Quantity of Internal Links

This point is simple; the more internal links you have that point to a certain page, the more important search engines believe that page to be. A common page that ranks well on almost every site is the homepage. This point will continue to be true for many years because nearly every webmaster programs their site so that every page has a link back to the homepage. So how do make your other pages benefit from this? Does that mean you should have every page on your site include a link to EVERY SINGLE PAGE in your site? No. That's an obvious red flag to search engines, and you'll be seen as a spammer if your site has a couple of paragraphs and then 500 links to every other page on your site. A better strategy would to have a "Top Products" section that includes a link to pages you want to receive the most link love. Another strategy is to have a link for each of the major areas of your site. This will help give those areas a lot of link love, and in turn, they'll be able to get more link love to the pages contained within them.
