That's a good point, we changed domains on October 9th last year and redirected all pages from the old site over. Link Explorer seems to be picking up all these though. Could there be a delay on the linking domains to the old site being passed through?

Whilst I appreciate this will be better in the long term, we've seen a 27 point drop on DA whilst our competitors haven't changed! Will be digging though all the data but there's no obvious reason for this huge change.
