Guide: AI YouTube Description Generator

YouTube description SEO that still reads human

The first 157 characters appear in mobile search snippets. Front-load your primary keyword and a one-line value proposition. Below that, expand with timestamps, resources and social links. YouTube indexes description text for search.

Hashtags in descriptions help categorisation but use three to five relevant tags, not thirty. Put the most important hashtag first. Timestamps improve watch time by letting viewers jump to the section they need.

Frequently asked about AI YouTube Description Generator

How many hashtags should a YouTube description have?+

Maximum three. YouTube will ignore all hashtags if you use more than 15, and the first three are the only ones that appear above the title on mobile.

Do timestamps actually help discovery?+

Yes. Chapters increase average view duration by giving viewers a way to skip to the part they care about, and they unlock the Key Moments search feature.

Should the description repeat the title?+

Lightly. Echo the main keyword phrase once in the first sentence, verbatim repetition reads as spam to the algorithm.

Where should affiliate links go?+

After the first 150-character SEO block, in a clearly labelled 'Links' section, with the FTC disclosure on the same line as the first link.
