Hey, very nice work! I just looked at a few pages and see that it's working. You are going to have to watch the stats and let us know if you see a difference?
If you are not happy with the results, I have two suggestions:
1) I would not use the same static text in the keywords. It's too easy to spot and get filtered for. The best thing to do is just parse out some of the title and description and use that, or
You could also put together a fairly large list of keywords for the tag, and set it up to rotate them at random.
-domains, keywords, parking, sell domain
-domain host, domain parked, appraise domain, registration fee
-monetize domains, Names Lot forum, hosting, scripts for sale
I'm not crazy about this idea since you will get keyword usage that is not on the page, BUT I don't think that is a huge problem since I think the keywords tag is intended for the most important words, and also things that the page is about, but cannot appear on the page, like misspelled words.
2) You could try using more of the description, up to about 200 characters. I set a limit of about 250 for this tag, so I don't think using more will hurt.
