What is the best method to promote inner web pages? Suppose if a site has more than 100 pages how to build back links for all that pages.
There are several ways to get backlinks to your inner pages. My favorites are: 1. Article marketing - I happen to like Squidoo and HubPages. 2. Free blogs - Blogger.com, etc... 3. Social Bookmarking Sites - These work best when you can create a link to your submission from a 3rd site (this helps get the submission indexed.) These can work to get your inner pages indexed and ranking. Of course the best way is to create high quality content that others want to link to on their own.
I would say if you would like the easy route start by submitting your pages to social bookmarking websites and grow the traffic from there.
I would recommend using an article submission service like Unique article wizard, Free Traffic System, or Article Marketing Automation. They allow you to rotate keywords and urls in the article and author's bio
Inter linking the content keywords is also a best approach where in the PR juice will be passed onto individual pages too
The best way would be to build links to your sub-pages, pick a keyword for that page, and go from there. Its better to have your links spread out throughout the site, so it makes it easier for you to rank for various different keyword.
All the pages should be well optimized to be easily considered by Google and other search engines. And build links for sub-pages based on the targeted keywords.
if your site have lots of pages then do first internal linking i.e promoting your home page then start back linking point towards home page of ya site.
That's a good advice. If you have 1 keyword per page, start optimizing on-page and then bookmark, write articles and post links in blogs
Bookmark your inner pages, put inner page links on article submission, use inner page link on blog posting that helps to build inner page backlinks.
