Backlink Filters

Filter 1

Links1

Number of backlinks based on acceptance criteria in Filter1 and sample backlinks attained.  Values reported are factored to Link: values.

SE ANALYST recognizes 3 URL conditions, each of which requires a different way of handling and reporting link related metrics.

URL in SERP

Backlink Handling

No path

Attain sample of external links only.

With path

Not redirected

Attain sample of external and internal links

Redirected

Attain sample of external links from both reported URL + source of redirection.

Only external links are reported and calculated as follows:

Links =       (Sample links that pass filter condition)

                     x (Link: / Number of samples analyzed)

PR values are calculated using both internal and external links as follows:

PR =           (PR from links that pass filter conditions)

                     x (Link: / Number of samples analyzed)

                     + (PR from internal links)

Kurtosis values are calculated using external links only and include PR from links that pass filter conditions as follows:

                  (fourth moment about the mean)
Kurtosis =  -----------------------------------------------------   -3
                                    Std Dev^4

Link count computations for Phrase, Broad and Part matches are handled differently.  Anchortext on backlink pages will be counted according to the following rules.

Phrase Match: One count for one or many phrase matches found.
Broad Match: One count for one or many Broad Matches found ONLY when there are no Phrase Matches within the backlink anchortext.
Part Match: One count for one or many Part Matches found ONLY when there are no Phrase or Part Maches within the backlink anchortext.  If there is a Phrase or Broad match within the backlink anchortext, Part Matches will not be recorded.
