Does google consider a link from irrelevant site as a "vote" for your site such that it will help in boosting your PR? OR google just count that as Zero? OR google penalize you because it seems to be a spam? what do you think?

G can tell what topic your site is about.

Whether it dilutes links from one topic to the next is arguable.

I think G gives the website the benefit of the doubt and allows some mixing. I just use my brain on what I think google would allow not so much as what it should allow.

Also... run adwords on your site. I see ads on my site that are a bit off topic all the time (but they are the most high paying ones). If G is'nt smart enough to serve the right ads than it isnt smart enough to tell whether the two sites are unrelated.

IMO - It would be a massive blow to adwords if it served supper specific ads. There will always be a grey.

Say I wanted to do a massive link campaign... I would check to see what sub categories fall under the "Site flavored" categories. If I have a question about a site... I see what G thinks about it.

we know:

- Google can detect the general theme of a site - not always accurately, but still to a certain degree.
- Google can determine relevancy of a page for a given site to a specific term (they do it for every search performed).
- Google is now public and has a huge budget for computational power.
- Google updates less frequently than before, thus allowing for more computations to be performed before updates.
- Google caches entire pages.
- Google can determine stemmed keywords.

Now, does anyone sincerely believe that Google considering the theme of sites linking to you is unlikely?

Even as a very basic example, if page A links to page B:

- Determine all words with density x% or greater on Page A.
- Determine all words with density y% or greater on Page B.
- If Page A does not contain at least z% of words contained on Page B or words stemmed therfrom, Page A is not on-topic and therefore the link is probably a manipulated link and should therefore be discounted.

Extremely basic and of course not accurate, but when you have as much data as Google has, you can play around with methods until you find a variation or a combination of similar theories that produce enhancements to rankings.

On a site or page basis, I don't know - but I bet they do!

Of course, PR (as in the decimal number we see) is probably unaffected - but ask any SEO these days and you'll hear that PR doesn't mean even as fraction as much as it used to say 3 years ago, so even though your PR goes up - "ranking power" may not.

And finally, I'm not saying the DO this, but it's certainly within the realm of possibility. I mean the competition is getting stronger, they have to explore new things!

If that's the best they can do - I stand by my post.
