And the first non-paid for link on google is my post of 2 days ago:

The HTML for this page sets PeakD as the canonical source

This is correct, I should have used hive.blog throughout but got tempted by the 'Topic' box that peakd offers in the editor:

From this I conclude that it is OK to be using hive.blog links?

Thanks for your comment.
