They should remove that. It'll get them smacked by the google spam team eventually.

  If not already... You really shouldn't do stuff like that. SEO 101.
  - camillomiller 12y ago
    Yeah, and I don't understand why people still do that. It may work. For like a couple of weeks, before you get banned forever. It's even easier to do stuff the right way, especially in a one page design. Just leave the logic up above. Then put a long, well written text about math, the importance of brain exercise and a description of the game with well divided H1/H2 headings, below it. Here's all the SEO you need. The link from HN and all the sites that scrape it will do the rest.

    This SEO spam is not in the Github repository. It seems Michael Jakob knows full well that it is frowned upon.

  Wow it's early 2000's style of SEO - lots of individual words rather than actual searched-for phrases.

  Could Google theoretically calculate the probability that some text on a webpage is extremely hard or impossible for humans to readily see based on info from the source page about the background and text?
  - scrollaway 12y ago
    Not just theoretically. Very concretely.
    - ajcarpy2005 12y ago
      Well I said probability because depending on how complex the background is such as photographs, video, or some weird scrolling behavior, there could be some hindrances to having a computer accurately or computationally-efficiently determine this.

        Google uses filters, which run in different intervals apart from the main algorithm and have different effects for a page or the whole website. This is why spammy SEO tactics often "work for a while" - until said computationally intensive filter catches them and often punishes the whole website. Prominent examples for these filters are Panda [0] and Penguin [1].
