What does ROI mean in betting?

ROI (Return on Investment) is total profit divided by total staked, shown as a percentage. It is the fairest way to compare tipsters.

A value bet is one where the odds offered are longer than the true probability of the outcome — the core of any winning long-term strategy.

What is the difference between backing and laying?

Backing is betting for an outcome to happen. Laying, available on betting exchanges, is betting against an outcome — you win if it does not happen.

What is the overround?

The overround is the bookmaker's margin: the implied probabilities of all outcomes total more than 100%, and that extra is the bookmaker's built-in edge.

Ante-post: A bet placed well in advance of an event, often at bigger prices. In most cases your stake is lost if your selection is withdrawn before the event starts.
Asian Handicap: A handicap market that removes the draw using half and quarter-goal lines, splitting your stake to reduce risk compared with a traditional handicap.
Bankroll: The total pot of money you have set aside specifically for betting. Sensible bettors only stake a small, fixed percentage of it per bet.
Draw No Bet (DNB): A bet on the home or away team where your stake is refunded if the match ends in a draw.
Dutching: Splitting your stake across several selections in the same event so that you win the same amount whichever of them comes in.
Each-way (E/W): Two bets in one: half the stake on a selection to win, half on it to place (finish in the top few positions per the bookmaker's terms).
Evens (Even money): Odds of 2.0 (or 1/1) where you win the same amount as you stake. An implied probability of 50%.
Fractional Odds: The traditional UK odds format (e.g. 5/1). The first number is your profit relative to the second number staked.
Push (Void): A bet that is settled with no win or loss, with the stake returned — common on handicap and totals lines that land exactly on the number.
Return on Investment (ROI): Total profit divided by total amount staked, expressed as a percentage. The truest measure of a tipster's or bettor's performance.
Stake: The amount of money placed on a bet.
Yield: Similar to ROI — the average profit per unit staked, used to judge a tipster's efficiency independently of stake size.
