The truth is, dear reader, that content overrules everything. You cannot make a success of a site unless you have the valued content there to begin with, as a foundation for your work. If that content is not there, nothing will come of it. If it is there and it’s valuable, the rest will pretty much take care of itself (aside from the physical aspect of site performance).
Not all web traffic is welcomed. Some companies offer advertising schemes that, in return for increased web traffic (visitors), pay for screen space on the site. There is also "fake traffic", which is bot traffic generated by a third party. This type of traffic can damage a website's reputation, its visibility on Google, and overall domain authority.
