One thing I noticed recently is that on a couple of sites, I have more pages in the 'filtered results' than I'd like. These are sites with several thousand dynamically generated pages, and that means they also have dynamically generated page titles and meta description tags. Over the past year as Google has tightened up on duplicate titles and tags, I'm trying to find the happy medium between easy maintenance and actually getting the urls into the viewable index. In some cases it seems that just changing one or two words (such as the product name or the city/state) isn't enough.
