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 HTML code and css code errors if written poorly or outdated does not really matter for actual seo and rankings on thier own.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.

What does Disallow: /french-wines/?* actually do - robots.txt
Hello Mozzers - Just wondering what this robots.txt instruction means: Disallow: /french-wines/?* Does it stop Googlebot crawling and indexing URLs in that "French Wines" folder - specifically the URLs that include a question mark? Would it stop the crawling of deeper folders - e.g. /french-wines/rhone-region/ that include a question mark in their URL? I think this has been done to block URLs containing query strings. Thanks, Luke

Does collapsing content impact Google SEO signals?
Recently I have been promoting custom long form content development for major brand clients. For UX reasons we collapse the content so only 2-3 sentences of the first paragraph are visible. However there is a "read more" link that expands the entire content piece.

I have believed that the searchbots would have no problem crawling, indexing and applying a positive SEO signal for this content. However I'm starting to wonder. Is there any evidence that the Google search algorithm could possible discount or even ignore collapsed content?1 -
Display:None CSS & SEO
Hi A while back I was told that using the display:none tag to hide content you want minimised is bad for onpage SEO - is this the case? It's not that we want to hide it from Google, we just don't want it taking up a huge amount of space on product pages. I have found some of these on our site, and want to know how bad they are. Is the content under the tag going to be ignored? Thank you

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!

Followup question to rand(om) question: Would two different versions (mobile/desktop) on the same URL work well from an SEO perspective and provide a better overall end-user experience?
We read today's rand(om) question on responsive design. This is a topic we have been thinking about and ultimately landing on a different solution. Our opinion is the best user experience is two version (desktop and mobile) that live on one URL. For example, a non-mobile visitor that visits http://www.tripadvisor.com/ will see the desktop (non-responsive) version. However, if a mobile visitor (i.e. iOS) visits the same URL they will see a mobile version of the site, but it is still on the same URL There is not a separate subdomain or URL - instead the page dynamically changes based on the end user's user agent. It looks like they are accomplishing this by using javascript to change the physical layout of the page to match the user's device. This is what we are considering doing for our site. It seems this would simultaneously solve the problems mentioned in the rand(om) question and provide an even better user experience. By using this method, we can create a truly mobile version of the website that is similar to an app. Unfortunately, mobile versions and desktop users have very different expectations and behaviors while interacting with a webpage. I'm interested to hear the negative side of developing two versions of the site and using javascript to serve the "right" version on the same URL. Thanks for your time!

A very basic seo question
Sorry, been a long day and wanted a second opinion on this please.... I am developing an affiliate store which will have dozens of products in each category. We will not be indexing the product pages themselves as they are all duplicate content. The plan is to have just the first page of the category results indexed as this will have unique content about the products in that section. The later pagnated pages (ie pages 2,3,4,5 etc) will have 12 products on each but no unique content. Would the best advice be to add a canonical tag to all pages in the 'chairs' category pointing to the page with the first 12 results and the descriptions? This would ensure that the visitors are able to browse many pages of product but google won't index products 13 and onwards. Am I right in my thinkings? A supplemental question. What is the best way to block google from indexing/crawling 90,000 product listings which are pulled direct from the merchant so are not unique in the least. I have previous played with banning google from the product folder but it reports health issues in webmaster tools. Would the best route be a no index tag on all the product pages and to no follow all the products in the category listings? Many thanks Carl
