I've got previews of my books on my website, pretty much the same as you'd see on Amazon or other sites, but in downloadable .pdf format. However, I'm starting to think this is a bad idea, rather send the reader straight to the buying sites, they can check the preview there - Once there (Amazon or other store), they will find it easier to buy, whereas downloading a partial .pdf of my book from my website might lose them (even though, at the end of the .pdf, I do have a link to where to buy the whole book).
What do you guys n girls think, should I leave the previews on my website or remove them?

You're right that this sounds a bit cumbersome. Especially as PDFs don't have all the neat aspects of a dedicated e-book file.

Personally, I'd have a "sample" page with a full prologue (or chapter, if your book has no prologue) and buy links at the end. This may be shorter than the sample but manageable for someone who just came across your site.

Might be worth setting up some analytics on your site, like the Google ones.

That will give you information to go on about visitors - how many click on what, and also if they hit the link to go on to Amazon or wherever.

Without some numbers, you're just trying to guess what people are doing on your site.
