Hello friends, What happen if we cross the limit of characters for keywords, title and description tag can we penalized by search engines ? Thanks
The world shall end. - Joke. Search engines tend not to take much notice of them these days, they are really there to give a short description of the page, so you shouldnt really need to many keywords or a long description. It is possible that some search engines can penalize you, but it wont be greatly as they are not real key factors in your page ranking these days.
Even yahoo don't take into account meta tag characters, google stopped it years ago because of abuse, so don't pay much attention to them - as steammultimedia says, there's really don't have an impact any more
