Hi guys i have this site that i am trying to rank in slow and steady manner and for long term. Keyword search volume is over 10 million per month, i managed to get it top 30 within 3 months top 20 within 4-5 months, now its been 6 months and site is stuck at #11-12 for over a month. Since this is a white hat site(natural looking links) i am not using any public blog network, High PR links, i do buy guest posts from time to time and carefully select each blog... Site has like 100 referring domains so far, all very high quality sites, i made each link look as natural as possible... so my question is what is the safe link building to get it to top 5... not interested in public blog networks. I have made a private blog network of 10 blogs for this site, not planning to build more pbn links as i don't want to overdo any link building. My main anchor % is less then 15% .. Also i am not interested in any black/grey hat strategy since i want to rank this site for long term.. any advice from experienced members is appreciated.. thanks.
