Two questions about my sites

Hello,

This is my first post in BHW. Hoping to get your attention.
I have two question about my site.
Question one:
When i search my site in Google,but it does not show my official site. This situation lasted for more than a month.


Question two:
There are some keywords ranking such as "925 silver jewelry wholesale" are disappeared, also include other sites.
Youtube occupy a lot of the second page rankings, The situation is completely different two months ago.
But when i search as "925 silver wholesale jewelry" ,Google show my website and others normally.


Next,This is my viewpoint:
1.I use this website seo tool (Semalt) to check keywords ranking,Some problems may arise.
2.I did too much anchor link about "925 silver jewelry wholesale"

Could you give me some advices to fix this ?
Could you give me some seo advices to improve my site ?

Thank You!
Ben

run site:www.yourdomain.com
Then you will see if you have been indexed in the first place, which is the most likely reason

check if your site is indexed or not, and i did not understand your second question !
