Not sure if the is the right place to ask, but I'll go for it. I have many Wordpress blogs and Squidoo lenses I use essentially as pre-sell or review sites for affiliate products.

Of course I offer bonuses to those who order through my links, and my bonuses are all ebooks I have written myself. What I have started doing is to say that if a visitor buys through a link, and sends me a Clickbank receipt, I will provide them with a download page within 24 hours for their choice of any one of 5-6 bonus items I show.

The bonuses are each pretty substantial, so I don't want to give them all away for any one purchase--and doing this I hope to have them come back and order other products to pick other bonuses.

Let's say on a particular Squidoo lens that 25% of my copy is related to my bonuses. What I want to do is to take my bonus section and copy and paste it into every lens I create to save time.

I've been doing this for years, but I still don't know about "duplicate content" but to my way of thinking I don't believe Google would see this 25% of my content on several lenses or blogs as something that would hurt rankings for the various lenses or blogs.

Do you think that's right--or should I vary the bonus section a little in each lens or blog that I use it on?

Thanks Much--Mike
