SEO issue: titles, permalinks and canonicity

Hi,

My website (which I’m currently preparing to migrate to WordPress) has a lot of lengthy multi-page articles, but existing users have been asking for an option to view an article as a single page. I was hoping PLP might be a good solution to that, but I’m concerned about its SEO impact.

Here’s the dilemma. The single page view inherits the same header data as the first page of the paginated article. If the single page view has the same title, meta description, and some of the same text as page 1 of the paginated version, I’m very concerned that search engine robots are going to see the single page version as duplicate content, which is obviously problematic. Also, because the single page has the added parameter on the peramlink (?singlepage=1), I’m wary of setting that as the canonical URI.

Is there any way (short of going in and trying to rewrite the plugin, which I’m reluctant to do and which is really beyond my technical comfort zone) to:
– Change the permalink to the single page view (for instance, so its URL becomes /articletitle/allpages/ rather than /articletitle?singlepage=1), and/or
– Give the single page view a distinct title, and/or
– Set the single page view to noindex and perhaps nofollow the link to that view?

I know there are several premium add-ons for PLP, but I’m not at all sure from their description if any of them address this issue. I don’t need scrolling or auto pagination and this isn’t really a style/formatting issue.

Thanks!
