Solve duplicate content issues by using robots.txt
-
Hi,
I have a primary website and beside that I also have some secondary websites with have same contents with primary website. This lead to duplicate content errors. Because of having many URL duplicate contents, so I want to use the robots.txt file to prevent google index the secondary websites to fix the duplicate content issue. Is it ok?
Thank for any help!
-
yes, robots.txt is the bad way, I will try to use canonical tag. Thanks for your help!

Using robots.txt is perhaps not the best way of doing it. Using the canonical or a noindex meta tag would likely be best. I think the reasons for this are best summed up in this article which explains, probably better than I could, why robots.txt is not the best way of dealing with duplicate content. Hope this helps.

I have tried to use cross-domain canonical, but this is too difficult for me. So, I want to confirm if I use the robots.txt file is ok or not?
Thanks

Why not use a cross-domain canonical whereby you reference the pages on your primary website as the canonical version on your secondary websites, thereby eliminating the duplication.
For example on each page that is duplicate on your secondary website you would add the following to the head to reference the primary pages:

Does using Yoast variables for meta content overwrite any pages that already have custom meta content?
The question is about the Yoast plugin for WP sites. Let's say I have a site with 200 pages and custom meta descriptions / title tags already in place for the top 30 pages. If I use the Yoast variable tool to complete meta content for the remaining pages (and make my Moz issue tracker look happier), will that only affect the pages without custom meta descriptions or will it overwrite even the pages with the custom meta content that I want? In this situation, I do want to keep the meta content that is already in place on select pages. Thanks! Zack

Should I use an acronym in my URL?
I know that Google understands various acronyms. Example: If I search for CRM System, it knows i'm searching for a customer relationship management system. However, will it recognize less known acronyms? I have a page geared specifically for SAP data archiving for human capital management systems. For those in the industry, they simply call it HCM. Here is how I view my options: Option #1: www.mywebsite.com/sap-data-archiving/human-capital-management Option #2: www.mywebsite.com/sap-data-archiving/hcm Option #3: www.mywebsite.com/sap-data-archiving/hcm-human-capital-management With option #3, i'm capturing the acronym AND the full phrase. This doesn't make my URL overly long either. Of course, in my content i'll reference both. What does everyone else think about the URL? -Alex

Duplicate page titles and Content in Woocommerce
Hi Guys, I'm new to Moz and really liking it so far!
On-Page Optimization | | jeeyer
I run a eCommerce site on Wordpress + WooCommerce and ofcourse use Yoast for SEO optimalisation I've got a question about my first Crawl report which showed over 600 issues! 😐 I've read that this is something that happens more often (http://a-moz.groupbuyseo.org/blog/setup-wordpress-for-seo-success). Most of them are categorized under:
1. Duplicate Page Titles or;
2. Duplicate Page Content. Duplicate Page Titles:
These are almost only: product category pages and product tags. Is this problem beeing solved by giving them the right SEO SERP? I see that a lot of categories don't have a proper SEO SERP set up in yoast! Do I need to add this to clear this issue, or do I need to change the actual Title? And how about the Product tags? Another point (bit more off-topic) I've read here: http://a-moz.groupbuyseo.org/community/q/yoast-seo-plugin-to-index-or-not-to-index-categories that it's advised to noindex/follow Categories and Tags but isn't that a wierd idea to do for a eCommerce site?! Duplicate Page Content:
Same goes here almost only Product Categories and product tags that are displayed as duplicate Page content! When I check the results I can click on a blue button for example "+ 17 duplicates" and that shows me (in this case 17 URLS) but they are not related to the fist in any way so not sure where to start here? Thanks for taking the time to help out!

Sliders and Content Above the Fold
I was just inspecting a wire frame that is going out to a client and realized that the slider may interfere with the "content above the fold." Can't believe this had not struck me on others. If the Header has basic business info, etc. in it and you place a slider to display images in the area just beneath the Header or slightly down from it, does that decrease the amount of content seen a being above the fold? Or, is content above the fold established by virtue of H1,2, 3, etc.?

How do we handle sitemaps in robots.txt when multiple domains point to same physical location?
we have www.mysite.net, www.mysite.se, www.mysite.fi and so on. all of these domains point to the same physical location on our webserver, and we replace texts given back to client depending on which domain he/she requested. My problem is this: How do i configure sitemaps in robots.txt when robots.txt is used by multiple domains? If I for instance put the rows Sitemap: http://www.mysite.net/sitemapNet.xml

Sitemap: http://www.mysite.net/sitemapSe.xml in robots.txt, would that result in some cross submission error?0 -
Percentage of duplicate content allowable
Can you have ANY duplicate content on a page or will the page get penalized by Google? For example if you used a paragraph of Wikipedia content for a definition/description of a medical term, but wrapped it in unique content is that OK or will that land you in the Google / Panda doghouse? If some level of duplicate content is allowable, is there a general rule of thumb ratio unique-to-duplicate content? thanks!

Would it be bad to change the canonical URL to the most recent page that has duplicate content, or should we just 301 redirect to the new page?
Is it bad to change the canonical URL in the tag, meaning does it lose it's stats? If we add a new page that may have duplicate content, but we want that page to be indexed over the older pages, should we just change the canonical page or redirect from the original canonical page? Thanks so much! -Amy

Avoiding "Duplicate Page Title" and "Duplicate Page Content" - Best Practices?
We have a website with a searchable database of recipes. You can search the database using an online form with dropdown options for: Course (starter, main, salad, etc)
On-Page Optimization | | smaavie
Cooking Method (fry, bake, boil, steam, etc)
Preparation Time (Under 30 min, 30min to 1 hour, Over 1 hour) Here are some examples of how URLs may look when searching for a recipe: find-a-recipe.php?course=starter
find-a-recipe.php?course=main&preperation-time=30min+to+1+hour
find-a-recipe.php?cooking-method=fry&preperation-time=over+1+hour There is also pagination of search results, so the URL could also have the variable "start", e.g. find-a-recipe.php?course=salad&start=30 There can be any combination of these variables, meaning there are hundreds of possible search results URL variations. This all works well on the site, however it gives multiple "Duplicate Page Title" and "Duplicate Page Content" errors when crawled by SEOmoz. I've seached online and found several possible solutions for this, such as: Setting canonical tag Adding these URL variables to Google Webmasters to tell Google to ignore them Change the Title tag in the head dynamically based on what URL variables are present However I am not sure which of these would be best. As far as I can tell the canonical tag should be used when you have the same page available at two seperate URLs, but this isn't the case here as the search results are always different. Adding these URL variables to Google webmasters won't fix the problem in other search engines, and will presumably continue to get these errors in our SEOmoz crawl reports. Changing the title tag each time can lead to very long title tags, and it doesn't address the problem of duplicate page content. I had hoped there would be a standard solution for problems like this, as I imagine others will have come across this before, but I cannot find the ideal solution. Any help would be much appreciated.
