LSI and Partial Match and ranking stuck

I used 15 pbn （URL and Brand anchor text to my website home）and some web 2.0 links ( Generic anchor text to my website home)for my website, then I entered the #12 and stayed for a month. I re-optimized my money page, added the lsi keyword and tf*idf, and the ranking rose to #10. Now my ranking is stuck in #10 (my website is Ecommerce)

I want to improve my ranking, I am going to use the lsi keyword as the anchor text link to my money page
But when I use the lsigraph tool to query keywords, they are all partially matched lsi keywords.（dog t-shirt lsi keywords just like xxx tshirt）Will I be punished if I use such keywords?

I found that most blog anchor text suggestions are: brand url anchor text:xx% Generic anchor text xx% ...
I want to know this is for the entire site? Still homepage? If it is a money page, how should my anchor text ?

I would be grateful if you have any suggestions.

It's very difficult to rank for 1 specific keywords, regardless of your momentum. The way to go is targeting other related LSI not only in the page you want to rank (homepage for example), but in other articles thay may also rank for those keywords, and introducing some good exact match and LSI anchors in those pages to the main one. Over the time the OPR that your target page will get, will be good enough to rank by itself.
In the meanwhile you will be receiving a lot of visits to other pages, that will increase overall the interest of the site.
Also, don't forget that in the 1st page, what it does really matter is the CTR, links and onpage SEO is not that important anymore.
