You need to focus on the organic traffic, and make sure which keyword bring you traffic and type this keyword in Google search bar( Google could be the one, Or you also can try Bing and Yahoo), analysis what is your ranking, and is that possible come from the images. and then get idea how much bounce rate this keyword have.
Ok, if you get all information, next step is fix high bounce rate one. take my test website: uniware housewares Corp. as an example. when i check the discount housewares coupon on Google, it could be on first page, and it bring 8 unique visitor, but 5 of them are new, so 3 of them are return visitors( this 3 could place the order) and bounce rate is 71%, that means, most of the visitors just check one page and leave, So, that's Good for ranking? No, Google understand your website much more than you, because this kind of information, in another words, high bounce rate, could be useless url, after fix the page, the best way is add some attractive images and link to other pages.
I just try my best to optimize the page, because i have no idea how to did coding job, For your convenience, i list that URL to you. http://www.uniwarestore.com/discount_coupon.html
