Best practices

Get the most out of this Automation while staying safe and compliant with LinkedIn's guidelines.

• Stay within LinkedIn limits: LinkedIn monitors all automated activity. To avoid restrictions, keep endorsement volume modest and spread activity throughout the day. Check the latest LinkedIn limits for 2025 to stay compliant.

• Use real, relevant profiles: Only endorse people you actually know or have researched. Random endorsements can look spammy and hurt your credibility.

• Combine with other engagement tactics: Endorsements work best as part of a broader warm-up strategy. Pair them with profile visits, post likes, or comments for stronger engagement signals.

• Space out endorsements: Don't endorse hundreds of profiles in one burst. Spread activity across days to mimic natural human behavior and reduce detection risk.

• Monitor your account health: If you receive an automation warning from LinkedIn, pause activity immediately. Read our guide on what to do if you get flagged.

• Use LinkedIn Flows for sequences: Build multi-step engagement sequences by chaining this Phantom with connection requests, messages, or profile visits for coordinated outreach.

Important: LinkedIn's detection systems have improved. Always operate within safe limits and combine automation with genuine, personalized interactions. If your account gets restricted, follow our step-by-step recovery guide.

Frequently asked questions

Here are the most common questions about using LinkedIn Auto Endorser, from setup and compliance to workflow integration and safety.

What does LinkedIn Auto Endorser actually do?

It automatically endorses a list of LinkedIn users for their top skills. You provide the LinkedIn profiles, and the Phantom visits each one to endorse their displayed skills. This helps you stay visible, warm up prospects, and strengthen relationships without manual clicking.

Is it safe to automate endorsements on LinkedIn?

Yes, when used responsibly. LinkedIn monitors all automated activity, so you must stay within daily limits and mimic natural behavior. Spread endorsements throughout the day, avoid sudden spikes, and always combine automation with genuine engagement. Read our guide on how to automate safely to avoid account restrictions.

How do I get started with LinkedIn Auto Endorser?

Start by following the step-by-step tutorial. You'll connect your LinkedIn account, upload a list of profile URLs, and configure endorsement settings. The Automation runs in the background, so you can focus on other tasks while it works.

Can I use this Phantom with other PhantomBuster Automations?

Absolutely. You can start using this Phantom by itself, or as a building block for some of your LinkedIn Flows. Combine it with profile visits, connection requests, or personalized messages to create full engagement sequences. Check out the warm-up playbook for a complete pre-outreach strategy.

What are the safe limits for endorsing profiles?

LinkedIn doesn't publish exact limits, but safe practice suggests keeping endorsements to 80 per day, and 150 if you have a Sales Navigator account. Avoid endorsing hundreds of profiles in one session. Always monitor your account for warnings and adjust activity if needed. See the latest LinkedIn limits for 2025 for detailed guidance.

Does endorsing people actually help with social selling?

Yes. Endorsements put your name in prospects' notifications, which increases visibility and recognition before you reach out. When combined with profile visits and content engagement, endorsements contribute to a higher LinkedIn SSI score and stronger relationships. It's a subtle but effective touchpoint in modern social selling strategies.

Can I endorse people and then send them a message?

Yes, this is a common warm-up tactic. Endorse a prospect's skills a few days before sending a connection request or message. This primes them to recognize your name when you reach out. After endorsing, use the LinkedIn Message Sender to follow up with personalized outreach. Learn more in our guide on how to automate LinkedIn messages safely.

What data do I need to provide, and what do I get back?

You provide your LinkedIn cookie (session) and a list of LinkedIn profiles to endorse. PhantomBuster returns structured data including the Linkedin Profile details and Email addresses (when available), plus + 21 More fields. See all 3 inputs and outputs to understand exactly what data you'll collect.

How is this different from manually endorsing people?

Manual endorsements take hours and don't scale. The Automation runs in the background, endorsing profiles while you focus on closing deals. It also logs every action and exports data for CRM sync, so you can track engagement and follow up strategically. You get efficiency, consistency, and actionable data in one workflow.

What happens if my LinkedIn account gets flagged?

If LinkedIn detects unusual activity, you may receive a warning or temporary restriction. Stop all automation immediately, wait 24–48 hours, and reduce your activity volume when you restart. Follow our guide on how to fix a restricted LinkedIn account for detailed recovery steps. Always operate within safe limits to minimize risk.
