YouTube Title & Description SEO Checker

YouTube Title and Description SEO Checker

Use this free YouTube title and description SEO checker to review metadata before publishing a video. Enter a title, description, target keyword, and optional tags to see length limits, keyword placement, repeated words, chapters, hashtags, links, calls to action, readability, and a combined writing score. The analysis runs locally in your browser and does not claim to predict rankings.

Check YouTube Title Length and Clarity

YouTube currently allows video titles up to 100 characters. A valid title can still be difficult to scan when the most useful words appear late or the phrasing is repetitive. The checker measures total length, flags very short or near-limit titles, identifies duplicate words, reviews capitalization, and shows an approximate search-style preview. Search interfaces can truncate text differently by device, language, query, and layout, so the preview is a planning aid rather than an exact reproduction.

Review Target Keyword Placement

Enter the main phrase that accurately describes the video. The tool checks whether it appears in the title, whether it is reasonably close to the beginning, and whether it appears naturally in the description's opening. YouTube recommends identifying one or two main words that describe the video and featuring them prominently in both the title and description. Keyword placement should clarify the topic for viewers, not produce awkward repetition.

Analyze the First Lines of the Description

The first part of a YouTube description is important because viewers see it before expanding the rest. This checker previews the opening 150 characters, checks for the target topic in the first sentence and first 25 words, and measures the full description against YouTube's 5,000-character limit. Put the video's specific promise and context first, then add chapters, related resources, credits, and other details below.

Check Hashtags, Links, Calls to Action, and Chapters

The description analysis detects hashtags, URLs, common calls to action, and timestamp lines. YouTube may show up to three engaging hashtags from the description near the title, but unrelated or excessive hashtags can reduce clarity and violate metadata policies. For manual chapters, the first timestamp should start at 00:00, at least three timestamps should appear in ascending order, and each chapter should be at least 10 seconds long.

YouTube Tags and Relevance

Paste comma-separated tags to find duplicates, measure the combined character count, and compare them with the target keyword. YouTube states that tags can help with common misspellings but otherwise play a minimal role in discovery. Treat them as a small metadata aid, not a substitute for a clear title, useful description, accurate thumbnail, strong content, and satisfying viewer experience.

Power Words and Curiosity Signals

Numbers, specific outcomes, questions, brackets, and familiar formats such as “how to” can make a title easier to understand. The tool reports these elements as curiosity and clarity signals. It does not reward misleading clickbait, sensational claims, or excessive capitalization. The best title sets an honest expectation that the video fulfills.

Compare a Competitor or Alternate Version

Paste another title and description to compare the same visible checks side by side. This can be a competitor example or your own second draft. The comparison does not access private analytics, search volume, impressions, click-through rate, retention, or channel authority. Use it to spot clearer phrasing and missing metadata, not to copy another creator.

Preview Desktop, Mobile, and Thumbnail Context

Switch between desktop and mobile preview widths and optionally load a thumbnail image from your device. Seeing the title beside the thumbnail helps you notice duplicated wording, weak topic cues, or a mismatch between visual promise and text. The thumbnail stays inside the current browser tab and is not uploaded by this tool.

Save Title Variations and Export a Report

Save multiple title drafts locally for a simple A/B planning workflow. Each saved variation keeps its score and can be restored for editing. Copy the analysis summary or open a print-friendly report that can be saved as PDF through the browser. Saved drafts use local browser storage and are not synchronized to an account.

Use the Score as a Checklist, Not a Ranking Prediction

The 0–100 result combines transparent title, description, keyword, chapter, hashtag, tag, and readability checks. It cannot measure video quality, viewer satisfaction, click-through rate, watch time, competition, personalization, or recommendation-system signals. A lower-scoring draft can outperform a higher-scoring one when it matches viewer intent more honestly. Review every suggestion in the context of the actual video.
