5 Best Free Keyword Research Tool

Keyword plays a vital role to rank any article. Without proper keyword selection, it is next to impossible to be on the first page of Google Search.

You might have written a wonderful article on a keyword for which there is no search made by people. Then this is of no use as that article won’t get any traffic.

Unfortunately, many bloggers do not know how to do keyword research and there are hardly any free tools available in the market to do keyword research.

Most of the popular keyword research tools are paid and damn costly. But in this article, we will find out the 5 best free keyword research tools which may do the job that many popular paid tool does.

What Is A Keyword?

A keyword is a single word or a group of words people search for over the internet. For example, if we search for the word ” Cricket” then cricket is a single-word keyword.

But if we search ” How To Play Cricket” then it’s a multi-word keyword. We can search keywords and see how much the search volume and other parameters of that keyword are in keyword research tools.

Short tail Vs Long Tail keyword

A single or two-word keyword is considered a short-tail keyword. But if you use a multi-word search then it’s a long-tail keyword.

In the above example the word “Cricket” is a short-tail keyword but if you search for ” How to play cricket” then it’s a long-tail keyword.

Which Is Good: Short Tail Vs Long Tail keyword

Choosing between a short tail or a long tail depends on how your website stands on various parameters like domain authority and page authority etc.

If the blog is popular then even with a short tail keyword articles can be ranked. For beginners, it’s next to impossible to rank with a short-tail keyword because of huge competition.

In that scenario, beginners should start with long-tail keywords and once their blogs are popular they can try short-tail keywords.

5 Best Free Keyword Research Tools

We all know that powerful keyword research tools like Aherfs, Moz, and Semrush are all paid tools and the cost is extremely high.

For beginners spending $100 per month on a keyword research tool is a big pain.

Fortunately, we have a few free keyword research tool which is not as fancy as paid tools but does the job pretty well.

Google Keyword Planner

When we choose a keyword, we usually target google search to rank articles based on that keyword. Now that Google itself has a keyword research tool, nothing can be better than it. Right?

One of the best things about Google keyword planners is that it is easy to use. The user interface is very simple.

Google keyword planner was an independent tool before but now it comes integrated with Google Adwords.

In a nutshell, I would say it is the best tool for keyword research for beginners. But for Pro/Bloggers, paid tools yield more benefits.

Google Trend

Google trend is another powerful tool to search and check keyword search queries over a period of time.

It’s a comparative analysis tool to show how a particular search query performs over a period of time.
