Anyone who does SEO also focuses on the content, how to get the reader to receive the fastest topic, how to write how to understand it best. In particular, attractive content will make the article on your website highly appreciated. But duplicate content is inevitable. In terms of internal factors, this error is caused by the source system. So what content are you in, and how do you handle them? Read the article below to get more information about content overlap types.

1. Duplicate forms www and non wwww:

This form is quite common and many people already know it. If your page has this error, how many index pages will have errors due to error affecting the whole page. To solve this problem, you can use 301 redirects or use WMT to specify preferred domain names.

2. Home page duplicate:

Easy to meet with the default link page is website.com/home , website.com/index.php , website.com/index.aspx . While it still receives the default website.com. This case is similar to case 1 or canonical can be used for the main link.

3. Print page duplication:

For sites that allow you to print articles without paying attention, Google will easily index the whole page. What is easy to imagine here is that the printed page has a different content than the detailed article. With this error you can use the canonical tag to specify the main link, using a robots tag or robots.txt file to stop indexing.

4. Duplicate form due to filtering conditions:

This form often occurs with more sales sites. When in the list often have filtering conditions such as: low to high prices, high to low prices, freeship, filtered by product attributes . Not to mention filtering combination of conditions but order of island conditions together. If your code generates different links with different filtering conditions? A duplicate error occurred. So what to do?

Handling in this case is quite diverse. For example, by attribute filtering, it is possible to create subcategories to have more standard landing pages. Of course, provided your products are diverse enough and you need to optimize them after breaking down the category.

But what if your product is not diverse enough to divide the catalog or you can't optimize? Not all the way out, but you can stop indexing them via WMT with blocking parameters (when you are SEOer not too much about code). If you are technically active, you can do canonical tags on the main link or index blocking with the robot tag.

5. Form of duplicate content due to pagination:

This form, although many people know it, but many people have it. The paging of news and products if not processed, you will see error messages in WMT always through the improvement section of the HTML section of the title and description.

With this type of google recommended we should use the rel = "next" and rel = "prev" tags.

6. Incomplete form of duplication:

Usually happens with pages that use the free tag mechanism or have an unstructured portfolio structure. This is a common format for wordpress sites that have no clear management mechanism for tags and categories. You already have a category of "A-type products" that you have a tag of "Category A products", or more specifically the "Baby items" and Tag "baby supplies" list then what is up. Understanding is that your A-class product is 2 pages in existence, talking about it. It is not exactly a 100% duplicate content but it is a similar content, it will also directly affect the quality of your website.

Duplicate content by tag

You need to configure the directory tree structure for your website and need a strict keyword management mechanism to avoid duplication due to unreasonable tagging.
