The top 2 books are tightly clustered — only 0.00% separates them. The spread between #1 and #11 is 4.56% — book choice matters significantly for Serie B - Italy. Vig is trending up 0.24% since yesterday.
Serie B, Italy's second division, presents a distinctive betting landscape shaped by its competitive unpredictability and relatively lower market visibility compared to Serie A. The league features 20 teams playing a 38-match regular season, followed by promotion playoffs and relegation playouts, creating a compressed table where form swings are common. Scoring tends to be moderate — averaging around 2.4 to 2.7 goals per match in recent seasons — with a notable emphasis on defensive organization, particularly among mid-table sides. For bettors, this translates into frequent draws, tighter scorelines, and value opportunities in Asian handicap and under/over markets that mainstream bettors often overlook.
Bookmaker margins on Serie B matches tend to run wider than those on Serie A or top European leagues, typically ranging from 4% to 7% on 1X2 markets depending on the sportsbook and the profile of the fixture. High-profile matches — such as derbies or promotion-relevant clashes — attract more balanced action and sharper lines, while midweek fixtures or contests between lower-profile sides often carry inflated vig due to lower liquidity. This makes comparing margins across books particularly valuable in Serie B, where the difference between a sharp and soft line can be more pronounced than in higher-tier leagues.
The Serie B season runs from mid-August through mid-May, with playoffs extending into early June. Odds tend to be most competitive during the opening weeks — when bookmakers are still calibrating their models — and again in the final stretch, when promotion and relegation stakes sharpen public and sharp interest alike. Key factors influencing lines include home/away splits, which remain significant in Italian football's lower divisions where travel fatigue and hostile atmospheres matter, as well as squad depth, loan player availability (many clubs rely heavily on Serie A loanees), and managerial changes, which occur with remarkable frequency. Winter weather in northern Italian cities like Brescia and Bolzano can also affect pitch conditions and scoring, making situational awareness essential.

What is vig (vigorish) in sports betting?
Vig — short for vigorish, also called juice or overround — is the margin a sportsbook builds into its odds. It's the difference between the true probability of an outcome and what the odds imply. Lower vig means you keep more of your winnings on every bet. For example, a standard -110/-110 line has about 4.76% vig.
How often is this data updated?
We pull fresh odds from The Odds API three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds. The timestamp at the top of the page shows the most recent refresh.
How is the vig grade calculated?
Each sportsbook is graded on a letter scale based on average vig: A+ (under 2%) is exceptional, A (2–3%) is excellent, B+ (3–4%) is above average, B (4–5%) is the industry standard, C (5–6%) is below average, and D (above 6%) indicates high-juice markets.
Why does lower vig matter for bettors?
Lower vig directly impacts your long-term returns. A bettor placing $1,000 per week at a book with 4% vig loses roughly $40/week to the house edge. At 2% vig, that drops to $20/week — a $1,040 difference over a year. For serious bettors, shopping for lower vig is one of the most reliable ways to improve profitability.
What sportsbooks do you track?
We track both regulated US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars) and offshore books (Bovada, BetOnline, MyBookie, BetUS, LowVig.ag, BetAnySports). Data comes from The Odds API, which aggregates real-time lines from licensed sources.
How We Calculate These Numbers
- Data Source
- All odds on this page come from The Odds API, which aggregates real-time lines from licensed US and offshore sportsbooks. We track moneyline, spread, and totals markets across every sport with active betting lines.
- Update Frequency
- We pull a fresh snapshot of every tracked market three times per day — at 6:00 AM, 2:00 PM, and 10:00 PM UTC. Each snapshot captures the latest lines from every sportsbook that has posted odds for a given event. The timestamp at the top of each page tells you exactly when the data was last refreshed.
- Vig Calculation
- Vig (short for vigorish, also called juice or overround) measures the margin a sportsbook builds into its odds. We calculate it by converting the odds on each side of a market to implied probabilities, summing those probabilities, and subtracting 100%. For example, a market priced at -110/-110 implies 52.38% on each side — a total of 104.76%, meaning a vig of 4.76%. Lower vig means better value for bettors because you keep more of your winnings.
- Per-Market Breakdown
- We compute vig separately for each market type: moneyline (h2h), point spreads, and totals (over/under). The "average vig" shown for each sportsbook is the mean across all market types weighted by the number of events sampled in each market.
- Grading Scale
- Every sportsbook receives a letter grade based on its average vig: A+ (under 2%) is exceptional and rare — these are typically sharp-friendly books. A (2–3%) is excellent. B+ (3–4%) is above average. B (4–5%) is the industry standard for most recreational sportsbooks. C (5–6%) is below average. D (above 6%) indicates high-juice markets where bettors face a steep cost per wager.
- Trend Tracking
- We store daily snapshots for 30 days, allowing us to show 24-hour and 7-day vig trends. A downward trend (improving) means sportsbooks are tightening their lines — often in response to increased competition or higher betting volume as a season heats up.
