Good content alone does not get views on YouTube. The way you write your title, description, and tags directly affects whether your video shows up in search results. This youtube seo checker tool checks all three sections and tells you exactly what to fix.
Analyze Your YouTube Video SEO

What This Tool Does
The YouTube SEO Checker analyzes your video metadata against YouTube’s documented best practices and gives you a score out of 100. It breaks that score into three sections – Title, Description, and Tags, and flags each rule as passed, needs improvement, or failed. So before you publish, you can check your YouTube title, description, and tags all in one place and know exactly what to improve.
You get specific, actionable feedback. Not vague advice. So you know what to change and why.

Frequently Asked Questions
What is YouTube SEO and why does it matter?
YouTube SEO is the process of optimizing your video title, description, tags, and other metadata so YouTube’s search algorithm can understand what your video is about and show it to the right viewers. According to Search Engine Optimization principles, relevance signals in metadata are among the strongest ranking factors on any content platform, including YouTube.
How many characters should a YouTube title be?
YouTube allows up to 100 characters, but titles get truncated in search results around 60 to 70 characters. Keeping your title in that range ensures the full title is visible before someone clicks, which tends to improve click-through rates.
Where should I put my keyword in the YouTube description?
Put it in the first 100 to 150 characters of the description. YouTube and Google both index that section more heavily than the rest. After that, use the keyword naturally two or three more times throughout the full description without forcing it.
How many tags should a YouTube video have?
Most SEO practitioners recommend 10 to 15 tags. More than that can dilute the relevance signal. YouTube also has a hard limit of 500 characters across all tags combined. A good approach is to mix a few broad single-word tags with several long-tail phrase tags (two to four words each).
Does this tool connect to YouTube or access my channel?
No. This tool runs entirely in your browser using JavaScript. It does not connect to YouTube, access your account, or store any of the text you enter. Everything stays on your side.
Can I use this tool before uploading a video?
Yes. That is actually the best time to use it. Paste your draft title, description, and tags in, check the score, make improvements, and then publish. It is much harder to recover ranking after a video has been live for weeks with poor metadata.
Why is my description score low even though I wrote a lot?
A long description alone is not enough. The tool also checks for keyword placement in the first 100 characters, timestamps, links, and a call to action. If any of those are missing, the score will be lower even if your word count is good.
Is this tool free?
Yes. It is completely free with no account required. You can use it as many times as you want.
