on a live account with conversion data behind it.

Step 3: Google Ads Editor for large volumes and first 48 hours

This account had over 800 broad match keywords across five campaigns, Google Ads Editor is the right tool at that scale. Filter by match type, select all, bulk-edit, export a backup first, then post and verify in the interface. Expect impressions to drop roughly 40% in the first two days. That is normal. Watch conversion rate rather than ROAS in week one: if it trends up, the how to turn off broad match keywords google ads change is working. If conversion rate also drops, something in keyword coverage was removed that should have been preserved.

What happened to ROAS: 60 days of real data

Impressions fell 38%. Clicks fell 22%. Spend dropped 28% on the same daily budget. Conversions in week one were flat, this worried the client. By day ten, conversion rate had climbed from 1.8% to 2.7%. ROAS moved from 310% to 360% in the first two weeks. Smart Bidding was already responding to cleaner signals.

Between days 15 and 45, ROAS was volatile, 340% to 420% week to week as Smart Bidding recalibrated. I kept Target ROAS unchanged and used this window to check keyword match type coverage for any missing clusters. By day 60, ROAS had stabilized at 435%, a 40% improvement over the 310% baseline. By day 75 it was at 450%, with conversion volume higher than the pre-switch period. The budget that had gone to cooking show queries was now going to "professional chef knife set" and "stand mixer 6 qt." For the auction prioritization rules that determine which match type wins, the guide on how match types work in Google Ads covers them in detail.

When I still keep broad match running

I do not recommend removing broad match unconditionally. When launching into a new product category without reliable keyword data, I sometimes run a short broad match discovery campaign with a hard daily cap and manual CPC, no Smart Bidding. The goal is intelligence: three to four weeks of search term data, then valuable clusters migrate to phrase or exact match in the main campaigns. After that, the discovery campaign is paused. This uses broad match intentionally with a defined exit point, the opposite of how it accumulates when nobody makes a deliberate choice about the google adwords keyword match type at setup.

On branded campaigns, broad match is less dangerous because the query pool is naturally bounded. Irrelevance risk is much lower than on category keywords, and the flexibility to capture natural language variations around the brand name is genuinely useful. For any other campaign keeping broad match, the negative keyword list must be reviewed against search terms data every two weeks, if that discipline is not going to be maintained, it is better to turn off broad match keywords google ads-wide. The review process I follow in every account is covered in the guide on negative keywords best practices.
