I agree with the others. 'Remarketing' is the way to go. If you have a loose idea, try and think of the multiple routes you could go down, or what different examples you could use to make a point.

I'd suggest reviewing old content. It's probably out of date anyway, so it's a perfect excuse to make it relevant oncemore and use hand it over to a another website you use.

If there is an opportunity to relate your content to what's going on in the news (i.e. up to the minute relevancy), it's good for indexing, sharing and hits.
