External Followed Links in the Competitive Domain Analysis Report

[PGD2011]

In the Competitive Domain Analysis report, why does the number of my external followed links vary over time. Some weeks its high some weeks it's low. Doesn't seem to be a pattern.

[KeriMorgret]

We update the index every 3-4 weeks, so that would account for much of the variation in the links -- we find sites that no longer have a link to you, or we don't crawl a particular site in that crawl, etc.
