How to Use ThrillKit's SEO Optimizer

Getting Started

Head to /seo-optimizer. You can analyze a video in two ways:

• Paste a YouTube URL — The optimizer pulls your existing title, tags, and description, then scores and suggests improvements for each field
• Type a title or topic — If you haven't uploaded yet, describe what your video is about and get optimized metadata before you even hit publish

Free users receive a full SEO score plus baseline suggestions for each field. Pro users unlock AI-generated title variants, 20+ tags with individual demand scores, competitor analysis, and the Tag Gap report.

Understanding Your SEO Score

Your score is a number from 0 to 100, calculated across three dimensions. Each dimension is weighted based on how much it actually influences YouTube's ranking algorithm.

A score below 50 means you're leaving serious discoverability on the table — your metadata isn't giving YouTube enough signal to rank you competitively. Scores of 70+ typically indicate well-structured metadata. Above 85 means you're optimized at the level of top-performing videos in the niche.

Reading the Title Suggestions

Pro users receive three title variants generated for their specific video. Each variant uses a different formula from Guide 2 of this series:

• Variant A — Curiosity gap formula. Teases the payoff without fully revealing it.
• Variant B — List or ranking formula. Works well for "top X" and comparison videos.
• Variant C — Direct keyword lead. Maximum search relevance, clear and descriptive.

All three variants include your primary keyword in the first 50 characters and stay within the 50–70 character sweet spot. Pick the one that feels most authentic to your voice. Don't blend them — a Frankenstein title from three formulas usually reads awkwardly and performs worse than picking one cleanly.

Applying Your Tags

The tag list generated by the optimizer is already ordered broad to specific, matching the three-tier structure from Guide 3. To apply them:

1. Click "Copy Tags" in the optimizer
2. Open your video in YouTube Studio
3. Scroll to the Tags field and paste
4. YouTube will automatically parse the comma-separated list into individual tags

If YouTube Studio shows a character count warning, remove the last 1–2 tags in the list — those will be the most niche-specific ones, and you can add them manually once you've trimmed down.

Using the Description Keywords

The description keyword checklist is a list of terms the optimizer identified as high-value for your video — based on your title, tags, and what competitor videos rank for. Do not copy-paste this list directly into your description. YouTube's spam detection recognizes raw keyword lists, and human viewers find them off-putting.

Instead, use the checklist as a writing prompt. Before you save your description, run through the list and verify each term appears naturally in at least one sentence. If it doesn't, find a natural place to work it in.

Competitor Analysis (Pro)

The competitor analysis feature shows you what the top 5 ranking videos for your target keyword are doing with their tags — compared to what you're doing. It surfaces two key reports:

• Tag Gap — Tags your competitors are using that you're not. These are terms already proven to drive traffic for this topic that you're currently missing. Add the ones that genuinely apply to your video.
• Already Competitive — Tags you share with top-ranking videos. These confirm you're in the right content neighborhood. Keep all of them.

The Tag Gap is where most of the value lives. If every top-ranking video about a specific coaster uses the tag "coaster enthusiast" and you don't, you're missing a connection to an audience that's clearly watching similar content.

The Pre-Upload Workflow

Build this into every upload and SEO becomes a habit instead of an afterthought. The whole process takes about 5 minutes:
