Most important customer lost

According to our log files, we lost the most important customer of bookalizer: http://www.weiterbildung.in.nrw.de/. They used to integrate our services what led to > 100.000 generated ads per month. In April, they switched to an amazon feature that looks quite nice … but it’s really bad! Our ads were based on the context and keywords of the page and they matched the courses presented on the page. Now, amazon seems to display random books – you get book advertising about Dalai Lama and books for children when you are on a page about a HTML course. Very strange. Please, you guys, switch back to bookalizer!
Nevertheless, we had > 16.000 generated book ads in April which is not that bad.
