A great feature of this tool is that you can get autocomplete suggestions not only for Google, but also for YouTube, Bing, Amazon, eBay, Play Store, Instagram, and Twitter.

The drawback of this keyword tool is that you only get autocomplete suggestions and no related keywords. This means that every suggestion you get includes your search term. For proper keyword research, related keywords are essential, however, autocomplete suggestions are helpful for content creation ideas and title generation.

With the free version of Keyword Tool, you won’t get any search data. With the paid version you get search volume, search volume trends, CPC, and competition scores. The paid plan costs $199 per month.

Pricing: Free limited version, the paid plan is quite expensive.

Another great point about this keyword tool is that you get keyword suggestions not only for Google, but also for other search engines including YouTube, Amazon, Bing, Yandex, Naver, and Baidu. This is very helpful if you publish content on YouTube, sell products on Amazon, or if you’re targeting other search engines.

Ahrefs doesn’t have a free subscription, but you can get a 7-day trial for $7. Unfortunately, the keyword tool can’t be purchased separately, so you’d have to commit to Ahrefs as an overall SEO tool. The monthly pricing plans range from $99 to $999.
