There are validation error in my site. How can i correct them. Please tell me what should i do to make my site error free. There are some crawling errors also. Are these errors related to each other.....
The way to fix the errors is to write better HTML without mistakes.
Unless you give us more information, that's the most helpful response you'll get. Bear in mind that the validator usually tells you exactly what's wrong, so just follow the instructions it gives you with the errors and you should be able to figure it out for yourself. If not, let us know and we'll try to help.
If you use W3C for validation, there is an option Clean up Markup with HTML-Tidy where it might fix your errors.
I would avoid this. The validator merely guesses at what you wanted. Often time, it is wrong.
And also you don't figure out hte invalid HTML for yourself and thus you lose valuable debugging experience.
I did say might fix your error.
