SEO vs paid ads: which costs less over two years?

The short answer

Paid ads cost less to start and stop working the day spend stops, while SEO costs more up front and keeps earning for years. In most models, content breaks even against paid traffic between months 9 and 18. The exact month depends on production cost, competition and refresh effort.

Key takeaways
  • Paid media is a rental, content is an asset.
  • Breakeven often falls in months 9 to 18.
  • Refresh content to slow decay.

A simple two-year model

Assume paid traffic costs $2.00 per visit and you need 5,000 visits a month, or $10,000 a month. Assume content costs $6,000 a month to produce and reaches 5,000 monthly visits by month 12, then holds with a 10% yearly refresh cost.

Cumulative paid spend reaches $240,000 by month 24. Content spend reaches about $150,000, with traffic continuing afterward.

What makes content slower

New sites need months to earn trust and rankings. Competitive terms take longer. Plan for a gap with no results in months 1 to 4.

Use both

Paid media gives fast learning and covers the gap. Content lowers blended cost over time. Many brands shift from 90% paid in year one to 60% paid in year two.

Refresh to keep the asset

Pages lose traffic as they age. A yearly refresh of the top 20 percent of pages keeps most of the traffic at a fraction of the original cost.
