Hi I have a niche Etsy site (https://www.etsy.com/uk/shop/DomesdayExtracts) selling twon / village listings from the Domesday Book (commissioned by William the Conqueror in 1085). My ideal customers are people with an interest in local history of the period - could also be a gift. I suspect our audience will have a connection with one or more of the 6,000 towns and villages listed eg a local resident / former resident or a relative researching their family tree. I have someone researching keywords currently. I am looking for some to advise on which platform to advertise on (eg Etsy? FB? Instagram? Others) and to help set up and run a test ad campaign. Is there a sufficiently large audience to generate interest and sales. I'd also like to know budget I could test the market with. Thanks
