Service-Business Search Lead Economics

The chart shows the nine nonblank Google Ads average CPC fields in the DataForSEO Labs Google Keyword Overview pull, sorted from highest to lowest. CPC is paid-search market context. It is not cost per lead, customer value, an SEO price, or an outcome forecast.

The retained budget estimator applies Foundgrove's own published prices and internal scope bands. Its industry adjustment is a Foundgrove estimator assumption only—not a vendor benchmark, a CPC-derived price, or a quote.

The calculator applies the following equations in order. Google Ads Help defines ROI as a ratio of net profit to cost and recommends assigning conversion values that match a business's real objectives; this page uses gross profit per customer as the value input rather than importing a market benchmark.

1. Leads = high-intent visits × visitor-to-lead rate.
2. Customers = leads × lead-to-customer rate.
3. Gross profit = customers × gross profit per customer.
4. Net return = gross profit − monthly marketing cost.
5. ROI = net return ÷ monthly marketing cost × 100. At zero cost, ROI stays undefined.
6. Break-even cost per lead = gross profit ÷ leads. At zero leads, the result is zero.

The full Foundgrove assumption table the budget estimator draws from. Service area sets the row; law, dental, and med spa use the adjacent planning row under the estimator's disclosed internal classification:

A site that needs rebuilding adds $8,500–$25,000 one-time — Foundgrove's published fixed-fee range for a conversion-focused build. The estimator selection does not establish that a specific site needs a rebuild; that requires a scope review.

Monthly retainers are the dominant model — 78.2% of SEOs charge one, per Ahrefs' survey of 439 SEO providers. What that retainer costs varies by who you hire and where they are:

"SEO costs usually range from $250 to $10,000 per month, with most businesses (63%) spending between $500 and $5,000."

Two caveats worth knowing: US-based services cost 3–5x more than providers in emerging markets (Backlinko), and SE Ranking's authors note their 260-agency sample may not reach statistical significance — treat every survey band as a range, not a rule.

The pricing itself tells you how an engagement will go. Five patterns to walk away from:

1. A guaranteed ranking attached to a price. Nobody controls Google; a guarantee is a sales device, not a deliverable.
2. A long lock-in with vague monthly scope. The compared rate cards above show month-to-month exists at every price point — a 12-month contract with undefined deliverables shifts all the risk to you.
3. The agency keeps your assets. If content, the site, or the Google Business Profile stays theirs when you leave, the retainer was rent, not investment.
4. Reporting that stops at rankings. A report that never reaches calls, forms, and booked work is priced against the wrong outcome.
5. A price with no scope attached — in either direction. Backlinko's own red-flag list includes unusually cheap pricing relative to other quotes (Backlinko); a number that can't explain what ships each month is a red flag at $500 and at $5,000.
