Manual measures are items that display penalty details.
This item shows the details of the penalty for manually suing the content that seems to have violated the guideline instead of the algorithm.
If you think your ranking has suddenly dropped and you’ve been penalized, check this page first.
Generally, if you receive a manual penalty, you need to improve what seems to have been pointed out and then undergo a re-examination (this is called a re-examination request). Upon receipt of this re-examination request, the manual countermeasure alert will be cancelled.
