I am ranking in the 1st position of Google SERP for highly competitive Keyword in my niche. After getting 1st position I stopped doing promotional activities for that respective keyword then its dropped to 3rd position.
So now my question is when a site is in 1st position for a particular keywords should i still do promotional activities for that respective keyword?
or what factors should i look in to in my site with respective that keyword to stay longer time in that serp. position
