Secluded location- There are a range of locations that directors can choose for the setting of their horror film, places where there will be no signal or no one else around to help. Such as ghost towns, haunted houses, cave, fields or the woods. To give the audience the feeling of lonlieness. A good example of this is

Power cut/ Phonelines are cut-
This is a typical convetion either the 'killer' cuts off the line, or the victims battery runs out on their mobile phone. This is to create the sense of helplesness and also to show the audience there is no way out and no one to help them e.g family, friends or the police.
Flash back/forward in time-
This is to give the audience the general idea of what the film is about were its set and normally the reasoning behind a haunting or how a certain location became the way it is.
Forgetting the threat-
Horror fims usually contain characters that seem to forget a threat which is among them, this is mainly used in teen horror films where a moment of distraction is used and a scary noise draws the characters attention towards the threat. This ia normally used it modern horror films as its a good effect to the film as it grips the audience's attention.
Avoiding Escape-
When death or danger occurs in an inside place, chracters normally run upstairs then out of the front door either due to them forgetting or the front door is locked. Normally the victim will run into a bedroom/bathroom where there is a lesser chance of survival. In these situations chracters tend to hide behind doors or crouch behind a window giving the killer an easier way in which in turns puts the character in more danger this makes the audience anxious and using some scary tension building moment can be a very significant part in the film.
