LinkedIn is, by the very nature of its design, a perfect social platform for fueling B2B lead generation efforts. Just not in the same manner you would traditionally do on platforms such as Google Ads or Instagram.
With LinkedIn, you are better off running paid campaigns for people to download an eBook, register for a webinar, offer a free product sample, or promote an event. It isn't about the hard sell on LinkedIn, it is about building relationships, educating and helping others succeed. Only when they start succeeding, will you on this platform.
