Bookmarks show how a site is perceived, and when these sites allow voting, they also show the engines or whatever classification system which monitors voting, how people feel about the quality of the site. Furthermore, social bookmarking can introduce a site to the search engines, as in some cases, people may find and bookmark a site or a site’s internal pages before a search engine can find those pages via another form of inbound link.
Monitoring social bookmarking services like Del.icio.us, StumbleUpon and Ma.gnolia can help search engines in multiple ways by:
Indexing Sites Faster : Humans bookmark sites launched by their friends or colleagues before a search engine bot can find them.
Deeper Indexing : Many pages bookmarked are deep into sites and sometimes not as easily linked to by others, found via bad or nonexistent site navigation or linked to from external pages.
Measuring Quality : Essentially if more users bookmark a page, the more quality and relevance that site has. A site with multiple bookmarks across multiple bookmarking services by multiple users is much more of an authority than a site with only several bookmarks by the same user.
External Meta Data : Users who bookmark sites tag them with keywords and descriptions which add an honest and unbiased definition which is created by the public and not the owner of the site.
Co Citation : Social bookmarking sites tend to categorize sites and pages based upon the tags used by humans to describe the site; therefore search algortihms can classify these sites with their peers.
Number of Votes : Similar to the number of bookmarks, the more votes a page receives on Digg or Reddit, the more useful that information usually is. If the same page receives multiple votes across multiple social news voting sites, the higher quality the site.
Categorization : Like Co Citation, categorization can help define the subject of a site, therefore better helping the engine address searcher intent.
To help share the wealth of social bookmarking, I’ve put together a list of 125 social bookmarking sites, some of which are very popular and others which are newer or somewhat unheard of. But besides targeting the major social bookmarking and tagging sites which are listed above, you will find some diamonds in the rough which are niche oriented or treated well by Google and other search engines. I’ve found that one such surprise is Searchles which is regarded as an authority by multiple search engines and bookmarks within Searchles sometimes show up quite high in some branded organic results.
