The policy of cookies from Google Chrome has changed with its new version 80. This is a first step to definitively end the use and abuse of so-called cookies from third parties. These have an invasive effect on privacy that Google now wants to avoid without losing the advertising business.
Actually, when you visit a site that collects certain information about your visit, it is not a bad thing. It is even good because it improves your user experience by making it possible that, as the site knows your interests and preferences, the content it offers is more adjusted to your profile in the next visits. Thanks to these follow-ups, it is possible to offer those products that you are really looking for appear on your computer or smartphone or that the websites you have visited offer you the latest content of your interest.
The problem arises when this tracking crosses the borders of the sites that you have visited to be used by unauthorized third parties. That’s when you start receiving notifications, notifications and advertising from countless sites, and you wonder how a website you were not aware of knows so much about you.
What are cookies
The cookies are text files that are placed low on your computer or device when browsing a website. They are used to establish a profile of you and keep track of your journey through the site and your preferences.
Types of cookies
There are basically two types of cookies :
– On the one hand, we have same-site cookies used by the site you are visiting.
– On the other hand, we have cross-site cookies, which are those that come from sites that you are not visiting.
Through these last cookies, which are commonly known as third-party cookies, some domains access your browsing data without you knowing that they are doing so.
This is possible for two fundamental reasons:
The second is that these are mixed in not differentiating browsers and developers between several cookies and others.
Advantages and disadvantages of the changes
With the new objectives set by Chrome, the developers are obliged to define exactly the different types of cookies, tagging them appropriately. Google has thus passed the responsibility to these. Instead of banning third-party cookies outright, as Firefox and other browsers have done, you have chosen to limit the data they can access if their tags are not set correctly.
This can have several immediate effects:
– On the one hand, there will be sites that stop working correctly in your browser or, directly, do not work.
– On the other hand, it will affect SEO positioning and, above all, advertising and SEM.
However, it will strengthen your privacy as the developers have to secure HTTPS connections and differentiate between cross-site and same-site cookies in full transparency. In this way, the attacks that occur through access requests of false third-party cookies that until now could be presented as the site will be fully avoided.
One of the first effects that you will notice is that it will notably reduce the advertising that appeared by offering you the last thing you had searched for from a lot of e-commerce that you did not know. Now you will stop being informed of what interests you, but you will only find that information that really comes from your sites of interest and trust.
