If you have old wordpress databases sitting around, it would only be a problem if you still have the WP that's connected to them still around also. If so, anyone (or a bot) that visits the old installs would be pulling data from the DB and thus draining a small fraction of resources away from your current install of WP. This shouldn't be a problem, considering you mentioned they are experimental and I assume are not in production. The more pull on the database, the more bogged down your server could become at a given time; usually not an issue unless you get sudden spikes of traffic on your experimental WP installs; which would slow production WP down. Hope that made sense.

To make it look good they hired a good designer and spend time and money doing CRO.  You can see in the links below the technologies behind the scenes. However produce a great website is not about the technology it's about knowing the theories about designing a website.  A professional using only Microsoft Pain as tool will do far better than some one with all the tools in the world  that only knows how to use the tool, one can master every single feature of Photoshop for example and still  make poor designs is not about knowing the tools is about knowing design. http://builtwith.com/?http%3A%2F%2Fwww.quicksprout.com%2Fthe-advanced-guide-to-seo%2F http://builtwith.com/?http%3A%2F%2Fbacklinko.com%2Flink-building

Hi Ruchy, I am not following as to why you want to add the nodollow. If you are doing business with him and there is no money in exchange, then there is no reason to nofollow. If there is money changing hands in any way, add a nofollow. If there is not, there is no reason to add one. Have a great day!

Happy to assist, Dario. I'm interested to know if you were finally able to make your upgrade directly to a dedicated IP address in your new account? Paul
