Google
modified its ranking algorithms
Google has
recently made changes to its ranking algorithms.
There are no official words from Google but it
seems that the changes has been made to fight two
phenomena that worried Google:
-
"Google
bombing"
-
selling
advertising based on Google PageRank
"Google
bombing" means that a lot of web pages link to the
same web page with the same link text. For
example, if you searched Google with the phrase
"go to hell", the number one result was
microsoft.com because many web pages linked to
microsoft.com with that exact phrase.
With the latest Google
update, searching for "go to hell" no longer takes
you to microsoft.com.
Then there are sites that
sell text ads and links where the prices are
determined by the Google PageRank of the sites. This
means that you'd pay for a link to your web site
depending on the Google PageRank of the other site.
Google doesn't like it.
Links are not placed because the linked site has
important content but because the linked site has
money. If many sites would sell their links, then
Google's PageRank algorithm wouldn't work.
So what has
changed in Google ranking algorithms? There are
some hints:
-
To stop
Google bombing, Google now seems to check link
texts with the link web site. If the link text
doesn't appear in the linked site, then the link
is ignored or degraded.
-
To stop
PageRank monetization, Google seems to put lower
value to link texts if the linked pages don't
have a high PageRank.
Some people claim that the
algorithm changes degraded the quality of Google's
search results.
