For the last two days I have been getting above average traffic on my website. Most of these visitors have an average duration of under 15 seconds. While there are not that many more visitors than usual (see Aw Stats screenshot below), there are way more page views and hits.
I'm running Wordpress and have Jetpack stats installed, these high numbers are showing up as page views and are not bots (apparently).
I use Cloudfront as the CDN (I only host images here though) but I'm not seeing a huge increase in http requests from Amazon - which is weird considering the high page views.
I am considering using CloudFlare but I'm also wondering if anyone can give me possible ideas of what could be causing the traffic spike? Perhaps this is referral spam I'm not recognising or maybe a targeted attack?
Here is a screeshot from Aw Stats of the traffic spike (1, 2 November are normal traffic days):
