**A mid-tail keyword** is a search term between broad short-tail and specific long-tail keywords. It usually has about two to four words and narrows a topic without describing a full need.

## How is mid-tail defined?
The category is a convention of SEO practice. Google does not define it, and sources draw the line differently, with word counts ranging from two to four. A useful reading is by effect. Short-tail terms name a topic, long-tail terms name a precise need, and mid-tail terms name a product type or subtopic. Smart Insights, an older article, groups search terms into head, mid-tail and long tail in a similar way.

Mid-tail terms commonly show moderate volume and moderate competition (assessment). Because the boundaries are fuzzy, it is more practical to check each term's actual search results than to sort it by word count.

## Example
“coffee machine” is a short-tail keyword, “coffee machine with grinder” a mid-tail keyword and “coffee machine with grinder under 300 euros” a long-tail keyword. The table compares these types with other keyword types and search intents. The examples are invented.

## Keyword types and search intents compared

| Type | Characteristic | Example | Category in Google's rater guidelines | Origin of the label |
|---|---|---|---|---|
| Short tail | short, broad term at the head of the demand curve; intent is often unclear | “coffee machine” | – | counterpart to the long tail; no clear first source |
| Mid tail | between the head and the long end of the curve; more specific than short tail, broader than long tail | “coffee machine with grinder” | – | no clear first source |
| Long tail | specific, rarely searched query, usually several words long | “coffee machine with grinder under 300 euros” | – | term from Chris Anderson, “The Long Tail”, Wired, October 2004 |
| Informational | find information on a topic | “how to descale a coffee machine” | Know, special case Know Simple | Broder 2002, “A taxonomy of web search” |
| Navigational | reach a specific website or page | “reddit login” | Website | Broder 2002, “A taxonomy of web search” |
| Transactional | perform an activity on the web, such as buying or downloading | “buy coffee machine” | Do | Broder 2002, “A taxonomy of web search” |
| Commercial investigation | consider a purchase and compare first | “best coffee machine” | no category of its own | industry usage; neither in Broder nor in the rater guidelines |
| Visit-in-person | go to a nearby place, such as a shop | “gas stations” | Visit-in-Person | Search Quality Rater Guidelines, section 12.7.4 |
