Frequently Asked Questions.
Common questions about tags, titles, descriptions, and what actually moves a video up in search.
How does the YouTube SEO tool optimise my video title?
The tool analyses your pasted video transcript, identifies the core topic, and rewrites the title using high-search-volume keywords, emotional triggers, and proven click-through patterns. Titles are kept under 60 characters to avoid truncation in search results. The YouTube title checker also flags titles that are too long, too generic, or missing the primary keyword in the first 30 characters where click-through impact is highest.
What are the best YouTube tags for discoverability?
Effective YouTube tags include your exact target keyword, broad category terms, related subtopics, and a few long-tail phrases. The tool builds a balanced mix of high-volume and low-competition tags, up to 30 in a single run, optimised for both broad YouTube search and the suggested video algorithm. That saves the 20-30 minutes most creators spend manually researching tags before each upload.
How many tags should a YouTube video have?
YouTube allows up to 500 characters of tags. Best practice is 10-15 focused tags rather than 30+ generic ones. The tool keeps its set inside that limit and favours specificity over quantity. High-relevance niche tags consistently outperform broad generic tags for both search discovery and suggested placement, so the output leans toward the niche phrases people actually type.
What is a good YouTube video description length?
YouTube shows the first 157 characters of your YouTube description before the "Show more" cut-off, your primary keyword and hook must appear there. A full YouTube video description of 300-500 words, with your keywords appearing naturally 3-5 times, tends to perform best for search ranking. The tool writes a full description from your transcript, including the above-the-fold hook, keyword integration, and a call to action, in one click.
Why do YouTube chapter timestamps help SEO?
Chapters create rich results in Google Search and allow YouTube to surface your video for specific moments, which matters most on longer videos. They also improve watch time by helping viewers navigate to relevant sections, which is one of YouTube's strongest ranking signals. Treat chapters as a structured-data signal rather than a cosmetic one that helps both Google and YouTube index your video's specific topics.
Are there free YouTube SEO tools that actually work?
Yes. CheckTheWorth generates AI-optimised titles, descriptions, 30 tags, chapter timestamps, and metadata in 10 languages from any pasted transcript, no sign-up required. It acts as both a metadata checker and an optimisation tool in a single workflow. Paid tools like TubeBuddy and VidIQ add rank tracking and A/B testing, but for title, description, and tag optimisation, free tools like this are genuinely competitive with paid alternatives for most creators.
How do I find the right channel keywords for YouTube?
The keywords worth setting are phrases that show up in real search queries, not generic category labels. Paste the transcript above and the tool identifies the high-volume, lower-competition keywords your video naturally covers. The keywords you set in YouTube Studio (Settings > Channel > Basic Info) should mirror the top 3-5 keyword themes from your most successful videos, this tool extracts those themes automatically.
