Carlos, I agree with the others. If you are trying to get results today, then I would run a PPC campaign. If you can't afford PPC hen I would try to rank for some long tail keywords that have some traffic. Go for the low hanging fruit and as you build your website up you can rank for more competitive keywords later. Depending on your niche, I would also consider social ads. Hope this helps. One month to rank for most keywords isn't realistic but if you are consistently doing it right, you should see some traction sooner in a few months unless its ultra competitive. So go through the back door and look at some long tail keywords.
