Welcome to the Q&A Forum

I notice that competitors who set up places accounts before Local (which I did not have the opportunity to do) do better in search for subcategories of specialties that aren't listed in the preset categories.  I'm sure Google will eventually deal with this, but I would say if you have the opportunity to include categories that aren't on the preset list, it may give you a leg up.

Obviously things like Mozrank, domain authority, relevancy signals, authority signals, and other fundamentals are a great starting ground, but I was wondering how people put value on a links.  How much time is a link from a page rank of x or a moz rank of y worth.  How much time, money (not in terms of paid links, but in terms of manpower, copyrighting required, etc.) is a link of a certain rank worth.

Obviously there is no exact answer to this question, but I'm very curious to see what people have to say in this regard.

Moz has a very comprehensive list of recommended firms here: [http://moz.com/community/recommended].  I can't personally speak for any of them, but the list seems well researched and vetted.  Hope this helps.

It's important to include a small logo, that way if the graphic is not correctly attributed to you, it is still associated with you or your company.  Include a small non-obtrusive logo on the bottom of the graphic.  Professional photographers, infographs, etc. usually include a logo, and perhaps a link.  Just be sure that including it doesn't take away from the graphic.

It's good practice to include spacing but Google can make the distinction.  That being said, I would recommend just using spacing and no pipes if you don't have space for three characters it looks much better.
