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 HTML code and css code errors if written poorly or outdated does not really matter for actual seo and rankings on thier own.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

Default Wordpress 301 Redirects of JS and CSS files. Bad for SEO & How to Fix?
Hi there: We are developers with some digital marketing expertise, but a current issue has us perplexed. An outside SEO firm has asked us to clean up a large number of 301 redirects. Most of these are 'default' Wordpress behavior that relate to calling the latest version of a JS or CSS file. For instance, a JS file is called with this: https://websitexyz.com/wp-includes/js/wp-embed.min.js?ver=4.9.1 but ultimately redirects to this: https://websitexyz.com/wp-includes/js/wp-embed.min.js. We are being asked to prevent the redirect from happening by, presumably, calling the ultimate file to begin with. The issue is that, as far as we know, there's no easy way to alter WP behavior to call the ultimate file to begin with. Does anyone have any thoughts on this? Thanks.

404's - Do they impact search ranking/how do we get rid of them?
Hi, We recently ran the Moz website crawl report and saw a number of 404 pages from our site come back. These were returned as "high priority" issues to fix. My question is, how do 404's impact search ranking? From what Google support tells me, 404's are "normal" and not a big deal to fix, but if they are "high priority" shouldn't we be doing something to remove them? Also, if I do want to remove the pages, how would I go about doing so? Is it enough to go into Webmaster tools and list it as a link no to crawl anymore or do we need to do work from the website development side as well? Here are a couple of examples that came back..these are articles that were previously posted but we decided to close out: http://loyalty360.org/loyalty-management/september-2011/let-me-guessyour-loyalty-program-isnt-working http://loyalty360.org/resources/article/mark-johnson-speaks-at-motivation-show Thanks!

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.

Migrating online store to subdomain using shopify and effects on seo and energy down the road for seo
I'm looking for some clarity... Looking at using Shopify for an existing online store that we have to migrate. Setting up the store with shopify means we will be using a subdomain such as shop.mywebsite.com instead of mywebsite.com/shop. The following are points to consider when responding The client currently has an online store, however it's a proprietary shopping store and CMS that has since gone defunct and they need to migrate to an alternative in order to survive online against new CMS systems that allow the site and its content to be better optimized. There is a lot of existing SEO done on the current site that we don't want to loose PR on. There is roughly 2000 products Client has a fixed budget, dealing with checkout issues, custom work and various other "bugs" seems to be easier controlled with Shopify...thus budget can be used more on content/strategy and migration We want to run the main site in Wordpress and are wanting to use Shopify since it supports a gateway, has great features and seems like it would allow us to get more bang for the buck and can focus more on the main site and content strategy and drive traffic to the subdomain store if needed Or main concern is the effort of migrating 2000+ products to shopify and the traffic and PR it gives the current site will have a negative effect on the main domain itself. Should we really be considering this path? The domain is diveidc.com One main benefit to the subdomain is the ability to clearly segment products from the service portion of the site in the analytics and focus 2 clear strategies and track it in a very defined manner. We're really on the fence with this...any thoughts are welcome.

301 redirect from .html to non .html?
Previously our site was using this as our URL structure: www.site.com/page.html. A few months ago we updated our URL structure to this: www.site.com/page & we're not using the .html. I've read over this guide & don't see anywhere that discusses this: http://www.seomoz.org/learn-seo/redirection. I've currently got a programmer looking into, but am always a bit weary with their workarounds, as I'd previously had them cause more problems then fix it. Here is the solution he is looking to do: The way that I am doing the redirect is fine. The problem is of where to put the code. The issue is that the files are .html files that need to be redirected to the same url with out a .html on them. I can see if I can add that to the 404 redirect page if there is one inside of there and see if that does the trick. That way if there is no page that exists without the .html then it will still be a 404 page. However if it is there then it will work as normal. I will see what I can find and get back. Any help would be greatly appreciated. Thanks, BJ

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?
