Guerrilla marketing was originally a marketing strategy in which low-cost, unconventional means (including the use of graffiti, sticker bombing, flyer posting, etc.) were used in a (generally) localized fashion to draw attention to an idea, product, or service. Some large companies use unconventional advertisement techniques, proclaiming to be guerrilla marketing but those companies will have larger budget and the brand is already visible. Today, guerrilla marketing may also include promotion through a network of individuals, groups, or organizations working to popularize a product or idea by use of such strategies as flash mobs, viral marketing campaigns, or internet marketing. The main point of guerrilla marketing is that the activities are done exclusively on the streets or other public places, such as shopping centers, parks or beaches with maximum people access so as to attract much audience. The different types of guerrilla marketing are: Ambient, Ambush, Stealth, viral and the new concept called Street Marketing, coined by Dr. Marcel Saucet, Professor at University of San Diego and Harvard case study lecturer in his book Street Marketing TM, in 2013.
The term "guerrilla marketing" is traced to guerrilla warfare, which employs atypical tactics to achieve an objective.
Guerrilla marketing was initially used by small and medium-sized businesses, but it is increasingly being adopted by big business. The concept of guerrilla marketing rises from an unconventional system of promotion that relies on patience, energy, and imagination rather than a big advertising budget. Typically, guerrilla marketing campaigns are unexpected and unconventional, potentially interactive, with consumers targeted in unexpected places. The objective of guerrilla marketing is to create a unique, engaging, and thought-provoking concept to generate buzz.It involves high imagination and energy to execute a guerrilla marketing campaign. This kind of marketing is purely focusing on taking the consumer by surprise, creating a greater impression and eventually leading to buzz through word-of-mouth or social media platforms. Guerrilla marketing involves unusual approaches to advertising, such as targeted promotional-driven encounters in public places, street giveaways of products, PR stunts, flash-mob presentations, or any unconventional marketing intended to get results and create a memorable brand experience. Modern approaches to guerrilla marketing often utilize mobile-digital technologies. This enables advertisers to engage consumers emotionally, and often enough, to hopefully cause a campaign to turn viral, thereby realizing maximum returns on a relatively low initial investment. As a result, the concept of street marketing was born. It has evolved from being only the application of activities on the streets, to be the development of innovative practices of promotion. For example, one method used by many enterprises to promote their products or services on the streets is the distribution of fliers. This activity does not focus on creativity, but on making publicity on the streets. However, with the passage of time, companies have developed more unconventional techniques to catch the attention of the clients. The difficulty with marketing campaign is to plan, organize and execute the operation. The agencies or advertisers will always have to identify a unique and creative idea, integrate the message required by the advertisers in the operation in such a way that most of the target audience understands it clearly and has the potential to get it viral. If the campaign’s intent is vague or abstract, the viewers will fail to notice the effect and the message.
Guerrilla vs Street Marketing
Street marketing is a subset of guerrilla marketing. Like guerrilla marketing, street marketing has the characteristic of being unconventional. However, it is limited to the streets or public places. Other forms of guerrilla marketing use other media and processes, such as the Internet, to establish communication with the customers.
Guerrilla marketing is indeed being understood more and more as mobilizing not only the space of the streets but also the imagination of the street: that of street culture and street art. The Y generation, broadly consisting of young urbanites (15 – 30 years old), is often put forth as the most susceptible target for the campaigns due to its associations with the culture of the street. The success on any guerrilla marketing campaign lies on the relationship between advertiser and the agency. Both parties will have feel the need and work on it with same goals. The desire for instant gratification of internet users provides an avenue for guerrilla marketing by allowing businesses to combine wait marketing with guerrilla tactics. Simple examples consist of using 'loading' pages or image alt texts to display an entertaining or informative message to users waiting to access the content they were trying to get to. As users dislike waiting with no occupation on the web, it is essential, and easy, to capture their attention this way. Other website methods include interesting web features such as engaging landing pages.
Street marketing, unlike traditional media like usual flyers or billboards, uses different techniques trying to get engaged with the target audience. This was born when companies wanted to take steps to make customers attracted to the brand rather than waiting for them to come. This was especially the case with small and medium businesses. Levinson, in 1984 mentioned that the guerrilla marketing can be executed in the street but street marketing itself was coined by Saucet in 2013. The different types of street marketing types, according to the model of Cova and Saucet are: Street/ Ambient; Ambush/ Parasitic; Stealth/ undercover; Viral / Buzz. The difficulty with marketing campaign is to plan, organize and execute the operation. The agencies or advertisers will always have to identify a unique and creative idea, integrate the message required by the advertisers in the operation in such a way that most of the target audience understands it clearly and has the potential to get it viral. If the campaign’s intent is vague or abstract, the viewers will fail to notice the effect and the message.
The guerrilla marketing promotion strategy was first identified by Jay Conrad Levinson in his book Guerrilla Marketing (1984). The book describes hundreds of "guerrilla marketing weapons" in use at the time. Guerrilla marketers need to be creative in devising unconventional methods of promotion to maintain the public's interest in a product or service. Levinson writes that when implementing guerrilla marketing tactics, smaller organizations and entrepreneurs are actually at an advantage. Ultimately, however, guerrilla marketers must "deliver the goods." In The Guerrilla Marketing Handbook, the authors write: "...in order to sell a product or a service, a company must establish a relationship with the customer. It must build trust and support the customer's needs, and it must provide a product that delivers the promised benefits...". The different strategies of guerrilla marketing are: Ambient Marketing: Ambient communication is a complex form of corporate communication that uses elements of the environment, including nearly every available physical surface, to convey messages that elicit customer engagement. It is a compile of intelligence, flexibility and effective use of the atmosphere. Ambush Marketing: Ambush marketing is a form of associative marketing, utilized by an organization to capitalize upon the awareness, attention, goodwill, and other benefits, generated by having an association with an event or property, without that organization having an official or direct connection to that event or property. Stealth Marketing: Stealth marketing is a deliberate act of entering, operating in, or exiting a market in a furtive, secretive or imperceptible manner, or an attempt to do so. People get involved with the product without them actually knowing that they are the part of advertisement campaign. This needs to be done very carefully because if the participants are made aware of the campaign, it will have a negative effect on the brand. Viral Marketing: Viral marketing describes any strategy that encourages individuals to pass on a marketing message to others, creating the potential for exponential growth in the message’s exposure and influence. Like viruses, such strategies take advantage of rapid multiplication to explode the message to thousands, to millions. Off the Internet, viral marketing has been referred to as "word-of-mouth," "creating a buzz," "leveraging the media," "network marketing." But on the Internet, for better or worse, it’s called "viral marketing." While others smarter than I have attempted to rename it, to somehow domesticate and tame it, I won’t try. The term "viral marketing" has stuck.
- Street Marketing: According to Marcel Saucet and Bernard Cova, Street Marketing™ can be used as a general term encompassing six principal types of activities:
- Distribution of flyers or products This activity is more traditional and the most common form of street marketing employed by brands.
- Product animations This form of operation consists of personalizing a high-traffic space using brand imagery. The idea is to create a micro-universe in order to promote a new product or service.
- Human animations The goal of such actions is to create a space in which the brand’s message is communicated through human activity.
- Road shows This form of mobile presentation is based on the development of means of transport: Taxi, bike, Segway, etc.
- Uncovered actions These activities involve the customization of street elements.
- Event actions These activities take the form of spectacles, such as flash mobs or contests. The idea is to promote a product, service or brand value through organization of a public event.
Online Guerilla Marketing
The web is rife with examples of guerrilla marketing, to the extent that many of us don't notice its presence - until a particularly successful campaign arises. The desire for instant gratification of internet users provides an avenue for guerrilla marketing by allowing businesses to combine wait marketing with guerrilla tactics. Simple examples consist of using 'loading' pages or image alt texts to display an entertaining or informative message to users waiting to access the content they were trying to get to. As users dislike waiting with no occupation on the web, it is essential, and easy, to capture their attention this way. Other website methods include interesting web features such as engaging landing pages.
Many online marketing strategies also use social media such as Facebook and LinkedIn to begin campaigns, shareable features and event host events. Other companies run competitions or discounts based on encouraging users to share or create content related to their product. Viral videos are an incredibly popular form of guerrilla marketing in which companies film entertaining or surprising videos that internet users are likely to share and enjoy, that subtly advertise their service or product. Some companies such as Google even create interactive elements like the themed Google logo games to spark interest and engagement. These dynamic guerrilla marking tactics can become news globally and give businesses considerable publicity.
Associated marketing trends
The term, guerrilla marketing, is now often used more loosely as a descriptor for the use of non-traditional media, such as or street art, graffiti (or "reverse graffiti"), flyer-posting, ambush marketing, and forehead advertising. It may also be a strong component of promotions involving associated strategies, such as:
- Grassroots marketing and astroturfing—disguising company messaging as an authentic grassroots movement;
- Street or "tissue pack" marketing—hand-to-hand marketing;
- Wait marketing—presented when and where consumers are waiting (such as medical offices, urinals, or gas pumps).
- Internet marketing—having presence on sites, subliminally encouraging its users (thereby creating "buzz" through a combination of viral and undercover marketing);
- Viral marketing—through social networks.
- Publicity stunts- A publicity stunt is defined as a pre-planned event that is designed to attract the public’s eye and attention, to create hype about that topic, event or service.
Undercover marketing (also known as "stealth marketing", or, by its detractors, "roach baiting") is where consumers do not realize they are being marketed to. Buzz campaigns can reach consumers isolated from all other media, and unlike conventional media, consumers tend to trust it more often, as it is usually coming from a friend or acquaintance. Overall, the person doing the marketing must look and sound like a peer of their target audience, without any signs of an ulterior motive for endorsing the item.
Sony Ericsson used an undercover campaign in 2002 when they hired 60 actors in ten major cities and had them accost strangers and ask them: "Would you mind taking my picture?" The actor then handed the target a brand new picture phone while talking about how cool the new device was. "And thus an act of civility was converted into a branding event. Other examples and blogs can be found at streetandmarketing website 
First, enterprises identify the public places where the campaign can be developed such as beaches, cultural events, close to schools, sporting events and recreation centers for children. Next, companies have to develop a plan to get close to different media and the target market. In order to attract attention, street marketing events not only involve unusual activities, but use technology as part of the events. The purpose is to increase the value of the campaigns and get potential consumers' attention. Besides, the plans that companies develop take into account that guerrilla or street marketing involves global communication and interaction not only with the customers or the media. They are also developed to identify opportunities and collect enough information about products, markets and competitors. For example, for business it is important that customers stay with them, instead of choosing the competitors’ offers. They implement innovative strategies with which they will not lose position in the market, and they consider supplementation with other advertisement through other mediums, such as radio and television, when using street marketing. There are various examples of strategies that are used in guerrilla marketing. One of them is to provide offers to increase sales. In many cases, businesses do not only supply their products or services to be recognized, but they also offer other things for free. Another instance is to present a fundraiser offer. The point of this strategy is to help other organizations, such as schools, by offering them money. Most companies implement this method not only to increase their sales, but to improve their reputation and image among the community. Finally, there is a strategy called "team selling" that consists of conforming groups of people, the majority of them young, who go knocking the doors of different houses in a neighborhood. They do this in order to help companies promoting and selling their products or services. When doing guerrilla marketing or street marketing, organizations also consider focusing on the psychological approach. For many companies, this implies if they are having success or not. Street marketing focuses on some psychological aspects to know costumers' behavior and preferences. For example, certain psychological areas study how people’s brains are divided: 45% of people are left-brained, 45% are right brained, and 10% are balanced. Left-brained persons tend to be logical, right-brained ones tend to be emotional, and the rest combine the two. Then, according to the product or service that enterprises provide, and also the kind of costumer, businesses decides the way they are going to manage their street marketing campaigns. Besides, almost all the enterprises base their street marketing campaigns on repeating the messages they spread among their customers. Repetition is related to the unconscious part of the mind. This is the one in charge of making decisions. It lets people know what they are going to choose, as well as what they are going to buy. Businesses follow the principle that establishes that, the more people paying attention to the campaign, the more possibilities that campaign has for being remembered. When a company decides to do a guerrilla marketing campaign which could be anything out of viral, ambient, ambush, street or stealth, the focus for them is to meet the objectives. The main objectives for them are:
- To create enough buzz to serve in word-of-mouth, helping the brand to establish well with its products.
- To touch most of the five sensory identities of the customer/consumer enhancing personal experience with the brand and building good reputation.
- To reach the target successfully by taking the brand to them in their daily routine.
Through the experience and the ephemeral feelings shared between the company and the target, advertisers and agencies generate a feeling of intimacy that resonates beyond the encounter. This feeling of nearness becomes all the more lasting as the affected individuals relive this encounter on the internet through social media.
Outcome of a Campaign
After the execution of the guerrilla marketing campaign, it could raise positive or a negative outcome.
Positive As stated above, a guerrilla marketing involves low budget creating high impact on consumers mind. The effect is explained by Huttler and Hoffman, 2011. As the model explains, the three different effects that are expected are: Surprise, Diffusion and Low cost effect.
- Surprise effect: To have the element of surprise, companies tend to use street or ambient marketing techniques. These two types of guerrilla marketing techniques follow by placing unusual objects which are relatively large or small to grasp attention. They are classic example for outdoor marketing during hours where the targets are easy to find.
- Diffusion effect: This is to get the marketing viral. A campaign making the consumers getting involved and happy will reflect on spreading the message and sharing the experience through word-of-mouth or consumers shooting videos and taking pictures of the operation and sharing them through social networking platforms. This kind of effect is automatically generated without any further cost incurred to the advertisers.
- Low cost effect: Ambush and stealth marketing techniques come under low cost effect . For instance, using a big event to promote the brand but without getting directly involved with the event. For example, the brand ‘Beats’ ambush marketing during the London, 2012 Olympics which gave free headphones to Olympic competitors months before the game and getting them involved in marketing campaign without their knowledge.
Negative Guerrilla marketing creates more attention and the customers are engaged to the campaign with most of the time active participation in the brand’s campaign. Some campaigns could create negative effects on consumers with various factors such as ethical, values, believes or obstructing the way. These could result in unexpected and unwanted negative reactions from the consumers. Advertisers and agencies will have to consider all options before executing a campaign to avoid mishaps. The last thing any advertisers will want from a marketing operation is consumers getting irritated, sad, hurt or filing a lawsuit with any particular factor.
Because of the nature of guerrilla marketing, the message and objective must be clearly defined in order to avoid being misunderstood. Misinterpretation by the targeted audience of the message intended to be promoted is a risk. Word-of-mouth advertising does not always stay focused enough to present the intended message. The rumor-like spread of word-of-mouth marketing is uncontrollable once released, and can result in a misrepresentation of the message or confusion about a brand.
Another risk involves wrongly timed (or wrongly placed) events, which may actually be perceived to be against the interests of the consumer. For instance, in an ill-conceived promotion which took place on January 31, 2007, several magnetic circuit boards—each with an flashing LED cartoon figure—were attached to metal surfaces in and around Boston, Massachusetts to promote the animated series, Aqua Teen Hunger Force. The circuit boards were mistakenly taken for explosive devices. Several subway stations; bridges; and a portion of Interstate 93 were closed as police examined, removed, and (in some cases) destroyed the devices.
Some guerrilla marketing may incite the ire of local authorities. Then risks are assessed and may still be considered worthwhile. Such was the case in Houston, Texas, when BMW Auto's ad agency, Street Factory Media, attached a replica of a Mini-Cooper (made of Styrofoam), to the side of a downtown building in January 2013. For the small cost of a city-issued fine, the company received front page advertising in the Houston Chronicle. Street art is thus a subversive activity, hijacking public places and inventing rather paradoxical forms of expression that reformulate ways of communicating (Borghini et al. 2010; Visconti et al. 2010), all of which inform street marketing practices. Thus marketing in the street, given that it is inspired by the work of such artists, brings with it constraints and statutory risks for which agencies and advertisers are generally not prepared (West and Ford 2001). The main problem is that, by definition, street mobilization campaigns require the use of public space, and that use must be authorized by government authorities to be legal. This is just as true for simple operations like distributing flyers as it is for mobilizing products or people and, of course, for a disguised campaign. The authorizations necessary to carry out such a campaign are often very difficult to obtain within the time allotted for bringing the plan to fruition. Numerous potential operations have failed to obtain authorization for safety reasons, and in certain urban areas it is even expressly forbidden to undertake a guerrilla marketing campaign. In such cases, many agencies and advertisers will simply go ahead with the operation, meaning that they choose to act without authorization. How is such a choice reached, and on what bases? How is it justified? What impact does this choice have on the performance and costs of the operation? What transformations does this choice bring to the agency–advertiser relationship? These are the main questions posed in the development of street marketing operations today.
Another problem presents itself if marketers fail to properly execute an undercover campaign. They run considerable risk of backlash. An example of this can be found in Sony Entertainment's on-line debacle with Zipatoni. The company attempted to promote Zipatoni through a stealth marketing campaign, which was quickly detected by the internet community, resulting in Sony immediately experiencing a backlash from video game enthusiasts.
