What is keyword research?

First thing first. Keyword research is a two-word phrase.

Keyword means the search terms people are searching for. The search queries are the various words and phrases that people types into a search engine search box. Search queries contain keywords. Let’s first discuss search queries and then talk about keywords.

Types of search queries

According to Pennsylvania State University, there are three types of search queries:

  • Navigational (Go)
  • Informational (Know)
  • Transactional (Do)


A navigational search query is known as a ‘Go‘ query. This is because this type of keywords is used for finding a particular website or webpage.

If you are in the SEO industry then you must know the brand Backlinko. When you enter the brand name in Google search box and hit search, then Google will pull that website and serve you.

This type of search queries is called navigational.


As the name suggests, informational search query includes the topics people are searching for finding answers. Hence it is also called the ‘Know‘ query.


You want answers to a question: “What are the features in new Google Search console?”

Doing research: “What is Google Rank Brain?”

Solve or fixing a problem: “How to install a theme in WordPress?”


A transactional search query is often used when people have the intention to make a purchase or any type of lead. These are called ‘Do‘ queries. Because this action is imminent. In marketing term, these are called buying intent.


Someone wants the Latest, Best, Fastest, Smallest: Best gaming phone under $700.

Compare A vs B: Nikon 80d vs Canon 700d

A Discount or Coupon code: PayTm first recharge coupon code.

Types of keywords

As of now, we have a clear idea about what is a keyword. So we can proceed further.

Based upon the length of the search term we may differentiate them into categories.

  • Short tail
  • Medium tail
  • Long tail

The term ‘long tail’ comes from the Ahref’s ‘search demand curve‘. This graph shows all keywords by their search volumes.

Short tail keywords: It usually consists of one or two words. For example, ‘keyword research’. These keywords are in huge search volume and a high competition.

Middle tail keywords: It usually consists of three or four words. For example, ‘keyword research tools’. These types of keywords are more specific and have less search volume. Sometimes this length also considered in the category of the long tail keyword.

Long tail keywords: It usually consists of four or more words. For example, ‘free keyword research tools’. These are most specific and detailed, but the search volume is the lowest among all.

Have you noticed something in this graph? The conversion rate increases as the ‘tail’ increases. Because “long tail keywords” have more chance of matching the searcher’s search query.

It is very easy to get and target “short tail keyword” as it has a high search volume. But you have to fight a battle against your strong competitors. What to waste time and money on that?

So as of now, we know that long tail keyword is best to use. Moreover, most of the long tail keywords are untapped.
