I've noticed the most unsettling pattern in the last few months. This may concern everyone involved in SEO.
Google got in the habit of launching loads of algorithm updates in a short time frame. Every since the Medic update on 1st of August that raged havoc in the medical and health niche Google seems to launch new changes in its algorithm every two weeks or so.
The last ranking shift I've felt was on the October 16 and my ranks are still somewhat volatile ever since.
As far as I could figure out the actual timeline goes like this:
August 1- Medic update
August 6 - Medic Update officially over
August 9 - Huge fluctuations still happening for some reason
August 22 - Possible correction of the Medic update, on this date I got my rankings back from the fall on the 1st.
September 6 - Another shift to take notice off
September 8 - Strong volatility in ranks still present
September 11th - Some kind of algorithm update was implemented, nothing very important, may be related to the number of nofollow backlinks
September 27 - on Google's birthday we get a clear algorithm update, this one is officially confirmed by Google, don't know exactly what it impacts yet
October 8 - Some volatility present, something indeed happened
October 16 - got slightly better ranks all of a sudden, probably an update hope my ranks remain the way they are right now
So there you have it. At least 9 clear examples of algorithm changes in the last 2 months. Sure, Google says it implements algorithm updates every day, but these two months had been a little out of the ordinary, with a bit too much volatility for my taste, August was primarily an emotional rollercoaster for me and probably for most SEOs out there.
Do you think this is the new norm for Google? Constant updates and aggressive rank instability? I personally am not yet used with such constant changes. My heart stands still every time I open my laptop in the morning with the fear of finding yet another organic traffic and ranking drop like the one I've experienced on the 1st of August.
