Data, charts and examples
The overall effect of the December core update was large – far exceeding absolute changes seen in the November core update. Here are some of the major movers.
Health websites were clearly affected in the update with webmd.com being on of the biggest losers. Verywellhealth, another established health information provider, was also down.
Competitor gains by mayoclinic.org (+18.32) and www.nhs.uk (+21.56) weren’t as pronounced but significant in their absolute values.
Changes also spread across the ‘vip and personal brand’ space with mirror.co.uk losing a over 90 of visibility in their /all-about directory.
Changes were also seen in instagram.com (+32.55), wikipedia.org (+95.06), spotify.com (+17.10), imdb.com (+12.44) and primevideo.com (+ 2.46) indicating that personal brand / VIP rankings may have shifted to ‘owned’ reference sites.
Retail sites were also affected. From a list of 453 Retail domains active in the UK there was a net gain despite multi-brand retail sites amazon.co.uk, etsy.com and ebay.co.uk falling.
On the losing side, sainsburys.co.uk, hm.com and prettylittlething.com were the top losers but these were smaller in comparison to the winners.
