Regarding SEO question in VM

[dmtvision]

Hi,
I have joomla 2.5 and VM 2.0.12:

1) I want to  set up the Site name to all the page titles in VM . how is it possible?
2) I want to copy the first sentence of page description of the product to the  Product Meta Description of VM automatic. How is possible ?

I am trying find solution to these problems, whether i need to buy a component or any other solutions.
Thank you very much!

1) There is a setting for this in the Joomla configuration (applies to non-VM2 pages, too)
2) There are might be a tool for this in the Joomla extension directory. However since your sentences won't be all of the same length, it is better to do this manually for each product. The number of characters for the meta desc should be below 160 characters for the search engines.
