From a quick scan through, I can't see anything horribly wrong (ok, false reviews are a little odd) with what's being done. I would say that there's probably not as much benefit to the directories that a lot of people think.
Most directories know people are using them for a boost to SEO, so they
counteract it by tagging the link back to the site with "nofollow". This basically means Google will completely ignore it.
Of course, there's nothing wrong with making yourself visible to humans over Googles SEO by being in the places your clients will look.
Stuff like having a Google+ page is only really useful if you use it, same as Facebook and twitter etc. If you're just looking for an SEO hit, it might work.. but personally, providing something interesting for clients to return to (be it a blog or whatever) is the real way to get people back to your site!
