While I agree that CTR is not the end result, it does give a measure of interest. What I would suggest, is completing your profile in order to give consumers a bit more information about you. Basically you need to market yourself such that consumers want to click thru to your website. I have about a 9% CTR, which I would attribute to several factors:
1. I actively participate in theTrulia Voices forum. One thing I would stress to you, is that these forums should not be used for self-promotion. Just answer the questions with the consumers' best interests in mind, and not be self-serving.
2. I have a complete profile. May not be the best profile, but at least I am transparent and authentic to the consumers.
Now, all I need to work on is the retention rate on my website and blog. gotta work on that content....
Best of luck to yoou!
Right now you've got a 1.2% clickthrough rate - which in all honesty isn't so bad in the grand scheme of things. Essentially trulia is nothing more then a giant ad-banner for listings. You have absolutely no way to target your audience beyond a general "people interested in real estate", so you're working off of a very broad base. Given that 1.2% is actually pretty good.
Ultimately - I wouldn't worry about CTR too much. It's really kind of an out-of-date metric, and is really only used to calculate advertising costs, not actual results. Especailly given the amount of info on Trulia, those 78 viewers who didn't click through to the listing, probably felt they got enough information about the property.
