It is a simple one step process: shove unasked advertising in my face. Bonus points for loud full blast audio right of the start.
If I ever see unasked advertising that tried to be sneaky or not do sneaky I am going to block it without noticing from whom or for what it was.
But when it’s shown so often and is so intrusive that I take note of your brand. That brand is not considered for future business anymore.
That is especially for services where I am the product paying with my data.
