First, thanks Linda for mentioning me.
1. Description for the citations:
I would generally agree with Broland - having the same description everywhere is not the best option. However, it is also not a very smart option to have unique description everywhere, either. Is there a person who could summarize their business in 50 completely unique different ways, each within 150-250 symbols (not words)? I don't think so. That is why when asked this question, I suggest that unique descriptions are used as much as possible at least on the top 6-7 platforms, especially the ones that are more likely to rank for brand terms, such as Yellowpages, Yelp, Citysearch, Insiderpages, Merchant Circle. These are also the platforms that are (generally) most likely to be interacted with by actual people, so their usability would be of greater importance. And that is also why we normally ask for at least 3 different descriptions.
2. Spacing-out citations:
I don't really think this is necessary, because I have never seen any evidence of Google using citation "velocity" as a ranking factor. In the bottom of its system, Google is not able to use such a factor with as good accuracy as they would like simply because their local listings clusters are updated on a monthly/bi-monthly basis. Additionally, it takes different amount of time for different citations to be first indexed as pages, and then included in the business data index. This period depends on the popularity of the platform, trustworthiness of the platform, how often new content is added, and if Google has any official relationship for data exchange with the platform. So it is very possible that if you add a listing today to angieslist.com (for example), it might actually go into Google's business data index LATER than if you add a listing in 6 weeks on Citysearch. So spacing-out citations is rather useless.
3. Hiring someone from Fiverr/Elance/Odesk vs. hiring a professional
The cost will obviously be lower. However, citation building is not just about getting a bunch of listings on a bunch of websites. A very comprehensive research has to be completed prior to the start of the process in order to discover ALL currently existing citations for a business. And believe me, there is no business older than 2 months that doesn't have any citations. Additionally, there is practically no automated tool currently available that discovers all citations for a business. That is why in our research process we use the following:
- Yext Local Search Scorecard
- GetListed.org
- Whitespark Local Citation Finder
- Bright Local Citation Tracker
- SweetIQ's Local Marketing platform
In addition to these, we run manual checks both through Google, Bing AND through some of the websites that we know from experience feature a lot of listings that are generally not indexed by Google (for instance, Kudzu, Local.com, Insiderpages are indexed very badly; LocalEze and Axciom are not indexed).
Just my two cents
