“Are directories worth it, well the traffic counter on my website says I've had 0 visits in 2 months due to online ads...
Some tell me it takes 6 months some tell me waste of effort...”
Before this turns into a general directory bashing thread, (as we are a directory) that's not strictly true, as I can see you have had some click throughs from us.
You are displaying a Google Analytics code in the clear (for some reason) UA-50151694-1. So assume you are looking at your analytics's, and this will tell you exactly where your traffic is coming from. Search Engines, referrals, social media, websites, forums etc.
You will also be able to see your bounce rates, see the user journey and get an idea what does and doesn't work. Don't just pursue one method of marketing and sit back. It's a continual process across a broad range of channels. Be selective, you don't want to be listed on a whole range of low value directories, but you do want to be listed on a number of directories.
These will give you something called "citations", Name, address and phone number. ie pointers to Google that you are who you say you are, regardless if you have a link or not.
But the main thing is make sure your landing page is the best it can possibly be, and you will get all this data from your analytics. If you don't understand or can't make any sense of it, then learn. It's one of the most important marketing tools you have, and it's free 
If people land on your home page, and then bounce away, then the reality is people don't like it. If you have a low bounce, lots of pageviews and time on site, but people still aren't buying your products, then they like the home page, but something on the product page is turning them off.
Likewise look at the quality of traffic coming from different sources. If all the traffic from a particular medium just bounces and does nothing, but traffic from another source converts well, then you know where to concentrate.
Generating and reacting to this kind of data is how you will move forward imho.
