I've been on SEOmoz for about 1 month now and everyone says that depending on the type of business you should build up your website structure for SEO as 1st step. I have a new client click here   ( www version doesn't work)... some bugs we are fixing it now. We are almost finished with the design & layout. 2nd question have been running though my head. 1. What would the best url category for the shop be    /products/     - current url cat ex:   /products/door-handles.html 2. What would you use for the main menu as section for getting the most out of SEO. Personally i am thinking of making 2-3 main categories on the left a section where i can add content to it (3-4 paragraphs... images maybe a video).So the main page focuses on the domain name more and the rest of the sections would focus on specific keywords, this why I avoid cannibalization. Main keyword target is "door handles" Any suggestions would be appreciated.

I'm changing title and description several times throught 1-2 months...  will Google penalize me? I'm worried that testing several title and description ideas would affect the site rankings on google. Anyone had a problem with that... or can i continue testing as many titles and descriptions as i want?
