So let's say I have a primary wordpress site with over 300 articles, dates removed etc and it's only ranking on page 5 of google. The site focuses on a specific market. Now, if I copy all of the files for the site from my server and upload them all to 20 other domain names I don't care that much about, but I leave them all using the same database/content, in other words all of the links on these other 20 domain names actually take you back to to main domain that looks identical. Then, let say I use some of these churn and burn services for 50k back links etc for each of these other domains, one at a time...so, I use one, pump it, it get hit by Google, onto the next one and so on. how would this ultimately affect my primary website?
