Welcome to the Q&A Forum

Hi, It sounds as though you have done everything right. BUT - (this is a bug-bear of mine) Google doesn't display breadcrumb rich snippet info on https pages. Also, some directories won't link to https pages (not ever seen this as a major issue because it's usually the spammy directories that do this) Amelia

Just took a look at that site, and it offers unlimited monthly submissions to post guest blogs.  I can't help but thing this is akin to a public blog network which with the posting limits will be full of spammy posts. I keep an eye out on http://bloggerlinkup.com for relevant posting opportunities on guest blogs myself.  Sure, you won't get many opportunities that are in your niche, but you can find some real sites to post on.  I prefer quality over quantity.
