The format of your achievements depends on the type and structure of your resume, but generally, you should use bullet points to list them under each relevant work experience or project section. Start each point with a strong action verb that describes what you did, followed by the details and metrics of your achievement. Additionally, use consistent punctuation, capitalization, and tense throughout your resume. For example, when listing achievements from a role as Marketing Manager for ABC Inc., you could include launching a successful online marketing campaign that increased website traffic by 50% and generated 200 new leads in three months, managing a team of five marketing specialists and coordinating their tasks, budgets, and deadlines for various projects, and creating and delivering engaging presentations and reports to senior management and clients on marketing performance and strategy. Similarly, when detailing accomplishments from a project such as Website Redesign for XYZ Ltd., you could include designing and developing a user-friendly and responsive website for a small business using WordPress and HTML, conducting user testing and research to identify and implement improvements and enhancements based on feedback and data, as well as achieving a 90% satisfaction rating from the client plus a 30% increase in conversions from the website visitors.
