Page is a not externally linkable

That was some very specific words. Although these concepts indeed could give some insight on how Google works (as well as a lot of other things), i really don't think that you have to know any mathematics at all to produce a good (ranking) website - and you don't have to be a PhD either. These are just tools for analysing complex sets of interdependencies. It sounds pretty advanced, and it is, but it will not really help you create that super site, as these tools are used for entirely different purposes. Go create that super site instead. Don't be afraid of links coming in or links going out; specifically, dont try to control the free flow of linking power. Nobody really can do that 100% anyway in the real world, not even the big household brand names. Dawe_Hawley might be considered an "optimist" or even "SEO ignorant" by some for the things he said earlier, but that's an uninformed view. To me, what he says makes a lot of sense, you just have to dig a little deeper. SEO might not be SEO in all cases. And that is not the same as a SEO penalty. What they do is to assign weights to all kinds of things and then they rank pages according to those weights. If you page has the highest sum of weights for some term or phrase, you will simply rank highest for that. And, yes, weights can be set to zero as well as any other number - and they keep changing a little now and then. As there are a large number of such weights, you will sometimes see that pages that are not "SEO'ed" at all rank just as high as pages that are. Of course they do that for another reason, as there is not one specific way to the top, but many. (added: filtering, in turn, is an entirely different matter, unfortunately i have no time for that right now, sorry) The Florida update was not a lot about your pages. It was mostly about Google's own pages - specifically that little thing known as the search box. What people type in here is now treated a little different, and it's actually pretty impressive. By all means, it was a minor tweak in terms of page ranking and weighting. In terms of focus and understanding of search patterns it was a major leap. With regard to math: This has never been an equation of second order, so having just one maximum is not really natural anyway. /claus

Google does not penalize for SEO. Google does not penalise for proper HTML coding. Google does not penalize for incoming links or for outgoing links. In general, i will say that Google does not operate with penalties at all. In some highly specific situations, they have to employ some sort of manual tweaking, but in general they will stay far away from that. Why? Simply because it will make their system slow and inefficient, and that is the last thing they will want.
What has changed with "Florida" is simply that pages do not need to rank high for the exact phrase to be in top 10 (i might add; unless that phrase is considered to be an exact one). To webmasters running sites (with pages) that were previously on pages 2-100 that would be an improvement.
With regard to your pages: Use your common sense - that will get you very far. With all due respect, these advanced tools are usually used (with great skill) to produce analogies of "common sense, real life" situations.
