* **Over-optimization:** A high frequency of a keyword might indicate "keyword stuffing," which can negatively impact SEO. The threshold helps identify potential issues.

What is the Word Frequency Analyzer?

This tool is a special helper that looks at your writing and tells you which words and phrases you used most often. It’s like a smart counter that not only counts your words but also helps you make sure you are using them in a good way for SEO. This is a great seo keyword checker for any kind of content.

Why Use This Tool?

Improve Your Website’s SEO: Search engines need to know what your content is about. This tool helps you make sure your main keywords are used, but not too much.
Avoid Keyword Stuffing: Keyword stuffing is when you use a keyword too many times. This is a bad practice and can hurt your SEO. This tool helps you find overused keywords so you can fix them.
Find Related Keywords: The tool gives you suggestions for related words. Using these words helps search engines get a better idea of what your content is about and makes your writing more interesting.
It’s Free and Private: This tool is free to use, and your text is never uploaded to our server. This makes it a very safe and private way to work.

How Our Word Frequency Analyzer Works:

This tool works by simply counting words and phrases and comparing them to a rule you set. Here is a simple look at how it works:

You Paste Your Text: You type or paste your words into the box.
The Tool Cleans the Text: The tool quickly changes all the words to lowercase and removes punctuation. It also has a button to ignore common words like “the,” “is,” and “and.”
It Counts Everything: The tool then goes through all the remaining words and counts the frequency of 1-word (unigrams), 2-word (bigrams), and 3-word (trigrams) phrases.
It Finds Over-optimization: You can set a percentage threshold with a slider. If a keyword’s frequency is higher than that percentage, the tool will mark it as “over-optimized” to show you that you may have used it too many times.
It Gives LSI Suggestions: The tool looks at your top keywords. It then checks a small, built-in dictionary for related words and gives you suggestions for them.

What is the Logic Used in This Tool?

This tool uses simple logic built into your web browser. There are no complex math formulas or advanced AI.

N-gram Generation: The tool simply goes through your text and makes a list of every single word, every two words in a row, and every three words in a row.
Over-optimization Check: The tool calculates a percentage for each keyword (how many times it was used compared to the total number of words). It then compares that number to a number that you, the user, set.
LSI Suggestions: This is not a real “LSI keyword finder.” The tool has a small list of common words and their synonyms built-in. It simply checks your top keywords against this list and gives you suggestions. If it can’t find a match, it gives you a general tip.

How can a simple tool provide "LSI keyword suggestions"?

This tool uses a simplified, rule-based system. It is not an advanced AI tool that understands context. It simply checks your top keywords against a small list of related words.
