Long-tail keywords are highly specific search queries that tend to have relatively low search volumes.
Although users search for them less often, long-tail keywords make up a large percentage of overall searches when added together.
The phrase “long tail” was originally used to describe the phenomenon that niche products on sites like Amazon tended to account for more total sales than the top bestsellers.
As it turns out, the same thing occurs with keywords that people type into search engines.
In fact, the term “long tail” refers to the “tail” at the end of a curve.
