11 Common Matched Betting Mistakes (and How to Avoid Them)

Making money from matched betting is a brilliant way to earn extra money, but mistakes can quickly eat into profits.

From overlooking small details to not using the right tools, even experienced bettors occasionally slip up.

Here are 11 of the most common mistakes in matched betting and, crucially, how to sidestep each one.

Let’s dive into each mistake, with practical steps to help you avoid them and keep your profits growing.

1. Skipping the Matched Betting Calculator

The matched betting calculator is one of your most important tools.

It ensures you’re placing the right amounts on both the back and lay bets to minimise qualifying losses and maximise free bet profits.

Not using this calculator (or misusing it) leads to errors in stake amounts, causing you to lose money rather than profit.

• Solution: Always calculate your bets. Matched betting calculators take into account factors like odds, commission, and profit potential, helping you make accurate matched bets.

2. Confusing Back and Lay Bets

Matched betting requires you to place both back bets (betting on something to happen) and lay bets (betting on it not to happen) on the same event.

Many beginners mix these up, causing losses on both sides or risking their stake.

• Solution: Before placing any bet, double-check that you’re backing at the bookmaker and laying at the exchange. Remember:
  • A back bet means betting that an outcome will happen.
  • A lay bet means betting that the outcome won’t happen.
• Pro tip: Start with a single event to get comfortable with how back and lay bets work before moving on to multiple offers.

3. Overlooking Liquidity on Betting Exchanges

Liquidity, or the amount available for betting at a specific odds level, is crucial when placing lay bets.

If liquidity is too low, you may only get a partially matched bet, complicating your betting strategy and potentially leading to a loss if not managed well.

• Solution: Check the liquidity on exchanges like Smarkets or Matchbook before placing a lay bet. High-profile sports events typically have higher liquidity. If liquidity is low for your chosen event, consider selecting another event or waiting until closer to the event’s start time, when liquidity generally improves.

4. Not Verifying Odds Immediately

Odds fluctuate quickly, especially for popular sports or close-to-start events.

Checking the odds on both the bookmaker and exchange and then waiting too long to place the bets risks losing a good match if odds shift.

This can lead to bigger-than-expected qualifying losses.

• Solution: Once you find matching odds, place both your back and lay bets as soon as possible. Integrated betting tools that connect directly to exchanges can streamline this process and help you react quickly to ideal odds.

5. Accepting High Qualifying Losses

Qualifying losses are a normal part of matched betting when meeting requirements to receive free bets.

However, too large a qualifying loss can significantly cut into your potential profits.

• Solution: Aim to keep qualifying losses to 5% or less of the stake amount. Use oddsmatching tools to find close odds between the bookmaker and exchange, as this minimises losses. For instance, if you’re betting £50 as a qualifying bet, a qualifying loss should ideally be no more than £2.50.
• Pro tip: Look for events where the back and lay odds are very close—often higher-profile events yield the best matches.

6. Failing to Track Profits and Bets

A common mistake is failing to track profits accurately.

Without careful tracking, it’s easy to lose track of which offers you’ve completed, which are still active, and where your money is distributed across different accounts.

• Solution: Use a matched betting tracker, whether that’s a spreadsheet or a dedicated matched betting profit tracker tool.Track every bet and profit margin for transparency and to stay organised. This helps you quickly identify your most profitable offers and see exactly where your money is at all times.

7. Neglecting to Opt-In for Offers

Some promotions, especially those offering free bets or enhanced odds, require you to opt-in before you place a qualifying bet.

Forgetting to opt-in means you won’t qualify for the promotion, resulting in lost opportunities and possibly wasted stakes.

• Solution: Read the terms and conditions for each offer carefully. Most sites will have a clear “opt-in” button for promotions. Make it a habit to confirm you’re opted in before placing any qualifying bets to avoid costly oversights.

---

8. Betting Exclusively on the Same Offers

If you consistently only bet on the same types of bets and the same types of offers, it can raise red flags with bookmakers.

Bookmakers monitor betting patterns and may restrict (or “gub”) accounts that appear to only take advantage of promotions or display “unusual” betting behaviour.

• Solution: Vary your bets to create a balanced betting profile. Occasionally place bets on different sports, leagues, or even smaller events. Aim to resemble a typical punter’s activity by mixing up sports and betting amounts.

---

9. Overlooking Exchange Commission

Betting exchanges charge a small commission on winning lay bets, which affects your overall profit.

Ignoring this commission can result in less profit than expected or even losses on specific offers.

• Solution: Adjust your stakes in your betting calculator to include the exchange’s commission rate (typically 2% to 5%). This ensures your stake amount takes into account any commission deducted from your winnings.
• Pro tip: Smarkets and Matchbook often offer lower commission rates than Betfair, making them popular for matched betting. Adjust the commission in your calculator settings for accuracy.

10. Using the Same Stake Size for Every Bet

Placing the same stake size on every offer, especially the minimum required stake, is a clear sign to bookmakers that you’re likely engaging in matched betting.

This “trigger” behaviour can lead to account restrictions, meaning you won’t have access to promotions in the future.

• Solution: Vary your stake sizes. If an offer says “up to £25,” sometimes place a £20 bet or even go higher than the minimum. This variety gives the impression of more natural betting habits and helps keep your account in good standing.
• Pro tip: Consider occasionally placing mug bets, which are non-promotional bets that don’t generate immediate profits but make your account look more typical to bookmakers.

---

11. Not Setting Aside a Dedicated Matched Betting Bankroll

Without a dedicated bankroll, bettors may dip into personal finances or mix matched betting funds with other expenses.

This can lead to inconsistent stakes, poor decision-making, and difficulty in tracking profits.

• Solution: Set aside a specific amount as your matched betting bankroll—this could be as little as £50 to get started. Use only this bankroll for all matched betting activities, making it easy to track and grow over time.
• Pro tip: Using a separate bank account or e-wallet for matched betting can help keep personal and betting funds organised.
