IMPORTANCE CHOICE CRITERIA AS A BASIS FOR TOURISM MARKET SEGMENTATION TECHNIQUES Ourania Vitouladiti Technological Educational Institute of Athens Faculty of Business Administration Department of Tourism Enterprises Athens, Greece Email: ranivito@hol.gr ABSTRACT This research paper aims to identify the most important criteria for a destination choice and to use these criteria as a basis for innovative market segmentation, necessary in today’s competitive environment. The above objectives are met through primary quantitative research with a representative sample of British tourists in Corfu. Cluster analysis techniques were performed in order to identify different clusters of criteria and segments. Seven bundles of important choice criteria and benefits were identified. Also five different segments, which revealed targeted marketing mix actions, were identified, based on importance choice criteria. Key words: Segmentation, benefit segmentation, importance choice criteria, cluster analysis, bundles of choice criteria 1. Introduction In our days, the traditional destinations, especially in the Mediterranean, face intense competition. There is a growing need for increased knowledge about tourist consumers’ motivations, needs and about influences on their decision making. One traditional Mediterranean destination is the island of Corfu. Tourism is considered the most important pillar of its economy. Germany and the UK are the leading generating markets from Europe. The island tourism offer, is mostly associated with the sun, sea and sand concept. This destination can be considered a miniature of the Greek tourism product. The island as an established destination faces intense competition and decreasing arrivals of its traditional markets. There is a need for insights in innovative segmentation techniques which allow improved knowledge on the demand side concerning possible changes in motives, wants and benefits sought. The use of the island, as a representative case study, for the implementation of primary research with a probability sample of British visitors (one of its basic markets) will enable the destination to explore its segments and to identify sub segments with different or changed needs and benefits sought in their holidays and as a result to improve communication on destination attributes that influence consumer behavior and loyalty. Segmentation techniques are the most used tools in order to improve this knowledge. There are a lot of ways of segmenting consumers. But as marketing increases in its sophistication the segmentation ways have to increase their intelligence. Apart from the traditional techniques of demographic, socioeconomic, geographic etc. characteristics which are very important variables, there is a segmentation technique that has attracted an increasing interest throughout the years, this of benefit segmentation. Benefit segmentation has long been considered an effective means of grouping tourists based on their attitudes towards services and products. In benefit segmentation tourists are characterized according to the benefits they seek from their purchases. Benefit segmentation is a market oriented approach consistent with the modern marketing concept (Lewis et al, 1995). It is considered that individuals perceive of products and services in terms of bundles of benefits or attributes (Kotler et all, 1996, Morgan, 1995). They buy a bundle of benefits (Mill and Morrisson, 1985). The relative importance of each benefit or attribute varies (Mayo and Jarvis, 1981). The likelihood of buying a product is determined by the extend to which the individuals perceive the product to contain sufficient benefits to satisfy their felt needs and also to the extend that the satisfaction of those felt needs are important to them (Mill and Morrisson, 1985). As Kotler (2000)suggests, knowledge of benefits searched by tourists let us know what to offer and promote in order to attract specific target markets. Identifying homogenous subsets of customers for particular geographic markets or linking particular product benefits for specific groups, allows managers to develop more strategically targeted products and campaigns (Dickman, 1999). The target markets, in order to be effective must be measurable, accessible, substantial, actionable and differentiable (Kotler et al, 2002). When the authorities in the private and public sector understand, in depth, tourist consumers’ characteristics and decision process then the promotional activities, price settings, planning and product development can be more consistent and effective. Therefore, this subdivision of tourists and potential tourists into useful groups is a critical step in building competitive advantages of a destination (Evans et all, 2003). As a result it is one of the most vital decisions a destination makes (Dolnicar, 2004). 2. Objectives of the study Therefore, the objectives of the study are: 1. 2. 3. 4. To identify the important benefits sought by the visitors of the island To identify bundles, or sets of benefits To determine segments of tourists based on the importance of benefits searched for in their holidays To offer marketing and management implications 3. Methodology 3.1. Research design - Sampling and data collection In order to achieve the targets of the study, it was necessary to carry out primary quantitative research. And in order to fulfill best the goals of the study the sample members (British) was decided to be first time visitors. The sample was decided to be stratified, because is probability sample and more representative. The island is divided into three areas, North, Central and South. Each area has all categories of hotels and accommodation. Since the boundaries of the areas were known, they were defined as strata. In every one of these strata, accommodation of every category was chosen by random sampling. The members of the sample were also chosen by random sampling in all the selected hotels and accommodation types. The final sample size obtained was 375 British first time visitors. This sample size (n=375) gives a statistical error (e≈5%) which is considered very satisfactory (level of significance α=0, 05, level of confidence 95%). This sample size and statistical error could permit the generalisation of results. 3.2. Questionnaire design – analysis The self administrated questionnaire comprised closed-end questions. The closed-end questions had a five-point rating scale. All the rating scales were labeled. Nineteen (19) variables concerning choice criteria or motives were listed. The final list of the variables was decided on the basis of their use in past studies focusing on island destination attributes (Beerli and Martin, 2004, Garcia et al, 2004). For the statistical analysis and the interpretation of the results the five-point scale of the questions was coded from 5 to 1, considering 5 the most important criterion and 1 the less important one, meaning the higher the score the more important the variable (5. very important, 4. quite important, 3. neither important nor unimportant, 2. quite unimportant, 1. very unimportant) .3.3. Profile and description of the sample Concerning the distribution of the sample by sex both sexes had an almost equal participation in the survey. Female respondents represented 57%, or 216 persons, male respondents represented 43%, or 160 persons out of a total of 376. Regarding age categories, 44% of the sample is between the ages of 35 and 54 years. The other age categories are equally represented with percentages of 27% for the under 34 age group and 29% for the 55+ group. This gives a balanced distribution. Distribution by income demonstrates expected percentages. The income brackets “>£20.000” and “£20.000 - £40.000” are represented equally (36% and 41% respectively). Their percentages are increased compared to the income bracket of “£40.000+”. This is an expected element which reassures the reliability of the sampling method, since it is known that the British market segment of Corfu belongs to the average income levels. .3.4. Statistical Analysis Firstly, this research paper used descriptive statistics in order to indicate the most important criteria. Secondly, hierarchical clustering analysis was undertaken to identify bundles of importance choice criteria and benefits. Thirdly, k-means clustering algorithm was applied to identify market segments based on their importance choice criteria when they choose a destination. Several cluster solutions were specified and the best cluster solutions were chosen on the basis that they offered the most meaningful, interpretable and distinguishable bundles and segments (Park and Yoon, 2009). 4. Data Analysis In table 1 the means of the five point scales are presented in descending order. The criteria which appear more important concern relaxing and services while as less important appear those regarding entertainment, adventure and extroversion. Nevertheless, it is observed that the means have high scores, 11 out of 19 criteria have mean >4, while only one criterion has mean < 3, which is the central point of the scale. This is a common phenomenon in rating scales that tends to create difficulties in discriminating among the more and less important criteria. In order to minimize this issue and clearly identify the differences, centered values for each one of the 19 criteria were structured. The new centered values reflect the differences among more and less important criteria and are considered as more appropriate for the analysis, being continuous variables. Table 1.

The between groups average linkage algorithm was the linkage method used and the measure of distance was the Pearson correlation coefficient. Seven new variables were revealed that will be named bundles. Each bundle is calculated as the mean score of the relevant attributes. The means of the bundles are presented in table 3. The more important appear to be the bundles relax and service and less important the bundles action and status. Table 2.

Differentiations of the mean scores of the bundles clearly discriminate into clusters. Also the demographic synthesis of segments differs (age, income, education level). This feature is a measure to the validity of the clustering. For the exploration of the segments both the 19 centered values as well as the original scale 5 - 1) were used. Methodologically, the task of naming the segments embodies a level of subjectivity. Table 5.

Results, comments and implications 5.1. Profile of segments and comments Segment 1 – Service oriented at a value The more sizable group, with 27% of respondents, comprises mostly from middle aged, middle class and average to low income vacationers, with secondary level education or higher technical education. They are very interested in service, relax and value for money, although they rate these clusters at the lower importance in comparison with the other segments. Segment 2 – Exploration, service and tranquility oriented A group that represents 18 % of respondents consists mainly of older vacationers, 55+, and together with segment 5 displays the higher percentages of university level and higher technical education. They usually have middle to high incomes. They are the most exploration oriented, they want to know and explore their vacation destination. Fun, action and status are low importance criteria for them. They are quiet, have little interest in sunbathing, seek tranquility and are interested in services. Segment 3 – Service, tranquility and nature oriented A segment that represents 17% of respondents consists mostly of middle age to older ages, 45 – 54 and 55+, displays high percentages of university level and higher technical education, together with segment 2 represent the more affluent segments of visitors. They seek tranquility more than the others, are the most service oriented, they consider the unspoiled physical environment and clean seas the more important criteria. Together with segment 2 they are interested in exploring the destination. Segment 4 – Fun and relaxation oriented at a budget This segment represents 21% of respondents, they consist mostly of younger vacationers, mostly under 34, and almost half of them, 47%, has lower/secondary education. They are considered working class youths, low income, budget bound, special offers seekers, probably the least loyal clientele. Their main goal is fun and relaxation with little interest in exploration and sport activities. However, the bundle of service is important for this segment as well. Segment 5 – Relaxation, sunbathing and activity oriented at a budget This segment represents18% of respondents, they consist mostly of younger vacationers, mostly under 34, and almost half of them, 41,8%, has University education. They are considered middle class youths, with a high percentage of university and college students, budget bound and special offers seekers but with a small interest to explore and possibly engage in some sport activity. 5.2. Discussion and marketing management implications From the above analysis specific conclusions emerge. Initially, the findings of this research paper, affirm the existence of the established markets, as it would be expected. Specifically segments 1, 4 and 5 that are considered the norm for Mediterranean destinations. At the same time this affirmation validates the reliability of the methodological approach. However, from the above description of these segments appears though, that this clientele has evolved in its lifestyle characteristics and demands and, as a result, in its priority criteria (such as service) while the prevailing view concerning these segments has remained the same over the decades, meaning simplistic, somewhat banal and stuck on the sea, sun and sand model. Moreover, the findings of this research paper revealed two new and distinct segments, namely 2 and 3. These two new segments comprise a substantial percentage of visitors (35%) who are the more affluent, well educated and clearly service oriented. Apart from these very interesting segmentation characteristics and high percentages, that make them a desirable target group, additional differences from the established markets are observed. Specifically, they rate as important benefits the exploration of their vacation destination, the nature and tranquility. The benefits of the typical Mediterranean model of the 3S are considered of less importance. The existence of this kind of segments is actually unknown, never targeted and approached through specific marketing efforts. In a similar fashion the evolved and differentiated characteristics of the classical markets remain unnoticed and therefore, have not been addressed by marketing mix variables. Last but not least, another rising issue is that of service, the bundle of which emerges among the most important criteria for all the identified segments. The findings of this study support the existing views which underline that improvements of education and welfare levels in Europeans countries have diversified the profiles of the consumers, their wants, motives and preferences and have increased the quality standard demanded (Poon, 1994). The findings and the revealed issues are of great importance because firstly, they can direct and enable destination marketers to combine the marketing mix variables in order to approach the new segments and satisfy the evolved demands of the classical clientele. Secondly, to best allocate the always restricted marketing budget in effective campaigns. This research was conducted in an established Greek destination using representative sample of a main tourist market. Replicating this study for other similar destinations within the Mediterranean could help to maximize the generalization of the findings. 6. Bibliography Beerli A, Martin JD. (2004).
