General advice and example for profit boosts
Place your profit boost bets at high odds to maximise your profits. Use the ‘Qualifying Bet’ setting on the Matched Betting Calculator to calculate your lay stakes. You’ll need to enter your effective odds as your ‘Back odds’. You can calculate your effective odds by factoring in your profit boost.
See my Profit Boosts guide for a complete walkthrough of this offer type.
How to lay a Bet Builder
If you’re looking to lay a football Bet Builder, you’re in luck. All you need to do is add the right combination of selections, and you’ll be able to lay your Bet Builder in one bet at the betting exchange.
Bet Builders on other sports tend not to be as straightforward, and you may struggle to lay your bet. In that instance, and depending on the offer, you may want to treat it as advantage play.
See my Bet Builders guide for a walkthrough of your options.
