Try not use templates. They aren´t really exclusive or original.
To increase the site´s visits you have to make a research about the target audience of your website.
Are they males or females? How old are they? What to they like? With things like these in mind you can come up with a layout that´s apelling to the visitors... =)
If you really want to work on that template, try to make it look fresher. Everything about it sounds like the internet in the 90´s... For exemple, the site seems optimized for 800x600 monitors. No one use those anymore... Make it longer, with more white space! =)
The design looks old fashioned, you need to spice it up a bit and make it look less cluttered
"Our services," "Welcome" and, "Access numbers." I feel lost, not knowing where to look or what to read first. I suggest finding a focus for the page. My feeling is that "welcome" has some higher significance then "access numbers" and "our services," especially to new visitors. I suggest that you find ways to create a focus/emphasis on the page. You could start by attempting to establish visual contrast between the different columns. You might also reserve red to the most important links.
The layout seems made in the begining of internet. It doesn´t tell us anything. Take a look at modern galleries websites, refresh!
The couch doesn't represent a conference call. I'd replace this with a conference room or something else to portray conferencing services.
Here are some concrete ways that I think you can improve your theme. 1) The main links in the left side navigation bar, 'confcentral', 'features', 'sign up', 'login' and 'faq' might look better if they were left aligned. Everything else on the site is left aligned so it would make the design more cohesive. 2) Rather than the couch image I would look for images that contain the following: people sitting around a conference table, telephones, conferencing technology, headphones, etc. Images with people will at least make the site more pleasant to look at. In doing a quick web search on 'conferencing' I got some ideas for imagery. 3) It looks like the site's mission statement or purpose is the 'unlimited conferencing anywhere, anytime' text. I think you could make this larger and more prominent. If you do that then you could add a slightly smaller and different colored font beneath that with some of the text from the first paragraph under the 'Welcome' title. Essentially call out the services of the site in the header image. 4) Lastly I'm not sure how much flexibility you have to change the code but if you can futz with the markup language and possibly make the site wider that would make it seem more modern I think. Since you are using a free theme you may be limited in what you can do to change it on your side, however little by little you can improve on it. I hope this helps you.
I think this will work for your purposes, but could be quite a bit more interesting. It is very basic and straight forward. If that is all you are looking for, then I think you are fine.
