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 HTML code and css code errors if written poorly or outdated does not really matter for actual seo and rankings on thier own.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.
Free page speed test with results breakdown can be had there => http://www.webpagetest.org
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.

SEO impact of 301 redirects based on IP addresses from a specific state
Hello Moz Community! We are facing an issue that may or may not be unique, but need some advice and/or clarification on the best way to address the issue. We recently rebranded and launched a new site under a new domain and things have been progressing well. However, despite all the up front legwork on trademarks and licensing, we have recently encountered a hiccup that forces us to revert to the old URL/branding for one specific state. This may be a temporary issue that lasts a couple of months or it could potentially be in the court system for a couple of years. One potential solution we have discussed is to redirect the new site to the old site based on IP addresses for the state in question. Looking for any guidance on what type of impact this may have on SEO. Also open to any other suggestions or guidance on dealing with this situation. Thanks

CDN for SEO (or not)?
Does CDN impact on SEO or not? There seems conflicting ideas as to whether they impact positively or negatively, I realise that if the page loads quicker this is a good thing for SEO and usability of course. Does Google see CDN as just cheating and a get-around for not doing the work from the ground up and using good hosting etc? Do you have any direct experience? All constructive input much appreciated!

Would you rate-control Googlebot? How much crawling is too much crawling?
One of our sites is very large - over 500M pages. Google has indexed 1/8th of the site - and they tend to crawl between 800k and 1M pages per day. A few times a year, Google will significantly increase their crawl rate - overnight hitting 2M pages per day or more. This creates big problems for us, because at 1M pages per day Google is consuming 70% of our API capacity, and the API overall is at 90% capacity. At 2M pages per day, 20% of our page requests are 500 errors. I've lobbied for an investment / overhaul of the API configuration to allow for more Google bandwidth without compromising user experience. My tech team counters that it's a wasted investment - as Google will crawl to our capacity whatever that capacity is. Questions to Enterprise SEOs: *Is there any validity to the tech team's claim? I thought Google's crawl rate was based on a combination of PageRank and the frequency of page updates. This indicates there is some upper limit - which we perhaps haven't reached - but which would stabilize once reached. *We've asked Google to rate-limit our crawl rate in the past. Is that harmful? I've always looked at a robust crawl rate as a good problem to have. Is 1.5M Googlebot API calls a day desirable, or something any reasonable Enterprise SEO would seek to throttle back? *What about setting a longer refresh rate in the sitemaps? Would that reduce the daily crawl demand? We could set increase it to a month, but at 500M pages Google could still have a ball at the 2M pages/day rate. Thanks

/%category%/%postname%/ Permalink structure
Mostly everyone seems to agree that /%category%/%postname%/ is the best blog structure. I'm thinking of changing my structure to that because now it's structured by date which is bad. But almost all of my posts are assigned to more than one category. Won't this create duplicate pages?
