Sign-up bonuses,
terms read in plain English.
Welcome bonuses can be genuinely positive expected value if you read the rollover terms and use them correctly. Skip a bookmaker if the rollover is heavy or the min-odds is steep — the bonus often won't survive the wagering.

A word of caution
Welcome bonuses are designed to extract a deposit from you, not give you free money. A 100% bonus with 8x rollover at min-odds 3.00 means you have to wager 8× the bonus amount on selections where the model gives you ~33% chance per leg. Most users don't clear the rollover. Use a bonus only if you'd be making the same bets without it.
