3. <a href="https://soovle.com/">Soovle</a>: Keyword Research Tool (free)

From super expensive to free, we have Soovle—a completely free keyword research tool. 

This free SEO keyword research tool boasts a customizable engine. It suggests keywords from all the prominent providers in one place! Search engines like Google, Amazon, Bing, Youtube, and Yahoo are part of Soovle. It's fantastic when it comes to finding content creation inspiration.

With this free tool for keyword research, you can find unique untapped keywords. Also, you can use Soovle's notable drag and drop feature to save your favorite keyword ideas. Or, download your favorites to a CSV file and keep them close to your heart.

Now, we know that Soovle may not necessarily boast a fancy interface or a world of options. But, it really is one of the best free keyword research tools out there.

The several ways to play with Soovle:

You won’t find search volumes and you cannot scrape keywords by entering a domain name. Without estimating the traffic potential of a keyword, it is hard to use it for professional SEO. 

4. <a href="https://app.neilpatel.com/en/">Ubersuggest</a>

Ready for more free keyword search tools? Of course you are! Seriously, who doesn't love free stuff? Especially when it's from the SEO guru, Neil Patel.

Ubersuggest is more advanced than Soovle, but there is also one big catch—you are limited to 3 searches per day.

Ubersuggest is a tool that people love everywhere, and for good reason. Although many of its features are free to use, you can get a paid subscription to level up your SEO strategy. 

It offers search volume data, how your competitors are ranking, &nbsp;and keyword suggestions. Also, it provides you with an idea of how complex your keyword will be to rank, and so much more.

Ubersuggest also gives you a table of the top 100 Google results for a specific keyword. In this table, you'll find backlinks, a domain score, estimated visits, and a total number of social shares.

Under ''Content Ideas,'' you'll find content related to your keyword. You can see the estimated monthly visits and number of shares on Facebook or Pinterest.

Pretty cool, right? Let's check out the pricing.

5. <a href="https://ahrefs.com/">Ahrefs</a>

At number five, we have Ahrefs. This is one of the best keyword research tools, and is very similar to SEMrush in its features. But, it is even more expensive. With Ahrefs SEO keyword tool, you're able to come up with ideas by simply typing your keyword into the search box. Ahrefs will generate a bunch of ideas, not unlike other keyword research tools. 

However, there’s one thing about Ahrefs that really stands out. It's the question vs regular keywords. This useful feature helps you find matching terms. They can be questions that people would search for on Google. Or, you can generate regular keywords.

Keywords phrased as questions

In both examples, the keyword generated results come with:

Like many best keyword tools, Ahrefs also allows you to see keywords that your competitors rank for. By using their keyword analysis, you're able to match and target the exact keywords. 

It's clear that SEMrush and Ahrefs offer many other helpful tools. For instance, like finding broken link reports, and PPC keywords for Adwords. But nobody does it better than Seodity.
