Additionally it may be the case that a large part of the value of the algorithm is created from its secrecy. If the algorithm was open it would be trivial to create sites with artificially high rankings which would reduce the value of the search results.

> If the algorithm was open it would be trivial to create sites with artificially high rankings I don't necessarily think this is true. Sites that have high page rank, do so because other sites of high value link to them. Even if Google open sourced their search engine, spam sites would still have a hard time getting high quality inbound links. The reputable and high ranking sites wouldn't have any increased incentive to link to low quality spam sites.

  It's not the ranking algorithm specifically that's a secret; it's the code that used to detect sites that work together to artificially raise page rank of another site by linking to it. The whole Page Rank algorithm is predicated on the idea that human website owners and contributors do a better job at assessing the value of a website and they express this by linking to the website. When links are created for other reasons they reduce the effectiveness of Page Rank, and when they are created specifically to bias Page Rank they do the most damage to the algorithm's results. Keeping the algorithm secret, and in particular the tweaks that eliminate links which aren't expressing "I judge this to be a good site", keep Page Rank useful.

  Absolutely. I've worked in several contracted roles within online marketing and I've heard some awful advice from self-proclaimed SEO gurus about how to achieve a high rank for keywords on Google. A lot of what achiving high ranks is about is common sense and as Google improves their algorithm fewer tricks work. Anything past a simple competitive analysis, keyphrase analysis and a backlink analysis on you and your competitors is overkill. The quality of SEO analysts out there is so poor that I believe you could release the source code to Google's entire search engine and people would still get things wrong or believe in ways to get around what I assume is an extremely complex set of mathematically-oriented algorithms. It's a classic example of the blind following the blind, and those that typically have followers are those that are popular for performing SEO work on huge companies that would never actually need it (e.g. Coca Cola).
