Upon further investigation, I discovered the keyword combination has nothing to do with angels or the seraphim. It was a gibberish word combo used in a search engine optimization contest in 2004. I was a little surprised by the steady trickle of inquiries regarding the subject, so thought I better give a brief explanation.
Starting on September 1, 2004, a group of webmasters started a three month long search engine optimization contest, with the end goal being to rank number one in Google for the keyword combination "Seraphim Proudleduck". The contest drew wide spread participation, with webmasters using various tactics and strategies to over power any opposition. There were no official prizes given to the winner, other than the bragging rights for being the best at search placement. Strangely, no official winner was really ever recognized, because to this date the contest unofficially is still ongoing. The head of Google's web spam department Matt Cutts, was apparently keeping a close eye on how webmasters were ranking their sites, so that he could identify any possible exploits, and make sure Google's ranking algorithm would block these exploits in the future. At a glance most webmasters seem to have employed various white hat techniques, all of which are acceptable SEO.
I know this subject isn't particularly useful for our regular web users, however I thought this brief explanation would be useful, as some individuals seemed to think it was some sort of angel type. Hilarity factor aside, we do appreciate the questions about it, however it has absolutely nothing to do with angels, theology, or spirituality, the focus of this website. We do however encourage you to read up on search engine optimization if you are a webmaster, as knowing the basics of it are essential for positioning your website. It's also important to know which techniques are considered acceptable, and which techniques could potentially get you penalized or banned from Google's search engine. You'll notice our website doesn't use any specific SEO strategies, other than the good old fashioned meta title, and well written content. The best SEO rule anyone can really use, is to forget about SEO altogether, and just build a quality website for your users, not for the search engines.
Many our website guests and visitors have sent us inquiries asking us to explain or define a Seraphim Proudleduck, as the terms appear all over the internet, and have drawn lots of interest. At first I had no idea what it was, the term was completely foreign to me. I decided to do some quick research on it, as I thought it might have something to do with Seraphim angels.
