Access 10-Platform-Tuned Generators from 1 Tool
You need 3 different hashtag sets when you post the same client photo to Instagram, Facebook, and LinkedIn. RecurPost’s hashtag generator solves this problem and gives you AI-generated hashtags for each platform.
10 social media platforms that include the hashtag generator tool are:
- X/Twitter
- TikTok
- YouTube
- Threads
- Bluesky
- Google Business Profile
Describe your post or paste an existing caption as the same input for each version. Get hashtag sets styled for each platform. This is a free tool that works on the browser and doesn’t need sign-up.
Agency example: The Instagram generator suggests a broad mix of discovery and niche-based tags, while the LinkedIn generator provides industry-specific tags for a professional feed.
Best for: anyone posting the same content to more than 1 platform. Less useful for a person who posts to a single platform. Go to any of the platform-specific hashtag generators on RecurPost to get quick tags for one-off posts.
Per-Platform Hashtag Norms: Why 1 Hashtag List Doesn't Work for 10 Platforms
RecurPost’s Hashtag Generator aligns with platform-specific rules to suggest hashtag options for each post. Each platform sets a different hashtag limit based on the native characters it supports and serves different goals. On LinkedIn, your hashtags are used as topic markers for a professional audience. Conversely, Pinterest uses hashtags as descriptive search terms. Google Business Profile doesn’t accept hashtags as clickable at all.

Generate Hashtags in 4 Steps and Open Specific Platform Pages to Tune Output
Follow the 4 steps in RecurPost to generate hashtags:
Enter a keyword
Enter any keyword or a short description for the post.
Choose the count
Choose the number of hashtags you need.
Generate the list
Generate the list of hashtags.
Copy and publish
Copy the hashtags into platform-specific posts.
RecurPost hashtag generator follows per-platform norms to create hashtags. Open the matching platform generator pages instead of the count selector for this scenario.
Use the RecurPost generic page for quick first-pass drafts without platform-related captions. A blog excerpt repurposed for a newsletter, infographic, or simple one-off Facebook post doesn’t fulfill the engagement or CTR needs for client posts on specific platforms. For that, surf between the different platform-specific generator pages if you post to your client’s TikTok account and YouTube Shorts.
See the Instagram generator or the LinkedIn generator, or any other 8 network pages.
Note: This page features the overview for 10 separately platform-tuned hashtag generator URLs, rather than a single-page dropdown menu. Bookmark any of the 10 platform generator pages to reuse on its own without searching for the selector every time.
Go to plug-ins beside your account name at the bottom left of the RecurPost dashboard. Click on ‘Manage’ under the ‘Hashtags’ box. Select a library. Add a keyword to replace with a hashtag. Get hashtags suitable for the particular network.
Bags of Tags: Save and Reuse Hashtag Groups for Client's Recurring Posts
Save the AI-generated hashtags into groups called ‘Bags of Tags’ in RecurPost for reuse at any time and on any social platform.
Use a combination for your scheduled posts per platform in RecurPost’s evergreen and seasonal content libraries with saved ‘Bags of Tags’. Steps include:
- Schedule a recurring post from the evergreen library
- Attach matching hashtag bags
- Avoid manual tagging for each reshare/repost
Read how to manage evergreen content for clients on RecurPost’s evergreen content marketing page.
Agency example: when you manage 8 client accounts spanning across different industries (real estate, B2B SaaS, insurance), generate, save, use, and reuse Bags of Tags in each of their recurring posts to separate platforms.
Best for: reposting evergreen content. It is suitable for posts where the same hashtag groups fit. The hashtags naturally do not fit a new topic or trending moment.
Choose the Right Platform-Specific Hashtag Generator in RecurPost for Client Accounts
Open the RecurPost platform hashtag generator on the network where the post will upload.
Agency example: client posts to 3 platforms (TikTok, Instagram Reels, and YouTube Shorts) — you visit 3 platform-specific hashtag generator pages thrice, and each generator page creates 1 hashtag set to match platform norms.
Best for: any agency or freelancer that manages 2+ platforms per client. Also useful for freelancers who post to single platforms; must bookmark the platform-native generator page for reuse.
RecurPost Hashtag Generator FAQs
What social platforms does RecurPost's Hashtag Generator support?
RecurPost’s Hashtag Generator covers 10 social platforms: Instagram, Facebook, X (Twitter), TikTok, YouTube, Pinterest, Threads, LinkedIn, Bluesky, and Google Business Profile. Each platform has its own generator page tuned to that network’s hashtag norms.
Is RecurPost's Hashtag Generator free to use?
RecurPost’s Hashtag Generator is free. It runs in the browser and doesn’t require a sign-up. You can generate hashtags for any of the 10 supported platforms without creating a RecurPost account first.
Why doesn't the same hashtag set work on every platform?
Each platform rewards a different hashtag count and style. Instagram supports up to 30 tags and rewards a broad-plus-niche mix. LinkedIn performs best with three to five topical tags. Google Business Profile doesn’t render hashtags as clickable at all. RecurPost’s platform-specific generators apply the count and style that fits the destination platform instead of one shared list.
What is a Bag of Tags, and how does it help an agency manage several clients?
A Bag of Tags is a named, reusable hashtag set you save inside RecurPost and pull into future posts without regenerating. An agency can save one Bag of Tags per client niche and reuse it on that client’s recurring posts, cutting out repeat manual tagging.
Which hashtag generator should I use for a client's Instagram Reel versus a Google Business Profile post?
Use the RecurPost generator that matches the platform the post is actually going to. Open the Instagram generator for the Reel and the Google Business Profile generator for the GBP post. Each one applies the tag count and style built for that specific platform.
Does RecurPost's Hashtag Generator stay current with hashtag trends?
RecurPost’s Hashtag Generator refreshes its trending hashtag suggestions on a regular cycle, so the tags it returns reflect current activity rather than a static list.
