Pick up the best-performing keywords, just do not think about high volume keywords, think about the keyword which are going to give you more business e.g. if your selling Luxury Holidays to different destination of the worlds choose Luxury Holidays Destination Name which have low volume of traffic with high conversion rate. And if you try to target keywords like “holiday to destination name (Mauritius)”, you will have high volume but low conversion rate and hard to achieve high ranking as well
