Here’s a power-searcher tip that didn’t get much attention the first time around, so I wanted to mention it. Tara Calashain recently wrote about changes to Google’s date search features.
Previously, I believe Google estimated the age of a url as the last time that we fetched that page. Given how quickly Google refreshes its main index, that didn’t mean quite as much recently. Now for date-based search, Google estimates url ages by the first date that we saw a url.
