How much does dirty html/css etc impact SEO?
-
Good Morning!
I have been trying to clean up this website and half the time I can't even edit our content without breaking the WYSIWYG Editor. Which leads me to the next question. How much, if at all, is this impacting our SEO. To my knowledge this isn't directly causing any broken pages for the viewer, but still, it certainly concerns me.
I found this post on Moz from last year:
http://moz.com/community/q/how-much-impact-does-bad-html-coding-really-have-on-seo
We have a slightly different set of code problems but still wanted to revisit this question and see if anything has changed.
I also can't imagine that all this broken/extra code is helping our page load properly.
Thanks everybody!

Invalid code does not equate to slow code. Google used to purposely not close html and body tags to save bandwidth and loading time. I took the question as meaning w3c valid code.

Bad code can definately affect seo rankings for a website.
The question really depends on what exactly is wrong with the code. If its causing problems with page load speed times, that could be a problem for sure. HTML code and css code errors if written poorly or outdated does not really matter for actual seo and rankings on thier own. Unless these erros are causing other issues such as user experience which would increase bounce rates and affect rankings. If the code errors are causing duplicate pages., Html errors like missing H1, tags and such can affect on page seo scores which affect rankings. So in my honest opinion bad code can definately affect seo rankings for a website.

Definately clean up all the HTML seo factors, usuability issues and page speed issues. Hope that helps, Have a great day, Joe

As long as links are not broken and resources are not returning 404 errors, my understanding is that it is not affected at all. The only thing I would make sure of is that fetch as google returns the page looking like it should. Here is a video from the authority on the matter.

Javascript and SEO
I've done a bit of reading and I'm having difficulty grasping it. Can someone explain it to me in simple language? What I've gotten so far: Javascript can block search engine bots from fully rendering your website. If bots are unable to render your website, it may not be able to see important content and discount these content from their index. To know if bots could render your site, check the following: Google Search Console Fetch and Render Turn off Javascript on your browser and see if there are any site elements shown or did some disappear Use an online tool Technical SEO Fetch and Render Screaming Frog's Rendered Page GTMetrix results: if it has a Defer parsing of Javascript as a recommendation, that means there are elements being blocked from rendering (???) Using our own site as an example, I ran our site through all the tests listed above. Results: Google Search Console: Rendered only the header image and text. Anything below wasn't rendered. The resources googlebot couldn't reach include Google Ad Services, Facebook, Twitter, Our Call Tracker and Sumo. All "Low" or blank severity. Turn off Javascript: Shows only the logo and navigation menu. Anything below didn't render/appear. Technical SEO Fetch and Render: Our page rendered fully on Googlebot and Googlebot Mobile. Screaming Frog: The Rendered Page tab is blank. It says 'No Data'. GTMetrix Results: Defer parsing of JavaScript was recommended. From all these results and across all the tools I used, how do I know what needs fixing? Some tests didn't render our site fully while some did. With varying results, I'm not sure where to from here.

How does Googlebot evaluate performance/page speed on Isomorphic/Single Page Applications?
I'm curious how Google evaluates pagespeed for SPAs. Initial payloads are inherently large (resulting in 5+ second load times), but subsequent requests are lightning fast, as these requests are handled by JS fetching data from the backend. Does Google evaluate pages on a URL-by-URL basis, looking at the initial payload (and "slow"-ish load time) for each? Or do they load the initial JS+HTML and then continue to crawl from there? Another way of putting it: is Googlebot essentially "refreshing" for each page and therefore associating each URL with a higher load time? Or will pages that are crawled after the initial payload benefit from the speedier load time? Any insight (or speculation) would be much appreciated.

How does badly formatted HTML affect SEO?
Our website uses a custom built CMS, but uses a fairly standard WYSIWYG text editor. I've looked at some of the code it produces, and it's not pretty. My gut feeling tells me that this extra bloat is bad for SEO. Am I right in thinking that Google doesn't look kindly upon badly formatted and bloated HTML? Thanks,

Duplicate Content http://www.website.com and http://website.com
I'm getting duplicate content warnings for my site because the same pages are getting crawled twice? Once with http://www.website.com and once with http://website.com. I'm assuming this is a .htaccess problem so I'll post what mine looks like. I think installing WordPress in the root domain changed some of the settings I had before. My main site is primarily in HTML with a blog at http://www.website.com/blog/post-name BEGIN WordPress <ifmodule mod_rewrite.c="">RewriteEngine On
