You can further refine this keyword list by adding more qualifying terms to the end of each base term, creating what are known as “long-tail keywords.” For example, if you wanted to reach people searching for “census data,” you could make that a more targeted search term by adding “1990” to form “1990 census data” or even more long-tail like “1990 Philadelphia census data.” Long-tail keywords are less competitive and have lower search volumes, which make them ideal for testing on smaller groups of customers.
