does cj allows to build a stor for thier products with only thier links , and no other contents on the website
Your site is your site add content or don't, this is wonderful thing about this business, I have 3 different networks with different products from different stores all on one site with my original content and wording! Go FOR IT!!!!
For cj, it should not be a problem. Individual advertisers have their own rights to verify your site before being accepted, but most of them won't mind as long as you don't break any rules. Only people who wont like that kind of site is the actual visitors. So, if you are serious about making sales and getting traffic, you may have to rethink the strategy.
The most important factor is that there is nothing illegal in your site. Also, make your site professionally designed so as to enamor the advertisers when they review it.
