Text Analysis
Readability Analysis

The spellcheck24.net readability index is a value between 0 and 100. The higher the value, the easier the text is to understand. Well-understandable texts have a value of about 60 to 70.

Word Density Analysis

Texts written about a specific topic should preferably contain the keywords. On the other hand, annoying word repetitions can also occur.

Filler Word Analysis

In general, it is advisable to avoid using filler words. However, the use of a few filler words - especially in longer texts - can improve text flow.
