When you're stuck on a listing's wording, Boost SEO gives you a title and tag set to start from.
Try it on one listing
Open My Listings and choose an item.
Select Boost SEO and wait for the suggestion.
Compare it with your current title and tags.
Use Copy to take the wording you want. Run again asks for another version.
Keep what fits your product
Does the title clearly name the item? Are the material, color, size and options right? Keep useful wording from your original.
Use up to 13 tags, each no longer than 20 characters, including spaces. You don't have to accept the entire suggestion.
Read the numbers as keyword research
The before-and-after searches and visits describe the keywords' market activity. They are not extra visits promised to your listing. Some phrases can reach the same shoppers.
If a phrase seems odd, look it up in Keyword Search or ask Marma why it was suggested.
Save your original wording, make your chosen edit in Etsy and save there. Boost does not publish it for you. Keep a simple record of the change.
