How long do articles live on articles?

Question

Web traffic analysis

All health. There was an idea to create an article on the topic of assistance in choosing a product such as Expertzen, Brand Quality, etc.
But the thought comes to mind that such articles do not live long, because. new goods are constantly being released and articles on old ones will not be needed. Let's say the rating of phones in 2019. By the way, I noticed that someone calls the ratings without reference to a specific year, apparently for the same reason? If we take topics such as culinary or psychology, then in my opinion the article can live there for a long time, if not "forever". Experienced tell me, am I right in my doubts?

Answer 1

This is because you cannot know anything about the nature of the goods. Therefore, you can only write superficial articles. There are a lot of products, you will not be able to try them all. To write a good article, you need to specialize in a certain group of products.
As an opposite, solid articles by people who really know what they are writing about live for years . Well, as an example, the Sportsmarathon blog.
