I spoke to an expert on advertising, Marcus Hutchinson, who gave his time for nothing because that might lead to me paying him, which seems reasonable.
I told him I want to reach more people with my book, A Speccy Man Has A Breakdown. But I refuse to install Meta’s surveillance “pixel” on my website. How to know, then, if my ads are working?
His advice: edit the checkout in my shop, adding a question about how buyers heard about the book.
This seemed an excellent idea, and I have done that.
I wrote a longer post about this, explaining why I still haven’t done any more ads.
