Our organic search traffic went flat for 2 weeks Oct 2 - Oct 17\. It has since resumed to more normal numbers. Anyone have any idea why this would happen?

Does anyone have any insight as to why our organic search traffic would go to nearly nothing for roughly a 2 week span Oct 2 - Oct 17th?  Our regular traffic remained fairly consistent so we were still being indexed.  It has now resumed to more normal numbers but I cannot think of anything we did that would make this happen? We did make a 302 switch to be a 301 permanent redirect on our site in early August but that is all I can think of? Any insight or help would be appreciated!

Thank you for your response. All organic search dropped - google, bing, yahoo, etc.. Index status looks normal through that time period. Impressions and clicks carried the same pattern as usual - no change there.

Since only your organic traffic dropped and the reported time frame corresponds to some Google algorithm updates an explanation for this may be that your website lost some rankings for keywords that were bringing you good amount of traffic.
After changes to Google algorithm settled you probably regain the rankings.
I repeat, this is my presumptions in case only your organic traffic dropped.

If all your traffic dropped it may be because you have some website downtime...

Or it may be that your traffic didn't drop, just your tracking tool had difficulties (maybe someone  in your team accidentally uninstalled tracking code from some of the pages)

All search engines or "just" google? If only google, did the number of indexed pages change during that time?  What about the number of query impressions verses clickthroughs?

It was not totally flat but huge difference. The weeks prior were holding steady at roughly 5K organic visits per week and then for 2 weeks dropped to about 300 per week.

Was it just reporting as flat or did it actually go flat? Big difference there.
