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

"Noindex, follow" for thin pages?
Hey there Mozzers, I have a question regarding Thin pages. Unfortunately, we have Thin pages, almost empty to be honest. I have the idea to ask the dev team to do "noindex, follow" on these pages. What do you think? Has someone faced this situation before? Will appreciate your input!

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?

Where did the "Location" go, on Google SERP?
In order to emulate different locations, I've always done a Google query, then used the "Location" button under "Search Tools" at the top of the SERP to define my preferred location. It seems to have disappeared in the past few days? Anyone know where it went, or if it's gone forever? Thanks!

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 -

404 crawl errors from "tel:" link?
I am seeing thousands of 404 errors. Each of the urls is like this: abc.com/abc123/tel:1231231234 Everything is normal about that url except the "/tel:1231231234" these urls are bad with the tel: extension, they are good without it. The only place I can find this character string is on each page we have this code which is used for Iphones and such. What are we doing wrong? Code: Phone: <a href="[tel:1231231234](tel:7858411943)"> (123) 123-1234a>

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

301 Redirect "wildcard" question
I have been looking at the SEOmoz redirect guide for some advice but I can't seem to find the answer : http://www.seomoz.org/learn-seo/redirection I have lots of URLs from a previous version of a site that look like the following: sitename.com/-c-25.html?sort=2d&page=1 sitename.com/-c-25.html?sort=3a&page=1 etc etc. I want to write a redirect so whenever a URL with the terms "-c-25.html" is requested it redirects to a specified page, regardless of what comes after the question mark. These URLs were created by our previous ecommerce software. The 'c' is for category, and each page of the cateogry created a different URL. I want to do these so I can rediect all of these URLs to the appropraite new cateogry page in a single redirect. Thanks for any help.
