TIP: When Google does not announce an update and we find it as a major update then we call it a core update.

If you do not understand some of the terms which I’m going to mention, then don’t worry, because as I will explain these in more detail in our on-page SEO and technical SEO course.

So, in order to make sure that information is fully ethical and trustable Google introduced this search update. It validates the quality of the medical, law & educational websites by implementing something called EATMetrics stands for expertise, authority, and trust signals.

Google Search Penalty

So now let’s learn what is a Google search penalty. This important action you need to understand in an SEO industry when the website does not meet Google quality standards according to its algorithms or rules, Google will take either of two-step.

Automatic Penalty

One is known as an automatic penalty, where the search engine finds your site is not following the rules &without any human involvement at all using the automated search algorithms and negatively affect your website SERP ranking the page or remove the ability to rank top positions. It will lower your site SERPranking and to get your ranking back, you have to identify the errors, mistakes you have done and violations and fix them and continue to do SEO. Eventually, search engines will reverse the penalty.

Manual Penalty

This is more critical compared to automatic, where a person from search engine webspam team. visits your website and check whether you have abused SEO in any way and place manual penalties if they find any proof of it. It is generally hard to recover from this since this is a worst-case scenario, where you have to fix everything mentioned and most of the time the manual penalty will be placed due to a serious concern.

So, once you fix it, you need to send a request to the search engine so they can manually re-evaluate your site. The time it takes for fixing depends on the extent of damage which can range from just a couple of months, even up to years.

It is possible, but it will take a lot of time and effort to get back on track compared to an automatic penalty. It would be best if you kept in mind that any SEO work you do has both positive and negative effects. However, even if your website is fully optimized for all the current SEO algorithms. Now, that does not mean it will protect itself from future algorithms also.
