How many hashtags should I use on a LinkedIn post?

The consensus among LinkedIn content creators and social media analysts is 3-5 hashtags per post. LinkedIn itself has previously suggested this range. Using more than 5 can dilute your targeting and make your post look spammy. Using fewer than 3 means you are leaving discovery opportunities on the table. The key is relevance, not volume.

Do LinkedIn hashtags actually increase reach?

Yes, but with caveats. Hashtags help your post appear in the feeds of people who follow those hashtags, even if they do not follow you. This is especially valuable for growing accounts. However, the impact is modest compared to engagement signals like comments and shares. Hashtags are a discovery tool, not a growth hack. A post with great hashtags but no engagement will still underperform.

Where should I put hashtags in my LinkedIn post?

At the end of your post, on a separate line. Inline hashtags (hashtags woven into sentences) break readability and feel forced. Placing them at the bottom keeps your content clean for human readers while still giving the algorithm the signals it needs for discovery.

Should I use the same hashtags on every post?

No. Your hashtags should match the specific content of each post. If you write about hiring one day and pricing strategy the next, the hashtags should be different. Having a few "anchor" hashtags you use frequently (related to your core expertise) is fine, but at least 1-2 should be specific to the individual post.

How do I find popular LinkedIn hashtags in my niche?

Search for a hashtag on LinkedIn and it will show you the follower count. Check what hashtags top creators in your industry use regularly. Look at posts that perform well in your feed and note their hashtags. This tool generates hashtags in three tiers (high reach, medium reach, low competition) to give you a balanced starting point.

Can hashtags hurt my LinkedIn post performance?

Using too many hashtags (10+) or irrelevant hashtags can hurt performance. If your post appears in a hashtag feed but gets no engagement from that audience, it signals to the algorithm that the content is not relevant. Stick to hashtags that genuinely match your content and audience.

Do hashtags work on LinkedIn articles and newsletters?

Hashtags have minimal impact on LinkedIn articles and newsletters compared to regular posts. Articles are primarily discovered through search (title and body text) and your network. Newsletters reach subscribers directly. You can add hashtags to articles, but the discovery benefit is much smaller than it is for feed posts.

What Does the LinkedIn Hashtag Generator Do?

The LinkedIn Hashtag Generator is a free tool by PublishFlow that generates 15 relevant hashtags for your LinkedIn post, organized into three tiers: high reach, medium reach, and low competition. Instead of guessing which hashtags to use, you describe your topic and get a curated set designed to maximize discovery.

The three-tier approach matters because most people either use only broad hashtags (where their post gets buried) or only niche hashtags (where nobody is looking). Combining both gives your post a shot at wide visibility while also surfacing in smaller, more targeted feeds where you are more likely to be seen.

The tool is free, requires no signup, and generates results in seconds. Describe your post topic, optionally add your industry and audience, and get hashtags you can copy directly into your LinkedIn post.

How to Use This LinkedIn Hashtag Generator

Describe your post topic or paste your content

Enter the subject of your LinkedIn post or paste the actual post content. The more specific you are, the more targeted your hashtags will be. "Demand generation for early-stage B2B SaaS" produces better results than just "marketing."

Add your industry and audience (optional)

Specify your industry and who you are trying to reach. This helps the generator pick hashtags that your target audience actually follows, not just popular ones that attract the wrong crowd.

Generate and review 15 hashtags across 3 tiers

Click generate to get hashtags organized by reach: high reach for visibility, medium reach for targeting, and low competition for standing out. This mix gives your post the best chance of being discovered.

Copy the ones that fit and add them to your post

Pick 3-5 hashtags that match your content and audience. Copy them individually or all at once, then add them to the end of your LinkedIn post. Do not stuff every hashtag into every post.

Why LinkedIn Hashtags Still Matter for Discovery

LinkedIn hashtags serve as a discovery mechanism. When someone follows #productledgrowth and you use that hashtag on a post, your content can appear in their feed even if they do not follow you. For creators trying to grow beyond their existing network, this is one of the few organic tools LinkedIn provides.

The catch is that hashtags alone will not save a weak post. They get your content in front of new eyes, but engagement determines whether those eyes stay. Think of hashtags as the door, not the room. If your post is strong, hashtags help the right people find it. If your post is weak, no combination of hashtags will fix that.

The other nuance is diminishing returns. Using 3-5 well-matched hashtags is optimal. Beyond that, you are diluting your targeting and signaling to the algorithm that you are trying to game the system. LinkedIn has been vocal about rewarding quality content and penalizing engagement hacks, and hashtag stuffing falls into the latter category.

LinkedIn Hashtag Best Practices

Six rules for using hashtags that actually help your posts get discovered.

Use 3-5 hashtags per post, not 30

LinkedIn is not Instagram. Research and testing from content creators consistently shows that 3-5 well-chosen hashtags outperform long hashtag lists. Too many hashtags look spammy and can actually reduce your reach because the algorithm has to decide which hashtag feeds to show your post in. Pick the most relevant ones and skip the rest.

#productledgrowth #saasmarketing #demandgen

#marketing #sales #business #leadership #innovation #growth #success #entrepreneur #startup #motivation #strategy #digital #content #branding #linkedin

Mix broad and niche hashtags together

Broad hashtags like #marketing have millions of followers, which means your post competes with thousands of others. Niche hashtags like #b2bsaascontent have smaller audiences, but your post is more likely to surface. Using both gives you a shot at wide reach and a better chance at actually being seen in the smaller feeds.

#marketing (broad) + #contentledgrowth (niche) + #b2bsaasmarketing (specific)

Using only #marketing #leadership #business for every single post

Match hashtags to the actual post content

Your hashtags should reflect what the specific post is about, not your general expertise. If you wrote about a pricing strategy mistake you made, use hashtags related to pricing and SaaS growth, not generic ones about entrepreneurship. LinkedIn shows your post in hashtag feeds, and people who follow those hashtags will scroll past irrelevant content.

Post about hiring mistakes → #hiringlessons #startupteams #techrecruiting

Post about hiring mistakes → #leadership #success #growthmindset

Follow the hashtags you use regularly

LinkedIn lets you follow hashtags, which means posts using those hashtags appear in your feed. If you consistently use certain hashtags, follow them yourself. This lets you see what other people are posting under those tags, engage with their content, and build visibility within that community. It also helps you spot if a hashtag is too noisy or too dead.

Follow #productmarketing before using it, so you know the community is active

Using hashtags blindly without checking if anyone actually follows or posts in them

Put hashtags at the end of your post, not inline

Hashtags in the middle of sentences break readability. They make your post harder to scan and feel like they were optimized for an algorithm instead of written for a human. Place your hashtags on a separate line at the very end of your post. Some people add a line break before them to keep the main content visually clean.

Write your full post naturally, then add a line break and your hashtags at the bottom.

I just wrote about #contentmarketing and how #b2bsaas companies can use #demandgen to drive #pipelinegrowth.

Do not create custom hashtags nobody follows

Making up a branded hashtag like #AcmeGrowthInsights sounds fun, but if nobody follows it, it does nothing for discovery. Custom hashtags only work for established brands running campaigns. For individual posts, stick to hashtags that already have a following. You can check by searching the hashtag on LinkedIn and seeing the follower count.

#productledgrowth (established community, thousands of followers)

#JohnsMarketingThoughts (zero followers, zero discovery value)
