Broad Match Isn't Evil. Your Negative Keyword List Is Just Lazy

Every six months the same debate resurfaces on marketing Twitter. Broad match is bad. Broad match is a Google money grab. Smart Bidding plus broad match is how agencies secretly steal from clients.

Some of that is true. Most of it is cope.

What Broad Match Actually Does

Broad match lets Google show your ad for searches that are related to your keyword, not just exact variations of it. Related is doing a lot of work in that sentence. In practice, related can mean anything from a close synonym to a query that shares two words with your keyword and nothing else.

If you bid on broad match for "project management software", Google will show your ad for everything from "asana alternatives" to "how to manage a project" to "free excel templates".

Some of these are great. Some are garbage. Without intervention, your budget goes to both.

Why People Blame Broad Match

Because when broad match fails, it fails loudly.

Cost goes up. Conversions do not. The Search Terms Report fills up with queries that make you wince. The easiest move is to blame the match type, pause everything, and switch to exact match.

It is easier than doing the actual work.

What The Actual Work Looks Like

Broad match without a proper negative keyword list is a disaster. Broad match with one is often the most efficient structure in the account.

Here is what a real negative list looks like after six months on an account running broad:

• 500 to 2000 negative keywords
• Campaign level negatives for category mismatches
• Account level negatives for obvious junk (careers, free, tutorials, DIY)
• Negative match types applied correctly, not everything set to broad negative by default
• Weekly additions based on the Search Terms Report

Most accounts have 20 negatives, all at the campaign level, all in broad match. Then the marketer complains that broad match does not work.

The Bidding Layer Matters Too

Broad match works when Smart Bidding has enough signal to decide which queries are worth pursuing. If your conversion data is weak (low volume, bad definitions, or missing offline imports), Smart Bidding is guessing. With broad match, guessing burns cash.

Fix the conversion data first. Then broad match starts behaving.

The Real Trade-Off

Exact match is safe. It is also self-limiting. You only reach queries you have already thought of. The keywords you do not know about are the ones your competitors are winning.

Broad match trades precision for reach. If you do the work (tight negatives, clean conversion data, weekly SQR review), you get both. If you do not do the work, you get neither.

Broad match did not waste your money. You did, by treating it like a set-and-forget tactic.

Open your negative keyword list. Count how many terms are in it. If the answer is under 100, that is your next task.
