Are you allowed to place affilliate links on your blog in order to promote affiliate products. If so, how many are allowed.
Will my blog be regarded as spam when iI want to simply promote my affiliate products?
Advertising is, except for a couple very narrow exceptions, not allowed on wordpress.COM. For the exceptions, see the last sentence under “Affiliate marketing blogs” in the bottom set of bullet points in the “types of blogs” link below.
If they are projects that you have actually created yourself, such as jewelery, pottery or perhaps painting or crafts that are sold somewhere then wordpress has said those are OK. What you need to do though is to contact them and discuss it with them and if possible have links to some of those products.
