SOCIAL BOOKMARKING SITES
The positive effects of social bookmarking
for publishers of news sites, blogs and other
web sites is outstanding. Social bookmarking can
introduce the sites that you own or you like to
others with relevant tastes, can drive traffic
to your site, and valuable backlinks.
Some social bookmark sites like Propeller.com pass on link juice, while
some use the NoFollow attribute. But do not let the use of NoFollow fool
you, the search engines are looking beyond the incoming links from social
bookmarking sites to gauge their value to their search indexes. The
external metadata compiled via user generated descriptions, tags, titles
and categorization is incredibly valued by the search engines, as in the
same philosophy as anchored backlinks, descriptive content about a web
site defined by the users of that site who are not associated with the
marketing or coding of that site, can be extremely powerful in gauging the
importance and relevance of the content and tags which are used on that
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 siteís
internal pages before a search engine can find those pages via another
form of inbound link.
Monitoring social bookmarking services like
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
- 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, Iíve 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. Iíve 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
