Free Keyword Tool / Generator List

Top 5 Free Keyword Tool / Generator List

Anyone who is conducting keyword research on a regular basis needs to have access to tools that save time. Those who follow me will know that I have a specific view of tools -- they should only automate something you understand fully how to to manually -- and my reasons why.

(Hint: it's to do with tools being put beyond use.)

The following tools, by and large, are just time-savers. You can replicate their core functionality given a browser and some time, but they will make your life a lot easier!

This was among the first general-purpose auto-suggestion scrapers. It has retained its simplicity, and in the paid version, has added some search volume and CPC stats. Since these are available through other channels for free, I'm not sure how much value access to these numbers adds, but it certainly streamlines the keyword research process further. also works across sites -- Google, Yahoo, Amazon, etc. -- and has a useful 'question seeker' mode which often uncovers valuable problems, needs, wants and desires in niches.

Somehow, I've always found Ubersuggest's interface to be somewhat cumbersome, but you can't fault the results. 

It does the same thing that does, but returns more results and lets you see them as text, alphabetically, or as a word cloud. Whether these are useful to you will depend on your point of view.

The ability to expand keyword phrases from within the interface, as well as explore each one on Google, Trends, and so forth also add to the power (but also make it a bit distracting). Nonetheless, it stays on my bookmark list because for the few times I've wanted to fool around with a phrase for myself or a client, it has worked wonders!

(Just remember to stay focused, or you can get easily drawn into spending hours mixing up phrases!)

SEO Book Keyword List Generator

SEO Book's free keyword phrase generator is a bit daunting at first. But, ultimately, it is rewarding once you get what it's trying to achieve.

Firstly, it only works if you know what keywords you want to combine.

Given up to five lists of words, it will then combine them in each and every way, allowing you to then input the list into other tools to measure the anticipated effectiveness of the keywords.

It's one of those tools that you need to play around with before deciding whether it's right for you, but it's likely to find a place on your bookmark list because it's a quick and effective brainstorming tool.

SemRush works in one of two modes: you can give it an URL and it will extract the keywords and measure the SEO effectiveness of the site, but equally, you can give it a keyword phrase for a report on what the keyword landscape looks like for that phrase.

It can make for very interesting reading: from the number of searches, available results, and anticipated CPC figures through to lists of related keywords and phrase matches. Of course, the free version limits the quantity of these keywords returned, but it is great for a first look at a niche.

Personally, I recommend it as a tool that can be of great use early on, before a site is created and optimised, and then later on to track the performance of a site in search engine marketing terms. Agencies and keyword research professionals will probably find themselves able to justify buying a license for the expanded results, too.

Individuals, not so much, as a lot of mileage can be got out of the free version as long as you only have one project to evaluate.

Google Keyword Planner

There's always one that breaks the rules, and this is it.

The Keyword Planner does something that cannot be done elsewhere. It matches advertising needs with Google's search database. The result is that you can use it to generate alternative keyword phrases and get search volume and PPC stats by keyword phrase.

Not to mention, that if you have a collection of keywords generated by, say or the SEO Book generator, you can test them using the Keyword Planner.

The Google Keyword Planner is available, for free, to those with AdWords accounts (not necessarily  funded accounts at present.)

(Note: the reason it breaks the rules is that, if you base your entire keyword research philosophy on it's output, then if it is ever taken away, you will not be able to replicate your own results manually.)

Which is the Best Free Keyword Tool / Generator Combination?

Of the five three free keyword generators listed here, my preference is for simplicity; and that's why I regularly turn to However, if I'm working with a client who has a specific handle on their niche and keywords, then the SEO Book generator enables a list to be created based on combinations of sets of keywords.

It's a great time-saver if you already have the words, just want to know the best way to put them together!

Of the two evaluation tools, I personally use the Keyword Planner a lot. Probably more than I should, but then I'm also an AdWords and AdSense user.

What's great about SEM Rush is that it gives a great dashboard-style overview which can be replicated manually, and with more detail, using a combination of third party tools -- including the Keyword planner -- but is both prettier and more practical.

If you're a beginner, I'd use in conjunction with the Keyword Planner. But, the decision is yours!
