Just did a quick check of all mine and none of them have changed.

haven't notice any change

Since EMD update I think there is no update..

I see some cheanges.

No changes at all for me. Maybe a little change in SERP, but this happens almost every one out of 5-7 days

My authority website changes ranking every week if not more. It doesn't require a Google update to move. It requires you to do good seo then it will move up. Sometimes it takes a while to move up or down google after making the links. This is so that you cant see what links are good or bad. Your movement could be due to seo done weeks or months ago.

No changes for my sites.

Google change their algorithm almost daily so noticing some changes in your ranking is not a surprising issue.Just follow the basics and you will see your previous positions again.

there is no any official algorithm changes ...

In Spanish sites there was and algorith update last nov 16. I lost 30-40-50 % in several of my sites.
Although Google says they didn't do nothing, but that is not true.

Arquigrafico.net

No changes for me too..

Yes at that day my website keywords also shake up. But here good news keywords ranking good.
