If your doing something fitness related I would create an Instagram account. Provide specific practical tips/ how to information- information that would get your ideal client a result without needing you- you'll be able to curate a feed and look book that makes sense to your target customer -- then start engaging with hashtags and keywords that are being used them. So much more traffic you can attract from a platform that has 600 million users than worrying about SEO on a daily basis.
