As previously mentioned, web traffic can indicate the number of potential customers. The more customers, the bigger chance of conversions increase. E-commerce is a good example, as it is a sector that displays results in a form of specific transactions.
However, SEO/SEM activities on websites offering services are as important. Conversions do happen, but goals are defined differently. They can include visiting a contact information, submitting a form or downloading a file.
Blogs and news websites make a profit thanks to high traffic rates. They guarantee websites' popularity and revenue from adverts.
