Sémantique et QBST : pourquoi mon contenu ne ranke pas ?

Semantics, the meaning of a word, is crucial for natural referencing. Google uses algorithms to understand the context of words, like "change," which can have multiple meanings depending on the surrounding text. This allows Google to evaluate the semantic relevance of search results. A "semantic field" refers to a single meaning of a word, while "semantic chants" encompass all the different meanings of a word. "Lexical fields" are all the words within a specific semantic field. For instance, the word "insurance" can have different semantic fields (e.g., a promise, self-confidence, or car insurance), each with its own lexical field (e.g., compensation, contract, claim for car insurance). To enhance a page's semantic relevance, it's essential to develop a coherent and consistent lexical field, avoiding repetitions and replacing irrelevant words with a rich vocabulary. Another key concept is QBST, or "salient words," which are the words Google expects to find when positioning a page for a specific keyword. Without these words, a page may not rank. Semantic analysis tools like Urtex Guru can help identify these statistically important words, which are difficult to discern manually. Other tools, such as Tot SO and Serpent, also offer optimization insights and scores, helping to avoid over-optimization, which can harm a text's ranking. Understanding lexical fields, semantic fields, and salient words, while being mindful of over-optimization, is vital for effective content creation.
