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.
Buying website traffic shouldn't be a replacement for SEO and other conventional methods of online marketing, but it can certainly give you that edge you need in the highly competitive online market. You can improve your Alexa ranking, time on site and lower bounce rate, but most importantly - it will drive potential clients and bring your website in front of your target audience long before you will see the first results of your conventional marketing strategies.
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.
