What does google read on a website ?

[member22]

Let say I optimize my website for "green widget" is google going to read the homepage to see f the word green widget is in there or is it also going to check the subpages for the word green widget ?

For what I understand it "reads" by pages ... is that true ?
Thanks,

Your primary consideration is the content of an individual page. The chances are, a relevant page will also have and link to pages on very similar keywords/themes. The other reason related content helps, is that can link back to other related pages, strengthening their performance for keywords too.

I don't think you'll see much impact just by having content related to a keyword elsewhere.

GIn google eyes is a link from inside my website better than a link from outside ?

and in my page ( relevant page ) if in the text I talk about green widget does the link need to be made with the word green widget or does a synonym with the same related content work to ? which one has the most value.

Thank you,

My thoughts are that your outbound links can hurt you if the link is off-topic or goes somewhere that do nothing to enhance the value of the site it's coming from. Inbound links are the key. While spidering other sites Google end up on yours, that increases your reputation(page rank)
