Free youtube description generator for a stronger first draft.

Whitcombe Bikes is a two-mechanic workshop that films short repair tutorials. The video is eleven minutes on why a dropper seatpost slips and how to service one at home. The inputs to the description are the video's actual promise, the viewer it is for, the chapters, and one thing the workshop would like to happen next, which is that local viewers know the shop will do this job for them.

The first two lines carry everything, because roughly the first hundred and fifty characters are all that show before the more link: 'A slipping dropper post is usually air, not a broken cartridge. Full home service in eleven minutes, with the two tools you actually need.' That sentence names the problem in the viewer's words, states the outcome, and sets the time cost, and it reads sensibly in the places where descriptions appear beside the title.

Below the fold the body opens with two short paragraphs: which posts this applies to, and the honest limit, that a cartridge with damaged seals needs replacing and the video will show how to tell. Then the chapters, starting at 0:00 and rising in order: 0:00 What slipping actually means, 0:48 Tools, 2:10 Removing the post, 4:35 Bleeding and re-charging, 8:20 Reinstalling and torque, 10:05 When to replace instead. Then a short list of what appears in the video, the torque figures written out as text so people can find them without scrubbing, and one line saying the shop does this service if a viewer would rather not.

What makes this hold up is that every part is doing one job. The visible sentence sells the click to somebody who already has the problem. The chapters turn an eleven minute video into six that can be entered anywhere, which changes how the video is actually watched. The torque figures in the text answer the question people would otherwise ask in the comments. And there is one commercial ask, placed after the useful material rather than in front of it.

The weaker version is the one most channels publish: 'In this video, we show you how to service your dropper post. Thanks for watching! Don't forget to like and subscribe. Follow us on Instagram, Facebook and X. Check out our website for more. #mtb #bikerepair #cycling #dropperpost #bikemaintenance'. The two visible lines have been spent restating the title, which the viewer can already read directly above. There are no chapters, so the eleven minutes stay a single block. The links are generic and none of them is the one that matters. And the tag pile at the end does nothing except make the small share of viewers who expand the description read something written for nobody.

Do not spend time on the description when the video itself is the problem. Nothing written below the player rescues a video that loses people in the first thirty seconds. If the retention graph drops sharply at the start, the work is in the opening, the title and the thumbnail, in that order. The description is a supporting element, and polishing it while the video underneath goes unwatched is effort spent in the wrong place.

Skip the long treatment for Shorts. The vertical format shows very little description, viewers are almost never expanding it, and a full body of chapters and links is invisible work there. One clear line and nothing else is the appropriate amount. The same goes for anything unlisted or private, such as a client review cut or an internal recording, where the audience is one person who was sent the link.

Do not write a description that promises what the video does not deliver. The first line is a contract, and overstating it buys a click followed by an early exit, which is the pattern that hurts a video most. If the honest description of the video is thinner than you want it to be, that is information about the video rather than a writing problem, and the fix is to reshoot or to change the title so the two agree.

Hold off on links until there is somewhere worth sending people. A description pointing at a homepage rather than a specific relevant page adds a step and loses most of the traffic in it. If the page you want to link does not exist yet, publish the video with a good description and no link, then add the link later, since descriptions can be edited at any time without republishing. The same is true of an affiliate or sponsorship block: get the disclosure requirements right before it goes up, not in an edit two weeks later.

The field takes up to five thousand characters, and it behaves as two separate pieces of writing. The first roughly one hundred and fifty characters appear above the more link on most layouts, and that portion also travels: it can surface in search results and in places where the video is embedded or shared. Treat it as a single sentence that restates the viewer's problem and the outcome, and do not open it with the channel name or a greeting, since both burn the only guaranteed space you have.

The body below the fold is read by a small minority of viewers, which is not an argument for filling it with keywords. It is an argument for putting things there that a motivated viewer specifically wants: the figures, the part numbers, the links to what was used, the correction you had to make after publishing. Keep paragraphs short, since the expanded description is read on a phone in a narrow column, and put the standing block of social links and boilerplate at the very bottom where it cannot get between the reader and something useful.

Chapters are the description element that visibly changes the player. The platform generates them from timestamps written in the description when the list starts at 0:00, runs in ascending order, and meets the minimum requirements for how many chapters there are and how long each one lasts. Get any of those wrong and the timestamps stay as plain clickable links, which still helps but does not produce the segmented progress bar.

Write chapter labels as descriptions of content rather than as structure. 'Removing the post' is findable; 'Part two' is not. Aim for the natural sections of what you filmed rather than an artificial even split, and resist making them too granular, since a bar chopped into fifteen slices is harder to use than one with six. For a tutorial, one chapter per step is usually right. For an interview, one per question or topic. Adding chapters after publishing is a normal edit, so a video that has picked up an audience is worth going back to, particularly if the comments show people asking where a specific part is.

These four are often written as one lump and they are not interchangeable. The title does the persuading and competes in the thumbnail grid, so it carries the strongest wording and the tightest character budget. The description explains and equips: it is where the detail lives that would make a title unreadable. Putting title-style hype in the description wastes the space, and putting description-style detail in the title loses the click.

Tags carry very little weight and are best used for genuine variants and misspellings rather than as a keyword dump. The pinned comment is the underrated one. It sits directly under the video where everybody sees it, it can be changed at any time, and it is the right place for a correction, a follow-up question to draw replies, or the single link you most want clicked. If something is genuinely important and time-limited, the pinned comment beats the description body for visibility, and using both for different jobs is better than repeating one in the other. Decide which of the four carries each piece of information before you write any of them.

Descriptions are editable indefinitely, and that makes them one of the few parts of a published video you can still improve. A week after publishing, read the comments and look for the questions people ask that the description could have answered: a measurement, a product name, a step they could not find. Add those to the body, and add or fix the chapters if the questions are about location within the video.

Then keep a maintenance habit for the older videos that carry on getting views. Links rot, product pages move, prices change, and a description pointing at a dead page on a video still earning views every week is a steady small loss. Correcting a factual error is better done in the description and a pinned comment together, clearly marked, than left for the comments to argue about. When you have several videos on related topics, going back to add a link between them is worth more than most new work on any single description, because it gives the person who has just finished one video an obvious next thing to watch.
