As 301s are really effective in passing link juice, would like to use them to complement my PBNs. For now, have some questions regarding 301s: Do have several niche relevant domains that are of great quality on standby. Hence, is it advisable to do 301s from multiple (say 3 or 4) domains? Are competitors able to report 301s to Google (possibly resulting in a penalty) the same way in which they do for PBNs? Is blocking crawlers (eg. ahrefs) using htaccess going to prevent them from detecting my 301? If not, is there any way to stop them? As there is a domain that I'm considering using as my money site in the future, is it advisable to do a 301 for now and interchanging (i.e it becomes the money site, and my current money site will be 301ed to this particular domain) when the time is right? Thanks in advance for any advise in these areas.
