Over at Wolf-Howl, Michael Gray tackles the question: Can W3C compliance and accessibility impact your Search Engine Optimization?
From my experience having a site that is 100% code compliant doesn’t give you any SEO benefit. That said throwing up a page with complete disregard for valid code is looking for trouble.
If you put your page into a validator and it comes back with hundreds of errors you may be looking for trouble.
Depending on what your errors are you may have made it harder for a bot to crawl your website.
However if you can get it down to handful of errors, it might not be worth the time obsessing over those last few details.

As far as Google optimization is concerned, Adam Lasnik has just confirmed that they pay absolutely no attention to W3C compliance in their algorithm.

Matt Cutts has also confirmed that Google does not look at compliance when it comes to ranking pages.
I am not surprised, considering that google’s pages do not validate, it would be surprising if they enforced it upon others.

Validating code may not affect your SEO, but I definitely agree with Graywolf’s comment about mobile devices. If starting a new site from scratch I would recommend XHTML Strict that validates and that takes into account the possiblity of being viewed on mobile devices.

I do a lot of training for people that want to do SEO themselves, and the best way to describe how search engines read a web page is an analogy: Search engines read your web page like a college professor reads a research paper.
