Note: There are literally dozens of places you can use a keyphrase, from captions to comments, web addresses to “Alt” tags. Feel free to get tricky if you’d like. But generally, the less visible it is to readers, the less important it is to Google. So focus on those elements listed above. That’s what readers (and therefore Google) really care about.
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.
