McDonald's strong run as of late continued for the fast-food giant in July, with global same-store sales increasing 5.1 percent, the company said Monday.

McDonald's has been outperforming competitors with strong global same-store sales growth, one of the key factors investors use to determine success in the industry.

Fueled by competitive pricing during the recession and healthy and diversified menu additions McDonald's has been delivering results in its regions around the world.

The company had project global same-store sales growth of between four percent and five person in July, slightly down from June's 7.7 same-stores sales increase. So the 5.1 percent result was ahead of company guidance.

Same-stores are those open for more than a year.

Same-store sales in the U.S. rose 4.4 percent in July, McDonald's said, fueled by popularity of the company's McCafe beverages.

McDonald's launched its McCafe coffee and specialty drinks line in stores in 2009, and that's been a consistent driver of higher sales traffic.

In Europe, McDonald's same-store sales rose 5.3 percent, based on strong performance in the U.K., Russia and Germany.

In the Asia/Pacific, Middle East and Africa, McDonald's stores posted a four percent increase.

McDonald's said in June its second-quarter net income rose 15 percent.
