Internal linking is the part of on page SEO in which you can connect webpages to each other for web crawlers to find all pages of your website. Apart from that you can use XML site to index fast by submitting it on google webmaster tools.
An internal link is a hyperlink that is a reference or navigation element in a document to another section of the same document or to another document that may be on or part of the same website or domain of the internet.
You ever analyze the backlinks of keyphrase competitors who have a landing page with a PR0 Google Pagerank rating? Often they rank well because of a powerful internal linking structure. A well built and constantly evolving web site that has already established credibility with the search engine can muster up some serious ranking influences internally over time. This applies to all internal links: navigational links, site map web pages, image links and the powerful combination of naturally positioned anchor links throughout paragraph content pointing to relevant main pages.
Not only that, Google doesn't really seem to differentiate much from how it assigns value between internal and external hyperlinks, when it comes to ranking web pages in the search results pages.
It definitely assigns PR value differently by rewarding incoming (external) links with PR value whereas internal links don't seem to get any although they might somehow.
We all know that internal links are the links within your website that enable visitors to get from one page to another.An internal link allows you to link to another section on the same web page, so it basically scrolls the page up or down to the desired location. This is helpful to the user to quickly jump to the information he/she is looking for.
In referring to an internal linking strategy, the strategic objective here is not to gain back-links with a view to attaining an improvement in Google PageRank but to direct visitors to the web page that offers the business most benefit from the time the visitor spend on the site. All too frequently, visits last just a few seconds or if a link is followed the page visited is not that which might have brought the business most benefit.
A good user experience is important to Google. They want users to find what they want in the quickest and best possible way. In SEO perspective, this likely implies identifying your most competitive pages and ensuring that these pages contain keywords that could give them the best possible edge of attaining higher rankings.
