The main ones to remember really are: Media Language-connotative meaning, signs, iconography, music, lighting, camera angles, mise en scene, editing etc.. Institutions- who produced it? what influence this has on the text? Genre (if relevant)- talk about codes and conventions assoicated with it etc... Rrepresentation- who? what? where when? why? is it accurate/ biased/fair? Audience- who its aimed at? made for? mode of address? Audience theory can be brought in here i.e. the uses and gratification theory Ideologies and values- ideas and beliefs that underpin the text, values of society Narrative- texts structure e.g. could use Todorov Theory which is the equilibrium, disruption etc... also discuss character roles and themes that arise.
Then you could discuss the effectiveness of the text along with the preferred meaning, this could fit into what you write about audience.
I always find these useful to follown when writing an essay and particularly just found it useful to remember MIGRAIN for my AS last year.
