In addition, we have a glossary that explains the most important terms regarding the content analysis.

Keyphrase-based assessments

  • Keyphrase in introduction
    Checks whether words from the keyphrase can be found in the first paragraph of the text.
  • Updated: Keyphrase length
    Checks whether the number of (content) words in the keyphrase is within the recommended limit. For languages with function word support only content words are considered. For languages without function word support all words are considered.
  • Updated: Keyphrase density
    Checks whether the (content) words from the keyphrase are used in the text and whether they are used often enough (but not too often). For a match to be found, all content words should occur in one sentence. Multiple occurrences of all content words within one sentence are considered multiple matches.
  • Keyphrase in meta description
    Checks whether all (content) words from the keyphrase are used in the metadescription. A match is counted if all words from the keyphrase appear in a sentence. Multiple matches per sentence are counted multiple times.
  • Updated: Keyphrase in subheadings
    Checks whether the subheadings reflect the topic of the copy (based on keyphrase or synonyms). A subheading is considered to reflect the topic if at least one (content) word from the keyphrase is used in it.
  • Link focus keyphrase
    Checks if there are links in the text, whose link text contains keyphrase.
  • Updated: Keyphrase in image alt attributes
    Checks if there are keyphrase or synonyms in the alt attributes of images.
  • Updated: Keyphrase in title
    Checks if the keyphrase is used in the page title.

    Checks if the keyphrase is used in the URL.
  • Previously used keyphrase
    Checks if the words from the keyphrase were previously used in a keyphrase for a different post.
  • Keyphrase distribution (only in Premium)
