Recently heard that on April 21, 2015, Google will be implementing another important algorithm and it will measure website's mobile friendliness. It will even be a factor for website ranking. So, few questions coming into my mind and they are given below: 1 - how is this going to effect old sites without mobile version? 2 - What will be our strategies for making new websites for both small budget as well as large budget? 3 - How will the algorithm work and what will be our SEO strategies ? 4 - Any relation with content creation strategies ? 5 - Any relation with mobile apps marketing ? I want to hear from senior and experienced webmasters on this regard.
