We plan to be a specialist site selling merchandise that often won't be widely available but also, that people looking for these products will most likely not know model numbers or even the correct product name.
If we become known for the niche that we are aiming for (and which we feel confident that we will achieve), we are concerned that many customers will use us as the first website to look up or search for the item they are looking for, by looking at product categories.
Then with the model/product number or name, they search for the item on Google, Amazon or Ebay.
Is there any way to prevent that from happening to any extent?
I appreciate that not everyone will do this and also, that products may not always be available elsewhere.
