To show site name or not?

[Jon12345]

My discussion forum is shown in Google SERPS as follows:

UK Widgets Forums - Fastest growing UK ... - WidgetsBuzz

What I would like to know, is should I be showing the "WidgetsBuzz" bit after the hyphen? Or should I omit it?

By default, vbulletin forums seem to have it setup to show, but I am wondering if its just going to dilute the keywords. I think Google itself shows "Google" after the hyphen on some entries in SERPS where Google's properties are shown.

In my case, if you type "uk widgets forums" into Google, the top site doesn't show the site name.

So, what is deemed best practice?

Thanks,

Jon

Long time debate, and not all that important for ranking, IMO, but potentially important for CTR and/or branding when you do rank. Except for Home Page or perhaps a major category, trademark, most prefer the brand name at the right, not the left. Beginning the page title with the most important and differentiating language describing the page is a service to your readers.

Google will often add it even if you don't.

As netmeg said, Google may add it.

Recently launched a site w/o the site name in the title tag and the site name is showing in the Google results.
