Did you know that 20% of the queries Google receives each day are ones, we haven’t seen in at least 90 days, if at all? With that kind of unpredictable search behavior, it’s extremely difficult to create a keyword list that covers all relevant queries using only exact match, Amanda Kelly.
Broad match is a great way to capitalize on those unexpected, but relevant queries. When you include a keyword as a broad match, your corresponding ad is not only eligible to appear alongside queries with that exact spelling, but it can also capture keyword expansions that include synonyms, singular/plural forms, relevant variants of your keywords, and phrases containing your keywords.
To make the most of broad match, you can run search query reports to monitor your expansions. If you discover a query that’s performing exceptionally well, consider adding it to your ad group as a broad match keyword and setting an appropriate bid. Conversely, if you see that one of your keywords has been matched to a search query that doesn’t fit with your campaign, include that search query as a negative keyword in the appropriate campaign or ad group.
