Industry code for Internet Marketing?

I have 3 separate income sources (substantial). I'm confused which industry code will include all these 3: 

 

1. IT/Marketing Service revenue (the service I provide to my clients to build their websites and promote/market their companies online. I just get paid for my service, no commission)

2. Advertising Revenue: I sell banner ads on my website/blogs and earn revenue from it. For example, through google adsense.

3. Affiliate Commission Revenue: I market products from Product marketplaces (for instance Amazon) and when a sale is made, I get percentage commission from Amazon. I'm just using Amazon as an example here, the actual companies are different and they all have digital products (like ebooks) and I get commission when a sale is made through my online promotional efforts.

Please let me know if I have to add these as separate businesses or in just one. And what would the industry code?
