If I were to build my own search engine: - I'd make sure that multipurpose sites get lower ranks, ecommerce with a blog would get worse rank than a stand alone blog or an ecommerce. this would eliminate all the content marketing and owners would have to focus on their core business - I would put a cap on amount of content that increases rank. A website with a million recipes harvested from other sites won't be better than a blog with 10 quality recipes. - I would downgrade rank for use of third-party cookies, invasive ads etc. - I would give users an option to "mute" a website - Randomise top results to make sure no one can "occupy" top spots.
