Your HTML is not valid.
Ads take up half the homepage.
Capitalize, looks way more professional.
Add a little more content to homepage.
But the first thing I'd do is get your HTML valid, then check if your CSS is valid.
Hi tabish3, here is what I would do.
1) Your left sidebar's length is way to big. Might want to change the CSS on that or your code might not be valid.
2) Capitalize, it really helps. Also, try not to put "Welcome to XYZ" in the title, it seems like you are not getting visitors and this is the only way.
3) half of your homepage is ads. Try cutting down if possible on that.
Those are my suggestions.
Wow umm, I personal think you should start over use Joomla! Find a nice "Fun" fitting template and make sure the colors aren't plain it makes a page look flat. Take a look at my website, look what ive done: http://xerogi.co.nr/
