What are manual measures?
Manual measures have several functions. Among other things, Google carries out manual measures. This is the case when a webmaster engages in spam and should therefore be devalued. There is also the manual measures section in the Webmaster Tool. There, webmasters can see whether Google has taken action. It is also possible to react to this and have it checked again.
What significance do manual measures have for SEO?
If Google takes manual measures, this has negative consequences for the website operator. If the page is devalued and loses positions or is completely removed from the index, the page will not be successful.
It is very important for SEOs to be aware of the manual measures. This is the only way they can react in time and complain about a penalty. The Webmaster Tool makes it easy to react to a penalty. If an action is objected to, Google checks the page again and cancels the manual measures if it has proven to be incorrect.
A website is not simply penalized by Google. If spam measures or duplicate content have been identified, a devaluation is usually possible. Among other things, unnatural links, inferior content and misleading redirects also have a negative effect on the ranking.
