YouTube Title and Description Checklist: Make the First Lines Count

Your title and description are the first explanation viewers get of a video outside the video itself. A good title makes the subject clear and gives the right viewer a reason to click. The opening lines of the description add context before someone expands it.

YouTube allows titles up to 100 characters and descriptions up to 5,000 characters. Those are ceilings, not targets. You can draft and count both with the free YouTube Title & Description Checker.

Start with the video, not a keyword list

Write down what the video actually answers or demonstrates. Then describe that promise in plain language. A keyword is useful when it names the subject viewers are looking for; it becomes awkward when it makes the title vague or overstuffed.

YouTube recommends identifying one or two main words that describe a video and featuring them prominently in its title and description. Its description guidance also recommends unique descriptions and using the opening lines to explain the video, since that is what viewers initially see.

A title checklist

Before publishing, check that the title:

• Names the specific subject, question, or result.
• Sets an expectation the video fulfills.
• Places the key phrase naturally near the beginning when that reads well.
• Fits within 100 characters and remains clear when shortened on smaller screens.
• Avoids claims, certainty, or urgency the video cannot support.

There is no universal ideal title length. Aim for a title that communicates the idea before it gets truncated, not one padded to use every available character.

Write the description opening first

The first couple of lines should make sense without a click on “more.” Tell the viewer what the video covers and what they will get from it. Include the main topic in natural language, then add details that help: chapters, relevant links, credits, and channel information.

Do not paste the same generic paragraph into every upload. YouTube recommends a unique description for each video. Make sure any links, timestamps, product mentions, or claims in the description match the final edit. The full field has a 5,000-character limit, but a long description is not automatically a helpful one.

Use a simple final review

Read the title and first two description lines as if you had not seen the video. Can you tell what it is about? Would the title still be accurate if you removed the thumbnail? Does the opening description add useful context instead of repeating the title word for word?

Then check spelling, names, links, chapter times, and character counts. The metadata checker can count the title and description and check an optional focus phrase. It does not predict ranking or viewer response; use it for mechanical checks, then use your judgment for clarity and accuracy.

Common traps

Writing for a score instead of a viewer. A keyword tool can suggest terms, but it cannot know whether a title accurately describes the finished video. Keep the promise honest.

Hiding the useful information after “more.” Put the subject and value in the opening lines. Save secondary links and channel boilerplate for later.

Repeating phrases unnaturally. If the title and description read like a list of search terms, rewrite them as normal sentences. Clarity is more useful than repetition.

Forgetting the finished edit. Titles and descriptions are often drafted early. Review them again after the cut is locked so the copy reflects what the video actually contains.
