What is the average page number of an affiliate site?

Affiliate site ranking is pretty easy once you get the hang of it. You'll need to know basic SEO and put in a LOT of time. The number of pages depends on your site model, but ClickBank-type affiliate blogs do well with ~8 pages between 300-800 words each post.

mine are as big as i need them to be. i know this isnt the answer you wanted but theres no 1 number that fits all. one of my sites only has 2 pages while another has over 300, both of them make good money.

and its not about backlinks, its about traffic that converts.

Who knows? There are so many 1-page sites that I suspect the "average" is probably a much lower number than this, but it doesn't matter that much.

Across my entire range of niches, the correlation between "site size" and "income earned" is almost non-existent.

No, not at all.

It's "attracting search engine traffic" that's partly/largely about backlinks. Not the fact that it's an "affiliate site". The extent to which backlinks matter depends on whether you're trying to use Google as your primary traffic source, not on the fact that you happen to be an affiliate and that it's therefore an "affiliate site".

Business models that depend on this traffic can be very precarious, and ultimately they tend to put Google's algorithms in control of your business, rather than you yourself. As many Warriors discovered during 2011, some to their very great cost, a business model that depends on Google for its primary traffic is only one algorithm-change away from a major accident.

Be aware that even for those trying to build a business in this way, numbers of backlinks alone, and page ranks, contribute a lot less than they ever used to. What matter with backlinks, these days, are quality and relevance. (Other considerations matter only to people selling cheap mass backlinks.)

This. Exactly.

I do get 20% of my traffic from search engines, but it's significantly poorer-quality traffic, as one would expect: it leads on a pro rata basis to fewer conversions (opt-ins and sales).
