The following guidelines for tagging ads with keywords will help you sell your stuff faster:

• separate tags with a comma
• a tag should almost never be more than two or three words
• tag with both specific and general words like “swimming pool” and “pool”
• use singular rather than plural (leave off the “s” at the end) unless its necessary for a word like “parts” or “plants” or you would normally search for the plural form
• don’t use punctuation
• always tag breed & features that are likely to appear in other ads
• limit to about 3 to 5 tags
• don’t tag common words that aren’t specific to your item
• capitalize the first letter of proper names and brands
• double-check your spelling
• don’t use all caps unless it’s an acronym
• also tag abbreviations such as “VW” for “Volkswagen”
• tag with “wanted” if you are looking to buy something
• tag with “trade” if you are willing to trade
• tag with “free” only if the item is truly free without having to buy anything else
• don’t repeat the category in the tags
• tag colors, materials, etc.
• don’t tag locations if you have already entered them in a location field
