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 HTML code and css code errors if written poorly or outdated does not really matter for actual seo and rankings on thier own.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 for multiple languages [Arabic]
Hello all, I am currently managing a Marketplace that comes in two different languages: English & Arabic. The English website is, fortunately, doing quite well in terms of SEO performances but, not the Arabic one. The website has two kinds of content: Static content: controlled by me. It includes menu items, navigation, static pages etc which is properly translated among the two languages User-uploaded content: It includes ads/news posted by the user which may not be translated to Arabic if they chose not to do it. Now if somebody goes to the Arabic website and check a news item that doesn't have an Arabic translation, it will show the English title. I am assuming, serving content in a different language that is specified in the hreflang is a straight no, right?

Would changing the file name of an image (not the alt attribute) have an effect of on seo / ranking of that image and thus the site?
Would changing the file name of image, not the alt attribute nor the image itself (so it would be exactly the same but just a name change) have any effect on : a) A sites seo ranking b) the individual images seo ranking (although i guess if b) would be true it would have an effect on a) although potentially small.) This is the sort of change i would be thinking of making :  changed to

Domain Forwarding - SEO Impacts?
I have a site that has been active for years - thinkbiglearnsmart.com. Awhile ago I had purchased about 50 domain names that were relevant to my company. I still have those urls and would like to use them to point to different pages on my site - just because they have good key words in the URLs. For example - one is dreamweavertrainingclassesonlinelive.com. Currently they are all redirecting to my homepage. A. is that hurting me? B. I would like to redirect to the more relevant page. ie the page dedicated to Dreamweaver training (http://thinkbiglearnsmart.com/dreamweaver-creative-cloud-training-course/ ) Will this hurt my Dreamweaver keyword for example because there is already a 301 redirect on that page from a very old Dreamweaver link which was something like thinkbiglearnsmart.com/dreamweaver C. On my hosting account where I can select where the URL forwards to - it has an option for "Location forwarding" and "Frame forwarding" - currently they are set to Frame forwarding - which one is best? Any help is much appreciated!!! Thank you!

How do 302 redirects from Akamai content targeting impact SEO?
How do 302 redirects from Akamai content targeting impact SEO? I'm using Akamai content targeting to get people from countries and languages to the right place (eg www.abc.123 to redirect to www.abc.123/NL-nl/default.aspx where folks from the Netherlands get their localized site in dutch) and from the edge server closest to them. As far as I know Akamai doesn't allow me to use anything but a 302. Anyone run across this? is this 302 a problem? I did a fetch as googlebot on my main domain and all I see is the Akamai 302. I can't imagine this is the first time Akamai has run across this but I would like to know for sure.

Does capitalization matter for SEO?
Two places capitalization comes into play: (1) on-page use (title, h1, body text, img alt text, etc) (2) external anchor text I didn't think it mattered from Google's point of view for on-page usage (is this correct?) but I notice that OpenSiteExplorer' s 'anchor text distribution' tab shows different counts for the same keyword if it's capitalized in different ways (eg seomoz.org is listed separate from SEOmoz.org). Is that just OSE or does Google treat the keyword/phrase different based on its capitalization, too? And if so, then should I be creating external links to my site with the 'regular' and 'Capitalized' versions of my key phrases?
