    Tags still influence YouTube discovery, but writing 10-15 strong ones for every upload is exhausting. The Fulhar YouTube SEO & Tag extension fixes that. Open any video on YouTube and a side panel reveals its real tags, view-velocity score, top-ranking keywords, and a one-click viral tag generator for your own uploads.

    Lighter than vidIQ or TubeBuddy (under 1MB), zero tracking, and free to install — most users keep it pinned to their toolbar permanently. Compatible with every Chromium browser.

    Frequently asked questions

    Is the YouTube SEO and tag extension really free?

    Yes. Install and use unlimited tag generation, view counts, and competitor tag analysis on the free tier. Heavy commercial use (1000+ tag generations per day) is on a paid tier.

    How is this different from vidIQ or TubeBuddy?

    vidIQ and TubeBuddy are excellent — but heavy (50+MB), feature-bloated, and gate the basics behind paid tiers. Fulhar's extension is sub-1MB, focused on tags + SEO + competitor analysis, and the free tier is genuinely usable.

    Does YouTube still use tags for ranking?

    Less than they used to, but yes — tags still influence YouTube's understanding of your content (especially for Shorts and lower-view-count videos). They remain a valuable, low-effort SEO lever.

    Will my YouTube account be safe?

    Yes. The extension only reads page content (no YouTube API access, no OAuth). It can't post, modify, or delete anything on your channel. Pure read-only.

    Which browsers work?

    Any Chromium browser: Chrome, Edge, Brave, Arc, Opera, Vivaldi. Firefox version is on the roadmap.

    Is my data tracked?

    No. Zero telemetry, zero analytics scripts. The only network calls are to YouTube and Fulhar's tag generation API.

    Can I use it without a Fulhar account?

    Yes — most features work without login. Sign in only to save tag lists or get personalised tag suggestions based on your channel's niche.

    Ready to add to chrome?

    Free to start. No credit card. Sign in only when you're ready to save your work.
