I've had a software development portfolio/ blog for a few years with Google Analytics installed on it. I'm not really that bothered about how much traffic the site gets, but nevertheless it's interesting to see some usage data.
I noticed something odd recently with a drop in traffic on the website, which I'm hoping someone might be able to explain.
Here's the situation:
Before February 11th 2016, my most recent post was on September 26th 2014. I hadn't posted in around a year and a half and traffic since around July 2014 was averaging ~70 sessions a day (> 95% from organic search). On February 11th I updated my portfolio with a new blog post and added a single CSS property. From the day after (February 12th) until circa June 13th my traffic severely dropped to approximately 10 sessions a day.
Here's an image depicting the above description (hopefully will show the general trend):
It's started picking up again now but I find it odd that the drop coincided with a new blog post. Is this a coincidence? Again, I'm not bothered about the traffic levels; I'm more interested in the cause and whether there's something I'm not understanding about SEO/ Google Analytics. Perhaps they changed something in their algorithm, or was my website blacklisted for some reason?
