Who Should Use Keyword Research Tools?

Keyword research has long been a key aspect of any effective content marketing strategy (although keyword stuffing should be avoided), and is the backbone of new content pillars and topical authority.

Using keyword research tools like Keyword Tool is brilliant for brainstorming new content ideas and concepts that also match your audience's search intent

You need to ensure that the content you’re creating is what your audience wants to see. That’s where a keyword tool comes in.

They’re excellent for content marketing managers, small businesses, and even freelance content consultants who offer SEO as a service.

What are the pros of using a tool for keyword research?

As mentioned, keyword research tools are fantastic for understanding what your target audience is searching online, allowing you to write content that keeps them engaged.

Creating great SEO-friendly content is not an easy process. After all, you’ve got to make sure it’s high-quality, unique, offers great insights, and meets all of the algorithm requirements. 

So, you want to make sure that your audience wants to see what you’re creating, and that there isn’t too much competition in that area.

How much does Keyword Tool cost?

Keyword Tool is completely free to use with no paid plans, but there is a catch. 

To access any of the important information, you need a Keywords Everywhere API key (see screenshots below).

How to Use Keyword Tool: A Quick Overview

To use the tool, all you have to do is enter your keywords into the search bar. You can enter as many as 10 or as few as 1 before hitting the magnifying glass to generate your results.

Here’s an example below from our search of ‘content marketing’:

You can then use the advanced filter to filter your results further if needed, before getting your final list of potential content ideas to work through.

As you’ll notice from the screenshot above, though, you can only get access to the monthly volume and traffic trends by putting in an API key.  

So, while you can input a search into the tool, if you want to see the results, you’ll need an API key.

Keyword Tool Features to Note

The Keyword research tool is the primary tool offered by the Keyword Tool platform, although you do need an API key to view results.

Within the tool, you can change the location you're targeting for more localized results, and also move from Google keyword research to YouTube and Amazon as well, which is helpful if you’re looking to create copy for those platforms.

KeywordTool.net: Final Thoughts

Overall, the concept of having a free keyword research tool can be very appealing, but the particular offering of KeywordTool.net may not be suitable for everyone, especially considering that an API key is required to view the results of the keyword research. Further, it doesn’t offer several of the most important content marketing support tools that are essential in 2025.

Frequently Asked Questions

Do I have to fill out the entire form?

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

In The Press

Originality.ai has been featured for its accurate ability to detect GPT-3, Chat GPT and GPT-4 generated content. See some of the coverage below…

Originality.ai did a fantastic job on all three prompts, precisely detecting them as AI-written. Additionally, after I checked with actual human-written textual content, it did determine it as 100% human-generated, which is important.

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.

How Can I Conduct a Plagiarism Check between Two Documents Online?

With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.

What Are the Benefits of Using a Text Compare Tool?

Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.

What Files Can You Inspect with This Text Compare Tool?

We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.

Will My Data Be Shared?

There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.
