HTML Validation

[Halfdeck]

How much, do you imagine, does the HTML validation of your pages effect SE bots and indexing. Or do you think that it plays no factor at all?

We can only guess. We don't know the extent to which the SE bots can correctly spider a page with broken HTML. The only thing I assume is the major SEs have no problems crawling/indexing a WC3 Valid HTML page -- but even that's a big assumption. I've written a few parsers using regexp and I'll say its not hard for a parser to choke on some random /unexpected stuff on a page. But the final answer to your question really is "we don't know."

If you're asking SHOULD I validate my HTML pages, my answer is yeah why chance it?
