One way to increase your PR of your website is to add internal links to your website. You might heard that links from other websites that point back to your website (back link) are essential in getting top search engine rankings, especially with Google. These links vary in their effectiveness and value depending on the website from which they’re coming. Internal links can have similar effectiveness and value as external links.
The simpliest way to do for this strategy is to have text links as nagivation at your website footer. Menu likes image and DHTML menu or using JavaScript can be bad for your SEO. Search engines cannot follow image links or links created in JavaScript. So it is important to have search engines to visit and index all your website’s pages.
