Duplicate content or good tactic??

1. Use One Message: A high response rate ad usually conveys a single message. NordicTrack's message of the "World's Best Aerobic Exerciser" was simple and compelling. Your small business advertising needs to quickly communicate its core message in 3 seconds or less. If you are fearful and overwhelmed by technology, which computer book do you buy? "DOS for Dummies" began a best-selling phenomena because its message was easily understood and to the point.

2. Add Credibility: It has become human nature to distrust advertising. Claims need to be real and credible. Roy H. Williams, best-selling author of the "Wizard of Ads" says, "Any claim made in your advertising which your customer does not perceive as the truth is a horrible waste of ad dollars."

NordicTrack added enormous credibility from a University of Wisconsin-LaCrosse research study, ranking the cross-country ski exerciser first in the areas of weight loss, body fat reduction, and cardiovascular fitness. Ivory soap's advertising success was attributed to its credible statement that ivory soap is the 99-44/100% pure.

3. Test Everything: Large businesses have a greater margin to waste capital and resources without testing advertising. Small businesses do not have the luxury. Use coupons, codes, and specials to measure the headline, timing, and placement of your ad. Test only one item at a time and one medium. Testing can be as simple as asking every customer for several weeks how they heard of your business.

4. Be Easy to Contact: Every single brochure, box, email and all company literature should have full contact information including: website and email address, phone and fax numbers, and company address. It seems simple but is forgotten by most companies. At NordicTrack, every box a ski machine went into had full contact information and the "World's Best Aerobic Exerciser" tagline. Be everywhere.

5. Match Ads to Target: Successful business advertising speaks to one target market only. At NordicTrack, the ads were tailored to each market. An ad in a medical publication preached the cardio-vascular benefits of cross-country skiing to heart patients. Ads in women's magazines discussed the weight-loss and calorie burn from cross-country skiing. Focus the message to the target group.

I have noticed a lot of my competitors are using a certain tactic to rank for there local towns etc.

They have multiple pages, with the same text (except for the place names in the text have been changed) but different titles, tags, description etc, because the text is the same is this not classed as duplicate content?
