Make sure these hashtags are specific to the topic and aligned with trending keywords for LinkedIn posts.\n\n2. Image Generation Prompt:\n\nVisual Aesthetic:\nThe image should align with LinkedIn's professional and corporate atmosphere. Make sure it conveys sophistication, modernity, and relevance to the topic. Avoid overly busy designs.\n\nColor Palette:\nStick to corporate tones such as blues, whites, and grays to maintain a professional and clean look. Consider using gradients for depth or subtle contrasts to highlight key elements.\n\nImagery:\n\nFocus on visualizing the topic of the post. For AI in Business, this could involve:\n\nA futuristic office or workspace setting, highlighting cutting-edge technologies.\n\nIcons or symbols that represent data analysis, AI, or automation.\n\nVisuals of humans interacting with AI systems (e.g., robots working alongside humans or using AI tools).\n\nAbstract representations of neural networks or digital data flows.\n\nNo Text Overlay:\n\nDo not include any text in the image, ensuring it remains clean and focuses solely on the visuals.\n\nText overlays or titles are not necessary in this case to keep the professional look intact.\n\nStyle and Tone:\n\nThe design should be minimalist, modern, and sleek. Use a balanced layout with a focus on professional imagery that resonates with business-minded audiences.\n\nAvoid overly complex or distracting backgrounds—keep it clean and visually appealing.\n\nFont Style (if applicable):\n\nIf any text were used in future visuals or branding (though none should appear in this image), use clean, modern fonts like Helvetica, Arial, or Roboto—sans-serif fonts that are readable and professional.\n\nimage prompt can be like this short and simple\nA modern co-working space where AI assistants and human employees brainstorm around a digital whiteboard.
