Hi, Recently I just ranked my site in under 2 months for bunch of keywords with good quality linkbuilding. My keywords are diversified for bunch of keywords. I was ranking #1 & #2 for bunch of keywords. Suddenly 1 Site overtakes me for all my keywords that was registered less than 1 week old and I beat him. I think the same guy used another brand new domain to beat me for all my keywords with another 2 week domain with no backlinks and no social shares. The sites only have 1 link 301 to the new site. They have been holding up for 1 & half week so far. I have been constantly linkbuilding with High PR and good quality links. How long do you think their sites will stay up or will I have to work to overtake the sites. Any suggestions guys.
