After reading your comments, I visited your site and used some of your tools. Quite good.
I read in some articles that MSN allows up to 1024 characters in keywords. Some seo sites and experts recomend 750, some even 200. These are misleading.
Same is the case with description and title tags.
Then come the question of repetitions. Suppose you provide most of the services FREE and the word FREE appears at many places in a list of prices or services, will it not amount to spamming or repeating more than allowed number of times? Google says to write the pages as you would like your reader understands it and not for SE. Contradition?
I have too many keywords in the index page. I keep them to reflect what I have in my entire site, because the index page is a gateway to other pages. Should I change the title, description, keywords, etc for every page?

I am a newcomer. Please advise.
Thanks and regards
