Apart from taking care of domain age, structure / technical shizzle etc. This technique works out quite well for my clients:
---> blog 3 times a week - at least - regularly - and don’t limit your blogs to your product or service only, make sure you understand your target group first
---> buy FB traffic to promote your blogs and get it that little push
Do be sure that you approach your techniques project wise. Keep TRACK of them by benchmarking your current positions on specific keywords. Don’t expect growth in the first few weeks. In the end it’s ALWAYS a long term, expensive project.
