Let's say you are trying to run a campaign on a website for 5 keywords. Is it better to try to squeeze in all the keywords somewhere on the homepage once or twice? Or to make separate pages where you write full articles utilizing the keywords multiple times with alt-tagged images and other content? Like website.com/keyword1, website.com/keyword2? Seems like a tradeoff to me because the homepage has a higher page rank than the sub-pages, but at the same time you can add more keyword related content and write the keyword multiple times on the sub-pages. So which is better?
