I have a website and when I use http://www.validator.w3.org/ to check it, it says I have about 160 errors or something like that. I have no idea what these errors mean or how to fix them. Can someone please help me because I'm hurting my search engine ranking by having all of these errors (that's what I've heard anyways). Or if you can't help me, can you tell me what I should do to get help please? Any help would be greatly appreciated. Thank you.
