Best keyword research toolCompetitor researchOrganic and PPCHistorical data sets
Spyfu specializes in providing a database of keywords based not just on organic rankings but also of keywords used with Google Adwords. The result is the ability to track not just keywords but also keyword variations used by competitors, in both organic and paid search, allowing for a powerful analysis and keyword research platform.
The keyword research tool itself offers to provide deeper insights than Google’s own keyword suggestion tool, with the ability to not just track ranked keywords but also keywords used in PPC campaigns. This means you can source both sets of information for your own keyword research.
Even better is the ability to identify transactional keywords so you can focus on those keywords that convert traffic better, allowing for keyword quality rather than quantity. You can also distinguish between keywords used for both desktop and mobile devices.
While many SEO tools give preference to organic search, SpyFu provides a lot of PPC data to filter through, which makes it an ideal keyword research tool for both organic and PPC keyword research.
Although there’s no free trial available, Spyfu’s paid plans all offer unlimited keyword research volumes, with the only difference between paid plans dependent on the numbers of sales leads and domain contacts, top lists, and API rows returned. The cheapest plan costs $39 a month, or $33 a month with an annual subscription.

4. Google Trends
Best free keyword research toolFreeGoogle dataAPI
While Google does offer its own keywords suggestion tool for Google Ads PPC campaigns, perhaps it’s most valuable tool for keyword insights is Google Trends. This is especially as the internet is a constantly changing and developing medium, and identifying clear patterns in search behavior early enough could provide a long-term competitive advantage.
For example, a sudden rise in search traffic for a particular product or service might offer an opportunity to be targeted through a range of marketing channels, not just for SEO. This was the case during the corona virus pandemic when working from home led to an increase in a wide range of search terms relating to remote working software and work from home equipment such as laptops.
While that is an extreme example, even under normal conditions celebrity endorsements, new product releases, and changes to consumer behavior (often driven by new technologies) means that being able to identify such trends can be valuable.
Google Trends offers probably the biggest window on this, not just allowing users to search for specific keywords and identify the trends associated with them, but also by openly providing ongoing trends and highlights. This allows marketers to be able to tap into Google’s search data directly for key insights.
Best of all, like all of Google’s other SEO tools, Google Trends is free to use. However, the caveat here is that unlike paid-for tools, it means that you’re unlikely to be able to work with keywords by volume without being able to connect with the Google Trends API, which in itself adds development costs.

Best keyword suggestion toolStrong keyword toolMultiple featuresAffordable pricing
The Serpstat Keyword Research tool offers a great platform from which to cover a range of different keyword search and research options.
One feature includes the ability to do competitor research using URL analysis in order to identify keyword potentially missing from your campaigns. Additionally, you can use search questions in order to research specific keyword niches in order to identify further keywords and other ideas for driving targeted traffic to your website.
One of the more interesting options is the “tree-view” to see how keywords are distributed on your pages. While most might target specific keywords at a specific page, sometimes a different page might end up with better ranking potnential, such as by going viral. This tool aims to help you identify other useful pages which, if targeted instead, might improve your targeted ranking for those keywords.
Like other tools there’s also the option to search for related keywords, but on top of this there are a number of filters you can use to narrow your selections into the most useful keywords to target.
Plans start from just $69 per month for a single user, and that allows full access to Serpstat tools and data. Pricing is otherwise based on the number of users, so other payment plans are for when multiple users are required to access the account.
Overall, Serpstat offers a lot of interesting flexibility when it comes to keyword research, and the ability to use different tools and methodologies can only be empowering for website owners and SEO’s alike.
