I explain to him what I would treat and how and he expresses himself very interested.
Going into the details, he finally tells me: “ OK, if you want to speak at our event you have to pay €2,000 .”
I reply: “If I come to the event to share my experience with participants, I invest time, why should I also pay?”
He: “You know, I have to cover the costs, cambodia telegram phone number list pays at least €3,000, so for less than €2,000 no one speaks at our events”
Why
Many strong and institutional training brands (I'm thinking of SDA Bocconi , Cattolica) have a limited training offer on digital topics (perhaps because the teaching staff of the "traditional 4 Ps of Kotler" marketing has not updated itself?!).
So a lot of training on web marketing topics is delegated to targeted paid events like the one described above: some of these are very valid and help to train while others base their economic balance on testimonials (or workshops) which in reality are pure disguised advertisements.
Marketing hype doesn’t help you understand digital marketing and discredits anyone who doesn’t have a strong brand.

Conclusions
In my opinion, if you charge for a ticket to a Web Marketing event , then you must bring testimonials, workshops and quality interventions by selecting speakers regardless of whether they are sponsors; if you do not do this, in the agenda of this intervention you must mention the fact that these are paid testimonials.
I also spoke about it with Emanuele Arosio ( @arosioemanuele ) who had identified a marketing angle on a seminar on Not provided at SES London.
Bottom line, if you don't declare your sponsored ad in Bold on your meeting agenda, you're deceiving your audience and discrediting the industry and you don't deserve your client's trust and time.
