Broad Match Modifier: Examples and Tips for SEO Success

What was broad match modifier?

Broad match modifier (BMM) was a Google Ads keyword match type that let you pin specific words as required using a plus sign — +running +shoes — while allowing the rest of the query to vary in order and wording. It sat between loose broad match and rigid phrase match: your ad could show for many variations, but only if every “plus” term (or a close variant) appeared in the search.

In February 2021 Google began retiring BMM and folded its behavior into phrase match. By July 2021 you could no longer create new BMM keywords, and existing ones now behave like phrase match. So while you’ll still find BMM guides across the web, the match type itself is gone — what remains is the discipline it taught.

Why it still matters for search strategy

The reason marketers obsessed over BMM wasn’t the syntax — it was control over which searches trigger spend. That problem never left. Every wasted impression on an off-intent query drains budget and pollutes performance data. Roughly a quarter of paid budgets still leak on queries that were never going to convert. Whether you’re running ads or building an organic keyword map, the core skill is the same: identify the words that must be present for a searcher to be worth your attention, and systematically exclude the rest.

Here’s how the same seed behaved across match types, then and now:

Notice how BMM and modern phrase match overlap heavily — that’s by design. The word order flexes, but your required terms anchor the intent.

Tips for controlling reach today

• Lead with phrase match for new campaigns. It inherits BMM’s flexibility while respecting meaning and word context.
• Reserve exact match for proven converters. Once a query reliably produces pipeline, isolate it in exact match with its own bid.
• Build negatives before you build reach. A tight negative-keyword list is the single biggest driver of efficient spend — add terms like “free,” “jobs,” or “course” when they don’t fit your ICP.
• Cluster keywords by intent, not volume. Group must-have terms the way BMM forced you to, then map each cluster to a dedicated landing page.
• Review the search-terms report weekly. Actual queries — not your keywords — tell you what to add as negatives or promote to exact.

From match types to organic strategy

The habit BMM instilled — pinning required terms to intent — is exactly how strong SEO keyword clustering works. When you group queries by the words that must be present, you learn which pages to build and how to structure them so both searchers and AI answer engines understand your relevance. Feed those converting queries into your CRM so paid and organic learnings compound, and put your reach controls to the test with a free audit of where budget and rankings currently leak.
