I want to start a affiliate marketing with certain product but I want to start with a free site like blogger or wordpress site. So is it a good decisions?
Go with wordpress, Have more number of features and plugins than google's blogger. And ofcourse its No. 1 too..
For affiliate marketing, wordpress has to be the choice but anyday if you want to try adsense. Just choose blogger. Google loves blogger.
I think better for you to use wordpress than blogger. But in my opinion, it is better if you use paid sites, because your site will look more professional.
Yes, it is possible to use a free website wordpress is definitely the way to go since this is also used in different web hosts, you can also use many plug-ins that would be useful for your site. However if you want to really earn with affiliate marketing, then I think you should buy your own domain and host to handle the kind of traffic that you are targetting to actually earn. This is just a small investment that will be well worth it in the long run.
That is how i got started was with a free site with wordpress and adsense. I have no become successful, it just takes some time.
Buy a domain for yourself and register with some free hosting site after that. There are a lot of sites around the web provides free hosting. 000webhost, zymic are among them. After that install wordpress in your hosting. Start posting and promoting your products there. You will get the maximum attention of your traffic. When you are promoting affiliate products through a free blog service provider like blogger, your visitor will not become interested at your affiliate products. This is a very natural approach towards a site by the traffic.
