Im trying to figure out how aggressive I can be with my link building for my offline business. The competition doesn't have much backlinks and there isn't alot of monthly searches for city+service. Maybe 1000 with all of the combinations combined. I am currently in the middle of page one and want to get to top but dont want to trigger a penalty. So im wondering if your competition doesnt have alot of links and the monthly searches is low and you build alot of links will this trip off a penalty. Does G use a %formula for this you think?
