I'm not sure if it still makes sense to look at the performance of the Entreprenerd website. I have the impression that many of the visits are irrelevant. The average engagement time is 3 seconds. That's not a good result.
I still can't explain the many visits from Finland and The Netherlands.
And the metrics of the user acquisition doesn't make me any wiser.
The Google Search charts are more reliable and they show the effect of the season's holidays.
The keyword "itext" is usually in the top 3, but last month, it lost that status to "lowagie" and "entreprenerd"; only the combination "lowagie.com itext" still refers to the PDF library in the top 3.
The sales numbers of the book form a better KPI to measure the performance of the website. I hope for some hardcover sales, because I haven't had one of those since September.
