Hi guys, For months now i've been #1 for 2 keywords. They bring me in a lot of visitors and money each day. A major voucher code site with DA of 65 and the specific page im in competition with has a PA of 39 and PR 2. My site has DA 21, PA 31 and 0 PR. I've not used any black hat tactics and havent bought any links. I've been aware of this site for a while but honestly havent kept track of where they have been ranking. They're out ranking me on a few lower volume related and LSI terms. They overtook me on these terms yesterday. This is what made me look into comparing all my keywords against theres. For pretty much all the lower volume words they're out ranking me for Im in position 1 for keyword 1 and 2 and they are in position 2 for keyword 1 and 2. Keywords 3 and 4 (also big volume words) im ranked 2 (site number 1 i have no idea how they're ranking as their backlink profile is full of viagra anchors from foreign sites) The big voucher code site ranks as number 3 for keywords 3 and 4. Im at a loss as to what i should do as i want to secure my ranking position and not be overtaken. My link building to date has been web 2.0 tiered link building (all manual done by myself) with tiers 2 and 3 being done in GSA. Some article directories. Forum posts. Manual relevant blog commenting. I've recently started carrying out interviews with other sites in my niche in an effort to get backlinks from those. What should i be looking at doing? I'd really appreciate any and all help guys. Im relying on this money to invest in a 'bricks and mortar business' and i was also considering selling my site. Now im worried that i'll get outranked, my earnings will drop and i wont be able to make the money i need or sell the site for as much as what i had anticipated. Thanks guys.
