Frequently asked questions

How much text should a thumbnail actually have?+

As little as possible — 2-4 words is the practical ceiling for something a viewer can read at a glance on a phone screen. More than that and it just becomes noise.

Should this text repeat my title?+

No — thumbnail text works best when it adds a different angle or emphasis than the title, not a shortened copy of it. Together they should tell slightly more of the story than either alone.
