Building Brand and Trust Leads to Purchase Intention

Chapter 1: Introduction to Brand Trust and Purchase Intention

An overview of the research study is provided in this introductory chapter, which outlines the background, goals, scope, problem justification, research questions, significance, constraints, structure, and definitions of key terms.

1.1 Introduction

Social media influencer marketing (SMIM), as defined by Gurrieri et al. (2024), is a digital advertising strategy where companies collaborate with social media influencers to promote products through relatable, authentic content. According to Ilavarasan et al. (2018), this approach leverages the trustworthiness and specialized knowledge of online opinion leaders to shape consumer behavior. Djafarova and Bowes (2021) further emphasize that influencer marketing serves as a direct conduit between audiences and businesses, prioritizing building brand and trust through individualized recommendations rather than conventional advertising.

Studies demonstrate that SMIM significantly influences customer purchasing decisions. Research by Kim (2021) suggests that SMIM exerts a positive and significant effect on consumer purchase intentions. In the highly competitive apparel sector, consumer decision-making relies heavily on brand trust. Consumers exhibit a strong tendency to buy products recommended by their preferred social media influencers. For businesses executing digital campaigns, comprehending how SMIM affects customer purchase intention and the underlying process of building brand and trust in the Pakistani apparel market is crucial for driving sales and profitability.

While elements like brand love (Goswami & Balasubramanian, 2022), brand image (Danes et al., 2012), and brand advocacy (Rosário & Casaca, 2025) influence purchase intentions globally, it remains unclear how these characteristics uniquely affect Pakistani consumers. Therefore, this study investigates how SMIM affects consumer purchase intention in the Pakistani clothing market through the mediating role of brand trust, offering insights into how businesses can optimize their market position.

1.2 Research Objectives

The primary goal of this study is to look into how social media influencer marketing affects customer purchasing decisions in the domestic fashion market. Specially, this study seeks:

• To investigate the factors contributing to SMIM efficacy in the Pakistani apparel industry.
• To evaluate the impact of SMIM on purchase intention among Pakistani apparel consumers.
• To identify the role of brand trust as a mediator in the relationship between SMIM and purchase intention.
• To provide actionable strategies for businesses focused on building brand and trust via digital channels.

1.3 Scope of Research

The scope of this research is bounded by the impact of SMIM on purchase intention within the Pakistani apparel industry. The study focuses on literature and secondary data representing Pakistani consumers who have purchased apparel based on influencer recommendations. The research examines how brand trust mediates the relationship between consumer purchase intention and SMIM variables (including perceptions, attitudes, and behaviors).

The analysis focuses on the Pakistani apparel industry, one of the most competitive and dynamic sectors of the national economy. The sector has undergone significant structural changes due to technological advancements, shifting consumer preferences, and increased competition from e-commerce retailers. In Fiscal Year 2020–21, Pakistan’s textile and clothing exports increased 22.94% to $15.4 billion. Therefore, this research provides valuable insights into how SMIM can be leveraged to influence consumer behavior while building brand and trust in a hyper-competitive landscape.

1.4 Research Questions

The following research questions guide this study:

• How does SMIM contribute to purchase intention in the Pakistani apparel industry?
• How does brand trust impact purchase intention among Pakistani apparel consumers?
• What is the mediating role of brand trust in the relationship between SMIM and purchase intention within the Pakistani apparel industry?

1.5 Significance of Research

Understanding consumer behavior in the Pakistani garment sector is critical, as it contributes significantly to the national GDP. For businesses to remain profitable, recognizing the factors that drive purchase intention is essential. Because consumers use fashion brands to express their identities and values, branding has become increasingly vital. Consequently, organizations must master the mechanics of building brand and trust to develop marketing strategies that resonate with their target demographics.

Additionally, this study adds to the academic body of knowledge on digital branding and consumer behavior in developing South Asian economies. By examining the psychological processes underlying consumer decision-making, this study sheds light on how customers in Pakistan’s clothing market use SMIM and brand trust as indicators of status, price, and quality.

1.6 Research Gap

Despite the expansion of global research on digital marketing, several critical gaps persist:

• There is a lack of comprehensive research on influencer marketing specifically tailored to Pakistan’s apparel sector.
• An absence of bibliometric mapping detailing how SMIM targets the purchase intentions of Pakistani consumers.
• Few empirical frameworks evaluate how the synergy between SMIM and purchase intention assists local brands in building brand and trust.
• There is a broad opening for research exploring the underlying psychological mechanisms that convert influencer engagement into long-term brand equity.

1.7 Research Limitations

While this study advances the understanding of consumer choices, it possesses structural limitations. Firstly, it relies entirely on secondary data and systematic literature review methodologies; it does not collect primary empirical data. Future studies could expand these findings by gathering primary data via consumer surveys, structural equation modeling (SEM), or focus groups. Secondly, this study focuses primarily on brand trust and purchase intention as key outcomes. Future research should integrate other key constructs such as brand loyalty, brand image, and active customer engagement to evaluate the full scope of building brand and trust online.

1.8 Research Structure

The five separate chapters making up this research study each serve a distinct function in examining how SMIM affects purchase intention through brand trust.

1.9 Key Terms and Definitions

• Social Media Influencer Marketing (SMIM): A digital advertising approach where companies work with social media influencers to promote products through relatable, authentic content (Gurrieri et al., 2024).
• Brand Trust: Customers’ perceptions of a brand’s skills, effectiveness, and performance, resulting in the expectation of reliable quality (Chaudhuri & Holbrook, 2001).
• Purchase Intention: The deliberate willingness or plan of a consumer to purchase a specific product or service (Cuong, 2020).

Chapter 2: Literature Review

This chapter provides an overview of the variables constructed in the research model: Social Media Influencer Marketing (SMIM), Brand Trust, and Purchase Intention. It contextualizes the Pakistani clothing industry, examines underlying theoretical frameworks, and analyzes empirical viewpoints regarding digital consumer behavior.

2.1 Introduction

2.1.1 Overview of the Pakistani Clothing Industry

The Pakistani apparel sector is the foundation of the country’s manufacturing economy, serving as a primary source of employment and foreign income. According to industry data from Statista (2024), it is one of Pakistan’s fastest-growing sectors, employing over 25 million people directly or indirectly and contributing roughly 8.5% to the national GDP. Pakistan stands as the world’s fourth-largest producer of cotton and Asia’s eighth-largest exporter of textiles. It encompasses a complete textile value chain—from raw cotton production and spinning to final garment manufacturing. This local availability of raw materials lowers production costs and shortens operational lead times.

In the contemporary retail market, local brands fiercely compete for consumer attention. Due to advancements in digital exposure and literacy, Pakistani consumers are increasingly informed when making purchases (Liu & Chang, 2017). The most prominent apparel brands in the country include Khaadi, Gul Ahmed, Sapphire, Nishat Linen, Junaid Jamshed (J.), Alkaram Studio, Maria.B, Bonanza Satrangi, and Limelight. These enterprises maintain dominance through extensive retail footprints and digital execution. Affordability, quality, cultural style, and brand reputation heavily impact their market share (Asghar et al., 2024). For these market players, sustainable growth depends on successfully building brand and trust among a digitally connected consumer base.

2.1.2 Significance of SMIM

Social media influencers have shifted from peripheral content creators to core brand ambassadors. In this study, SMIM efficacy is conceptualized through personality traits and content quality, both of which drive consumer choice imitation (Chan, 2023). Existing literature suggests that individuals draw style and purchasing inspiration from online personalities with whom they perceive a close, authentic connection.

Consequently, customer loyalty rises when the perceived distance between the Social Media Influencer (SMI) and the consumer decreases. This dynamic is driven by interactivity. According to Burgoon et al. (1999), interactivity is the degree to which a person feels involved in a mediated encounter. Social media platforms facilitate real-time, two-way communication. When influencers respond to comments or share behind-the-scenes content, consumers experience enhanced social attachment. This perceived interaction serves as a primary driver for building brand and trust, which directly increases the probability of consumer purchase actions.

2.2 Theoretical and Conceptual Framework

2.2.1 Conceptualization of SMIM and Brand Trust

Influencer marketing relies on consumer trust. Purchase intentions are heavily influenced by perceived trustworthiness, especially during product endorsements. According to Freberg et al. (2011), customers trust products endorsed by influencers they perceive as open, honest, and independent. Veckalne et al. (2025) note that consumers’ opinions of a brand improve when the sponsoring influencer is regarded as genuine. This is vital in the fashion and beauty sectors, where consumers look for personalized style suggestions that match their self-image. For this study, the primary dimensions of influencer marketing are identified as:

• Credibility: Comprising attractiveness, expertise, and trustworthiness (Bhatt et al., 2023). Consumers believe influencers who display domain authority and transparency (Djafarova & Bowes, 2021).
• Content Quality: The visual and practical appeal of postings, ensuring they are unique, creative, and contextually relevant within crowded online feeds.
• Reach: The audience size an influencer commands, categorizing macro-influencers (broad visibility) and micro-influencers (highly engaged niche audiences) (De Veirman et al., 2017).
• Authenticity: Sincere, unvarnished communication reflecting actual product experiences, which minimizes consumer skepticism (Marwick, 2013).

2.2.2 Conceptual Comparison: SMIM vs. Brand Trust

2.2.3 Defining Brand Trust

Brand trust is the customer’s belief that a brand will consistently meet their needs and deliver a reliable, high-quality experience (Chaudhuri & Holbrook, 2001). Literature indicates that trust is grounded in the expectation that a company will act in the consumer’s best interest and avoid exploitation, particularly in digital environments characterized by transactional uncertainty. Brand trust forms an emotional bond that influences repeat patronage. Consistent product quality, effective customer service, and transparent communication are long-established factors in fostering this bond. In the digital era, influencers have emerged as critical intermediaries, shifting the processes of building brand and trust into collaborative spaces where consumer trust is shared between the product and the endorser.

2.2.4 Key Drivers of Brand Trust

In the era of social media marketing, the process of building brand and trust is governed by four foundational pillars:

• Consistency: Consistency in product quality and brand messaging forms the basis of trust. In influencer marketing, alignment between the influencer’s personal lifestyle and the brand’s core values is essential. A disconnect can reduce trust in both parties.
• Transparency: This refers to open communication regarding operations, sourcing, and commercial terms. In digital marketing, explicit disclosure of sponsored partnerships satisfies consumer demand for honesty and enhances institutional expertise perceptions.
• Emotional Connection: Trust is both cognitive and affective. Consumers trust companies that share their values or social outlooks. Relatable influencers can build an emotional connection with their audience, transferring that goodwill to the sponsored brand.
• Social Proof: Peer reviews, user-generated testimonials, and influencer endorsements provide public validation of a brand’s quality, lowering perceived purchasing risk.

2.2.5 Mediating Role of Brand Trust

While SMIM is a powerful tool in contemporary advertising, it carries the risk of appearing inauthentic if over-commercialized. Brands leverage influencer reach to scale their audience, but literature underscores that reach alone does not guarantee sales conversions. Brand trust serves as the central mediating variable that translates influencer engagement into actual purchase intentions (Gökerik, 2024). Within the Pakistani apparel sector, effective influencer campaigns must first succeed in building brand and trust before they can reliably shift consumer purchase intentions.

2.2.6 Defining Purchase Intention

Purchase intention is an individual’s deliberate plan to execute a buying behavior, shaped by personal attitudes and perceived social norms (Brakus et al., 2009). Rooted in the Theory of Planned Behavior (TPB), this concept treats cognitive assessments of product utility and emotional reactions to marketing stimuli as direct predictors of actual behavior (Bosnjak et al., 2020). Dodds et al. (1991) emphasize that purchase intention reflects perceived value—balancing evaluations of price, quality, and reputation. Higher perceived value reduces transaction risk, thereby increasing the likelihood of purchase.

In the digital age, purchase intention is shaped by online interactions and social proof (Tiago & Veríssimo, 2014). Content creators drive this process by aligning narrative messaging with consumer identity goals, transforming purchase intention from a cold calculation into a trust-based emotional commitment (Chetioui et al., 2020).

2.3 Theoretical Framework Alignment

This study is supported by three primary theories: Social Influence Theory, the Elaboration Likelihood Model (ELM), and Parasocial Interaction (PSI) Theory.

• Social Influence Theory: Posits that individuals adopt the behaviors or attitudes of people they perceive as authoritative or credible. In digital marketing, this explains why consumers follow recommendations from influencers who display expertise and authenticity.
• Elaboration Likelihood Model (ELM): Clarifies how consumers process persuasive messages. In fast-paced digital settings, consumers often rely on the peripheral route, using surface cues like an influencer’s attractiveness or follower count. However, when content quality is high and highly relevant, the central route is triggered, leading to longer-lasting attitude adjustments.
• Parasocial Interaction (PSI) Theory: Explains the psychological, one-sided bonds that social media users develop with content creators, viewing them as reliable peers.

Combined, these theories explain how Pakistani consumers navigate the fashion market. Local consumers often look to influencers as cultural guides to help verify product quality and authenticity in an ecosystem where counterfeit goods or exaggerated corporate claims are common concerns.

2.4 Knowledge Gap

While literature on the Pakistani apparel sector addresses variables like brand love, general advertising, and basic brand loyalty, distinct research gaps remain:

• Most existing frameworks focus on direct, short-term influencer marketing conversions, often overlooking the complex, long-term process of building brand and trust amid shifting socioeconomic conditions.
• There is a reliance on quantitative survey methods that capture static consumer attitudes, highlighting a need for systematic literature synthesis and bibliometric mapping to track cross-study reliability.
• Few models evaluate how localized cultural dynamics modify the relationship between digital source credibility and brand trust in South Asian e-commerce landscapes.

2.5 Underpinning Theoretical Extensions

2.5.1 Source Credibility Theory

According to Pornpitakpan (2004), information sources perceived as highly competent, expert, and trustworthy possess a clear advantage in shaping social influence. When target markets rely on peripheral processing, source credibility becomes the primary heuristic used to evaluate a message. When an influencer is viewed as authentic and knowledgeable, consumers form a positive evaluation of the endorsed apparel brand, simplifying the path toward building brand and trust.

2.5.2 Parasocial Interaction Theory

Parasocial interaction outlines the perceived intimacy that media consumers develop with online personalities (Horton & Wohl, 1956; Sokolova & Kefi, 2020). Through daily interactive updates via Instagram Stories or TikTok videos, influencers foster a sense of friendship with their followers. Because of this emotional connection, endorsements are often received as trusted personal recommendations rather than standard paid advertisements.

2.5.3 Theory of Planned Behavior (TPB)

According to Ajzen (1991), conscious human behavior is driven by behavioral intentions, which are determined by attitudes, subjective norms, and perceived behavioral control. This study extends TPB by showing how digital source legitimacy and information quality shape consumer attitudes toward online endorsements, directly influencing final purchase intentions.

2.6 Conceptual Model and Hypotheses

Based on the theoretical synthesis, the following conceptual model is proposed:

• H1: SMIM dimensions positively impact consumer Brand Trust.

• H2: SMIM dimensions positively impact consumer Purchase Intention.

• H3: Brand Trust positively impacts consumer Purchase Intention.

• H4: Brand Trust significantly mediates the relationship between SMIM and Purchase Intention.

Chapter 3: Research Methodology

This chapter outlines the secondary research methodology, database selection criteria, and qualitative synthesis techniques utilized to analyze the current state of digital branding in Pakistan.

3.1 Research Design

This study adopts the structural framework of the “Research Onion” proposed by Saunders et al. (2023) to ensure methodological rigor and compliance with academic ethics.

[Research Onion Stratum Selection]
Philosophy: Positism -> Approach: Deductive -> Strategy: Bibliometric/Secondary Review -> Choice: Mono-method Quantitative -> Time Horizon: Cross-sectional

This study utilizes a secondary quantitative approach alongside systematic thematic extraction. Rather than collecting primary survey data, the study aggregates data from peer-reviewed research papers, books, sector reports, and conference proceedings to evaluate established research trends.

3.2 Research Philosophy and Approach

This study adopts a positivist research philosophy. Positivism is well-suited for systematic literature analysis because it relies on objective data from published academic literature, focusing on verifiable indicators like citation trends, structural model outcomes, and keyword frequencies. By minimizing subjective bias, this philosophy ensures that conclusions regarding building brand and trust are grounded in empirical evidence. The study follows a deductive research approach, moving from established theoretical frameworks (such as TPB and ELM) to analyze trends within the secondary data.

3.3 Data Sources and Search Strategy

Comprehensive bibliographic data was gathered from recognized academic indexes, including Google Scholar, ScienceDirect, Emerald Insight, SpringerLink, and Taylor & Francis, alongside verified industry market reports. The search strategy focused on peer-reviewed articles published over the last decade, using specific search strings:

• ("Social Media Influencer Marketing" OR "SMIM")

• AND ("Brand Trust" OR "building brand and trust")

• AND ("Purchase Intention")

• AND ("Pakistan" OR "Apparel Sector")

3.4 Data Analysis Technique

The collected secondary data was analyzed using comparative and thematic synthesis:

• Study Comparison: Evaluating selected papers based on sample demographics, analysis software, and structural models.
• Statistical Findings Analysis: Synthesizing path coefficients ($\beta$), Cronbach’s alpha levels, and mediation significance values ($p$-values) to evaluate model relationships.
• Thematic Categorization: Grouping findings into core academic themes, specifically focusing on influencer credibility, digital trust development, and purchase intention.
• Pattern Identification: Mapping uniform patterns across studies to see if influencer campaigns consistently assist Pakistani apparel firms in building brand and trust.

3.5 Reliability, Validity, and Ethical Considerations

To ensure scientific validity, only peer-reviewed studies meeting strict measurement criteria were included. The selected literature was reviewed for internal reliability indicators, ensuring the constructs demonstrated high internal consistency (typically marked by a Cronbach’s $\alpha \ge 0.70$ and an Average Variance Extracted $\text{AVE} \ge 0.50$).

Regarding ethical considerations, the study relies entirely on publicly available, published academic work. No primary data was collected from human subjects. Full citation indexing is maintained throughout the text to properly credit the original researchers and preserve academic integrity.
