The best place to hide a body? - Page 2 on Google!". In this popular joke among SEO managers, the punchline has a bit of truth in it. Nobody wants to end up on page two on Google or any other search engine, as less than 1% of all clicks occur on the second page of Google.

To rank on page one on Google, though, mountains have to be moved. If you know which ones, they quickly become like the light Styrofoam works from 5th grade. Advertisements at the very top of the search result is one option, using keywords in challenging content is another. Easier said than done: The right keywords are crucial. You can find these with good Keyword research tools.

But why do you need such software and is a keyword research really necessary? We answer these questions in this article. We also provide you with the four best free and six paid keyword research tools. With these, you can attack the top Search engine ranking positions on Google and Co.

Why should you do a keyword research and why do you need a keyword research tool?

Indirectly, we have already given the answer with the introduction. From a detailed point of view, keywords serve to be found in the mass of brands, websites and blogs by having Google play your websites as search results to users, increasing your website traffic.

Keywords are ultimately the terms that users enter into the search bar of search engines like Google. These keywords are divided into main keyword and secondary keywords. The main keyword gives the thematic focus of the respective website and the secondary keywords support this in content.

But it's unlikely you'll come up with all the keywords that relate to your topic and your target audience. Often, users search for other combinations in this context than you would do yourself. To discover new ideas for keywords, such keyword research tools are very useful and necessary. For they suggest to you the terms that users actually search for. With this list of suggestions, you can then delve deeper into keyword research and look for further keyword ideas.

In addition, keyword research is about much more:

  • Who and how big is the competition for a keyword?
  • How often is the keyword searched on Google per month?
  • What types of websites are usually displayed in the Google search results for the keyword?
  • How much website traffic can you expect from the respective keyword?
  • What related shorttail and longtail keywords are there?

A detailed Keyword analysis tells you exactly which keyword sets you should use for your project and which ones you should stay away from. This includes also questions, phrases and terms that consist of several words, but do not necessarily go together grammatically. If you don't do keyword research before setting up your website or your Content strategy, you're metaphorically just talking into the void. With a bit of luck, wandering users hit your article and thus your company. But this way is a waste of money and does not bring sustainable customers.

In short: A keyword analysis is an absolute must and keyword research tools help you to find and use the right search terms! With these relevant keywords you can then write your SEO texts.

We will show you now which ten keyword research tools are the best and clarify the frequently asked question of the advantages of paid versus free keyword tools. Unlike other software, there are actually significant differences here. Whether for free or for cash also depends a bit on how accurate your keyword analysis tool should be.
