i always ask , is that a relationship between higher Page rank and w3.org validation?? i test that on many sites. and see that is right i test diditlpoint forum on validator.w3.org i see only one error, so now i can say that there is a big relationship between higher html validation from validator.w3.org and higher pag rank what is your review of that??
After reading your post I checked the PR of one of my customer's websites I designed and compared it to one of my older sites. My customer's site is only about 4 months old with about 68 backlinks, and it's 100% W3C xhtml valid and CSS valid (fully coded in Web 2.0). The other site is about a year old with 142 backlinks, and has tons of validation errors. Both sites rank well for their terms, however to my amazement my customer's site has a PR of 4 while my older site has a PR of 3. Now there could be other factors influencing this such as the PR of the individual links, but it's still very interesting. Thanks for your post.
I find it amazing some people actually believe this. W3C Validation only, in theory, increases the cross-browser compatibility of a site. PageRank has no influence whatsoever on the site user, only on your ego.
Spider-man is absolutely right! Beeker, it could be just luck...... Backlinks and content are the main factors!
I don;t believe there's direct connection between PR and W3c W3C validation is only one from many factor to your PR
Here's something interesting from http://www.webpronews.com/insiderreports/2004/09/23/does-wc-validation-help-in-search-rankings: Any thoughts on this? Any sites I design now I make sure it's 100% valid xhtml and CSS for user compatibility as Spider-Man stated, but wouldn't validating also help with how easily Google and other engines can spider it?
If google say pagerank is determined by links and links alone http://www.google.com/support/webmasters/bin/answer.py?answer=49215&query=pagerank&topic=&type= http://www.google.com/technology/index.html I'm inclined to believe that it's determined by links and links alone.
On the example above then coding eras code influence serps - for instance, having a keyword in the title counts for jackshit if you have coded the site <h1 </h1> ... But as for PR - I thought that had everything to do with inbound links and not onpage factors...
I did some testing on this a while back and although validation can improve indexing it does nothing whatsoever with your PR.
i read google page for difenision of PR i see that: so what is the meanings of high quality sites??? 1-high qualit contents 2-high quality Votes from other sites(backlinks) 3- high quality design , even Css or html or what else i tested now a-digg b-en.wikipedia.org c-del.icio.us i always see that on w3.org and No errors so , open any internet page ,then get its source what is the first lines u see in the codes??? something like that so, is it only a luck??
Valid HTML makes no difference to the PR of your site, although it can help search engines trying to index it.
The reference to W3C is due to the fact the W3C (World Wide Web Consortium) publishes the standards of web development, as simple as that. Browsers then conform, or so they should, to the DTD as stated. The reason w3.org has no errors is simple - why would they? They lead the standards, why would they not pick up on coding errors? The point you are making is void - this is a doctype tag, and not a true backlink to that source. THIS is a truer account of why it has such high pagerank.
In theory Google could query w3.org and check for browser compatibility in the hope that ranking compatible sites higher will lower than rank of broken sites.
its very interesting but i must test this.. i heard that google's spiders are index the page easier if there is no coding errors and unnecessarry codes?
Well for your information Page Rank really depends on how many backlinks do you have and how popular is you site.
Gah, I want to +rep+ Spider-Man for telling you all the truth (despite nobody LISTENING), but I can't!
so, spider-man you refuse that but what we loose if our sites w3 valid?? lets try that ourselves , by our sites. i dont speak about why w3.org have PR=10 i only suggest that why every internet page ,have this code, in the first line i see , google boots read it in every page ,then know if that page is compatable with browsers or not then high PR or not that i see, i dont sure if that right or not
