You shouldn’t have to redo your meta tags by hand there are plenty of free programs out there that will do them. I think I paid $39 for one that generates the meta keywords tag automatically by pulling keywords from my page and then it inserts it right onto the page for me. It’s by Hermatic and it’s Keyword Meta Tag Generator, they also have a freeware version. That program was such a life saver for me that they put up my testimonial on there site, lucky for me, free advertising is hard to come by.
