I really agree with you on these methods to drive traffic without search engines. But one thing I had to mention that this kind of traffic will not be as targeted as organic traffic is. Thus,the conversion rate will be lower. Anyways great post. These methods are very helpful for new bloggers as driving organic traffic will be very difficult for them.
Whenever advertisers look for direct display ads or sponsored post ads on any blog or website they usually look for the metrics as those are the only signs via which one can get idea about the quality of website before even contacting with the owner. Getting targeted visitors via traffic generation tool will improve the rank and the rank will help you to get more advertisers who will pay you.
Web traffic is the amount of data sent and received by visitors to a website. This necessarily does not include the traffic generated by bots. Since the mid-1990s, web traffic has been the largest portion of Internet traffic.[1] This is determined by the number of visitors and the number of pages they visit. Sites monitor the incoming and outgoing traffic to see which parts or pages of their site are popular and if there are any apparent trends, such as one specific page being viewed mostly by people in a particular country. There are many ways to monitor this traffic and the gathered data is used to help structure sites, highlight security problems or indicate a potential lack of bandwidth.
