A tool that I did not know

http://www.positeo.com/check-duplicate-content/

allows to check which other sites displays similar content for a page.

What is acceptable ?

Hello,

Personally I use positeo.com/check-duplicate-content/ and http://www.plagium.com/.

Positeo is a bit limited in terms of the number of words (150-170 max) but remains a very good tool is tool.

Plagium is also interesting but it is still paying.

I recommend you use both. .

This site (positeo.com) does not give correct results (When I did my tests it always showed me an error)

I think the best way to test and type a text from your site in google

The quota that between the limits is not mentioned by googling but we can say arround of 35% and 45%

If you use texts that you have written yourself, you will not worry about duplicate content

Hello,

 

I think the best way to have no duplicate content is :

1 - Create original product descriptions

2 - Create unique Title and Meta tags

3 - Care exactly in the list of products

4- Create canonical URLs and not index all the pages of your ecommerce site

5- Make 301 redirects in case of site redesign 6. Use duplicate content measurement tools

 

Some tools  :
PlagSpotter, to locate online pages that copy your content. You can also use Copyscape, a reference tool.

Webconfs, which determines the similarity rate between two content already online. You can also use the Duplicatecontent tool.

Web SEO Analytics, which calculates a duplication rate between the content of two URLs.

Positeo, which allows among other things to check the duplicate rate of offline content (which has not yet been published on the internet).

Plagiarisma allows the thing. DupeCop, which allows to compare the duplicate between several offline texts.

Siteliner, which allows to know the internal duplicate rate on your site.

 

@Josephine, welcome !

Thank you, interesting.
