Magento Dublicate Content (Noindex and Rel"canonical")
-
Hi All,
Just looking for some advice regarding my website on magento.
We by mistake didnt enable canonical tags and noindex tags so had a big problem with dublicate content from filter pages but also have URLs to Cats as Yes so this didnt help with not having canonical tags enabled.
We now have everything enabled for a few weeks now but dont see much drop in indexed pages in google. (currently 27k and we have only 5k products)
My question basically is how do we speed up noindexation of dublicate content and also would you change URL to cats as No so google just now sees the url to products? (my concerns with this is would leaving it to Yes help because it will hopefully read the canonical tags on products now)
Thank you in advance
Michael

Hi Carson
Thank you for replying and the indepth answers.
I did read somewhere that dublicate content on your own website isnt too bad but im glad you have helped me clear things up.
So would you change cat urls to no or leave them to yes for now till google can see all the canoical tags on products?
Thanks
Mike

I think there's an underlying assumption here that duplicate content will harm your site, and that's not necessarily true. There's no "duplicate content penalty" - it's more than a filter. Google is better than most at recognizing this, especially with common CMS like Magento and WP. Google attempts to look at the links going to both pages and understand their authority together.
Duplicate content is more of an issue if you're pulling content that others are using as well, e.g. on product descriptions provided by manufacturers and other types of content. Google won't "penalize" you, but they will sometimes filter your site out in favor of the most authoritative site with that content. It's also an issue (mostly for Panda) if you're creating keyword pages that contain duplicate of even very-similar content just to rank for a bunch of very similar keywords.
So my first bit of advice is, "don't obsess over intra-site duplicate content."
That said, it's best to reduce and avoid duplicate content 1) for less-sophisticated search engine, 2) for the sake of your own analytics data integrity and simplicity, 3) just in case Google doesn't get it (very rare).
Set the categories up however you think is best for the user (generally just the product name without categories), double-check the canonical URLs, and wait for Google to catch up on the canonical and noindex. It can take many months depending on your site's authority, but it's unlikely to move the needle either way. Keep in mind that Google may keep pages in the index even if they are honoring the canonical tag - they'll just show the canonical version but keep both indexed. That's working as intended - don't worry about that

Rel=canonical on Godaddy Website builder
Hey crew! First off this is a last resort asking this question here. Godaddy has not been able to help so I need my Moz Fam on this one. So common problem My crawl report is showing I have duplicate home pages www.answer2cancer.org and www.answer2cancer.org/home.html I understand this is a common issue with apache webservers which is why the wonderful rel=canonical tag was created! I don't want to go through the hassle of a 301 redirect of course for such a  simple issue. Now here's the issue. Godaddy website builder does not make any sense to me. In wordpress I could just go add the tag to the head in the back end. But no such thing exist in godaddy. You have to do this weird drag and drop html block and drag it somewhere on the site and plug in the code. I think putting before the code instead of just putting it in there. So I did that but when I publish and inspect in chrome I cannot see the tag in the head! This is confusing I know. the guy at godaddy didn't stand a chance lol. Anyway much love for any replies!

How do I "undo" or remove a Google Search Console change of address?
I have a client that set a change of address in Google Search Console where they informed Google that their preferred domain was a subdomain, and now they want Google to also consider their base domain (without the change of address). How do I get the change of address in Google search console removed?

Rel=Canonical, WWW vs non WWW and SEO
Okay so I'm a bit of a loss here. For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar. I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise? Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same? Or am I wrong and all that link juice and authority passes just the same?

Rel="external"
Hi all, I got a link and its off a site and marked up with rel="external". Is this a followed or nofollowed link? Does it pass link juice? Thanks

Why "title missing or empty" when title tag exists?
Greetings! On Dec 1, 2011 in a SEOMoz campaign, two crawl metrics shot up from zero (Nov 17, Nov 24). "Title missing or empty" was 9,676. "Duplicate page content" was 9,678. Whoa! Content at site has not changed. I checked a sample of web pages and each seems to have a proper TITLE tag. Page content differs as well -- albeit we list electronic part numbers of hard-to-find parts, which look similar. I found a similar post http://www.seomoz.org/q/why-crawl-error-title-missing-or-empty-when-there-is-already-title-and-meta-desciption-in-place . In answer, Sha ran Screaming Frog crawler. I ran Frog crawler on a few hundred pages.  Titles were found and hash codes were unique. Hmmm. Site with errors is http://electronics1.usbid.com Small sample of pages with errors: electronics1.usbid.com/catalog_10.html

Why crawl error "title missing or empty" when there is already "title and meta desciption" in place?
I've been getting 73 "title missing or empty" warnings from SEOMOZ crawl diagnostic. This is weird as I've installed yoast wordpress seo plugin and all posts do have title and meta description. But why the results here.. can anyone explain what's happening? Thanks!! Here are some of the links that are listed with "title missing, empty". Almost all our blog posts were listed there. http://www.gan4hire.com/blog/2011/are-you-here-for-good/ http://www.gan4hire.com/blog/2011/are-you-socially-awkward/

What is best practice for redirecting "secondary" domain names?
For sites with multiple top-level domains that have been secured for a business or organization, I'm curious as to what is considered best practice for setting up 301 redirects for secondary domains. Is it best to do the 301 redirects at the registrar level, or the hosting level? So that .net, .biz, or other secondary domains funnel visitors to the correct primary/main domain name. I'm looking for the "best practice" answer and want to avoid duplicate content problems, or penalties from the search engines. I'm not trying to game the system with dozens of domain names, simply the handful of domains that are important to the client. I've seen some registrars recommend hosting secondary domains, and doing redirects from the hosting level (and they use meta refresh for "domain forwarding," which I want to avoid). It seems rather wasteful to set up hosting for a secondary domain and then 301 each URL.
