Most recently, I began to meet the opinions of people on various websites and forums that the online calculator is now a trend tool for Internet marketing. At various sites, and especially online stores and other e-commerce sites, where customers sell goods and services, you can often find built-in online calculators. Moreover, if forms are installed on the site, then these are not quite ordinary forms, but, as a rule, forms for calculating something. It became clear that entrepreneurs give preference to calculations, rather than simply to obtain customer contact information. If you start exploring further, the online calculator differs on sites, for example, there are sites where they use calculators created through the designer, for example, I often meet uCalc, there are sites where calculators are often installed via plug-ins, for example, Ez Form or Calculated Fields Form, the rest use more uncomfortable homemade calculators. It would seem that the tools for creating calculators are different, but all are actively used.
Why is the fashion for online calculators now and how does an online calculator as a whole help marketing?
