It appears that Google have made changes to their ranking algorithm over the last weekend.
Google does not usually confirm precise details of algorithm changes and this time was no exception. Google tweeted broad details about dramatic ranking changes back in November following complaints around ranking drops. However, the November updates would appear to still be ongoing given that, over the last weekend, some large websites reported ranking drops of 20%-30%.
Google have remained tight-lipped with no further updates since their November tweet. Their only comment has been that there is no action to be taken by website owners and that there is nothing to fix.
In summary, if you saw your website’s ranking shift over the past few days, you’re not alone. Google definitely made changes of some description.
We certainly noticed a slight dip over the weekend of Sat 8th Feb/Sun 9th Feb across most of our client websites. Since then, all of these sites have recovered their position with some seeing a significant improvement.
