what if your site name / brand is your main keyword, wouldn't using it at the end of title tag lessen the weight of the keyword for your site or even get you penalized?
here's an example of what I mean,
page title: Fresh Wholemeal French Bread Sticks - Bread Sticks
Would google see it as spamming if a site had 1000 pages with the term at the end of each page title? Would they know that's what your site name is?
