Duplicate Content - Mobile Site
-
We think that a mobile version of our site is causing a duplicate content issue; what's the best way to stop the mobile version being indexed. Basically the site forwards mobile users to "/mobile" which is just a mobile optimised version of the original site.
Is it best to block the /mobile folder from being crawled?
-
If you want to block the /mobile folder from being crawled you would need to set up a robots.txt file and input this text:
User-agent: *
Disallow: /mobile
Personally, I would use the rel=canonical tag and tell search engines that the preferred version of the page would be the non-mobile version. You can learn more about rel=canonical here...

Duplicate content or an update ???
Buying Guide and Product Category page competing for the same keyword ? Got a “nuts and bold website” selling basic stuff. Imagine selling simple nuts, bolts and washers (the little ring that goes in between) in different metals. Imagine a website with a very wide and deep line of these simple products. For long tail keywords we rank well (Example: 0.25 inch bolts). For the keyword: “Nuts bolts” our main category page use to rank well low 1<sup>st</sup> page to second page up against the big guys (Amazon, Walmart, Target, Costco, some drug store who may have a mix pack of nuts and bolts, but still Google don’t see the difference and list 2 pages each for these guys). But then in mid-February there were an update and suddenly our “Buying guide for nuts and bolts” rank higher and started to compete with our own product category page. That was never our intention. These two pages now compete for the ranking on page 4<sup>th</sup>. Clearly there were more words on the buying guide page but no changes had been made to it for well months or years. To make up for it some more words were added to the category page, but of cause there is only so many way you can fraise words about “nuts and bolts” without sounding a bit duplicate/re-writing. So what do I do now ?? Clearly the product category page is the one we like to rank highest with the guide a close 2nd. Most customer don’t need the buying guide but it is good to have and great support as we got lot of good comments from customer who read it. Made a link to the buying guide from the category page and wise verses. The category page got an embedded video. Moz list the page authority for the category page to 16 and 1 for the buying guide but clearly G see it differently. Already tried to change the Meta Tag Title and Description a little but it is hard to do if the word “Nuts Bolts” is to appear in the description or people don’t know what to expect. Could just insert a “do not index” for the buying guide but not a good long term solution. Unfortunately I am out of imagination at this point. Any good suggestions ?? Thanks, Kim Any good suggestions ???

Duplicate Content Mystery
Hi Moz community! I have an ongoing duplicate mystery going on here and I'm hoping someone here can answer my question. We have an Ecommerce site that has a variety of product pages and category pages. There are Rel canonicals in place, along with parameters in GWT, and there are also URL rewrites. Here are some scenarios, maybe you can give insight as to what’s exactly going on and how to fix it. All the duplicates look to be coming from category pages specifically. For example:
Technical SEO | | Ecom-Team-Access
This link re-writes: http://www.incipio.com/cases/tablet-cases/amazon-kindle-cases-sleeves.html?cat=407&color=152&price=20- To: http://www.incipio.com/cases/tablet-cases/amazon-kindle-cases-sleeves.html The rel canonical tag looks like this: http://www.incipio.com/cases/tablet-cases/amazon-kindle-cases-sleeves.html" /> The CONTENT is different, but the URLs are the same. It thinks that the product category view is the same as the all products view, even though there is a canonical in there telling it which one is the original. Some of them don’t have anything to do with each other. Take a look: Link identified as duplicate: http://www.incipio.com/cases/smartphone-cases/htc-smartphone-cases/htc-windows-phone-8x-cases.html?color=27&price=20- Link this is a duplicate of: http://www.incipio.com/cases/macbook-cases/macbook-pro-13in-cases.html Any idea as to what could be happening here?0 -
Tired of finding solution for duplicate contents.
Just my site was scanned by seomoz and seen lots of duplicate content and titles found. Well I am tired of finding solutions of duplicate content for a shopping site product category page. You can see the screenshot below. http://i.imgur.com/TXPretv.png You can see below in every link its showing "items_per_page=64, 128 etc.". This happened in every category in which I was created. I am already using Canonical add-on to avoid this problem but still it's there. You can check my domain here - http://www.plugnbuy.com/computer-software/pc-security/antivirus-internet-security/ and see if the add-on working correct. I recently submitted my sitemap to GWT, so that's why it's not showing me any report regarding duplicate issues. Please help ME

Duplicate video content question
This is really two questions in one. 1. If we put a video on YouTube and on our site via Wistia, how would that affect our rankings/authority/credibility? Would we get punished for duplicate video content? 2. If we put a Wistia hosted video on our website twice, on two different pages, we would get hit for having duplicate content? Any other suggestions regarding hosting on Wistia and YouTube versus just Wistia for product videos would be much appreciated. Thank you!

Fix duplicate content caused by tags
Hi everyone, TGIF. We are getting hundreds of duplicate content errors on our WP site by what appears to be our tags. For each tag and each post we are seeing a duplicate content error. I thought I had this fixed but apparently I do not. We are using the Genesis theme with Yoast's SEO plugin. Does anyone have the solution to what I imagine is this easy fix? Thanks in advance.

Bad Duplicate content issue
Hi, for grappa.com I have about 2700 warnings of duplicate page content. My CMS generates long url like: http://www.grappa.com/deu/news.php/categoria=latest_news/idsottocat=5 and http://www.grappa.com/deu/news.php/categoria%3Dlatest_news/idsottocat%3D5 (this is a duplicated content). What's the best solution to fix this problem? Do I have to set up a 301 redirect for all the duplicated pages or insert the rel=canonical or rel=prev,next ? It's complicated becouse it's a multilingual site, and it's my first time dealing with this stuff. Thanks in advance.
