There's a sudden drop in my website traffic after Google algorithm update on Fen 7, 2017. The traffic first witnessed a spike in last two weeks before update and then dropped suddenly day after the update. Used to get around 850 unique daily visits but the number of daily unique visitors to my site has now dropped to only 300+ after the update. Any suggestions or advice on how can I regain my lost traffic and loss in rankings would be highly appreciated and greatly welcomed.
Also the cpc rate of my google ad sense has witnessed a deep plunge from last 5-6 months. Any ways to improve cpc and make some decent money with ad sense?
