On Page optimisation is what we do "ON" the pages - this is mostly to do with the content of the website - to create food for crawlers. On Page optimisation consists of a range of things that can be done on the website - this includes having a good and relevant title, writing relevant and meaningful content, optimisating non readable objects such as images among a range of thinsg.

This process could take days to weeks depending on the size of the website. This also includes site architecture analysis, content relevancy testing, content copywriting etc.
