What are Long Tail Keywords for SEO and how to find them?

Long tail keywords are search terms with relatively low search volume and competition levels. Also, long tail terms tend to be longer in length (3+ words) than most other keyword types. Long tails are less competitive than shorter “head terms”. Mostly SEO used short keywords. Due to this it is easy to rank.
Here I am going to define some ways to find Long Tail Keywords.

1. Answer the Public: It is a helpful keyword research tool which generates question-Focused Keywords. In this tool you have option to put keywords and then click on Get Questions. Then the tool will show you questions that people tend to ask about your topic. Automatically you will get long tail keywords from questions. You have option to short them alphabetically. After that tool will allow you to download all keywords.
2. Google “Searches Related To…”: When you scroll to the bottom of Google’s search results there’s a section called, “Searches related to…”. This little area is a gold mine for long tail Keyword research. Take one of the keywords from the “Searches related to…” area and pop that term into Google. Then, check out the “Searches related to…” results for that keyword. Repeat until you have a massive list of awesome keywords.
3. “People also ask”section: This is the another way to find question keyword. First, search for a keyword in Google search. After that you will get the questions that people ask around the topic of the keyword you typed in. When you click one of the questions, you see an answer. Google will show you even more questions. 

Above are the some easy tricks to find the long tail keywords for SEO.
