The score is out of 100 and broken into 5 categories: Title Optimization (25 pts), Description Quality (25 pts), Tags & Keywords (25 pts), Thumbnail (10 pts), and Engagement Signals (15 pts). Each category checks multiple signals and awards partial points based on how well your content is optimized.
A score of 76–90 is considered "Great" — your video is well optimized and should rank competitively. 91–100 is "Excellent." Aim to get above 75 before publishing. Scores below 60 indicate significant room for improvement.
YouTube's search algorithm looks for keyword consistency across your title, description, and tags. A video where the same phrase appears in all three signals sends a strong relevance signal. If your keyword is missing from any of these, you lose ranking potential.
The optimal YouTube title length is 50–70 characters. Titles shorter than 30 characters don't provide enough keyword context; titles longer than 80 characters get truncated in search results and may dilute relevance. Front-load your keyword in the first 3-5 words.
For SEO, aim for at least 500 characters. Descriptions under 200 characters are unlikely to rank well. Include your focus keyword within the first 150 characters (above the fold), add timestamps for long videos, relevant hashtags (3–5), and a call to action.
The optimal range is 8–15 tags. Use a mix of: your exact focus keyword as the first tag, 2–3 closely related phrases, 3–5 broader category tags, and 2–3 long-tail (3+ word) specific tags. Avoid using irrelevant tags or exceeding 20 tags, which can dilute your signals.
Thumbnails don't directly affect search ranking, but they heavily impact Click-Through Rate (CTR). A high CTR tells YouTube's algorithm that viewers want to watch your video, which boosts ranking. Custom thumbnails consistently outperform auto-generated ones.
Engagement signals in your metadata include: using power words in your title (e.g. "How to", "Best", "Ultimate"), numbers in the title, a call to action in your description ("Subscribe", "Like this video"), hashtags in the description, and timestamps that improve watch time.

Check your score before publishing the video, while you still have time to revise. The first 24–48 hours after publishing are the most important for ranking — YouTube uses early performance signals to determine long-term visibility. Optimizing after publishing has limited impact.
