Ah, dead website syndrome. The answer is, wake it up!
Is your website looking tired and forlorn. Sitting in the Google basement where no one ever sees it? When was the last time you looked at it? Once upon a time it was possible to build a website, put the right keywords, descriptions etc into it and forget it and it didn't make much odds to it's performance.
Not anymore, now your website has to be bright eyed and awake, full of new and relevant information, pictures and more. You need your website to be an ongoing party with lots of visitors, then you'll really start seeing the results. Building the website is the first small step, you'll probably need help with the rest.
