Duplicate content on different pages.

I have a system website, which has a great site lots of information,
I used many small, from a large content of the page.
All pages are logo, company information.

I want to ask it for affect seo pages - the content.

Comments are always welcome. for help.

 

Many people says that duplicate content can harm your website but I think that is just only a myth.

 

If the content on all the pages is same then it would be a duplicate content problem for your website, you will need to change it so that it doesn't afftect your rankings.

 

I only make a reasonable title, because there are many posts related content, I want each article has a different title, so there really is acceptable.

 

Have duplicate content on a same domain is not an issue from Search Engine point of view but it will effect your page rank. Suppose you have two pages with same content, the search engine has indexed both the pages. When someone search for similar content then sometime page 1 will appear and sometime page 2 will appear in the result page.

Except this there is no issue using duplicate content.

 

Anyhow, duplicate content is to advocate. It will affect the index of your website.
