It is just summer, especially in Europe. many companies close down for an entire month and employees often take very long vacations. Schools are all closed, life becomes quiet, better to be at the beach.
Projects get delayed or simply shelved until September when everyone is back.
The US has much less vacation time but even there a lot of business projects get scheduled for September.
Travel content, back to school, maybe some autumn can help to fight the summer slump.
For me personally June-August is a yearly death zone.
My ranking has improved even though sales are very slow, so I take this as a general downtime in sales overall.
