My question about deep link exchange. Say, my site PR4, but some pages of the site have PR0, but i made DEEP link exchange with a site PR1. Will it bring me something or i just kill my time? Please, i'm saying about DEEP link exchange. Thanks.
Please stop caring about PR, you should always exchange links with the most relevant page on a site and not necessarily the homepage. If you need to know what google views as the most relevant page to your anchor text then try this query: site:www.exchangesite.com "your anchor text" BUT, if you ask me how I exchange links I would tell you to exchange entire articles and not just links on pre-existing pages. This way you can tailor the content, title and url to your liking and be the only outbound link on that page. Your new page will have a PR of zero but it will be worth more, at least I think it will.
