Organic vs Paid Traffic Calculator
Compare the real cost of SEO/blog traffic versus paid ads over time — see your break-even month and cost per visitor.
Cost per visitor over the whole period: — with a blog vs — with ads. After you stop paying, ads traffic goes to zero — the blog keeps bringing visitors.
| Month | Blog visits/mo | Blog spent (total) | Ads to match (total) | Difference |
|---|
A simple model: ads cost = clicks × CPC every month; blog articles ramp to full traffic over the “months to rank” window and then keep working for free. Adjust the inputs to your numbers.
Organic vs paid traffic: which is cheaper?
Paid ads and SEO both bring visitors, but the cost curves are opposite. With ads you rent traffic: every visit costs you the cost-per-click, and the moment you pause the campaign the traffic stops. With a blog you build an asset: each article takes time to rank, but once it does it brings visitors month after month at (almost) no marginal cost. This calculator compares the two over time so you can see the break-even month and your real cost per visitor.
Early on, ads win — they deliver clicks instantly while your articles are still climbing the SERP. But content compounds: as your library grows and matures, your organic traffic keeps rising while your spend stays flat. Somewhere along the way the blog overtakes ads on cost per visitor, and every month after that the gap widens. The visitors you would have kept renting from Google Ads now come for free.
Why the blog keeps paying off
An article that ranks on page one can hold that position for years, driving traffic long after it was written. Add internal links and topical depth and each new post lifts the others. That is the compounding effect ads simply do not have — which is why the smartest play is usually ads for immediate demand plus a blog for durable, cheaper traffic underneath.
FAQ
Is SEO really cheaper than ads?
Over a long enough horizon, almost always. Ads cost the same per click forever; blog content has an upfront cost and then keeps delivering traffic for free, so the cost per visitor falls the longer you run it.
How long until a blog beats ads?
It depends on how fast your articles rank and how much you publish, but the break-even often lands within the first year — typically 3 to 12 months. This calculator estimates it from your inputs.
Should I do both?
Yes — ads capture demand today while your blog builds durable, low-cost traffic. The goal is to shift more of your traffic to the cheaper organic channel over time.
