hi , is google looking to valid on page ? for listing if isnt what the "valid html optimizition" be useful with out same showing on all browsers? thanx 4 answers.
If the search engine spiders can't read your website (i.e. the code is really broken), then they won't be able to index it. Yahoo have recently changed their algorithm to include quality factors, e.g. compliance.
We noticed a slight improvement on Google after tidying up our html. You can validate your html here for free: http://validator.w3.org/check?uri=h...etect+automatically)&doctype=Inline&verbose=1
Yep I have read the exact same thing about the new Yahoo indexing algorithm. I do not have a link for it and believe it has not yet been implemented.
although many may not agree, but it does seem to help with the rankings. A little quote from my website. "A website built to comply with the W3C Standards make web documents more accessible to all types of users and machine agents, and more visible to search engines. Rankings are often dramatically higher, and in no case have we seen rankings drop after conversion to standards. Likewise, the summary information provided by the search engine is more likely to display meaningful content from the document". If you have a small website and the time to do it, then go ahead and make it valid, it will not hurt in any way. Besides, I like to show that my site ranks #2 for the keyword "W3C Validation Services" on google. Is this because the page is valid, maybe, maybe not, and sure the keyword is not really that competive, but it sure looks good.
