Gooogle announced today that it has made a change to its algorithm that is supposed to make it easier to find multiple pages from a single site.

"For queries that indicate a strong user interest in a particular domain, like [exhibitions at amnh], we’ll now show more results from the relevant site," says Google software engineer Samarth Keshava. "Prior to today’s change, only two results from www.amnh.org would have appeared for this query. Now, we determine that the user is likely interested in the Museum of Natural History’s website, so seven results from the amnh.org domain appear. Since the user is looking for exhibitions at the museum, it’s far more likely that they’ll find what they’re looking for, faster. The last few results for this query are from other sites, preserving some diversity in the results."

"We’re always reassessing our ranking and user interface, making hundreds of changes each year," adds Keshava. "We expect today’s improvement will help users find deeper results from a single site, while still providing diversity on the results page."

This change may prove to be helpful for a lot of searches, but they could still do more in this area if you ask me. For exmaple, they could rank tag pages (commonly used on news sites and blogs) as top results for appropriate searches.

For instance, if I search for "WebProNews SEO articles" or "SEO articles on WebProNews", it couldn’t get any more relvant than the WebProNews SEO tag page. That points to every SEO article we have. Yet, this result is nowhere to be found for either query, and it’s certainly not unique to us (ironically, another article in which I made a similar complaint ranks at the top). These pages aren’t often linked to, so they don’t get the PageRank, but does that make them less relevant for queries like this?
