Hi @Angela304
I must admit I didn't do a detailed review but skim read so I must have missed the bit about shops and cafes. Maybe emphasise this a bit more.
My day job is in comms and marketing and I can tell you the person who talked about aiming for a 20% conversion rate was talking BuXXXXXox 🙂 😞
There are lots of reasons people might look at your place - they maybe a competitor, they may just be looking around for something to come back to later in the year, they may have clicked on your listing by accident, it could you, family and friends making frequent visits. They could be other hosts having a nosey.
BNB doesn't do photography everywhere. If they don't do your area, you cold get in a local freelance who specialises in interiors - a single day at your place is likely to cover the cost of a half day shoot.
Good luck...I will add you to you to may wish list.. Cornwall is one of my favourites spots.
