Now you can easily identify which trait has the highest floor on your NFTs. This option is available under the About tab on the NFT details page. Each property shows the lowest price for NFTs with this trait, count and overall percentage. Bear in mind that these floor prices are specific to LooksRare and won't count the date from other marketplaces.
Apart from this, a popular extension TraitSniper now also supports LooksRare listings. It simply shows rarity and floor prices for all NFTs that you see around on LooksRare as well as on OpenSea. It ends up quite useful if you want to buy a rare underprices token.
