Im sure this may be a stupid question but how significant are the results of
http://validator.w3.org in terms of every thing? Are the guidelines of W3 the be all and end all of websites,
SEO and indexing pages? Or is W3 just guidelines for better practice and cleaner code as the web becomes more complex?
When I first saw all the errors returned I was quite worried, so I tested a few other sites including the following to see what results they returned
www.amazon.com 1102 errors
www.walmart.com 132 errors
I was surprised to see that the sites listed above show so many errors due to the size of their business.
If errors are shown when validating in the W3 validator does this mean that sites can not be indexed if they return errors? Do the errors such as
""&": this may be valid in some contexts, but it is recommended to use "&"
make sites rank lower?
Stop search engines indexing pages?
If the individual errors returned are not so significant in the overall ranking and indexing of websites,
what is the biggest single most important lesson of W3 vallidator results that we need to be aware of?
As for the
SEO-Browser.com I dont know what info I should be looking at to be worried about?
