Well, if you create and manage your site for some time, then you will have the ability to make money with that. For example, Adsense or banners, or selling advertising space.... If you just redirect to merchant's sales page, you will only get commissions and that's it... So you should probably build your own site.
Then, that's not a site, but a landing page.... If you want to create A SITE, then it would focus on many different products in a specific niche..
I think you need to be clear about your intentions. I have some sites and I also have landing pages. One isn't any better than the other. Just decide what you want from it.
Develop your own domain - the long term potential is much better. I think redirecting is a short term strategy.
Develop your domain, but then create keyword specific redirects. Like domain/product and write reviews on your domain. I have one made for CB site that is running for almost 9 months now and makes sales as well as adsense earnings with natural SE traffic every month.
sorry i got mixed up,ok then let me rephrase it, if my intentions for my domain name is to be about one product is it better to develop a landing page for it, or should i redirect to my aff link. I do have plans for a site,but after my campaign with this specific domain name.
Go for landing page. If you can create a nice review, with pictures and good formatting, then in general, landing pages are better then simple redirect.
when you have a landing page you are also building the person up to buying a product. As they invest more in reading your review or whatever you have written, they become more convinced and when they do click are more likely to buy.
What are you wanting to do? Bum Marketing, PPC Marketing, SEO Marketing? With Bum Marketing, I wouldn't bother building up a website. With PPC, you are kind of forced to build the basics of a website if you don't want to get Google Slapped these days. With SEO, without a site you won't make any money
Develop your site. With SEO, and 1 year, you could easily be sending 500 hops a day to your publisher. If you convert 1:50 thats like 10 sales a day, just from free google traffic. Never forget that
