There is no definite answer because there are many factors that can affect ranking, including how competitive your niche is, how optimized your competitors are, whether there are changes to the Google algorithm during the campaign, and how aggressively you want to invest in the strategy.  Even in the best-case scenario, advancing in the rankings doesn’t happen overnight. You can expect to see results anywhere between six months to a year. Your return on investment, however, makes this worth it– in that time, a business can get between $3 to $12 for every dollar spent on SEO, making local SEO packages a vital activity for a business to stay competitive.
