These are pages listed in Google’s search results alongside normal results but labeled as a ‘Supplemental Result’. They come from a Supplemental Index maintained for lower quality pages. See the definition of a supplemental result at Google’s Help Center.

Supplemental pages are generally considered less trusted and rank lower than pages in Google’s main search index. Pages enter the supplemental index for a number of reasons:

• They have limited number of links pointing at the page (internal and/ or external).
• They are similar to other pages in a site (duplicate content).
• The URL for the page is exceptionally complex.

Best of The Web directory is offering a 20% discount on it’s review fees this month (June).

Even minus the 20%, the $200 one-off review fee (non-refundable) is pretty steep, but it will give you a high quality link to your site. Just make sure your site is a quality one or you may lose your hard earned cash for nothing!
