I noticed an increase in direct entry traffic which averaged to 20-40 visits a day.
For the last two days it was 146 and 280 respectively. I checked visitor logs, and found various IPs, different countries, OSs, plugins, ISPs. It’s always to the home page. Some continue browsing, but most end their visit on the home page.
I wonder if there is any situation where it is actually not a direct entry but somehow Piwik is not recognizing it. I haven’t noticed this on my other sites.
