LinkedIn Semantic Post Search
marketing
Usage is simple: -You input text describing the topic you want to learn about. -You get a list of posts on that topic. We also gather meta-data on each post, like the author, level of engagement on the post, and the commenters. This bot can be used to build a list of contacts posting on a topic, which can be a valuable intent signal. We’ve used this bot to connect with influencers posting on topics related to Surudo’s business. For example, here's a great way to build an account list if you’re selling a CRM to wealth management firms: search for wealth management companies that have posted about issues with current CRMs.
