Declining website

[bradenodell181]

While researching for keywords, I encountered some strange things. Therefore, I would like to share it with all the members of this forum. There were differences in results in different sites. In the beginning, my site was announced for many competitive keywords but recently I noticed a decline in the ranking of my site. However, I do not know the reason for such a rapid decline of my site. Another strange thing that I noticed was that the home page of the blog was in the first place. Can anyone help me to solve out this problem?
