常见问题
What is matched betting?
Matched betting is a technique that uses bookmaker promotions (free bets, bonuses) to make a guaranteed profit. By placing a back bet at a bookmaker and a lay bet at a betting exchange, you cover all outcomes and extract value from the promotion.
What is the difference between SNR and SR free bets?
SNR (Stake Not Returned) means if the free bet wins, you only receive the profit, not the free bet stake. SR (Stake Returned) means you receive both the profit and the free bet stake. SR free bets are more valuable and have a higher conversion rate.
What exchange commission should I use?
Most betting exchanges charge 5% commission on winning lay bets (Betfair standard). Smarkets charges 2%, and Betfair may offer reduced commission rates. Enter the rate that applies to your exchange account.
How do I minimize qualifying losses?
Choose events where back and lay odds are close together (small overround). Lower odds generally result in smaller qualifying losses. Look for odds between 2.0 and 5.0 where the back-lay spread is tight.
