# Blog Text Analysis: Configuration, Logic, and Difficulty Levels Explained

Text analysis in the olaao system is designed to help content creators better understand how readable and demanding their blog articles are. Instead of a subjective estimate, the system evaluates each article using measurable linguistic factors such as sentence length, word complexity, and estimated reading time. This approach ensures consistent content quality while allowing authors to tailor the difficulty level to the target audience. At the same time, thanks to text analysis, each visitor can estimate in advance how demanding the reading will be.

How text analysis works

When a blog post is saved or updated, the text analysis engine processes the content in its clean, readable form. All HTML tags are removed before analysis so that only the truly visible text is evaluated. The system then counts the total number of words and sentences, calculates the average sentence length, identifies complex words based on their length, and estimates reading time according to the configured reading speed.

The difficulty level is then calculated by comparing these values with predefined thresholds. Longer sentences and a higher proportion of complex words increase the resulting text difficulty. This approach ensures that the difficulty rating reflects actual reading effort, not merely the author’s stylistic preferences.

Key configuration parameters

# Reading speed (words per minute)

Defines how fast an average reader is expected to read the text. This value is used exclusively to calculate the estimated reading time and has no direct impact on the resulting difficulty level.

Default value: 200

# Minimum word count for analysis

Defines the minimum length of text from which difficulty is evaluated. Shorter texts below this threshold are always classified as very easy.

Default value: 30

# Minimum length of a long word

Defines how many characters a word must contain to be considered complex. This parameter allows adaptation to different languages and writing styles.

Default value: 7

Difficulty level logic

Difficulty levels range from Very easy (1) to Very hard (5).

Each level is defined by two conditions:

- average sentence length

- percentage of long words

If at least one of these values is exceeded, the text is assigned to the corresponding difficulty level. This two-condition logic ensures a balanced, realistic, and consistent evaluation of readability.

Enabling and disabling text analysis

In the section Blog → Settings → General → Difficulty, you can decide whether the difficulty analysis of your articles should be displayed to visitors. olaao automatically analyzes the text of each article in the background, and you only decide whether the calculated value is displayed or not.

User-defined analysis settings

Each user can define their own text analysis rules in the section Blog → Settings → Difficulty. All parameters can be adjusted to match the target audience, industry standards, or a personal writing style. Educational content, technical documentation, and marketing articles can therefore use different threshold values without any impact on system performance.

Manual difficulty setting per article

In addition to automatic analysis, olaao allows authors to manually set the difficulty level for individual blog posts. If this value is set, it automatically overrides the difficulty calculated by the system. This option is suitable, for example, for opinion pieces, narrative content, or specialized texts where perceived difficulty does not correspond purely to linguistic complexity. The difficulty level can be set directly in the administration of the specific article.

Recommended practices

It is recommended to start with the default analysis values and adjust the parameters gradually. Configuration changes should be tested on existing articles and you should observe how their difficulty classification changes. Avoid extreme values so that the rating remains consistently meaningful over time across all content.

By combining automatic text analysis, user configuration, and the option of manual override, olaao provides a transparent, flexible, and professional system for managing blog content readability. As a result, your content remains structured, clear, and aligned with readers’ expectations.
