Hi Tracy, Hi Hofmar - nice to see you both back in the forums.
Tracy I've had a look at the source code of your site and your meta tags look pretty good.
I can see you only have the 6 keywords but I would not worry about this -
Google does not use meta keywords at all. So you are not missing out on anything here - to see why your Joomla is only displaying those keywords I'd have to log in and have a look at your site.
Something that would help you a bit more would be tweaking your page title tag - I've just done a little
keyword research and I think by optimising your site for
technical drawing services you could do quite well... Have a play with that tool and see what it comes up with - Title tag is the most important meta tag and by including keywords in this that get searched for - and relate to your services - you can bring customers to your site that will convert well.
