How Long Does It Take for SEO Sites to Appear in SERPs?
If you are actively optimizing your site for Google (building backlinks, optimizing pages with meta, keywords etc.) - how long does it take for you to see the results?
it could be a few months...but it could be less too.as jiadany pointed out, its pretty much impossible to predict...I suggest keeping a record (of course) of how things go, but don't be too quick to make more changes until you have seen the site reach some sort of stability.
