Some common mistakes people make when setting up their LinkedIn profiles include using incomplete or outdated information, which can harm their professional image. Failing to use a professional photo or an appropriate headline can also negatively affect first impressions. Many users overlook the importance of keywords, making it harder for recruiters to find them. Neglecting the summary section is another mistake, as it’s a great opportunity to showcase personality and career goals. Using a LinkedIn makeover service can help you avoid these pitfalls and optimize your profile for better visibility and engagement.
