For every 1000 people searching for somewhere to stay in Yorkshire only 500 will actually type "holiday cottage yorkshire", the other 500 will be searching for something else, could be 500 different search terms, "mountain biking accommodation yorkshire dales", "what's on in harrogate in april", etc.
Individually these search terms aren't worth much, but added together, these searches equal or exceed the simple "holiday cottage" - that's a lot of potential visitors.
Few, if any of these visitors are wanting to solely stay in your cottage, sit indoors all week commenting on how nice it is - finding accommodation is a means to an end, not the end itself.
Your guests are golfers, bird watchers, cyclists, walkers, attending weddings, vintage car enthusiasts, touring motorcyclists, fishermen, business people attending a conference, artists, photographers, history buffs, skiers, competitors in sporting events - the list is endless, they are coming to your region for a reason and need somewhere to lay their head.
To start this kind of search optimisation you need to be able to add more pages to your website - ideally one page for each subject.
