Welcome to the Q&A Forum

I would agree with Tom.  I would imagine dashes would be better from an SEO side BECAUSE it is better from the user experience side, namely it is easier to read.  Think about what will read best when someone is looking at the search results.

You will not be penalized for not including titles and descriptions, but Google will auto-fill them for you. Takeshi's advice is sound if all you want is to not have these pages displayed in site links (the links under your domain when you google your domain's name). However, it sounds like what you are asking is to not have the pages displayed at all in SERPs ever. I don't quite understand the reasoning behind this, I must say. For example, if you work for Comcast and somebody googles "Contact Comcast" you should want them to land on your contact page. Same with the registration page, I would think.. That said, if you truly do not want those pages indexed you can disallow them in your robots.txt or add this tag to the header:

Hey there - I'm going to weigh in and just concur basically with Paul. Also just like to add a link to the wordpress resource post I did on Moz which breaks down a lot of the distinctions between tags and categories. Hope that helps too. Link

I have a couple businesses that target major cities, and their suburbs with multiple pages like this, and I've had great results.

It's all been said but here are a few more tips to get your going with the perfect page titles http://seoandy.com/optimisation/perfect-webpage-title/#sthash.lcH9PSFM.dpbs

Paul, Thank you for the help. You have confirmed everything I was thinking.

ok thanks Brett.

Thank you

This is what I thought it was, I just wanted to make sure that what I was thinking was correct.

Thanks for the help

Sadly, we can't make Google display rich snippets. All you can do is follow the best practices of implementing rich snippets, and leave it to Google to algorithmically determine they should appear. For the search phrase "phraseexpander", download.cnet.com is already displaying rich snippets. Therefore, the presence of snippets in the SERPS already may impact whether or not they are shown for your domain too.

I have now run a spider simulator and all the content was in there. Thanks for the tip!

ok thanks Baledea.

Thanks. Just wanted confirmation.

Hi vzPro, Absolutely. Schema for local is a very good thing to use whenever a physical address exists. Also, thought you might like to read a fairly recent article of mine on the topic of city landing pages. A lot of folks have told me it helped them to understand their opportunities.
