Most marketing agencies charge $1,500-$5,000 per month for SEO services, with the average small business retainer at $3,000/month ($36,000/year). The $20 Dollar Agency shows you how to do the same work using a $20/month AI subscription and free tools like Google Search Console, Google Analytics 4, and Microsoft Clarity.
A healthy SEO ROI is 500-1,000% or higher. If you're spending $3,000/month on an agency, you should be generating at least $15,000-$30,000/month in organic revenue to justify the cost. With DIY SEO at $20/month, even $200/month in organic revenue gives you a 900% ROI.
It depends on your average customer value. At $3,000/month agency cost and a $100 average customer value, you need 30 new customers per month just to break even on the agency fee alone. At $20/month DIY cost, you break even with 1 customer. Use the calculator above to see your specific numbers.
