I have a site with about 6 redirects going into it. It is sitting on number 7 on page 1 in UK and about halfway down page 2 in USA. I added another 2 301s about 3 days ago and it moved slightly,maybe 1 position up. Would it be ok to add another 301 at the moment or should I wait for a bit longer to see what happens? Also,with 301s,how often should you add them? Is 6 at the one time fine or should it be spaced evenly over a period of time?
