Joel, i prefer www version cause i think from a technical perspective, there are several benefits to including the WWW.

• Ability to restrict cookies when using multiple subdomains. Cookies of a main domain (i.e. example.com) are sent to all subdomains: If you are going to have subdomains for other purposes (blog for instance), you may want to differentiate the sites and have a www prefix for the regular site.
• WWW actually MEANS something. As mentioned above, WWW is a hostname, and the hostname names the specific service being used a computer network; WWW names the web service for a domain.
• Using the WWW hostname allows for easy segregation in the file structure of your website. Everything in the “www” folder (and at the www.example.com domain) is directly related to serving the site to the public. This allows for simple root-level site organization, eg you could also have a dev folder and have a subdomain dev.example.com for your development site, etc.
• More flexibility with DNS. Your domain’s “Zone” file controls where traffic to your domain is directed and using the non-WWW version of your domain can complicate things.

you may still want to use the WWW simply because it’s conventional to do so. On a business card, the WWW clearly conveys, This is our address on the World Wide Web. People are used to looking for, and seeing, the WWW and that’s sufficient reason for many to stick to the convention

What do you think about Google URL parameters? http://support.google.com/webmasters/bin/answer.py?hl=en&answer=1235687

A new client ( aqmp.com.br/ )call me yestarday and she told me since they moved on magento they droped down more than US$ 20.000 in sales revenue ( monthly)...

I´ve just checked the webmaster tool and I´ve just discovered the number of crawled pages went from 3.260 to 75.000 since magento started... magento is creating lots of pages with queries like search and filters. Example:

1. http://aqmp.com.br/acessorios/lencos.html
2. http://aqmp.com.br/acessorios/lencos.html?mode=grid
3. http://aqmp.com.br/acessorios/lencos.html?dir=desc&order=name

Add a instruction on robots.txt is the best way to remove unnecessary pages of the search engine?

use vimeo as default and Youtube for top3 videos. Youtube will increase trafic for the site and your site will use vimeo best quality videos

Just perfect Moosa. Thanks a lot 4 your thoughts !-)

Hi there !-)

I´m helping a friend who has a e-commerce about nail polish in Brazil. I´m a little in doubt about the urls and folder structure. Two questions:

1. There are 10 products per category and 50 categories. Should I put them all in the root folder or creat 2 major categories ( 25 sub-categories each one)?

2. Whats the better product page url ( the store has around 500)

• nailpolish.com/IMPORT/BRAND/NAME-OF-THE-PRODUCT OR
• nailpolish.com/COMPLETE-NAME-OF-THE-PRODUCT

Whats the best recomandation?
