Again, I'm new to all of this so sorry for the beginner questions. I'm using the WC3 Validator Markup Validation and I'm coming up with 43 errors. A lot of these errors are ALT tags in images not set up. First question, do I really need ALT tags in all of my images? Say I have an image that is pretty much a spacer, can I put some keywords in there and not be picked up for spamming? I've been trying to research the DOCTYPEs... what is the real difference between Transitional and Strict? Since I don't have a DOCTYPE on my one page, is this why I'm getting some of these errors... there is no attribute "WIDTH". …application/x-shockwave-flash" width="968" height="376"></embed>
First, you need to set the correct document type to get the "real" errors since each one will provide different errors with differrent html tags, start your research below... http://htmlhelp.com/tools/validator/doctype.html Yes, alt tags on all imagines are required in the standard.
Ok I understand about DOCTYPEs now but I still have a question about validation. What are your opinions on validating a site? Do you think having errors on the site will hurt your chances of ranking higher in search engines and if not, do you think that would possibly be something the search engines look to in the future?
