What type of Traffic you need

You know that whenever you surf the net, you have something in your mind before you type any keywords in the browser for searching relevant websites. If you are obese and want to know the existing techniques to reduce obesity and weight, you will type the words like 'reduce obesity', 'lose weight', 'weight loss techniques' etc. Then you will find the websites on these subjects and you will search some of such websites to know further details. During the process you are likely to click some adsense ads or affiliate ads of your interest on obesity or weight loss . Since you are really curious to know about the techniques to reduce obesity and weight, you would actually devote your time to read the material and if you like some web content, you may also add it to your favourites or bookmarks, so as to study it again next time. If the sites offer selling some ebooks or material(affiliate sites), you could also purchase one of them. Thus you are defined as a targeted visitor. But if you are surfing the net and in the meanwhile some unrelated site suddenly pops up on the screen, it will be irritating to you and you are unlikely to study it further, unless the subject is of interest to you. For such sites, you will be an untargeted visitor. Now you know why it is always better to get a few targeted visitors rather than having a lot of untargeted visitors.
