Search engine optimization allows for users’ needs to be directly met by result snippets or a “knowledge map” without clicking any results. This behavior is called “good abandonment” and is found to frequently occur during mobile searching. Users exhibit such a behavior when they trust the result that addresses their information need without bothering to click it. Therefore, this study examines how users judge a result's credibility without clicking. This study proposes a model for assessing the credibility of good abandonment results, making a hypothesis about the measures that may affect credibility assessments in mobile searches. A credibility assessment experiment was conducted to collect users’ eye movements, perceived credibility and feedback on different credibility measures. Users’ search behaviors were recorded by a screen recorder, in order to see whether a search was good abandonment. Then the initially proposed model was validated in terms of users’ perceived credibility, search behaviors and feedback, and further improved. The revised model found that the credibility assessment of good abandonment results in mobile searching is determined by six credibility measures distributed across three aspects of content, operator and design. Content-related measures show that users tend to believe the results if there is detailed and updated context information and the content is neutral. Operator-related measures indicate the impact of trust in the search engine on the credibility assessment. Design-related measures indicate that users tend to trust results with interactive functions and optimal layouts. How each of the six measures influence users’ assessment of credibility is discussed in this paper.

搜索引擎优化允许结果片段或“知识图”直接满足用户的需求，而无需单击任何结果。这种行为被称为“良好放弃”，并且在移动搜索过程中经常发生。当用户信任可以解决其信息需求的结果而无需打扰它时，他们就会表现出这种行为。因此，本研究考察了用户如何无需点击即可判断结果的可信度。这项研究提出了一个模型，用于评估良好放弃结果的可信度，并对可能影响移动搜索中可信度评估的措施进行了假设。进行了信誉评估实验，以收集用户的眼球运动，感知的信誉以及对不同信誉指标的反馈。用户的搜索行为是由屏幕录像机记录的，以便确定搜索是否被放弃。然后，根据用户的感知信誉，搜索行为和反馈对最初提出的模型进行了验证，并对其进行了进一步的改进。修改后的模型发现，移动搜索中良好放弃结果的可信度评估由分布在内容，运营商和设计三个方面的六个可信度指标确定。与内容相关的度量表明，如果有详细和更新的上下文信息并且内容是中性的，则用户倾向于相信结果。与运营商相关的措施表明了对搜索引擎的信任对信誉评估的影响。与设计相关的度量表明用户倾向于通过交互功能和最佳布局来信任结果。
