Measure success against your original goals. Set specific targets like “increase organic traffic by 30%,” “increase conversion rate from 1% to 1.5%,” or “generate 20 qualified leads per month.” Track metrics for 90 days after launch. Most sites see temporary ranking dips (3-7 days) then recover. If you’re not seeing improvement after 3 months, analyze what’s not working and make improvements. Compare year-over-year traffic, leads, and revenue 6-12 months after launch.
