I've starting my link building myself, my website is 4 years old and has 550 referring domains according to majestic. I've been using different seo firms since the site launched, they've never given us results and judging by the data they haven't been doing a lot. in the past year it says we've gained 20 - 40 referring domains each month, most months closer to 20, in December i started and built 80 new referring domains links through out the month. i want to start building as many links as possible of decent quality without raising flags in google would it be ok for me to build roughly 200 links in January 300 links in February 400 links in March 500 links in April and so on. would i be risking getting sand boxed? can i build more links every month e.g. 200 - 400 - 600? should i stop being a pussy and build 500 links this month and improve from there? i'm playing catchup with the competition who build about 200 links a month and are 3000 referring domains in front. As this site brings me most my sales i can't risk it disappearing for a couple weeks or worse!
