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://azwa.1clkaccess.in/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 HTML code and css code errors if written poorly or outdated does not really matter for actual seo and rankings on thier own.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.

Ogranization Schema/Microformat for a content/brand website | Travel
Hi, One of our clients have a website specific to a place, for eg. California Tourism in which they publish local information related to tourism, blogs & other useful content. I want to understand how useful is to publish Organization Schema on such website mentioning the actual Organization, which in this case is a Travel Agency? Or any other schema would fit in for such websites?

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.

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

SEO Impact of High Volume Vertical and Horizontal Internal Linking
Hello Everyone - I maintain a site with over a million distinct pages of content. Each piece of content can be thought of like a node in graph database or an entity. While there is a bit of natural hierarchy, every single entity can be related to one or more other entities. The conceptual structure of the entities like so: Agency - A top level business unit ( ~100 pages/urls) Office - A lower level business unit, part of an Agency ( ~5,000 pages/urls) Person - Someone who works in one or more Offices ( ~80,000 pages/urls) Project - A thing one or more People is managing ( ~750,000 pages/urls) Vendor - A company that is working on one or more Projects ( ~250,000 pages/urls) Category - A descriptive entity, defining one or more Projects ( ~1,000 pages/urls) Each of these six entities has a unique (url) and content. For each page/url, there are internal links to each of the related entity pages. For example, if a user is looking at a Project page/url, there will be an internal link to one or more Agencies, Offices, People, Vendors, and Categories. Also, a Project will have links to similar Projects. This same theory holds true for all other entities as well. People pages link to their related Agencies, Offices, Projects, Vendors, etc, etc. If you start to do the math, there are tons of internal links leading to pages with tons of internal links leading to pages with tons of internal links. While our users enjoy the ability to navigate this world according to these relationships, I am curious if we should force a more strict hierarchy for SEO purposes. Essentially, does it make sense to "nofollow" all of the horizontal internal links for a given entity page/url? For search engine indexing purposes, we have legit sitemaps that give a simple vertical hierarchy...but I am curious if all of this internal linking should be hidden via nofollow...? Thanks in advance!

SEO impact difference between a URL Rewrite and 301 redirect
Hi guys and girls! Just putting a new site live, we changed the URL from one thing to another and I created a 301 file redirecting the urls like for like. The developer installing it has created a different file with columns like: RewriteRule ^page/ http://www.site/page [R=301,L] RewriteRule ^/page/ http://www.site/page [R=301,L] What's the difference? The page redirects but is there a difference between the 301 redirect and this URL rewrite in terms of SEO and link value?

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!
