What is advertising?
Advertising is any paid promotion of a product, service or idea meant to influence one or more people. It can take place on several mediums, such as print, radio, television and digital media. The main goal of advertising is to persuade someone to buy a project or perform an action.
Types of advertising
There are three main types of advertising, which are:
- Above the line: Above the line advertising is not targeted to a specific group and is created to reach large audiences. TV, radio and magazine advertisements are usually this type.
- Below the line: Below the line advertising is a type of advertisement that is directed toward a specific target audience. These can be mailing lists, in-store advertisements and commercials created for a specific program.
- Through the line: Through the line advertisement is often used for brand-building campaigns and has a mix of above and below the line techniques. They're usually widely distributed advertisements that use cookies or digital data to personalize the customer's experience.
Advertisements can also be sorted by their medium, such as television or print, or the type of technology they use, such as paid search or social media advertising.Read more: 14 Types of Advertising
10 reasons why advertising is important
Advertising is an important part of trade and commerce for multiple reasons, including:
Increases sales
Advertising's main goal is to increase the number of people who buy your product. You can achieve this by using advertisements to persuade customers that your product is high-quality, useful or desirable. An effective advertisement can convince customers to purchase your product, which may dramatically improve your overall sales.
Informs customers
Creating an advertisement is a simple way to inform potential customers of your product and any advantages or features it may have. You can include important information such as the function of a product, where you can buy it, price and unique qualities in a short period of time. Advertising also allows you to tell your audience about promotions such as sales, special services for new customers or special events.
Helps introduce products
When your company introduces a new product or service, you can create an ad to inform your customers about it. This allows you to show the new product to a large number of people and create an interest for the release. Telling a larger amount of people about your product release may increase the number of people who want to buy it.
Informs you about your competition
You can use advertisements to monitor your competition and learn about any developments they make. When a competitor releases a new product or feature, they may create an advertisement to inform their customers. This gives you the opportunity to develop something new of your own or create a new advertisement detailing the features of an existing product that addresses the same challenges.
Retains customers
Using advertising can help remind your customers about your brand and may encourage them to continue buying your product. A customer who once used your product may see an advertisement and remember their positive experience. This can motivate them to purchase that product again or try other services from your company.
Increases employee morale
An effective advertisement may improve the morale of coworkers who see or hear about it. People may find it easier to talk to potential customers about new products or services if the customer is already slightly aware of them. A quality advertisement may also increase a person's pride in their workplace.
Differentiates your brand
Because most products and services have multiple companies competing for customers, your company may need to find ways to distinguish itself from competitors. Advertising elements such as logos, color schemes, fonts and taglines are ways to establish a brand identity and create a difference between your product and other companies. If a customer recognizes or likes your brand design, that may increase the chances of them purchasing your product.
Increases customer trust
Advertisements can increase familiarity and trust between a company and its customers. If a potential customer sees multiple ads about your product, they may consider you a trusted brand. You can also use advertising to address any concerns, which further builds trust between your company and your customers.Related: How To Gain Customer Trust in 7 Steps
Reaches target customers
Using advertising can help you easily identify or market toward a particular target audience. After researching a target audience, you can release an ad that may appeal to them at locations they usually frequent. If you have more than one target audience, you can create separate ads and market to both audiences in different areas.
Explains company values
A company with powerful, visible values can resonate with customers and may encourage brand loyalty. Advertisement allows you to describe your company's core traits or values to a wide audience and may encourage them to try your product. Having clear company values can also increase customer trust and may strengthen a brand's identity.
Tips for effective advertising
Here are some suggestions for how to create effective advertising:
Attract the customer's attention
An engaging ad can help attract an audience and encourage them to continue interacting with the ad. Customers are more likely to remember or buy your product if an advertisement attracts their attention. Try to use techniques such as bright colors, jingles, sketches or clever taglines to interest potential viewers and keep their attention on your product or service.Related: 70 Advertisement Ideas for Your Business
Advocate for your product
An effective advertisement informs a customer about why they should purchase that item or service. Explain the benefits of your product and how it's different from your competitor's. Detailing the advantages of your item or service in an advertisement can help potential customers notice the benefits of your brand and may increase your sales.
Focus on your target audience
Understanding your target audience can help you create advertising that interests them and may increase your overall sales. Identify your target audience by reviewing sales history or demographic information about your customers or by distributing customer surveys. Then design advertising that appeals to them using research and focus groups.
Establish a consistent image
A consistent image helps potential customers easily identify your brand. It may also give them a feeling of familiarity which can increase the possibility of them buying your product. Consider creating a brand image by choosing similar colors, logos, images and general tone that you can use across your advertising materials.
Use powerful imagery
Powerful imagery can increase the chances of your audience remembering your advertisement. If a customer remembers your product, they may choose it over a competitor's when deciding on what to buy. Try to use powerful imagery in your ads such as clear descriptions, metaphors or interesting photos.Related: 32 Effective Advertising Tactics
Conduct research
Performing research can help you determine who uses your product and how to create more effective advertisements. Research allows you to identify target audiences, analyze your advertisement's reach, check the level of interaction with your ads and determine if your advertisement is increasing sales. Types of research include comparing profits before and after you release the ad, producing surveys and tracking the number of views on an advertisement.
Diversify your advertising
Reaching a wide audience can help you grow a customer base and may increase your sales. You can share your brand's message to a larger number of people by using different advertising techniques and mediums. Consider creating several different advertisements for various target audiences through different channels such as television or digital media.
Monitor your ads
After you release an advertisement to the public, you can monitor it to determine how well your audience responds. You can use focus groups, surveys and analytics tools to help measure the effectiveness of an advertisement. Once you have data about your ads, you can use it to modify your marketing strategy.
