The best thing you do before posting your flyer, is to get permission from the person concerned.
Before posting a flyer anywhere, get permission from the concerned person. If you do that, your flyer remains there for quite a good period of time. If you go on posting it anywhere you wish to, it will be torn off within seconds, since people hate seeing bill boards at their property.
Analyse on the people you target, post them in places where they assemble in lots. Like supermarkets, restaurants, schools, colleges, offices, beauty parlous, saloons, theaters etc. Add a flyer to newspaper delivery service at your local area, or wherever you are capable to reach out to.
Place coupons or discounts or anything attractive in your flyer, that makes people not ignore your flyer. Keep it eye catching, rather flooding it with your prosperity. Place your brand name in big fonts, and possibly a logo of yours.
If your flyers are for a rummage sale, put them in places where lower income people are more likely to go... like thrift stores or the laundry mat or the lower income grocery store (like Aldi) or places people can entertain themselves for free or close to it... like the dog parks... the regular parks (in the bathroom pavilion is best) and also at local daycares... since people with kids often like to shop rummage sales for clothes and kid/baby gear.
To get more exposure for your business and to find potential new clients, you need to enlist your business in business directory listings. Being in the business directory not only enhances your search engine ranking, but it also opens door to more clients and visitors.
