FAQs

Do hashtags still work?
Yes — hashtags help categorize content and improve discoverability across platforms.
How many hashtags should I use?
It depends on the platform, but quality and relevance matter more than quantity.

Do hashtags still work for increasing reach?
Yes, hashtags remain a vital tool for content discovery and categorization. While they are no longer the only factor in viral growth, they provide essential signals to social media algorithms about who should see your post. By using relevant, AI-generated tags, you help platforms index your content correctly, making it easier for users searching for specific topics or following certain interests to find your profile.
Should I put hashtags in the caption or the first comment?
Both methods are effective for SEO and discoverability, so the choice often comes down to aesthetic preference. Placing hashtags in the caption makes them immediately visible, while the first comment keeps the caption area clean. Postly supports both options, including an automated first-comment feature that ensures your hashtags are published instantly alongside your post, maintaining your reach without cluttering your message.
How many hashtags should I use for the best results?
The ideal number of hashtags varies by platform. For Instagram, while you can use up to 30, many experts recommend 3-5 highly relevant tags to maintain a professional look. On LinkedIn, 3 tags are generally considered optimal. TikTok often rewards a mix of 3-6 broad and niche tags. Postly’s generator helps you find the most relevant options so you can focus on quality rather than just quantity.
