Best Keyword Research Tools

Best Keyword Research Tools

Finding lucrative search terms is probably one of the best strategies to direct new customers to your website every day. The difficult thing is to find these search terms as well. We’ll introduce you to the best keyword tools that will certainly help you!

Every SEO – or anyone who wants to attract new visitors via Google & Co. – should first find the keywords that will later bring potential customers in search engine optimization.

Many companies invest a significant portion of their marketing budget each year in keyword research (then OnPage optimization and content production).

However, instead of just guessing which terms might provide a stream of willing visitors, you can follow the expert’s account and use professional keyword tools.

Many of them are paid for but often offer a trial phase or a reduced free version – some tools can be used for free but offer fewer features.

Let’s start with the Editors’ favorites:

The KWfinder of Mangools

The KWFinder is an excellent tool for search keywords because it makes the search for profitable search terms massively easier, offers interesting insights into the search results, and also looks great.

The KWfinder of Mangools

In contrast to the Google tool, the KWfinder displays the exact number of searches – even broken down into the last 12 months.

In this way, search trends can be identified and assumptions can be confirmed.

Especially the SEO difficulty feature has probably saved one or the other user a lot of time and budget because it shows exactly how difficult it is to rank for a search term.

This allows SEO beginners and freshly baked online retailers to focus on green search terms – SEO difficulty under 30.

Furthermore, the intuitive operation and amount of valuable data about the competition that the KWfinder issues are decisive factors that make it our clear favorite.

Of course, there’s a catch: it’s not the cheapest keyword tool.

The cheapest option costs you €29.90 per month (with an annual payment), but this is very cheap compared to other tools.

Also, you will receive not only the keyword tool for the prize but also three other great SEO tools, helpful instructions, and good support.

We don’t recommend using all of the tools listed above, but instead, stick to one or two and get used to them.

The Google Ads Keyword Planner

The Google Keyword Planner tool is one of the most used and popular keyword search tools.

The main reasons for the popularity of the Google tool are clear: It costs nothing and is integrated directly into Google Ads. To use this tool, you need a Google Ads account.

You can create an account for free, and you don’t need any money in Google Ads to access it.

Even if its previous version was much more extensive and showed the exact search volume*, you will get suggestions for new keywords here.

*For some time now, the exact keyword data has become invisible to AdWords users who spend little or no money on AdWords. Users now have to settle for approximate data (see screenshot).

The Google Ads Keyword Planner

It is one of the best free keyword tools.

However, if you need a more detailed and competitive analysis, WE would recommend you choose one of the professional tools.

Google Suggest

Google Suggest, also known as Autocomplete, provides search suggestions based on the first characters that were entered. This means you can use Google Suggest during a normal Google search.

Google Suggest

You can enter your product name and then type in different initial letters to see various suggestions for additions.

The Google Search Console

The Google Search Console (formerly Webmaster Tools) provides data about keywords for which your page already has impressions in Google Search.

This allows you to bet on combinations that you haven’t focused on before, but that is already relatively good.

Also, you can see here which CTR has been reached, i.e. whether your search result is actually clicked.

You can reach the report in the Search Console under Search Queries – Search Analysis. For example, you can filter by searches or pages and sort the key figures clicks, impressions, CTR, and location.

Pay special attention to keywords with high CTR, because your pages are perceived as particularly relevant for these searches. This is ultimately also a very positive signal for Google’s ranking.

Search Report Google AdWords

You can only evaluate this report if you have already shown ads on the search network.

Then you select and create corresponding search paths to be displayed with an ad.

However, various keyword options do not always trigger the ads only them.

You can directly analyze which terms have already achieved good performance without being booked directly. Use these keywords for organic search.

If you’re not putting ads on Google yet, you might want to consider it – after all, transactional searches now show up to four ads above the organic results.

Little-known Keyword Tool: Google Trends

Google Trends are used to assess current or seasonal topics in relevance. Enter your product terms in the search and determine if there are special peaks that are often searched for. Or can you see that there is much less search at certain times?

With this information, you can optimally plan your sales and optimization strategy. 

Google Trends

Also, the tool shows related search terms later, which you can also consider.

Tip: Use all of Google’s available data sources to learn more about your audience’s search behavior and terminology. There is no need to keep order, but rather you have to repeat some tools several times and vary the request.

Answer the Public – the visual alternative

An unusual tool because search queries are visual: Answer The Public. It collects and sorts search suggestions from the desired search term that you would get if you performed a normal Google search. The presentation is just a little different.

Answer the Public

As soon as you search for a keyword at Answer The Public, you’ll get a large number of questions, prepositions, and alphabetical lists for your request.

In this way, not only lucrative search terms but also tangible content ideas can be found and stored as lists.

Once you have keyword lists, you can research the search terms in detail in a professional tool such as the KWfinder, Google Keyword Planner, or an alternative tool.

Ahrefs. The all-rounder tool

Ahrefs can impress with a comprehensive range of social media and SEO tools that help you better understand your competitors’ content, as well as your own content while providing opportunities to find lucrative keywords.


Ahrefs is the basis of many SEO activities. Many SEO professionals and website operators use it every day to track website rankings, collect ideas for content, conduct keyword searches, monitor social media, and find new ways to get backlinks.

It is virtually the “Swiss pocket knife” of online marketing.

Likewise, Keyword Explorer has recently been restored from the ground up and is coming back bigger and faster than any other keyword research tool.

It’s definitely not cheap, with a minimum of $99 per month, but Ahrefs can replace several tools. A single subscription to Ahrefs can do the work of Google Tools, CWfinder, Ranking Trackers, and other keyword tools together.

However, the biggest advantage is also the biggest disadvantage.

Those who do not provide the whole day with the analysis and research will be absolutely killed by the infinite possibilities that the tool offers.

Even if only a fraction of the tool is used, the expensive monthly amount still has to be paid. If you only want to check or find search terms from time to time, you are much better off with our favorite. – The Google Keyword Planner Alternative is a free online tool that uses Google Autocomplete to generate hundreds of relevant longtail keywords on any topic.

The search terms suggested by Google Suggest are selected based on many different factors. One of these is how many times in the past, for example, users have searched for a specific search term.

The keyword tool can therefore make your research much easier by extracting Google suggestions, presenting them handsomely, and then making them available for download.

To generate long-tail keyword suggestions, adds different letters to the search term in fractions of a second and then displays them in a list. Within a few seconds, the tool can generate up to 750+ keywords from Google autocomplete.

Only in the paid version can all found search terms be displayed with data on search volume, cost-per-click, and strength of the competition.

After all, with the paid and free version of, you can quickly find, analyze and use thousands of relevant long-tail keywords for content creation, search engine optimization, pay-per-click advertising, or other marketing activities.

Keywords Everywhere – The Keyword Tool in the Browser

As the headline suggests, Keywords Everywhere is an extension for the Chrome and Firefox browsers.

It is free and works on Mac and Windows. Compared to the other keyword tools, the browser extension displays the search volume and CPCs when you enter terms in search engines like Google.

Keywords Everywhere

An impressive tool. Especially when you consider that it is free to use – you only need to request an API key (in exchange for the email address) to see search terms everywhere.

Can I Rank – The Allround SEO Tool

Can I Rank is a tool for smaller companies that provides not only data but also concrete recommendations.
