HI BHW, I have been researching the last few months, planning and making notes to get into the world of SEO white/black. I have a few domain approx 30 - they are on 2 separate servers 1 godaddy ( I know, I was young and naive) the other a UK hosting company about 20 domains on the 1 IP at godaddy and 10 on the 1 IP with the UK server. How necessary is ti for me to have separate dedicated IPs for each site. i.e. I have 2 main sites (the rest are not set up) one on each server. If I run some white hat/black hat tests on the other sites, will the main sites be effected being on the same IP. If a test site gets sandboxed will that damage the main sites? any help would be appreciated.
