It is crucial as your conversion rates will be greatly improved and the products and services you offer will be bought at a higher rate as you will be receiving the right kind of customers. In addition, the constant traffic that is channeled to your website will have a great role to play in lifting the ranking of your website thus providing you greater visibility in Google searches.
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.
