| Link popularity is a complicated affair as each out bound
link receives a portion of the page value, and this is again adjusted for the number of
out bound links to the target page. The quality of the link is determined by the number
of similar words between the current page concerned and the target page, as well as the
current ranking of the current page.
Each time the search engine adjusts one value it influences another which will have
some influence on the page in question.
Search engines have a very intricate algorithm which takes many factors into account.
Link popularity is just one part of this complex task and is in it self a very strange
affair as there are no fixed guidelines as to when this value is too high, how ever if too
much of the value of link popularity comes from one single page then the search
engines punish both pages, and the host site to some degree.

The value of the link popularity of a page is adjusted for
the quality of each incoming link, and so is constantly changing in value as each of the
following values are interdependent
- Value of the out bound link
- value of the link popularity of the target page
- value of the link popularity of the current page
- Score for common words on each page, which gets adjusted each time the link popularity
is adjusted.
If these pages refer to each other directly then these adjustments are more serious
than if they link indirectly to each other.
The total number of links to a specific page is important, but there is a floating
limit of link popularity that is credited to any one page by any one domain which is
dependant on the ranking of the domains own total link popularity excluding internal
links.
Search engines guard their algorithm with great care and do not disclose too much
information to the public, which leaves thiose who optomise pages for search engines in a
bit of a delema. There are how ever guidelines which are issued by some searchengines from
time to time. |
