Etsy Tag & Title Checker
Free tool from the Etsy 1% Toolkit. Checks your title and 13 tags against Etsy’s limits and title guidance.
Tip: you can paste your tags straight from Etsy.
Limits from Etsy Help: titles up to 140 characters (Etsy suggests under 15 words), up to 13 tags of up to 20 characters each, using letters, numbers and spaces. Apostrophes and hyphens are allowed inside a tag, but a tag can’t start with them. Nothing you type leaves your browser.
