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

Link rel="prev" AND canonical
Hi guys, When you have several tabs on your website with products, you can most likely navigate to page 2, 3, 4 etc...
Technical SEO | | AdenaSEO
You can add the link rel="prev" and link rel="next" tags to make sure that 1 page get's indexed / ranked by Google. am I correct? However this still means that all the pages can get indexed, right? For example a webshop makes use of the link rel="prev" and ="next" tags. In the Google results page though, all the seperate tabs pages are still visible/indexed..
http://www.domain.nl/watches/?tab=1
http://www.domain.nl/watches/?tab=24
http://www.domain.nl/watches/?tab=19
etc..... Can we prevent this, and make sure only the main page get's indexed and ranked, by adding a canonical link on every 'tab page' to the main page --> www.domain.nl/watches/ I hope I explained it well and I'm looking forward to hearing from you. Regards, Tom1 -
What is the difference between "Referring Pages" and "Total Backlinks" [on Ahrefs]?
I always thought they were essentially the same thing myself but appears there may be a difference? Any one care to help me out? Cheers!

"Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?
Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

Use webmaster tools "change of address" when doing rel=canonical
We are doing a "soft migration" of a website. (Actually it is a merger of two websites). We are doing cross site rel=canonical tags instead of 301's for the first 60-90 days. These have been done on a page by page basis for an entire site. Google states that a "change of address" should be done in webmaster tools for a site migration with 301's. Should this also be done when we are doing this soft move?

How is a dash or "-" handled by Google search?
I am targeting the keyword AK-47 and it the variants in search (AK47, AK-47, AK 47) . How should I handle on page SEO? Right now I have AK47 and AK-47 incorporated. So my questions is really do I need to account for the space or is Google handling a dash as a space? At a quick glance of the top 10 it seems the dash is handled as a space, but I just wanted to get a conformation from people much smarter then I at seomoz. Thanks, Jason

Google is Showing Website as "Untitled"
My freelance designer made some changes to my website and all of a sudden my homepage was showing the title I have in Dmoz. We thought maybe the NOODP tag was not correct, so we edited that a little and now the site is showing as "Untitled". The website is http://www.chemistrystore.com/. Of course he didn't save an old copy that we can revert to. That is a practice that will end. I have no idea why the title and description that we have set for the homepage is not showing in google when it previously was. Another weird thing that I noticed is that when I do ( site:chemistrystore.com ) in Google I get the https version of the site showing with the correct title and description. When I do ( site:www.chemistrystore.com ) in Google I don't have the hompage showing up from what I can tell, but there are 4,000+ pages to the site. My guess is that if it is showing up, it is showing up as "Untitled". My question is.... How can we get Google to start displaying the proper title and description again?

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.
