Links to Sponsors

So in your blog posts, or your static pages, how many text links do you have, per page, going to the sponsor?

Do you put more on your static pages, or less than on your blog posts?

I know, links to the pics/vids would go to the sponsor, but how many text only links do you have per post/page?

Right now, I think I do about 4 per page, plus the graphic links.

Any SE downside to having too many, or not enough?

Your thoughts?
