What is Boolean Search?

SEO and Marketing Terms: Boolean Search

Boolean search uses logical operators such as AND, OR, and NOT to combine or exclude search terms. It helps narrow or broaden search results for more precise research.

How does Boolean search work?

In a search tool that supports these operators (such as Google or Bing):

• AND requires both terms. marketing AND analytics finds results containing both.
• OR allows alternatives. copywriter OR editor finds results containing either term or both.
• NOT excludes a term. marketing NOT jobs leaves out results containing “jobs.”

Some tools also support quotation marks to search for an exact phrase, such as "content marketing", and parentheses to group conditions, such as (copywriter OR editor) AND healthcare.

Where is it useful?

Marketers can use Boolean search to find research, potential customers, journalists, or relevant conversations. It’s also useful in recruiting and research databases.

What can go wrong?

The same search won’t necessarily work across different platforms. For example, LinkedIn supports NOT, while Google uses a minus sign directly before a word to exclude it, as in marketing -jobs.

Too many restrictions can hide useful results. Check the search tool’s instructions and simplify your search if the results become too narrow.
