I have recently added google authorship to my wordpress blog. When I search for specific posts on my blog, they come up with the post with my google+ picture and byline. On the other hand, when I search only for the title of my blog, I get my homepage (with google+ image and byline) and also a few post pages (this time without google+ picture, but with byline). The URL for these posts (with and without googe+ image) is exactly the same, and in any case I have already set my preferred canonical settings using my SEO plugin.
I think the problem is that my homepage shows recent posts (full excerpts), and then there is also my individual post pages with the same URL and same content. My guess is that the posts on my homepage are coming up in search results without the google+ picture (but with the author byline in search results). I am not sure how to resolve this issue, without changing the structure of my site. Any ideas?
