Are you looking for free keyword research tools that can perfectly fit your requirements?

I’m sure you will like the collection of some of the best hand-picked free keyword research tools.

Keyword research is the most essential part of SEO (Search Engine Optimization).

It helps you to find the words or terms that people actually enter in search engines like Google to search for their interests.

Not only that, but it also helps you to find the search volume of a specific keyword, difficulty, trend, cost per click, etc.

Sometimes it becomes tough for you to go for a paid keyword research tool (especially if you have just started) because they used to be very high in price.

You can’t spend all your money only on keyword research tools because you also need to take care of the essential expenses of your website which you can’t stop.

Such as your hosting, domain, and other tools charges (depends on your need).

To help you out with this problem, I have decided to make a collection of free keyword research tools that I have already tested.

Some tools are entirely free, and some are free with limitations, but don’t worry; you can still take much out of them.

Exploring these tools, you may find two or more tools having completely different features to each other.

So at some point, you may need to use them together to get perfect complete data.

Yes, that’s a little lengthy process, but for now, it is all about how you can take benefits from their free features at your best level.

I do the same, which you can too.

Let’s dive into our first free keyword research tool. 😀

1. SEMrush
