Ok Good. Your site is nicely made. But the SEO is not so good.
1) Go here http://freekeywords.wordtracker.com/?seed=jokes&adult_filter=remove_offensive&suggest=Hit+Me
and see for keywords. You are only targeting single word keywords, not so good for SEO. It should be like funny jokes, adult jokes and like that.
Do NOT use so many commas in Title tag. The best practice by professional SEO's is to keep the title up to 65-70 characters with spaces.
2) Keep the keywords in meta tags up to a maximum of 6.
3) None of your keywords are in bold, it adds wieght to SEO. Add bold and underlines to keywords, don't overdo it.
4) Add sitemap
5) Very weak off page optimization. Do link building, directory submission, article submission. Search for good link partners. Forum submission. Search for Quality.
6) I am personally a SEO Consultant and on doing the above things correctly, it will reward you with high ranking for your keywords.
Hope that helps. Thank you.
