Length checks for social captions, ad copy, email subject lines and meta descriptions.
For marketers who would rather not context-switch between UTM builders, link shorteners, character-count pages and an AI tab. The day-to-day tools: tagged campaign URLs that survive the round-trip from spreadsheet to ad platform, character counts that match the platform limits, a slug generator for landing pages, and the AI summarizer / translator as the lingua franca for inbox triage and localization QA.
On nearly every platform, yes - which is why the count climbs faster than you expect. The counter shows characters and words side by side so you can match whichever rule the platform states.
Long enough to read as a sentence and short enough not to be cut off - around 150-160 characters is the usual working target. Search engines rewrite them often, so treat it as a suggestion aimed at the person scanning results.
Most feeds truncate after a couple of lines and hide the rest behind a tap. Front-load the hook, then check where the cut lands on a phone rather than in a desktop preview.
