Keywords are a fundamental element of search marketing – the key terms and phrases that are used to anchor content and search queries.
Google doesn’t provide access to its Keyword Planner to anyone without an active Google Ads account, but there are plenty of other places to get keyword information from.
Here are 24 tools to find new keywords, keyword difficulty, and search volume.
Alongside Ahrefs’ backlink reporting and organic traffic dashboards, they have a really powerful keyword research tool.
Ahrefs’ paid tool provides keyword ideas as well as search volume for all match types.
It also has a keyword difficulty score metric which, in head to head testing, was slightly more accurate than other tools that offer a similar feature.

Its results return keyword ideas, estimated search volume, estimated CPC, keyword difficulty score, and current ranking domains.
Moz launched their own dedicated keyword explorer as a supplement to their SEO research suite.

Mostly known as a black hat SEO tool, Scrapebox has plenty of white hat uses too, including conducting keyword research.
With Scrapebox, a small handful of keywords can easily turn into hundreds and even thousands of possibilities.
A limitation is that Scrapebox is software that needs to run on a Windows desktop environment. The upside is that it’s a one-time purchase, versus a monthly or annual subscription.
Primarily a paid tool to help search marketers manage their pay-per-click campaigns, WordStream also has a free keyword tool that allows a limited number of searches.
Free results only include related keywords, but WordStream’s paid subscribers can see search volume, too.
Even for campaigns that focus on only Google, Bing’s keyword tool can still provide helpful insights on related keywords.
As Bing is itself a search engine, it gets data from much closer to the “source” than other keyword tools do.
This tool is free to use – you just need to have a website verified in Bing’s Webmaster Tools.
This is one of the oldest keyword tools in existence and they pull search data from the widest list of search resources.
It’s a paid tool, but you can conduct a limited amount of free searches.

These can then be filtered by a number of different metrics.
This is a paid tool, so you can only conduct a limited amount of searches for free.
This is my all-time favorite keyword research tool as it’s unique to your site and comes directly from Google.
Filter out branded keywords in your search console reporting and start looking for ideas that you can expand upon.
If you have too much data, you can use regular expression filters to find queries that fit within certain parameters like numbers of impressions, clicks or words.

20-24: Global Options
Additionally, if you are conducting SEO or SEM campaigns in places around the world where Google faces actual competition (e.g., Asia), you might be better off using keyword tools created for that local market.
The largest search engine in China has a free keyword tool that is part of its webmaster tools.
It also has a Google Trends-like product that gives hot trends and related keywords.
Another option is to use DragonMetrics for keyword research (paid tool with a free trial), which is like Ahrefs/SEMrush/Moz for Baidu.
Yahoo Japan & Yahoo Taiwan
These are the leading search engines in their respective markets and they each have their own keyword tools (behind login walls).
Their keyword data should be the same as what Google shows because they use Google’s organic results.
