How to Find the Best Marketing Agency for Your Business on LinkedIn

Finding the right marketing agency is a high-stakes decision, and LinkedIn has quietly become one of the most powerful tools in your corner. A joint study by LinkedIn and Edelman found that 55% of decision-makers use thought leadership content to vet the organizations they might hire. LinkedIn gives you a front-row seat to how agencies think, communicate, and show up as industry leaders.

With 4 out of 5 LinkedIn members involved in business decision-making, this platform isn’t just where agencies post but where they prove themselves. From insightful posts and meaningful comment threads to real-time engagement with clients and prospects, the best agencies use LinkedIn to showcase what they do and how well they do it.

In this guide, we’ll show you how to use LinkedIn to evaluate and connect with top-tier agencies so you can find a partner who doesn’t just talk marketing but delivers results that matter.

Define Your Needs First

Before finding a marketing agency on LinkedIn, you should first define the kind of marketing help you need. When you know what you intend to accomplish, you can set clear expectations and assign resources accordingly.

For instance, your goal could be:

• Brand awareness: Familiarizing your target audience with your product or service.
• Lead generation: Identifying potential consumers to engage with and increasing conversions through paid advertisements and organic SEO. 
• Content marketing: Creating and distributing content across your website and social channels. 
• SEO improvement: Generating website traffic and improving your visibility on search engines with SEO optimizations.
• Partnership/influencer collaboration: Arranging partnerships and collaborating with influencers to promote your products and services. 

Once you’ve chosen your goal, create a budget and an estimated timeline to find a marketing agency that fits your needs. Decide also if you need a full-service agency with fractional CMO leadership or one that specializes in one area, such as PPC, SEO, content marketing, or influencer marketing.

There’s no right or wrong way to find a marketing agency on LinkedIn. Here are a few ways to find and connect with a potential agency partner.

Conduct a LinkedIn Agency Search

A LinkedIn agency search lets you find marketing agencies that engage and share thought leadership in real time.

Instead of just searching with the term “marketing agency,” use LinkedIn’s filters to narrow your search. For example, if you need an SEO agency, type in “SEO marketing agency” or “SEO specialists.” 

Use the location filter to find agencies in your city or state.

If you prefer a smaller agency, apply the company size filter to see what agencies are available in your area.

Join LinkedIn Groups 

If you’re a fan of reading discussion threads and customer reviews, join groups like Advertising & Marketing Professionals or Digital Marketing: Social Media, Search, AI Marketing, Mobile & more. These groups often have agency recommendations and discuss different topics every day. Participate in these spaces to see which agencies provide helpful information.

Check Your Mutual Connections & Ask for an Introduction 

If you’ve compiled a list of agencies recommended by others in a LinkedIn group or from your research, check your network to see if you have any mutual connections. If someone you’re connected with has a connection with a marketing agency on your list, send them a private message asking for an introduction. 

Here’s an example of a message you can send:

Hi, [connection’s first name], 

I hope you’re having a great week so far! I saw you’re connected with someone from [agency name] and was wondering if you could introduce me. I’m currently looking for a new marketing agency partner, and their team looks like an excellent fit for our marketing needs. If this is something you’re comfortable with, please let me know. 

Thank you in advance for your time and consideration.

Warm regards,

[Your name] 

If you don’t have any mutual connections, ask your network for referrals by sharing a post of what you’re looking for in a marketing agency. Roughly 88% of people are more likely to trust a brand if someone they know recommends it. 

Follow & Engage With Agencies 

If you’re not ready to contact a marketing agency directly, try following their page and any employee who posts regularly on LinkedIn. Following agencies and engaging with them for a few weeks is a great way to see how they interact and share insights to determine if they fit your organization. 

How to Evaluate an Agency’s Credibility on LinkedIn

A well-designed company page isn’t enough to judge an agency’s credibility;   LinkedIn thought leadership content matters, too. Ask yourself, “Does the agency share practical information and industry insights or merely promote itself?” Agencies that provide valuable content show expertise and a proactive marketing approach.

Beyond content, check how the team interacts on LinkedIn. Use the “People” filter on the company page to see if employees beyond the CEO are active and engaged. A visible and engaged team on LinkedIn signals a culture of teamwork and innovative thinking. 

Client interactions also reveal a lot. Whether past or current clients like, comment on, or endorse the agency’s posts is a strong sign of trust and satisfaction.

Here’s a complete checklist of what to look for in a marketing agency on LinkedIn:

• Are they active and consistent with posting?
• Do multiple employees post on LinkedIn or just the CEO? 
• Do they position themselves as an industry thought leader? 
• Based on their page and posts, can you tell what the agency specializes in?
• Are clients liking, commenting, or sharing posts? 
• Do they show results or just talk about getting results? 

What Great LinkedIn Thought Leadership Looks Like (and Why It Matters)

When evaluating agencies on LinkedIn, don’t just scroll past their posts — read them. The way an agency communicates online is a strong reflection of how they think, how they work, and what kind of partner they’ll be. LinkedIn is one of the clearest windows into the brains behind the brand.

But what does great thought leadership actually look like?

• Actionable insights: Thought leadership should go beyond fluff. Look for posts that offer real strategies, frameworks, or tips that help solve challenges, not vague marketing speak.
• Industry trends and analysis: The best agencies don’t just ride the wave. They spot the shifts before they happen. Look for commentary on industry trends and what they mean for businesses like yours.
• Authenticity and personal experience: Thought leadership is most powerful when it’s honest. Behind-the-scenes stories, lessons learned, and “here’s what worked (or didn’t)” content builds trust.
• Fresh and unique perspectives: Great thought leadership doesn’t regurgitate what everyone else is saying. It challenges assumptions and sparks conversation with bold ideas.

If an agency is consistently producing this kind of content, you’re looking at a team that truly thinks. And that’s exactly the kind of partner you want guiding your strategy.

Reaching Out and Starting Conversations

If you come across a potential lead by yourself or through your network, reach out to a company contact and start a conversation. To get a response, personalize your message by referencing an insight you found valuable. Ask specific questions about the agency’s approach to your industry. 

You can ask:

• How do you measure marketing success?
• Can you share specific campaign results?
• How do you market your agency on LinkedIn?
• How do you balance paid vs. organic efforts in your campaigns? 

Here’s an example of a message you can send: 

Hi, [nameofcontact],

I’m [firstname] with [organization]. I recently came across your marketing agency on LinkedIn and was impressed with what you and your team have accomplished. I’m looking for a trusted marketing agency partner to help us with [marketing goal/objective] and was curious to know what we could achieve together. Are you available for a quick chat this week? 

Sincerely,

[Name] 

Before signing on with a marketing agency, watch out for red flags. If its responses feel generic or copy-pasted without directly addressing your needs, it may indicate a one-size-fits-all approach rather than a tailored strategy. Here are a few other signs to watch out for.

No Case Studies or Proof of Results

Avoid a potential partner who only talks about how much they can help you accomplish. They need to prove what they can achieve with case studies and impactful KPIs. When researching marketing agency partner profiles on LinkedIn, check if they’ve posted any case studies. If you can’t find them directly on the agency’s page, they’ve mostly been shared by the company’s CEO or other executive leaders. 

Overpromising & Underdelivering

How often have you heard a marketing sales rep promise you the number-one ranking on Google? Once you sign on as a client and don’t see the results they hyped up, the reality becomes clear — they overpromised and underdelivered. 

No marketing agency can guarantee you the top ranking since Google’s algorithm is constantly changing. Instead, you need a partner who has a game plan with realistic expectations because actual results aren’t bought — they’re earned. 

Poor Communication in the Early Talking Stages

If you’ve reached out to a contact from a marketing agency on LinkedIn, and they’ve been inconsistent or silent in their communication, this is a major red flag. Their lack of interest and effort in the early talking stages reflects how they will view your business relationship.
