Why do I get duplicate content errors just for tags I place on blog entries?
-
I the SEO MOZ crawl diagnostics for my site, www.heartspm.com, I am getting over 100 duplicate content errors on links built from tags on blog entries. I do have the original base blog entry in my site map not referencing the tags.
Similarly, I am getting almost 200 duplicate meta description errors in Google Webmaster Tools associated with links automatically generated from tags on my blog. I have more understanding that I could get these errors from my forum, since the forum entries are not in the sitemap, but the blog entries are there in the site map.
I thought the tags were only there to help people search by category. I don't understand why every tag becomes its' own link. I can see how this falsely creates the impression of a lot of duplicate data.
As seen in GWT:
Pages with duplicate meta descriptions Pages [ Customer concerns about the use of home water by pest control companies.](javascript:dropInfo('zip_0div', 'none', document.getElementById('zip_0zipimg'), 'none', null);)
/category/job-site-requirements

/tag/water-use

Nice if you can get your tags to reflect the broad range of topics covered by your site, but I think sometimes it can give a visitor the perception that your content is a little thin when you only have one article against each topic.
Say you're reading an article, you see that it's tagged with the topic you're interested in, click on that tag and only get the one article that you've just read.
When deciding on tags to use, try and think of how your visitors may wish to explore your content. Remember to try and maintain an external perspective and use tags that are meaningful to your visitors.
If you've got the time and enough traffic to give you the info, you could use your analytics data to see how people are using tags vs. site search for example.
Of course, as you point out, this doesn't have anything to do with the duplicate content problem.

Doug, thank you so much for responding quickly. I will have to explore the archive. I really haven't ever explored this section. You've given me a new place to research and I appreciate that.
As far as reducing the number of tags, that I don't understand as being an issue. Because if I am doing something wrong, i.e. presenting the whole article via tags rather than references to it, that is the problem, whether I have 2 tags or 20 tags. I want to find a solution that will solve the core issue regardless of the number of tags created.
Is that a different reason that you suggest reducing the number of tags? I have heard around town that it is good not to have so many tags, but shouldn't I create them if a post covers a wide range of topics. For example, if I wrote one post about a trip to Europe, chosing not to divide it into 15 posts for 15 countries, wouldn't I want to create a tag for each of the countries I mention in the post?
Doug, thanks again.

As you mention, you use tags to give visitors the ability to browse articles with that cover the same subject matter. Normal practice would be to give the visitor a list of articles that have been tagged with this term.
A list of articles shouldn't flag up as a duplicate of any of the other article pages.
However, I notice that on a couple of the tag pages I took a look at that I just get one article being displayed, and being displayed in full. This is obviously going to be a duplicate of the original article.
I suspect that this is because for a number of the tags there is only one article to be returned.
I would look at how you are presenting articles when listed in the "tag archive" view and perhaps only display the introduction to the page with a link to the full article.
You may also want to think about the tags you are using so that you have fewer tags with only one article.
Hope this helps!

What is the process for allowing someone to publish a blog post on another site? (duplicate content issue?)
I have a client who allowed a related business to use a blog post from my clients site and reposted to the related businesses site. The problem is the post was copied word for word. There is an introduction and a link back to the website but not to the post itself. I now manage the related business as well. So I have creative control over both websites as well as SEO duties. What is the best practice for this type of blog post syndication? Can the content appear on both sites?

Duplicate Content Due to Pagination
Recently our newly designed website has been suffering from a rankings loss. While I am sure there are a number of factors involved, I'd like to no if this scenario could be harmful... Google is showing a number of duplicate content issues within Webmaster Tools. Some of what I am seeing is duplicate Meta Titles and Meta Descriptions for page 1 and page 2 of some of my product category pages. So if a category has many products and has 4 pages, it is effectively showing the same page title and meta desc. across all 4 pages. I am wondering if I should let my site show, say 150 products per page to get them all on one page instead of the current 36 per page. I use the Big Commerce platform. Thank you for taking the time to read my question!

Duplicate content issue with trailing / ?
Hi ,I did a SEOmoz Crawl Test and found most pages show twice, for example: A: www.website.com/index.php/dog/walk B: www.website.com/index.php/dog/walk/ I've checked Google Analytics and 90% of organic search traffic arrives on the URLs with the trailing slash (B). Question 1: Can I assume I've a duplicate content problem? Question 2: Is it best to do 301 redirects from the 'non trailing slash' pages to the 'trailing slash pages'? Question 3: For some reason every web page has a '/index.php' in it (see A&B) above. No idea why. Should it be a SEO concern? Kind regards and thank you in advance Nigel

Duplicate title tags and meta description tags
According to GWT, it seems that some of the pages on my website have duplicate title and meta tags. The pages identified by Google are nothing but dynamic pages: http://www.mywebsite.com/page.php

http://www.mywebsite.com/page.php?param=1
http://www.mywebsite.com/page.php?param=2 The thing is that I do use the canonical link tag on all pages. Should I also use the "robots noindex" tag when the page is invoked using a GET parameter? Again sorry for my english. Thank you, Stephane1 -
What is the best practice to handle duplicate content?
I have several large sections that SEOMOZ is indicating has duplicate content, even though the content is not identical. For example: Leather Passport Section - Leather Passports - Black - Leather Passposts - Blue - Leather Passports - Tan - Etc. Each of the items has good content, but it is identical, since they are the same products. What is the best practice here: 1. Have only one product with a drop down (fear is that this is not best for the customer) 2. Make up content to have them sound different? 3. Put a do-no-follow on the passport section? 4. Use a rel canonical even though the sections are technically not identical? Thanks!

Duplicate Page Titles and Content
I have a site that has a lot of contact modules. So basically each section/page has a contact person and when you click the contact button it brings up a new window with form to submit and then ends with a thank you page. All of the contact and thank you pages are showing up as duplicate page titles and content. Is this something that needs to be fixed even if I am not using them to target keywords?

Duplicate content handling.
Hi all, I have a site that has a great deal of duplicate content because my clients list the same content on a few of my competitors sites. You can see an example of the page here: http://tinyurl.com/62wghs5 As you can see the search results are on the right. A majority of these results will also appear on my competitors sites. My homepage does not seem to want to pass link juice to these pages. Is it because of the high level of Dup Content or is it because of the large amount of links on the page? Would it be better to hide the content from the results in a nofollowed iframe to reduce duplicate contents visibilty while at the same time increasing unique content with articles, guides etc? or can the two exist together on a page and still allow link juice to be passed to the site. My PR is 3 but I can't seem to get any of my internal pages(except a couple of pages that appear in my navigation menu) to budge of the PR0 mark even if they are only one click from the homepage.

E-Commerce Duplicate Content
Hello all We have an e-commerce website with approximately 3,000 products. Many of the products are displayed in multiple categories which in turn generates a different URL! 😞 Accross the entire site I have noticed that the product pages are always outranked by competitors who have lower page authority, domain authority, total links etc etc. I am convinced this is down to duplicate content issues. I understand there is no direct penalty but how would this affect our rankings? Is page rank split between all the duplicates, which in turn lowers it's ranking potential? I have looked for a way to identify duplicate content using Google analytics but i've been unsuccessful. If the duplicate content is the issue and page rank is divided am i best using canonical or 301 redirects? Sorry if this is an obvious question but If i'm correct we could see a huge improvement in rankings accross the board. Wow! Cheers Todd
