Short description same on every Product Page

[thepan]

Hello

 

On all my product pages I got a description that is unique on every page and at least 500 characters long. Straight after this I insert an additional text that is the same on every page.

Is this bad for my pageranking?

I also have a tab with some delivery information that is the same on every page.

Also I would like to know if the Product Tags have any influence on the pageranking.

Are they important for the on site search?

500 character for a unique description is fine
Add same content on all pages. Its not Good. Tell me the length if its just 100 character then fine otherwise the best is to add this infomation in sperate page and place link in every product page.

Product Tags are very important for SEO ranking, Add title , description properly by using your main in them keywords.
