Online networking can help you build professional relationships, but a generic pitch or a confusing event invitation can make it harder for someone to respond. Avoid these four common mistakes: personalize your first message, make event access straightforward, offer value before asking for it, and look beyond the same familiar contacts.

The phrase “will cost you leads” is a warning, not a measured causal finding: the sources behind this guidance do not establish how many leads any one mistake costs. They do, however, offer practical ways to make outreach more relevant and easier to act on.

What effective online networking looks like

CFA Institute defines it this way: “Online networking refers to connecting, engaging, and building relationships virtually—without the need for in-person meetings.” Its examples include professional social-media engagement, webinars and virtual events, online courses, virtual coffee chats, and professional groups. The common thread is building a relationship, not simply sending a sales message.

Choose one or two platforms where the people you want to reach are active, then participate consistently and professionally. Useful contributions might include a thoughtful response to someone’s post, a relevant resource, or a question that moves a group discussion forward. CFA Institute recommends personalizing outreach, following up after calls or events, and being authentic; it cautions against waiting passively for others to initiate, dominating group conversations, oversharing, or posting needlessly negative or controversial material.

Four digital networking mistakes to avoid

1. Sending canned cold outreach

A generic opening gives a recipient little context for deciding why your message is relevant or legitimate. Benchmark Email’s guidance is to give the person a specific reason to hear from you: refer to a piece of their content, a shared event, or a prior conversation. Keep the connection genuine, and explain why you are contacting this person rather than sending the same pitch to everyone.

Before sending, check that your message answers three questions: why this person, why now, and what small next step are you asking them to take? A brief, relevant note is easier to assess than a broad claim about what your company can do.

2. Making digital-event logistics unclear

An invitation is also an access path. If a recipient cannot quickly understand the event’s purpose, who it is for, when it happens, or how to join, interest can be lost before the event begins. Benchmark Email recommends explaining the event’s value and providing a registration or landing page, with a simple route from invitation to login.

  • State the event’s purpose and the practical benefit of attending.
  • Include the date, time, time zone, and intended audience.
  • Make registration and joining instructions easy to find, and explain what happens after registration.

3. Treating every contact as a conversion opportunity

If every interaction turns quickly into a pitch, people may have little reason to invest in the relationship. Benchmark Email recommends offering something relevant in return for someone’s attention or help—such as useful insight, time, or content. CFA Institute likewise cautions against leading with a sales pitch and encourages useful contributions.

That does not mean giving away something unrelated or pretending to have no business objective. It means making the exchange appropriate: contribute first, ask clearly, and let a commercial conversation develop when there is a reason for it.

4. Keeping your contact list too narrow

Relying only on familiar names can keep you from reaching people who bring different experience, roles, locations, or perspectives. Benchmark Email recommends broadening your reach rather than filtering prospects through assumptions about who might be useful.

Broaden thoughtfully, not indiscriminately. Look for a credible connection to the person’s work, a shared professional interest, or a relevant conversation. A wider set of well-chosen contacts is not the same as mass messaging strangers.

How to choose a platform and make follow-up useful

There is no universally best platform in the sources reviewed. Choose based on whether your intended professional audience is active there, whether you can contribute something useful, and whether you can maintain a professional tone. A platform is a poor fit if it reaches many people but does not support a relevant conversation.

Consistency can help keep you visible, but it is not proof of lead generation. In a January 2025 analysis of more than 100,000 Buffer users who had posted in the preceding 26 weeks, Buffer reported that users posting in at least 20 of those weeks had more than five times the median engagement per post of users who posted in four weeks or fewer. The comparison concerns likes, comments, shares, and other platform interactions; it is observational company-user data, not evidence that posting frequency causes leads.

After a virtual event or call, send a short follow-up that thanks the person, refers to a point from the conversation, delivers anything you promised, and suggests one relevant next step. CFA Institute recommends following up, but its guidance does not establish a universal deadline such as 24 hours. Follow through when you said you would, and make the next step easy to accept or decline.

A quick check before you send

  • Personalization: Does the message refer to something specific and relevant to this person?
  • Value: Is there a useful reason for them to engage beyond hearing your pitch?
  • Next step: Is your request clear and proportionate?
  • Access: For an event, are the purpose, time, registration, and joining steps straightforward?
  • Follow-through: Can you deliver what you promise and follow up appropriately?
  • Audience: Are you reaching beyond familiar contacts while still choosing people for a relevant reason?

Which networking claims deserve caution?

Benchmark Email’s 2020 article repeats a claim that 75 percent of surveyed executives would schedule a meeting or attend an event after only a cold call or email. Its cited page is a 2018 secondary Medium post that credits DiscoverOrg but does not provide the underlying survey method or original study. That figure should not be treated as a verified estimate of how executives respond.

For the four practices themselves, see Benchmark Email’s original four-mistake framework and CFA Institute’s April 7, 2025 guide, “Networking online: the dos and don’ts”. Buffer’s analysis and the secondary page behind the 75-percent claim are available at Buffer and Medium, respectively.
