LinkedIn is the world's biggest B2B platform and continues to grow. With increasing numbers of professionals joining the platform, it is harder than ever to stand out. LinkedIn needs to be part of any sales training and strategy, yet most people have not been trained properly or regularly in sales, which is why so many struggle to sell effectively.
LinkedIn is no different from any other professional discipline in this regard. Without proper investment in developing LinkedIn skills, most people are not generating the results they are capable of. The following five mistakes are among the most common — and the most avoidable.
1. Selling as Soon as You Connect
This is the biggest mistake people make on LinkedIn. Sending unsolicited sales messages immediately after connecting damages credibility and risks being blocked. Sales is about relationships first and selling second. Giving as much value as possible, liking and commenting on a prospect's content before connecting, and showing genuine interest will always be more effective than a cold pitch.
2. Sending a Generic Invite
Sending a generic connection request requires no thought or effort and signals exactly that. A personalised invite shows that time has been taken to look at the recipient's profile and read their content. Responding to every invitation, even a generic one, is good practice. Invitations that offer to "explore working together or synergy" are widely recognised as hollow phrases — the focus should always be on how one can help the other person, not on vague collaboration language.
3. Asking a Prospect What They Do
Research is essential before approaching any prospect. Checking what is on their LinkedIn profile, visiting their website, and reading their news, blogs, and case studies demonstrates professionalism and genuine interest. Informing a prospect about an article on their site or commenting on a post puts a person in the top tier of those who engage — the vast majority of LinkedIn users do not take these steps.
4. Having a Blank Header
The LinkedIn headline banner — the rectangular image behind the profile picture — is a missed opportunity when left blank. It should tell people clearly how you help them. A logo alone is rarely sufficient unless the brand is instantly recognisable at scale. The header should also include a clear way for people to make contact.
5. Not Posting Content
Concern about what others will think holds many professionals back from posting on LinkedIn. The reality is that people are not judging others as harshly as they judge themselves. Talking about challenges, sharing how they have been overcome, and entering the conversation in a client's mind — keeping it approximately 80% business and 20% personal — is what builds trust over time. People buy from people, and consistently sharing valuable content is one of the most effective ways to demonstrate expertise.
Bonus: Post Regularly
Posting once in a while never builds momentum. Starting with twice a week, then building to three times a week, and working towards five times a week is a sustainable approach. It can take six to eight months of consistent posting before incoming enquiries begin to arrive. Building a presence on LinkedIn is a long-term investment, not a short-term campaign.
