How to Use LinkedIn Search Filters

The search bar on LinkedIn is far more potent than a simple tool for finding old colleagues. It's a discovery engine that can connect you with ideal clients, top-tier job candidates, and industry leaders if you know how to wield it properly. This guide will walk you through exactly how to use LinkedIn's powerful search filters to go from broad, vague searches to laser-focused results that can transform your professional efforts.

Getting Started: Your Gateway to Advanced Search

Most LinkedIn users type a name or a job title into the search bar, hit enter, and stop there. The real power, however, is hidden behind one more click. Let's start with the basics of a People search.

1. Type a general term into the main search bar at the top of your LinkedIn homepage (e.g., "Marketing Manager").

2. On the results page, you’ll see several tabs like "People," "Jobs," "Posts," etc. Click on People.

3. Now, you'll see a row of basic filters appear just below the search bar: Connections, Locations, and Current company. These are a good start, but the magic happens when you click the “All filters” button to the right. This opens a sidebar loaded with options to refine your search.

This "All filters" panel is your command center for finding exactly who you need to find.

Mastering People Search Filters: A Deep Dive

Finding the right people is the most common use case for LinkedIn search, whether for sales, recruiting, or networking. Let's break down the most impactful filters available in the "All filters" sidebar.

1. Connections

This filter allows you to segment results based on your relationship to them. Understanding these levels is fundamental.

• 1st Degree: People you are directly connected with. You can message them directly for free. This is your immediate network.
• 2nd Degree: People who are connected to your 1st-degree connections (friends of friends). This is often the sweet spot for warm introductions. You can send them a connection request with a personalized note, and you may see shared connections who can introduce you.
• 3rd+ Degree: People who are connected to your 2nd-degree connections. This is the broadest network and represents the biggest pool for new opportunities.

Strategy: Start with 2nd-degree connections when looking for new clients or collaborators. The mutual connection adds a layer of social proof, making your outreach feel less like a cold call.

2. Locations

This one seems simple, but it's hugely important for local business, event planning, or targeted regional campaigns. You can add multiple locations to a single search to cover entire regions. For example, a search for “Denver, Colorado,” “Boulder, Colorado,” and “Colorado Springs, Colorado” will give you professionals across the Front Range.

3. Current Company and Past Company

These filters are gold mines for sales and recruiting.

• Current Company: Target employees at a specific organization. Want to find all the sales directors at Salesforce? This is how you do it.
• Past Company: Find people who used to work somewhere. This is fantastic for identifying “alumni” networks or finding people with specific domain experience (e.g., finding candidates who previously worked at a top competitor).

Example: Combine these to find people who currently work at "Microsoft" but previously worked at "Google." This could help you identify individuals with experience in two complementary tech ecosystems.

4. Industry

Running a marketing agency for SaaS companies? Use the "Industry" filter to select "Computer Software" or "Information Technology and Services." This instantly cuts out irrelevant noise from your results, ensuring you're only seeing people in your target market. It’s one of the quickest ways to qualify prospects.

5. Profile Language, School, and Service Categories

• Profile Language: Essential for international outreach or recruitment.
• School: A great way to tap into your alumni network for job opportunities, mentorship, or warm introductions.
• Service Categories: This filter is especially useful for finding freelancers or consultants. It allows you to find people who have explicitly listed services on their profile, such as "Marketing Consulting" or "Graphic Design."

6. Keywords (The Ultimate Power-Up)

At the bottom of the "All filters" panel, you'll find the ultimate tool: the Keywords section. This lets you search for specific terms within a person's entire profile. It includes fields for Title, Company, School, and a general Keywords field. Here’s how to use it like a pro with Boolean search operators.

Boolean search is a straightforward way to combine or exclude keywords to get more precise results. The main operators are:

• Quotes (“ ”): Use quotes to search for an exact phrase. For example, searching for "Director of Content Marketing" will return people with that exact title, not people with "Director" in one part of their profile and "Content Marketing" in another.
• AND: Use this to find profiles containing all your keywords. The search "Founder" AND "SaaS" will only show you people who have both terms in their profile. (Note: On LinkedIn, a space between two words often functions as AND.)
• OR: Use this to broaden your search and find profiles containing at least one of your keywords. For example, "Marketing OR Advertising" will find people in either field. This is perfect for job titles that have multiple variations, like "Social Media Manager" OR "Community Manager".
• NOT: Use this to exclude profiles containing a specific keyword. If you’re looking for a senior designer but keep seeing student roles, you could search for "Graphic Designer" NOT "Intern".
• Parentheses ( ): Use these to group operators and create more complex searches. This is where you can get really precise.

Putting It All Together: A Pro-Level Search Example

Imagine you're a recruiter looking for an experienced product manager in the fintech space, but you want to avoid candidates from very large C-suite teams. Your search could look like this:

("Product Manager" OR "Head of Product") AND (Fintech OR "Financial Technology") NOT (VP OR CPO)

This command tells LinkedIn to find profiles that contain either "Product Manager" or "Head of Product," and contain either "Fintech" or "Financial Technology," but to exclude any profiles that also list "VP" (Vice President) or "CPO" (Chief Product Officer). By combining operators, you create an incredibly targeted list.

Using Filters for More Than Just People

While people search is king, the "All filters" principle extends to other useful parts of LinkedIn.

Content Search Filters

Curious what people are saying about a topic? Search for a term like "short-form video strategy" and then click the "Posts" tab. You can filter content by:

• Posted by: See content just from your 1st-degree connections or a specific person.
• Date posted: Find the most recent conversations (Past 24 hours, Past week, Past month).
• Sort by: View either the most recent content or the "Top Match," which highlights the most engaging posts first. This is great for identifying industry trends and influential voices.

Company and Job Search Filters

Looking for a new role or creating a list of companies to target? The same logic applies.

• Jobs: Filter by experience level, job type (full-time, contract), location (on-site, remote, hybrid), and even salary (in some listings).
• Companies: Looking for SaaS startups to sell to? Filter the "Companies" tab by Industry ("Computer Software"), Company size ("11-50 employees," "51-200 employees"), and Location to build a hyper-specific list of target accounts.

The Strategic Workflow: From Filters to a Pipeline

Knowing how the filters work is one thing, using them strategically is another. Here’s a simple workflow to turn these tools into a reliable system for prospecting or networking.

1. Define Your Persona: Before you even touch the search bar, get clear on who you're looking for. What is their job title? What industry are they in? What size company do they work for? Where are they located?

2. Translate Your Persona into Filters: Now, map those attributes directly to LinkedIn's filters. "Marketing Director" goes in the title keyword. "B2B SaaS" goes into the general keywords. "50-200 Employees" gets selected under company size.

3. Run and Refine: Run your search and see what you get. Are the results too broad? Add a NOT operator to exclude an irrelevant keyword. Too narrow? Use an OR operator to include an alternative job title.

4. Save Your Search: With LinkedIn premium and Sales Navigator, you can save searches and get alerts when new people match your criteria. On a free account, you can simply bookmark the unique URL of your search results page. Visit it weekly to see new people who fit your perfect profile.

This process transforms reactive searching into a proactive system for consistently finding the right people, content, or companies.

Final Thoughts

Mastering LinkedIn search filters turns the platform from a simple social network into a powerful professional database. By moving beyond basic keyword searches and leveraging the full suite of filters - especially with Boolean logic - you can uncover opportunities, build precise prospect lists, and connect with the exact people who can move your career or business forward.

Once you've spent the time finding the right audience, the next step is keeping them engaged with consistent, valuable content. This is where my team and I saw a huge opportunity to simplify a common headache.
