Line‑Shopping in Sports Betting: How to Get the Edge (With Real‑World Examples)
When you first dip your toes into sports betting, the odds are often presented as a single, “official” line. In reality, every sportsbook has its own set of odds, and the difference can mean the difference between a break‑even wager and a win (or vice versa). That’s where line‑shopping comes in – a savvy bettor’s strategy for hunting the best odds across the market.
Below we break down what line‑shopping is, why it matters, and provide concrete examples from the NFL, NBA, MLB, and college football to illustrate how even small disparities can add up to significant edge over time.
1. What Is Line‑Shopping?
Line‑shopping is the practice of comparing the betting lines for a particular event across multiple sportsbooks to find the most favorable odds. In practice, this usually means:
| Bet Type | Odds Format | Example | How the Edge Works |
|---|---|---|---|
| Point Spread | “+3.5” vs. “+4.0” | Patriots +3.5 (DraftKings) vs. Patriots +4.0 (FanDuel) | The +4.0 line gives you a larger cushion; you’ll win the spread even if the Patriots lose by 3. |
| Moneyline | “-200” vs. “-190” | Lakers -200 (FanDuel) vs. Lakers -190 (BetMGM) | The -190 moneyline means you need to risk less for the same payout, giving you better ROI. |
| Over/Under | “45.5” vs. “46.0” | Over 45.5 (DraftKings) vs. Over 46.0 (FanDuel) | A lower over/under increases the probability of hitting the over. |
The key is to find the line that gives you the highest probability of winning or the lowest stake for a desired payoff.
2. Why It Matters: Small Margins, Big Gains
In sports betting, the “vig” or “juice” is typically around 10% (the odds are skewed to give the sportsbook a built‑in edge). If you consistently wager on the best available line, you effectively reduce the vig by a few points, which over thousands of bets can shift the expected value in your favor.
A quick math example:
- Standard line: –110 (you must bet $110 to win $100).
- Better line: –105 (you bet $105 to win $100).
That 5‑point difference means you lose less per bet, translating to a higher long‑term return.
3. Real‑World Examples
NFL: Patriots vs. Jets (Week 3, 2024)
| Sportsbook | Line | Example of a “good” line | Explanation |
|---|---|---|---|
| DraftKings | Patriots +3.5 | Patriots +3.5 | Standard line |
| FanDuel | Patriots +4.0 | Patriots +4.0 | Slightly better spread |
| BetMGM | Patriots +3.75 | Patriots +3.75 | Middle ground |
If you’re betting the Patriots to cover the spread, FanDuel’s +4.0 gives you an extra 0.5 win cushion. If the Patriots lose by 3, you still win the bet on FanDuel but lose on DraftKings.
NBA: Lakers vs. Clippers (Playoffs)
| Sportsbook | Moneyline | Example of a “good” line | Explanation |
|---|---|---|---|
| DraftKings | Lakers –200 | Lakers –200 | Standard line |
| FanDuel | Lakers –190 | Lakers –190 | Better value |
| BetMGM | Lakers –195 | Lakers –195 | Slightly better than DraftKings |
A -190 moneyline on FanDuel means you only need to wager $190 to win $100, instead of $200. For a $200 bet, you would win $105 on FanDuel instead of $100 on DraftKings.
MLB: Yankees vs. Red Sox (Regular Season)
| Sportsbook | Over/Under | Example | Why It Matters |
|---|---|---|---|
| DraftKings | 4.5 | 4.5 | Standard line |
| FanDuel | 4.0 | 4.0 | Lower over/under increases probability of hitting the over |
| BetMGM | 4.75 | 4.75 | Middle ground |
If you’re wagering the over (i.e., total runs), a lower 4.0 line means you win if the teams score 5 or more runs – a 3‑run game. A 4.5 line requires at least 5 runs but with less margin for error, so the 4.0 line is statistically better.
College Football: Alabama vs. LSU
| Sportsbook | Spread | Example | Benefit |
|---|---|---|---|
| DraftKings | Alabama +1.5 | Alabama +1.5 | Standard |
| FanDuel | Alabama +2.0 | Alabama +2.0 | Slightly better |
| BetMGM | Alabama +1.75 | Alabama +1.75 | Middle ground |
A +2.0 line for Alabama gives you a larger buffer if the game ends close. If Alabama loses by 1, you still win the bet on FanDuel.
4. How to Get Started with Line‑Shopping
- Choose a comparison site – Sites like OddsPortal, BetQL, or Sports Insights aggregate lines from all major sportsbooks in real time.
- Create accounts at multiple sportsbooks – Even if you only plan to bet at one, having multiple accounts allows you to place the same bet at the best line without leaving the comparison site.
- Track line movements – Lines shift as more money is placed. If you’re betting a big amount, watching the line move over the week can help you decide the optimal betting time.
- Use “middle” bets – When you can capture both sides of a spread, you can lock in a profit. For example, bet the over on FanDuel and the under on DraftKings; if the total runs is between the two lines, you win both bets.
- Keep a log – Note which sportsbook offered the best line for each bet and how often you win. This data helps refine your strategy.
5. Common Pitfalls and How to Avoid Them
| Pitfall | Why It Happens | Fix |
|---|---|---|
| Relying on a single sportsbook | Habit or lack of accounts | Open at least 2–3 sportsbooks to compare lines. |
| Ignoring the vig | Mistaking higher odds for better value | Compare the implied probability; a +10 line is not always better than a +9 if the vig is higher. |
| Betting too often on the same edge | Overconfidence after a streak | Diversify bets across different sports and bet types. |
| Not accounting for bonuses | Overlooking deposit or free‑bet offers | Factor in the effective cost of the bet if you’re using a bonus. |

Bottom Line

Whether you’re a casual fan placing a $20 wager on the next football game or a serious bettor looking to build a profitable edge, make line‑shopping a regular part of your routine. With a few minutes of comparison each week, you’ll be placing each bet with the highest possible value – and, ultimately, a higher chance of walking away a winner.
