The free YouTube Tag Generator on iWebSeoTool builds a ready-to-paste list of tags from your video title and main keyword, right in your browser — nothing is uploaded and no sign-up is needed. Type your title, add your keyword if you have one, and click Generate Tags to create a list that fits YouTube’s 500-character tag budget. You can also switch to the built-in youtube tag checker to review tags you already use.

How to use the YouTube Tag Generator
1. Enter your video title (up to 100 characters) in the Video title box. 2. Add your main keyword if you have one — this gives the most relevant suggestions — and leave the category on Detect automatically, or pick your video’s category yourself. 3. Click Generate Tags. Your tags appear on the right as removable chips, with a live character meter for the 500-character limit. 4. Click Copy Tags and paste the list into the Tags box in YouTube Studio. Remove any chip that does not fit your video first. Prefer to generate youtube tags for a video that is already published? Paste its current tags into the Tag Checker mode instead and fix duplicates and over-long tags there.
What makes good tags for YouTube videos?
Put your most specific tags first: your exact topic and main keyword matter more than broad one-word tags. Mix exact phrases from your title with a few wider category phrases, cover common misspellings of your main terms where they are genuine, and use the whole character budget only on tags that honestly describe the video. Tags are a small discovery signal — they help YouTube understand your topic and connect searches with different wording — but your title, description, thumbnail and watch time carry far more weight, and no tool can promise rankings.
Checking tags you already have
The Tag Checker mode reviews an existing tag list against the limits YouTube applies. Paste your tags separated by commas and it counts them, totals their characters, highlights duplicates (which waste space, because YouTube ignores repeats) and flags any single tag longer than 100 characters. It is the quickest way to tidy up tags for youtube videos you published before you had a process.
YouTube tag limits to remember
YouTube allows up to 500 characters of tags per video, counting the commas between them, and a single tag can be up to 100 characters. This youtube tags generator keeps your list inside the budget as it builds it, leaving out lower-priority suggestions rather than silently cutting your list in YouTube Studio. Fewer, accurate tags beat a stuffed list: misleading tags break YouTube’s metadata policy and can hurt a channel.

Frequently asked questions
It builds suggestions from your video title and optional main keyword using proven phrase patterns — such as tutorial, tips, guide and for beginners versions of your keyword — plus a few phrases for your video’s category. It does not connect to your YouTube account or copy tags from other videos, so always remove any suggestion that does not fit your video.
Use as many relevant tags as fit naturally inside the 500-character budget — for most videos that works out to roughly 10 to 20 tags. Put the most specific phrases first, and never add popular but unrelated tags: misleading metadata goes against YouTube’s policy and can hurt your channel.
No. The generator and checker run entirely in your browser; your title, keyword and tags are never sent to our server or stored, and you do not need an account.
Yes. The generator and the tag checker are completely free on iWebSeoTool, with no sign-up and no limits on how often you use them. Everything runs in your browser.
Paste in tags you already use and it counts them, totals their characters, highlights duplicates and flags any tag longer than 100 characters. You get a copy-ready list you can clean up with one click per tag.
YouTube allows up to 500 characters of tags per video in total, including the commas between tags, and each single tag can be up to 100 characters. The tool shows a live meter as it builds your list and keeps the suggestions inside that budget.
No tool can guarantee that, and tags are only a small signal. They mainly help YouTube understand your topic and match searches that use different wording or misspellings. Your title, thumbnail, description and watch time matter much more — treat tags as tidy finishing metadata, not a shortcut.
