How many Affiliate Links do I put in one page?

[kingp]

Too many for what exactly? Are you trying to rank your website in organic search? If so you need to understand each link you add detracts from the overall link value of your page.

Too many for users? Begin by using your best judgement and perform A/B testing.

In short, if you configure your site to provide the most authentic value for users and you succeed, Google will not have any problem with your site. If you attempt to manipulate your users or Google, then you are risking a penalty.

I don't think that the OP has asked this about for any Google Penalty. I think that OP has asked for user experience.

And yeah. Maximum two links per page is the best option.
