PR incresses by Backlinking. Should this be done in all pages as possible.... or is it enough if it works with index page... Hope my Question is clear...
Ideally, you will get links to many of your inner pages. These are called "deep links" and they are helpful. You will probably concentrate on getting links to your home page, and that is normal. But take every chance you can to get links to pages other than your home page as well.
i have added my site in 20+ directories then is it adviced to add all those links in the inner pages... or better stop with few pages...
Getting links to internal pages with the appropriate anchor texts helps those landing pages to rank high on search engines for those keywords, instead of your home page showing in the SERPs. I didn't actually get your second question.. about adding directory links in the inner pages.
I would say that you should stop caring about your PR. What the hell is the PR doing for your income? Start focusing on your SERP, that's whats gives you income!
I concur... but... If you have a page with high PR you could sell text link space in TLA and still make a decent profit. Everything is linked though .. If you have a good SERP position you will have a high PR. This may also help you out:
Before submitting deep links to directories make sure that they accept deeplinks. Many directories only accept links to your homepage and if you submit a deeplink it will result in your submission being rejected.
Geting to index helps the domain page Backlinks to Inerpages get's higher PR there but olso to the main page
Both help. In general, if your deep page has a lot of content that people might link to anyway, then it's worth developing a link building strategy for it.
of course your subpages will help to your main page to get better serp results and page rank. it's a good way to find backlinks
