After editing in Etsy, reopen the listing and check that your title, tags or description saved correctly.
If Marmalead still shows the old version, confirm the active shop and listing, then refresh the page. A delayed display doesn't mean Etsy rejected your edit.
When should I check the results?
Give the listing time to receive visits. A quiet item may take longer to show a useful pattern than one with regular traffic.
There isn't a fixed number of days that proves a keyword worked. Look at visits and orders in Etsy Stats, and allow for seasonality, ads and stock changes.
Keep your old wording and edit date. The results guide gives you a simple way to compare.
If Marmalead continues to show the wrong text, choose Help → Contact Us. Include the affected listing, when you edited it and which wording you expected to see.
