I am in the process of completely re-vamping and redesigning a Feb '11 Pandalyzed ecommerce site that has a blog that is a mess. The blog has lots of thin posts, broken links, pagination problems, dupe content issues and other problems. But it also has a decent amount of original and good quality content written about the various products.
We're using new blog software with much better architecture on the new site so it will have a much better blog that we're starting from scratch.
I was thinking of adding the best 10-20 blog posts from the old blog to the new one. And then any good quality, original product-related posts that were left, I would add to the actual product pages themselves.
My thinking is that these left over ones are thin on their own, but would be a good addition to product pages that already have other, good content.
How do you think this will affect our Google rankings? Does it hurt you to take lots of your site's page content - and not do any 301ing for them - and moving them to other pages on the same domain? Anyone do this before without much of a problem?
