In an ongoing series of Lunch and Learn opportunities, the Southwest Gwinnett Chamber will host "The Biggest Digital Marketing Mistakes Small Business Owners Make" (and how to avoid them) 11:30 a.m. to 1 p.m. Tuesday, Sept. 15 at Courtyard by Marriot, 3209 Holcomb Bridge Road in Peachtree Corners.

At this Lunch and Learn, Cliff Tillery from Make It Loud will explore some of the most common marketing mistakes business owners make. Tillery will talk about how people go to extraordinary lengths to leave money on the table or worse, drive business to their competition.

Participants will learn how to avoid irritating prospects with digital marketing, how to identify "the good, the bad & the obvious", and the "basics" of how to break through the noise.

Admission is free for Southwest Gwinnett Chamber members. $15 for non-members. Registration: www.southwestgwinnettchamber.com.
