More tags means more pages

I discovered something interesting today. I wanted to see how much visility this blog has in Google so I did a quick search. The results showed something which I hadn't really ever considered...but when you think about it becomes obvious.

There were results in the Google SERPS for pages with titles that I didn't remember writing posts for. Such as 'bloglines' in the snapshot below...



Of course, these pages originate from the tags that I've added to each post. Which (of course) got me thinking...each tag represents an optimisation opportunity since it gives my one post numerous different URLs and titles with appropriately rich keywords. Nice.

Is this something you're using on your own blogs from an SEO perspective?
