In present there is no problem for that...Who knows, in next few months/years this may become an important for the SEO..so try to fix the errors...

Majority of sites i have checked shows multiple validation error. I don't know if this is of big importance in terms of SEO.

You have to fix the error first will help you in future.

Well as far I know its a good sign to have a error free site. It helps to fasten your website loading time and Fast Loading of a website is a Ranking Factor in Google Search Engine Algorithm.

So Go For it..

Perhaps indirectly. Better code makes for a generally faster site. And a faster site does influence your ranking, according to Google. Plus there's nothing wrong with having a well made site. Go for it dude.

Me has been found a lot of TOP websites with validation errors too, so it is hard to say if good validation will really help

W3C compliance is NOT an SEO factor to Google.

Actually it can be, and it probably means more that you realize.

If your code is compliant it shows that you have gone out of your way to create a properly coded page. I cannot help but think that with the emphasis Google is putting on quality lately that this is being unrewarded. There may not be a penalty for not doing it, but I suspect you get points for doing it.

More importantly, if your page code does not parse right, Google will misunderstand it.

Having said all that, at some point some pages cannot be validated, or can't be validated economically. Flash sometimes will not validate, and some old coding methods (<center> for instance) work fine even though they are now obsolete. It's just not practical sometimes to go into an old site and change all the centering to inline CSS.

What I do is validate as much as possible. There is no reason not to fix forgotten closes, and simple things like that, and affects the parse the most. It will also teach you a LOT about proper HTML.

No, it's not important. Well, at a very high level it's not. If you have validation errors, bots such as Google's will work through them. However you can't have just an all-out shitty coded site. If you have 2 head sections or tremendously bad markup, the bots might not be able to parse the pages.

I would not worry at something simple like using a deprecated tag or something like that.

(emphasis mine)

I understand wanting to launch and make money right away. The more you can fix in the here and now, the less you have to fix later. Do things right the first time, correct all the errors you can (if it's a server-level error and you don't have access to that, ask your host for help).
