How Google determines the relevance of keywords?

Can Google check if 'CD player' and 'Mirror' are not relevant?

Hi All,

I'm trying to find out how Google determines the relevance of a page.

Does anybody have a more info link on this one?

The situation i'm in:

I have a PR7 site from which I can get a link. The only problem is that the site is not relevant to mine. Now I want to add equal secondary keywords to the PR 7 site and to my website. This so both sites share equal keywords.

The only problem is that the primary keywords on both sites are not the same and actually have nothing to do with each other.

But they share some secondary keywords.

To check if this idea would work I have to know how Google determines the relavance.

If Google understand that for example 'CD player' and 'Mirror' are not related, then I guess this idea will not work.

The reason why I think there is change Google will understand this relevance is because it can do a relevance check like wordtracker.

But I don't know If Google is able to do this relevance check.

Hope you all can help me on this one!

Regards,

Wouter

Google has bought Applied Semantics. That being said I don't get the whole point of getting links from related content only. If that's the case then web will not remain web and will be divided into sub-webs :). Maybe someone else might give you a better advice ;)

tribal, on or off topic, if it's a PR7 you'll get PR benefit - that's numerical vote based on the PR of the linking page divided by the number of links on it. For now anyway, that could change down the road some day.

This set for CD player [labs.google.com] can give you one idea of how Google might look at relevance of keywords.

Topic sensitive Pagerank [webmasterworld.com] is a much discussed paper on possibilities - down the road. Whether "going very topical" benefits search results is another question.
I would guess the internet needs more inventory of content and links to factor that in.

Another way Google could look at relevancy is the click-through rate of links on a page delivered by a search query result. (with the Google toolbar for example).
