lets say i have a good long tail keyword blog. i write 5 keyword optimized articles then put them on a rotation that has 3 of them published at any given time and 2 of them not visible. ex. day 1: article a, b & c day 2: article b, c & d day 3: article c, d & e so on and so forth until the sun swallows the earth or robots take over (bow down to your g00gle overlord) Obv not intended for return human visitors, but will the spiders see this as an updating blog. Would appreciate any comments if you see any seo problems with this concept. oh and any rotation plugins that work well for blogger, squidoo or wp would be really helpful.
