What is the most important metric for judging a tipster?

ROI (return on investment, often called yield) over a large sample is the fairest measure of profitability. Strike rate alone can be misleading because it ignores the odds you bet at.

What's the difference between yield and ROI?

In betting they usually mean the same thing — profit divided by total amount staked. Some sites calculate ROI on bankroll instead, which inflates the figure, so always check the definition.

What is expected value (EV) in betting?

Expected value is the average result of a bet if it were repeated many times. A positive-EV bet makes money on average because the odds are bigger than the true probability of the outcome.
