These are very useful tools to evaluate the pros and cons of numerous types of services such as telephony, gas and electricity operators, airlines, insurance companies, hotels and much more. They are nothing more than sites that aggregate the data of individual operators, proposing the best solutions based on a series of parameters often customizable down to the smallest detail.
On the web there are now many comparison sites. Some specialize in one or two sectors, while others, like Idealo.it, range in a rather transversal way from flights to hotels, passing through magazines and shopping. The ultimate goal is always the same: to save not only time, but also (and perhaps above all) money.
Among the most popular comparison sites there are those that compare the prices of consumer goods, allowing you to analyze the prices of millions of products of any product category for free. The most famous are, in addition to Idealo, Find prices, Lastminute is ShopAlike.
A phenomenon, that of comparison sites, born in the United States of America in the early years of the new millennium, which then spread rapidly from the beginning to the other English-speaking countries (in Europe, the United Kingdom above all), and immediately after a while in the rest of the world.
Today it is more difficult to find a category that does not have its own comparison site than the opposite. Even in the online gaming sector there are sites that offer this kind of service, able to compare online casinos like Betnero to the many other competitors on the web.
The advent of the comparators has brought undoubted benefits to the end consumer, also pushing the companies themselves to lower prices, in order not to lose an important part of the customers. Sometimes technology ends up harming the human being, but in this case the implications are only positive.
