Thanks Bernadette.  True, I have noticed some movement in the past on other sites that I manage but these links have always been a constant on my site and it was just a bit of a heart-attack moment to see back-links drop from almost 1900 to 91.

Hopefully it settles over time and there is no impact to SERPS I guess we'll find out in due course

Interesting situation when I looked at Google Search Console this morning, I found that back-links from directories had dropped off and am wondering if anyone else is seeing this?

Specifically, I am in Australia and had links from Yellowpages.com.au and Truelocal.com.au to my primary domain.

Interestingly, Yellow Pages had gone a bit crazy recently in that the number of links to my site seemed to balloon exponentially from about 50 when I first listed to 700+ to 1500+ to 1800+ and then the balloon popped. Truelocal in contrast was only ever showing the 1 link.

There have not been any changes from my end, and I only ever had one listing in these directories so not sure what generated all these extra links in Yellow Pages.

Anyone else in Australia noticed a sudden drop off in Google Backlinks from Directories?  If not it may just be a temporary blip.
