The importance of search engine optimization is no secret. Many people find websites through search engines these days, and it’s important to make sure your website is optimized for search engine algorithms. Google is probably the most important search engine you should care about, and they are constantly changing the algorithm they use to rank sites.
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.
