Boolean Search: Your Free Power Tool
LinkedIn's Boolean search works the same on free accounts as it does on Sales Navigator. Master these 5 operators and you'll access 80% of the filtering power without paying a cent.
| Operator | Example | What It Does | Pro Tip |
|---|---|---|---|
| AND | "marketing manager" AND "SaaS" | Both terms must be present | Narrow down results with multiple criteria |
| OR | "CEO" OR "Founder" OR "Owner" | Any of the terms can match | Expand search to include variations |
| NOT | "Sales" NOT "Junior" | Exclude specific terms | Filter out unwanted results |
| "Quotes" | "Head of Growth" | Exact phrase matching | Essential for multi-word titles |
| (Parentheses) | ("VP" OR "Director") AND "Marketing" | Group operators logically | Combine multiple conditions |
Advanced Boolean Template
("VP" OR "Director" OR "Head of") AND ("Marketing" OR "Growth") AND ("SaaS" OR "Software") NOT ("Recruiting" OR "Staffing")This query finds marketing leaders at software companies, excluding recruiters. Typical result: 800-1,200 highly relevant profiles.

When Sales Navigator Makes Sense
Free prospecting has limits. Here's when upgrading pays for itself.
Stay Free If...
- • Prospecting <100 people/month
- • Single ICP, simple targeting
- • Time-rich, budget-constrained
- • Testing a new market/offer
- • Manual outreach is working
Upgrade When...
- • Need 200+ prospects/month
- • Multiple ICPs or complex targeting
- • Time = money, need efficiency
- • Want saved searches + alerts
- • Team needs to collaborate
The Math
Sales Navigator costs ~$99/month. If it saves you 5 hours/month at $50/hour value = $250 saved. If you close 1 extra deal/month from better targeting = easily 10x ROI. The question isn't cost—it's whether you'll use the features.
