How to bet on the spread college football?

When betting the spread for any sport, especially football, it is important to know the sport’s key numbers.
In both NFL and college football, games are usually decided by three points (a field goal) or seven points (a touchdown and extra point). So when shopping odds, the difference between -7 and -6.5 matters far more than the difference between -5 and 4.5
For most spread bets, the odds will be -110. This can vary depending on your bookmaker and the game you are betting on. If it is -110 odds and you bet $110, a win would yield a profit of $100. If you place a $115 bet on -115 odds, the profit would be $100, and so on.

It can be smart to use teasers — a parlay bet that uses modified spreads — while point-spread betting. In this instance, the spreads are moved in your favor, though you do need all matchups to win.

Another strategy for betting spreads is to shop around. If you’re seeing Patriots favored -7 everywhere you look but suddenly see one place offering a -6 at +EV (even) odds. This could be a smart value play against the market.
Lastly, you may want to consider buying half-points. This decreases your potential payout, but also decreases your risk. This method often could be the difference between a win or a loss, but obviously one should be cautious when purchasing points.
