Hi SEO experts, I need your help or your opinion what the wrong I done with my site. I have one arcade gaming site. The site is new. As I had been doing onpage and offpage SEO my website ranking was going up day by day for the keywords I targeted for. After some days my ranking for all keywords went down instantly and then after 2, 3 days my ranking come up to the actual ranking position. Again ranking goes down and now the ranking fluctuation frequency is being slow. Now all the keywords ranking down and sometime for few minutes I see the ranking come up. Also when ranking goes down targeted URL also change on SERP and sometime my old meta tag also shown on SERP. I actually can not find the actual reason what I done wrong with my site. Please help me.
