Google Attributes (Business Profile)
Google attributes are selectable features in a Google Business Profile that describe characteristics of a business – such as "wheelchair-accessible entrance", "outdoor seating" or "women-led" – and make the listing eligible for specific search filters.
In practice
It pays to review the available attributes regularly, because Google keeps adding new ones – this often opens up additional relevant search filters with no further SEO effort. Only select attributes that genuinely apply to your business. Not every attribute is available everywhere: Google states that some can only be changed in certain locations, certain countries or certain business categories – so what your own profile offers is what counts.
