SEO *must* be kept in mind

This is not a factual website - you must possess experience in writing in such a way that is engaging and leads to sales

This is a comparison website - so it is important that the user is drawn to the content and is inclined to click on the call to action

This is for a niche startup - so some research may be required.
Extensive research needed: yes
