Hello. A lot of the products I sell on my e-commerce site are very technical. I decided to add PDF data sheets, manuals etc on each of the product pages to improve the customer experience. Now I am not sure if it was the best thing to do.  I have noticed a couple of times that the PDF is out ranking the product page in the SERP.  For a few products, the PDF ranks but the product page doesn't.  Anyone got any ideas?

Hi Just wondering what people think of using mega menus for navigation? We have used them on our new site http://nicontrols.com/uk/ When I run the site through the excellent SEOMoz campaign tools I see that we have too many on page links. I now believe the menu is good for customers but maybe not for link juice. Anyone got an ideas? Do I remove the mega menu or just reduce the number of links? Many thanks David

Hello, I have a question how about how google sees dashes, slashes, full stops etc. I am new to SEO so this might be dumb. I sell refurbished printer parts. The majority of people search for the part number in google. A typical part number might be "04.F5/S3A YA50" .  A customer might search for "04F5S3A YA50" or "04.F5/S3AYA50" or "04.F5/S3A YA50" or "04.F5/S3A-YA50". They aren't radically different but seem to effect the rankings. At the moment I use the following stucture for the meta tiles, descriptions etc 04.T5/S3A YA50 (04T5S3AYA50) by OEM | mysite Buy refurbished OEM 04.T5/S3A YA50 (04T5S3AYA50). Free next day delivery. 12 month warrnanty on all parts. www.mysite/4F5S3AYA50 Part number (Part number no spaces) by OEM | Mysite Generic text Part number (Part number no spaces) text www.mysite/(Part number no spaces My questions, should I try to include all the different ways a customer might search for a part number in my meta title, description, url etc.  Or should I try to include within the content of the page. Many thanks
