Sorry for the ignorant question. When does google updates it search ranking? If I do some SEO then google updates it cache, will it also update my rankings? Thanks as always.
1) Continuously whenever they feel like doing tweaks or major changes. 2) Not necessarily related to the cache update that shows but yes ranking will change whenever the algo changes. Or whenever the playing field changes, i.e. others coming in and leaving the SERPs. No monthly 'dance' no more.
It used to be a monthly update with big changes and only minor ones in between. The big change was/is referred to as the 'Dance'. It is a continuous thing now hence questions you see popping up like "Did you move ten places today too?!" are pointless IMO.
