Here is an overview of the most important updates.
A new core update from Google was released in mid-January 2020.
As was the case with last year's core updates, websites from the financial and health sectors were particularly affected.
They either gained a lot of visibility or lost some positions.
The trustworthiness of the domains was re-evaluated according to Sistrix.
Websites that were affected by the core updates from the past are very likely to be now.
However, the fluctuations in visibility seem to decrease with every update. However, the circle of domains affected is expanding.
Local Search Update November 2019
A new Google local search update was released in November 2019.
The new neural matching function is intended to help make search queries with a local reference even more interpretable.
The principle of neural matching also builds AI on artificial intelligence.
However, there is no need for action for local entrepreneurs.
The Bert Update, which was published in October 2019, is intended to ensure that complex search queries become even more precise and thus easier to interpret. As well as matching search results can be better adapted.
Above all, the context of the search query should be improved. It should also be interpreted less in individual words.
Basic updates and data refresh
Not all optimizations that Google makes are updates.
If you take a closer look at the topic of Google, you also come across the term data refresh. The difference is quickly explained.
An update is to be understood as a correct change to the Google algorithm.
An example of this is the introduction of the Penguin or Panda updates for the first time. These are quasi filters. These are placed over the algorithm. They relate to a specific area of the algorithm. This is determined by many different ranking factors.
However, these filters fundamentally need a database. They work on this.
If Google would like to improve a filter such as Penguin and, for example, would like to interpret the weighting of Penguin differently, only the database is updated for this purpose.
A so-called data refresh is therefore carried out. However, if Google wants to identify new signals and aspects, this type of improvement is an update. The latter have a significantly larger effect on websites and their ranking.
Core updates in 2019
There have been core updates fairly continuously in 2019. These took place in March, June and September. These have been confirmed by Google. The month of the release of the rectification is named.
What is particularly striking about these updates is that the affected pages have very clear and quick reminders. You can say that there are clear losers and winners of the updates.
Domains that felt the effects of the 2018 updates are now also affected by the updates.
It can also be seen that sites that showed a reaction to the March update also influenced the subsequent updates.
This can be clearly observed, for example, on the website Netdoktor.de.
The core update sense is to make the search results even more relevant for use and to optimize the performance while surfing.
