Those questions by their very nature are too subjective to answer.
The “value” of an affiliate is directly proportional to their performance.
This value changes with time, market conditions, their search engine ranking and/or ad budget, experience level etc…
Todays “value” is not an indicator of potential or future “value” An affiliate that previously generated $60k per month in net reveune just twelve months ago may in fact now produce $5k and has a totally different “value”.
The 90/10 rule applies now more then ever. The top 10% of affiliates produce 90% of your client casinos revenue.
Bearing that in mind probably 80% of recruited affiliates end up having no “value” at all.
10% produce moderate levels of income and have “value”.
The remaining 10% are worth their weight in gold and a high enough “value” for them is impossible to establish.
I don’t know how anyone could honestly answer the question as put forth.
