There have been theories on Seo Blogs and forums that Google ranks higher Well-formed, Validated pages with no syntax errors.
The actually policy is revealed here:
At a search engine, you have to write your code to process all that randomness and return the best documents. By the way, that’s why we don’t penalize sites if they have syntax errors or don’t validate — sometimes the best document isn’t well-formed or has a syntax error.http://www.mattcutts.com/blog/the-web-is-a-fuzz-test-patch-your-browser-and-your-web-server/

You gotta wonder, when Matt misses things that should be obvious to anyone working with web documents. He writes:

> a filetype of exe
If you look at the search results Matt links to, you'll see that these are not "exe files put up on the web". They are simply compiled CGIs which take a query parameter to generate the HTML page.
For example, you could have a CGI that looks like this:
example.com/index.php?document=219
or you could have a CGI that looks like this:
example.com/index.exe?document=219
Neither of these is more well-formed or inherently more secure. CGI can be implemented by any interpreted script or compiled executable. Heck, my webhost even lets you write your web applications using their FORTRAN compiler! |
A syntax error can introduce ambuigity which will then even result in ranking differences.
Let's assume the hypothetical case in which you leave a tag open:
<p><a href="...">like this</p>
Now, maybe the browser you happen to test this with will assume "when the </p> appears, probably the link should be closed". So you won't notice it immediately. However, the search engine crawler may resolve this "ambuigity" differently and dedide the rest of the page is actually a giant link... and then reacting with random other stuff (e.g. deciding it's keyword stuffing, as so many keywords are in the link).
This was just a random example (pls ignore its specifics!) but I hope it gets the general idea across that yes, invalid documents CAN affect even search engines. |

HAS GOOGLE BEGUN PENALIZING DIRECTORIES NOW?????
there is another interesting post on that blog that references this article
http://sphinn.com/story/4415
If this is true – that directories have been penalized the way blogs and sites selling links without the NOFOLLOW have......
FORGET IT FRIENDS!!!!!
there will be NO other way for a small biz to competitively optimize...
So cave in, and forever by ADWORDS – which is what is behind all of this so-called SERPs cleansing. |
