    Thanks Ted, that is very interesting indeed. One thing I would like to query is this:

    “It also includes references to the website that are not a link… but many in the SEO industry speculate that the search engines then convert that into a link and count it.”

    I honestly haven’t heard this elsewhere. If it is correct, doesn’t that have massive implications for linkspam? You can’t apply nofollow to something that isn’t an anchor, so surely there would be huge benefit to a spammer to simply write their URL into blog comments rather than making them links, thereby getting it converted into a link without a nofollow?

    I can’t believe that this is the case, otherwise we would see a deluge of such “links”!

    I tried your formula and found it was way off for three link-popular/reference-popular sites. I suspect it’s not of much value to the broader audience.

    very rough investigation, but still very useful to asses the price of backlinks.

    is that this calculation still works?
