Reduce CAC with SEO
Every customer you win organically is one you didn't pay a CPC for. We find the searches where organic can carry the load, move budget off them, and prove the drop in blended CAC.

“Your CAC climbs every quarter while CPCs climb with it.”
“Finance wants a lower CAC and the only lever anyone pulls is bids.”
“You've cut wasted keywords already. There's nothing obvious left.”
“You suspect SEO would help but can't size the opportunity.”
What we do
How much paid spend organic could carry, keyword by keyword.
A staged plan to move spend, with guardrails so revenue doesn't dip.
Content and technical SEO aimed at the terms your paid data shows convert.
Loyalty and lifecycle tactics that raise LTV, so the CAC you do pay goes further.
Blended CAC and payback, tracked against the baseline we set together.
Four numbers from your ad account. Nothing is saved or sent.
Your inputs
Formula: (spend × branded % × kept %) + (spend × (1 − branded %) × non-brand %). A rough estimate from four inputs, not a forecast.

I have been working with Social ToothPaste Agency for a few months now and I wholeheartedly recommend them. Their detailed support has been exceptional and has exceeded all of our expectations. I have worked with several marketing companies in the past, but none of them come close to the level of service provided by Social ToothPaste.

How do you calculate blended CAC?
Total sales and marketing acquisition spend divided by new customers in the period, across paid and organic. We agree the exact inputs with your finance team first.
How much can SEO lower CAC?
It depends on your branded share, overlap and market. The calculator gives a first estimate. The audit gives a real one.
How long does it take?
Overlap savings can show in weeks. Organic growth on new terms takes 3–6 months.
Is the calculator accurate?
It's a rough estimate from four inputs, and it shows its formula. Treat it as a reason to run the audit, not a forecast.
