Duplicate Content can hurt the SEO of the blog. For example, When Google bot finds the same content on multiple locations, give the signal to google that someone scraped the content. Google start to identify the original source to give SEO point (link juice) and deduct or reduce the SEO point of the overall domain who copy it because you do not follow the google Guidelines

If you write a content on your website “ABC.com” and someone copies it and Publish its own website “DEF.com”. By accidently Google select DEF.com website publish original content and you copy from it. Then what you do now? Don’t worry, Today article is on Duplicate content, to help you to understand how you can deal with the duplicate content issue and fix it for SEO.

Introduction Duplicate Content

Many people assume that creating multiple pages or similar copies of the same page will either increase their chances of getting listed in search engines or help them get multiple listings, due to the presence of more keywords. In order to make a search more relevant to a user, search engines use a Duplicate Content Filter that removes the duplicate content pages from the search results, and the spam along with it.

Content Filter

In order to understand the duplicate content filter, First, we must have to understand the concept of the duplicate content penalty. When we refer to penalties in search engine rankings, we are actually talking about the SEO point called link juice that are deducted from a page in order to come to an overall relevancy score.

But in reality, duplicate content pages are not penalized. Rather they are simply filtered out from the search engine, the way you would use a sieve to remove unwanted particles. Sometimes, “good particles” are accidentally filtered out by the search engine.

The Three Biggest Issues with the search engine to deal with the Duplicate Content issue are;

  1. Search engines don not know which version to include/exclude from their indices;
  2. whether to direct the link juice to one page or keep it separated between multiple versions
  3. Search engines don’t know which version(s) to rank for query results

Difference Between Google Penality and Filter

Knowing the difference between the Google penalty and filter, you can now understand how a search engine determines what duplicate content is. Duplicate content that is filtered out:

  1. Scraped ContentScraped content is the content that is copied from the other website and repackaging it to make it look different. This is called scraped content. Either you place it on your another domain or someone copy from your domain, if google found two same content access by two different URL then google get puzzled and select any one of them and another page just filter out. I will explain at the end of the article how to google pic the best content.
  2. E-Commerce Product Descriptions – Many eCommerce sites out there use the manufacturer’s descriptions for the products, which hundreds or thousands of other eCommerce stores in the same competitive markets are using too. This duplicate content, while harder to spot, is still considered spam and marked as a penalty.
  3. Web sites with Identical Pages – If google finds two websites with the same page or similar to each other, google consider it is as spam.  Affiliate sites with the same look and feel which contain identical content.

How Duplicate Content Filter Work?

when a search engine bots crawl a website, it reads the pages and stores the information in its database. Then, it compares its findings to other information it has in its database. Depending upon a few factors, such as

  1. When google detect duplicate content, then google group the duplicate URLs into one cluster.
  2. Select what we think is the “best” URL to represent the cluster in search results.
  3. Then consolidate properties of the URLs in the cluster, such as link popularity, to the representative URL.
Consolidating properties from duplicates into one representative URL often provides users with more accurate search results.

How To Deal With Duplicate Content

There are several ways to deal with the duplicate content on the web, here is a list of some common content issue with its solution to fix it;

  1. Copied Page
  2. Unoptimized category
  3. Duplicate Product Information
  4. HTML Error
  5. Cross Domain

Copied Page

The Situation: Let’s start with the example, I’m a site owner who has found a great piece of content on a different website and I would like to share this content on my website.

The Issue: The issue you’ll face is that this content is going to be valued poorly or count as a scraped content on your site and may contribute to an overall domain score quality drop.

The Fix: A cross-domain  canonical tag is the only fix here. You’ll need to add a canonical URL tag to the page indicating that the original source of the content is at a different location.

<link rel=”canonical” href=”http://www.abcwidgets.com/copied-article.html”/>

This will tell the engines that you know the article is copied, it is intentionally placed on your site and all link juice to that page should pass to the original location of the article.

Unoptimized Category

The Situation:- If one article is in under two categories, then this can be assessed by two different URL.

The Issue:-   This puzzle the google to select which Version of the page is original and where to pass the link juice.

The Fix:- Select SEO friendly URL as your referral URL and Canonical tag in it. To avoid this in future Remove and add “noindex but dofollow tag for the category.

Duplicated Product Information

The Situation: You run an e-commerce site selling blue widgets from a variety of manufacturers. These manufacturers provide you with product information (titles, descriptions, specs, and images) to post on your site.

The Issue: The manufacturers are also providing the exact same information to everyone else who’s selling their products.

The Fix: While specs remain the same and duplication is acceptable across multiple sites, you need to set your site apart. This will generally involve writing new product descriptions, taking new photos, and hopefully adding content unique to your site such as reviews.

HTML Duplicate Tag

The Situation: Whenever we change the URL of the existing post or edit the URL,

The Issue: Page can by access by two different URL, First is old one and second new one,

The Fix: Go to HTML Improvements under google webmaster tool and remove the old one by using removal tool in the webmaster tool,

Cross Domain

The Situation: Suppose you have a two-domain and you publish the same content on both side.

The Issue: Google found same content, google take action and filter out one of them

The Fix: Use canonical URL tag to tell google which one have to index.
