Improve readability: clearer texts, better use, more impact
Readability describes how easily a text can be captured and understood. Set structure, known terms and a clear outline help; font size, contrast and line length additionally influence the presentation.
Explain an action in an understandable way
From “The transmission of documents must be carried out before the deadline” becomes “Send us the documents by 15 November”. The second version specifies action, recipient and date. It's not just shorter, it's more accurate.
Check an important text with a person from the target group: after reading, can she say what to do, what requirements apply, and what happens next? This feedback is more meaningful than just reaching an index value.
What a Readability Index Can Measure
Flesch-based methods estimate linguistic complexity based on sentence length and syllable number. The formula used must fit the language. For German texts, the Amstad adaptation is often used: 180 minus average sentence length minus 58.5 times average number of syllables per word.
Such methods do not recognize professional correctness or a helpful structure. A necessary medical or legal term can deteriorate the numerical value and still be the most precise formulation. Explain technical words instead of removing them alone for a better score.
Check text and presentation separately
Short paragraphs and meaningful subheadings help to fly over. Use lists for real listings and tables for comparisons. A long specialist article needs recognizable answers, not a new subheading after each sentence.
In addition, check the text on a small screen and with enlarged font. Sufficient contrast, flexible line breaks and understandable link texts are not confirmed by a linguistic readability index.
Which statement makes sense for SEO
A certain readability value is not a proven ranking bonus. Even a long dwell time does not prove a good answer in itself: visitors can read for a long time because they lack the information they are looking for.
Therefore, evaluate a revision based on the task: Is a statement understood, a form filled out correctly or a suitable performance found? In the case of organic traffic, you can additionally observe comparable search queries and landing pages in the Search Console; this does not yet result in a clear cause-and-effect proof.
Practical issues
What readability value should my website achieve?
There is no universal target value. Language, target group and subject area influence the classification. Compare the same text before and after the revision and additionally check whether its statement is preserved.
Are short sentences always better?
No. Short sentences can help, but choppy or constantly repeated statements also make reading difficult. Crucial are clear references, an understandable line of thought and the appropriate accuracy.
