Introduction
Keyword coverage helps you understand how well your content is optimized for defined SEO keywords. In contentbird, the system analyzes how often and in what form your performance keywords appear in the text – providing an important foundation for data-driven content optimization.
Explanation of the Feature
Keyword coverage measures how often your defined keywords are used within a piece of content. The system distinguishes between two types of coverage:
Exact Coverage
A keyword is used in the exact form defined.
Example:
Keyword: “Content Marketing”
In the text: “Content Marketing” → counted as exact coverage
Extended Coverage
The system also recognizes slight variations of the original keyword. This is based on the so-called Levenshtein distance algorithm.
Words with a maximum difference of three characters are still considered equivalent
This includes inflections, plural forms, or minor spelling variations
Example:
Keyword: “Marketing strategy”
In the text: “Marketing strategies” → counted as extended coverage
Limitations of the Analysis
Not all variations are detected. Especially with more complex keywords, there are some limitations:
Long-tail keywords are not recognized if they are modified within the text
Additional words within a keyword will prevent it from being counted as coverage
Example:
Keyword: “Merlot south-facing slope”
In the text: “Merlot from the south-facing slope” → not counted as extended coverage
