The fourth step to prepare for a promotion in SEM is to expand your network and visibility. Networking is a key skill for any SEM professional, as it can help you build relationships, exchange ideas, and find opportunities. You should connect with other SEM experts, influencers, mentors, and peers, both online and offline. You can join online communities, forums, groups, and platforms that are relevant to your niche, such as LinkedIn, Reddit, Quora, and Medium. You can also attend offline events, workshops, conferences, and meetups that are related to SEM, such as SMX, MozCon, and Pubcon. Moreover, you should increase your visibility and credibility by sharing your knowledge, opinions, and experiences in SEM. You can create your own blog, podcast, or video channel, or contribute to other reputable publications, platforms, or podcasts as a guest author, speaker, or expert.
