www or not www - when installing Prestashop download what is best Please help?

[Prestfortime]

Hello,

 

I have the option of creating Prestashop.

 

I'm given 2 options -

 

1) Install with 'www' in front of domain name.  So it goes http://www.domain.com

 

2) Install 'without www' in front.  So it goes http://domain.com

 

Can you let me know what is the best to go for?  I am thinking of Google Pagespeed and want the fastest/best SEO option.

 

Thanks a lot.

In an update to my above post :

 

I notice that when I put the "http://" (without www) into Google PageSpeed Insights it says it's a faster website than when I put in http://www.

 

When I installed Prestashop download I installed onto http:// but didn't install it with the http://www.

 

Should I change it to have "www" infront?

This is just a personal preference -- I prefer not to use www. That seems to be the way most people are going at least in my area of the world.

Whichever you choose to go with the other one should always be redirected to the chosen one so that people end up at the right place regardless of what they enter.
