Does duplicate content penalize the whole site or just the pages affected?
-
I am trying to assess the impact of duplicate content on our e-commerce site and I need to know if the duplicate content is affecting only the pages that contain the dupe content or does it affect the whole site?
In Google that is. But of course. Lol

Thanks Tom.... Very valuable info.
A bit of background: we are running an e-commerce site - so I'm dealing with various forms of dupe content:
- Descriptions that are copy pasted from manufacturers - e.g, replicas elsewhere - we are addressing this by writing our own content.
- Dupe content between pages due to the products only change in colour or size - I am going to make these configurable products, so group them into one page.
- URL params - this is a nightmare! Basically faceted navigation that is causing the same page to show very near similar content under different URL's.
Anyway, slowly fixing these - just seems like Google is painfully slow to respond to our work on improving things. Hence the question...

Hi there
In theory, the penalty can be either site-wide or page specific. The majority of the time I've site-wide penalties.
A good way to check is to run your analytics data using the Panguin Tool - which will tell you if traffic drops have coincided with major algorithmic updates.
Similarly, the Chartelligence Chrome Extension allows you to measure traffic for your landing pages in Analytics. Log into analytics, look at the landing page you wish to test and then activate the extension. It will show you algorithm updates on your timeline, so any drop that coincides with an update may suggest that the particular page in question has been penalised.
Hope this helps.

Penalties for duplicate content
Hello!We have a website with various city tours and activities listed on a single page (http://vaiduokliai.lt/). The list changes accordingly depending on filtering (birthday in Vilnius, bachelor party in Kaunas, etc.). The URL doesn't change. Content changes dynamically. We need to make URL visible for each category, then optimize it for different keywords (for example city tours in Vilnius for a list of tours and activities in Vilnius with appropriate URL /tours-in-Vilnius).The problem is that activities overlap very often in different categories, so there will be a lot of duplicate content on different pages. In such case, how severe penalty could be for duplicate content?

Possible to Improve Domain Authority By Improving Content on Low Page Rank Pages?
My sites domain authority is only 23. The home page has a page authority of 32. My site consists of about 400 pages. The topic of the site is commercial real estate (I am a real estate broker). A number of the sites we compete against have a domain authority of 30-40. Would our overall domain authority improved if we re-wrote the content for several hundred of pages that had the lowest page authority (say 12-15)? Is the overall domain authority derived by an average of the page authority of each page on a domain? Alternatively could we increase domain authority by setting the pages with the lowest page authority to "no index". By the way our domain is www.nyc-officespace-leader.com Thanks, Alan

Cross Domain duplicate content...
Does anyone have any experience with this situation? We have 2 ecommerce websites that carry 90% of the same products, with mostly duplicate product descriptions across domains. We will be running some tests shortly. Question 1: If we deindex a group of product pages on Site A, should we see an increase in ranking for the same products on Site B? I know nothing is certain, just curious to hear your input. The same 2 domains have different niche authorities. One is healthcare products, the other is general merchandise. We've seen this because different products rank higher on 1 domain or the other. Both sites have the same Moz Domain Authority (42, go figure). We are strongly considering cross domain canonicals. Question 2 Does niche authority transfer with a cross domain canonical? In other words, for a particular product, will it rank the same on both domains regardless of which direction we canonical? Ex: Site A: Healthcare Products, Site B: General Merchandise. I have a health product that ranks #15 on site A, and #30 on site B. If I use rel=canonical for this product on site B pointing at the same product on Site A, will the ranking be the same if I use Rel=canonical from Site A to Site B? Again, best guess is fine. Question 3: These domains have similar category page structures, URLs, etc, but feature different products for a particular category. Since the pages are different, will cross domain canonicals be honored by Google?

Interlinking from unique content page to limited content page
I have a page (page 1) with a lot of unique content which may rank for "Example for sale". On this page I Interlink to a page (page 2) with very limited unique content, but a page I believe is better for the user with anchor "See all Example for sale". In other words, the 1st page is more like a guide with items for sale mixed, whereas the 2nd page is purely a "for sale" page with almost no unique content, but very engaging for users. Questions: Is it risky that I interlink with "Example for sale" to a page with limited unique content, as I risk not being able to rank for either of these 2 pages Would it make sense to "no index, follow" page 2 as there is limited unique content, and is actually a page that exist across the web on other websites in different formats (it is real estate MLS listings), but I can still keep the "Example for sale" link leading to page 2 without risking losing ranking of page 1 for "Example for sale"keyword phrase I am basically trying to work out best solution to rank for "Keyword for sale" and dilemma is page 2 is best for users, but is not a very unique page and page 2 is very unique and OK for users but mixed up writing, pictures and more with properties for sale.

Duplicate page content errors stemming from CMS
Hello! We've recently relaunched (and completely restructured) our website. All looks well except for some duplicate content issues. Our internal CMS (custom) adds a /content/ to each page. Our development team has also set-up URLs to work without /content/. Is there a way I can tell Google that these are the same pages. I looked into the parameters tool, but that seemed more in-line with ecommerce and the like. Am I missing anything else?

404 for duplicate content?
Sorry, I think this is my third question today... But I have a lot of duplicated content on my site. I use joomla so theres a lot of unintentional duplication. For example, www.mysite.com/index.php exists, etc. Up till now, I thought I had to 301 redirect or rel=canonical these "duplicated pages." However, can I just 404 it? Is there anything wrong with this rpactice in regards to SEO?
