Note: This post reviews web-based suggest keyword tools. It doesn’t cover desktop tools or plugins.

Whether your goal is to optimize content for search engines or getting fresh new content ideas, using the right keywords and phrases is a big factor of success.

The trick is knowing which keywords to incorporate in your content. If you’ve done a Google search for “keyword research”, then you probably know there are tons of methods, some using complicated classification tricks or simple keyword discovery tools. The most popular keyword tool by far is Keyword Planner. Conceived originally for Google Ads (formerly AdWords), this once external keyword tool is loved by SEOs for the metrics it provides. It’s biggest shortcoming? It mostly reveals only head or body keywords, and you have to wrestle it out of a Google Ads account.

But what about those times you need more detailed, long-tail keywords?

Google Suggest Reveals Long-Tail Keywords

Google Suggest is the “autocomplete” product that attempts to fill in your searches as you’re typing (through the Google suggestion box illustrated below). Have you noticed how detailed and long-tailed those suggestions usually are?  They’re based on real searches done through Google. Wouldn’t it be great if we could get those keywords into our spreadsheets?

Luckily, some smart developers created SEO keyword tools based on Google Suggest and APIs. Today I’ll share some of the best, free Google Suggest keyword tools that are out there.


I believe Übersuggest was the first keyword research tool for Google Suggest. At least it was the most popular. It was bought by Neil Patel, who changed the interface a bit.

The addition of search volume and CPC metrics are nice. The PD (paid difficulty) and SD (SEO difficulty) are interesting metrics. I’ve seen several tools try to formulate a similar number, but have never been one to trust in them too heavily. But for some who enjoy directional data, this may be for you.

Keywordtool.io Keyword Suggestion Tool

Next up is another great little Google keyword suggestion tool with a less-creative name. Called Keyword Tool, This tool is a lot like Like Übersuggest; it also takes your base term and appends it with letters and phrases.

Keyword Tool has more platforms to pull from. Instead of just Google, they have added support for YouTube, Bing, Amazon, Play Store, eBay, Instagram and Twitter.

The tool gives plenty for free, but will cost you if you need more keywords than the free version provides. Or metrics.

Answer The Public 

Answer The Public takes a cool spin on “suggest” data, targeted at finding and answering searched questions through Google and YouTube. Pick your subject (keyword) and pick your region.

Keyword Visualization


The results are solid (and similar to Keywordtool.io and Übersuggest). But this tool does something unique with visualizations.


Another awesome Google Suggest keyword tool is Keyword.io.

Keyword.io prepends and appends your search phrase with different letters from the alphabet as well as prepends your phrase with questions like “how”, “what”, “why”, and “where” to help you better meet searcher intentions. I like the option to pick keywords for exporting.

SEO Scout 

SEO Scout is one I just found. Much like the others with a good amount of options.

Which is the best?

To answer the question posed in the title, the best tool is… all of them. (I know, what a cop-out!) These are all very simple tools with a simple function. They all do the job of inspiring content ideas and optimizing copy. I have probably used keyword.io the most because I find the “pick and export” feature useful. My recommendation is to give them all a spin and see which you favor.

If you know of another Google suggest keyword tool that you’d like to share, let me know on Twitter.
