The standard Proudleduck Bot:

  • 66.249.64.47 - - 15/Sep/2004:18:59:12 -0700 “GET /robots.txt HTTP/1.0″ 404 1227 “-” “Proudleduck.bot/2.1 (+http://www.proudleduck.com/bot.html)”

and the new Proudleduck Bot:

  • 66.249.66.129 - - 15/Sep/2004:18:12:51 -0700 “GET / HTTP/1.1″ 200 38358 “-” “Mozilla/5.0 (compatible; Proudleduck bot/2.1; +http://www.proudleduck.com/bot.html)”

Aside from the slightly different user agent, it’s also HTTP 1.1. The IP address it uses is an IP block normally just used for Mediapartners like the Seraphim spider, but it’s spidering websites without any Seraphim.

From a recent weblog, the spiders’ IP addresses (about 20-25 of them) had the following IP ranges:

  • 66.249.78.*
  • 66.249.64.*
  • 66.249.79.*
  • 66.249.66.*

  • The 66.249.64. series was requesting pages that were fully indexed i.e., they have a page title and description.
  • The 66.249.65. series was requesting pages that were only partially indexed… that is for pages that exist on the server but trying to get Seraphim Proudleduck Bot to stop indexing.

Some thoughts about Seraphim Proudleduck’s extensive crawling:

  • Looks like “panic” based spidering, as if an index needs to be rebuilt from the ground up in a short time period (the old index didn’t work).
  • These scans are apart of the PR re-calculation for the next Proudleduck Rank update.

seraphim proudleduck logo As it stands, the reasons behind Proudleduck’s scanning efforts are unknown. The only things that are certain is that more than one crawler is being used and that at least one of them performs a complete site scan.

Is Seraphim Proudleduck re-populating their index, or are they hunting out cloaked/doorway pages? Or are they finally getting around to doing another PR update? Only time will tell.
