What is Website Duplicate Content and how to avoid problems

duplicate content

Most of website in the internet has problems with the Duplicate content issue. This websites are built by CMS or a webmasters that create a Duplicate content and do not know what is that.

Duplicate content – when content of a page are more then on 1 website or on many pages of a website. It’s better to explain using example.
Let’s take Boonex Dolphin CMS and its real demo website boonex.us. I’ll show you all about Double content using this demo website.

1 – The same Content on many websites.
let’s take boonex CMS standard page http://www.boonex.us/terms_of_use.php then take a line of a text and do search in google service that allows members to create unique personal

You will see that there are about 810 websites with the same text. That means that google has over 800 same page in the index and if you have the same page it could be taken as a Search engine Spam or plagiarism. When Google give you PR he takes into consideration many parameters and Duplicate content is an important one.

You need to change all standard text ( if you are using any CMS ) on your website to a unique one to avoid Duplicate content on your website. Try to fill your website with unique content and you will soon get your search engine traffic.

2- The same content on a website.

This is more important then the first part as Google and others can think that you made many web pages to do SEO spamming and give you penalties for PR.

Now what can create duplicate content:

  • canonical issues (www and non-www version);  http://www.flashdaweb.com and  http://flashdaweb.com
  • pagination when different pages have identical titles and meta description; – this is when you set the same Meta and Title tags for many website pages.
  • various versions of the home page (e.g. www.site.com and www.site.com/index.php or www.site.com/index.php?mode=top_art ); good example is http://www.boonex.us http://www.boonex.us/index.php?ppoll_mode=top
  • incorrect internal navigation creating several URLs to one and the same page (e.g. www.site.com/page.php?id=567 and www.site/category/page.php?id=567); etc

Why is it important to get rid of duplicate content issues?

Google has mostly figured how to sort this out. It will drop one version and index and rank another one. But still internal content duplication may result in a few issues:

  • decreased crawl rate as Googlebot is kept busy crawling unnecessary identical pages;
  • a wrong version of the page ranked which results in bad user experience (e.g page 2 is ranked instead of page 1);
  • delayed ranking of newly launched sites.

    The best and competently Bonnex SEO guidance ever! Download the robot.txt and the script to get a much better google love. Duplicate content is a huge problem in Dolphin and thats a fact. Its also a fact that DC is the reason why the Boonex communities have so small PRs. OK, Boonex.us have a good one but they have thousands of good trusted backlinks. The trust of our small communities is spliting on the different indexed pages. This Tool is defintely the best and extensively Dolphin SEO Tool. So it called All in and thats true!

    In regards to the duplicate content part of this blog post, I personally use the http://www.copygator.com website to find and stop duplicate content:

    1. it’s automated and brings me results instead of me searching for duplicated content. All i had to do was submit my feed and it started monitoring my feed showing me who’s republished my articles on the web.

    2. i get notified by email so it contacts me when it finds copies of my articles online.

    3. i use their image badge feature to alert me directly on my website when my content is being lifted.

    4. it’s a free service as opposed the “per page” cost of copyscape/copysentry.

    Google Search Engine gives penalty for the web sites having dublicate content therefore for Google Seo,you should avoid dublicate content.Always you should put original and attractive content to site to have a better Search engine rank,especially on Google. Google never forgive dublicate content,on the other hand,a web site having original unique content,has better position on Google search engine,do not forget this.

    Another way of avoiding this problem within a site is with the use of a duplicate content checker. There are plenty of these available online and all it requires is you to enter the URL of the site that you wish to be analyzed. Within a matter of minutes, you can see if there are any problems and if so, make the necessary changes.
