While running the validator and getting it to validate your page itself will not be an issue since the W3 Consortium's validator is not only free, it doesn't even have to be installed to be used , the problem comes when the validator checks your page and tells you that there are errors.

If you have no knowledge of HTML and CSS, you will probably have some difficulty figuring out what those errors mean, whether they are serious, and how to fix them. If you are using an editor like Microsoft Expression Web , Dreamweaver , BlueGriffon or KompoZer , you can usually assume that the code they produce on their own is valid.

From my limited experience mainly creating demo sites for the purpose of writing tutorials or reviews for thesitewizard. com , these four editors seem to create correct HTML and CSS code. This means that if you get errors when you validate your page, the problems must come from elsewhere.

If you have inserted code that you obtained from a website such as if you have added a Youtube video to your page , it's possible that the code is the source of the error message.

Alternatively, if you have modified the code on the page manually, the error may have crept in there. Having said that, sometimes the error is benign. For example, if you have added XHTML code to a page that has HTML, you may or may not get validation errors since you are mixing 2 different HTML families that have slightly different conventions.

As far as I can tell, for the most part, this kind of error does not cause any problem for either browsers or search engines.

Another way is to search the Internet for the solution. For example, you can copy and paste the error message given by the validator into a search engine, and see if there are any websites out there that talk about this particular error.

This may not be as fantastic an idea as it first appears, since their solution may be too general to be helpful for your specific problem, unless the error message is the result of your pasting code from some popular source like Youtube or something of that level of popularity.

A third way is of course to ask someone, whether it's someone you know personally, or someone on the Internet. This solution also has its own issues, since you may get a solution that creates a bigger mess of your page than it had in the first place.

It all boils down to their competence and willingness to spend enough time figuring out the problem. Finally, you can also ignore the problem. If you want to do this, you should test your web page in as many web browsers you can to make sure the error message does not diagnose a problem that causes visible issues.

If you find that your site seems to work fine in spite of the error, you may decide to just ignore it and hope for the best. Although this solution is not ideal, you may be forced to take it if you can't find an alternative. It's not ideal because the error may bite you later when you least expect it, for example, when there's a new version of some web browser that chokes on the bad code.

It may also cause problems in a non-visible manner, such as in the way the search engines index your page. Some people validate every time they make a modification to their pages on the grounds that careless mistakes can occur any time.

Others validate only when they make a major design change. I always validate the template for my pages when I make a major design change. I try to validate my pages each time I make modifications, although I must admit that I sometimes forget to do so with the occasional disastrous consequence; Murphy's Law doesn't spare webmasters.

I find that having an offline validator helps to make sure that I remember to validate: having to go online just to validate my pages tends to make me put off validation till later, with the result that it'll occasionally get overlooked. For those not familiar with the terminology I use, when I say "offline validator" I simply mean a validator that I can download and install in my own computer so that I can run it on my pages without having to go to the W3 Consortium's website.

You can find offline validators on the free validators page I mentioned earlier. The HTML Tidy validator listed on that page is available for numerous platforms including Linux, Mac, Windows, etc and has proven helpful to many webmasters the world over.

As I mentioned above, it's generally a good idea to validate your web page. It will point you to errors that may affect how your website is understood by web browsers and search engines.
