E-E-A-T itself is not a search ranking score. If you understand it as a way to increase your score by filling in the author introduction or the amount of structured data, you may miss the accuracy and reliability of the actual content.
Describe actual experience and verifiable evidence. Authors, reviewers, qualifications, and dates must be factual, and review of relevant areas is especially important for content that affects health or finances. You should not reinforce your credibility by creating examples or experts who do not exist.
Check whether readers can distinguish between claims and evidence and identify sources. There is no published universal formula for predicting that a specific profile or schema will increase AI citations by a certain percentage.
