Chapter 39 — Exercises

Work these in order; they climb from recall to judgment. Items marked † get full worked solutions in the answers appendix. No answers here — struggle first. Every dollar and percentage below is illustrative, as in the chapter. Where a task says "your own site," use Appendix C's worksheet.

Recall

39.1 † State the SEO ROI identity in full — the four multiplied factors that produce organic value, and the ratio that produces ROI — and define each factor in one sentence.

39.2 Define, in one sentence each: traffic forecast, CTR curve, break-even, opportunity cost, compounding returns.

39.3 Why does "value per conversion" change depending on whether you use first-transaction value or customer lifetime value? Which should a conservative business case use, and why?

39.4 Name the main cost categories in an SEO budget. Which category is usually the largest, and which is largely a one-time cost?

39.5 Explain the difference between an expense and an asset, and state which SEO more closely resembles — with the one caveat that keeps the claim honest.

39.6 In plain language, what does the shape of the CTR curve imply about the practical difference between ranking #3 and ranking #11?

Applied reasoning

39.7 † A page targets a term with 1,500 monthly searches, currently at a position earning about 1.6% CTR, with a target position earning about 7% CTR (illustrative). (a) Forecast the incremental monthly visits. (b) If those visits convert to a lead at 4%, leads close at 50%, and a job is worth \$500, what is the incremental monthly organic value at the target run rate? Label your figures illustrative.

39.8 Explain why the sum of a keyword forecast — not any single optimistic row — should carry a business case.

39.9 A CFO says, "If we want more customers from Google, why not just buy ads?" Give the honest three-part answer: one thing paid does better, one thing SEO does better, and why the mature answer is usually both.

39.10 † Compute a simple first-year SEO ROI given incremental revenue of \$135,000** against a cost of **\$83,000. Then explain, in one sentence, why this figure likely understates the true return.

39.11 Why is SEO's cost per acquisition (CPA) high in year one but falling thereafter, while paid search's CPA stays roughly flat forever? Tie your answer to "you stop paying, it stops" versus "you built an asset."

39.12 Describe the "valley of doubt" on the SEO J-curve and explain why it is where most programs are killed.

39.13 † In three sentences, reframe SEO from expense to asset for a skeptical owner — then concede the one place the asset framing breaks down.

39.14 Give two concrete mitigations for algorithm-dependence risk, and explain why doing only white-hat work is itself a form of risk management.

Diagnose

39.15 † A Rivertown service page is fully indexed and technically healthy, but it sits at #12 for its target term and drives no bookings. Walk through what you would check to decide whether it is worth building a business case around — and state clearly what a business case can and cannot promise about this page. (Draw on Chapters 1, 3, 9, and 38.)

Audit your own site

39.16 † Using Google Search Console (free), pull your own CTR-by-position numbers for five queries where you rank near #3 and five where you rank near #9. Compare them with this chapter's illustrative CTR table. What differs, and why should you forecast with your numbers rather than borrowed ones?

39.17 Pick three keywords relevant to your site. Record each one's search volume, keyword difficulty, and CPC (Chapter 7 tools). Now rank them for inclusion in a business-case forecast by opportunity (value × winnability), not by volume — and justify the ranking.

Optimize / rewrite

39.18 † Rewrite this pitch opening so it leads with business outcome instead of tactics: "We'll improve your title tags, fix your canonicals, add schema markup, and boost your Core Web Vitals scores." Then explain what you changed and why.

Read the report

39.19 † A forecast shows +168 visits/mo from an informational term (2,400 volume) and +70 visits/mo from a commercial term (720 volume). Which belongs higher in the business case, and why is the higher-traffic term not necessarily the higher-value one?

39.20 † You are handed an agency report claiming "SEO delivered a 412% ROI last quarter." List three questions you would ask before believing the number, and name the two inputs most likely to be inflated.

Spot the myth

39.21 "SEO is free traffic." Identify the myth precisely and state what is actually true.

39.22 † "We invested in SEO last year, so we're set — we can cut the budget to zero this year." Spot the myth and state the truth, tying it to content decay and the platform.

Ethics and risk judgment

39.23 An agency guarantees "#1 rankings or your money back" and "a 300% ROI, guaranteed." What is wrong with this, both factually and ethically? What would an honest pitch promise instead?

39.24 † A client insists on a 90-day trial before committing to anything longer. Explain why simply agreeing, as-is, arguably works against the client's own interests — and how you would restructure the arrangement honestly.

39.25 You must present an ROI figure to a board. The real number is a modeled range with substantial uncertainty. Is it honest to present a single confident number? Give the honest alternative and explain why it is more persuasive, not less.

Rivertown Strategy-File extensions

39.26 † Write a 30-second, one-paragraph version of Rivertown's business case addressed to Marisa and Tony Delgado — the version a busy owner actually reads. Use the chapter's illustrative figures, and open with money, not tactics.

39.27 Rivertown's Millhaven branch is newly opened and needs booked jobs this quarter. Recommend a paid-versus-SEO mix for Millhaven specifically, and justify it in ROI and timing terms.

39.28 † Draw Rivertown's cost-versus-return ramp and mark the break-even point. Then explain, in the owners' language, why the month-four review will look "disappointing" and why that is expected rather than a sign of failure.

39.29 Add the customer-lifetime-value lens to Rivertown's case: recompute the annual value of the "ac repair rivertown" page using CLV (~\$2,500/customer) versus first-job value (~\$700), and explain which figure you would put in the pitch and which you would hold in reserve.

Synthesis

39.30 † Explain how Chapters 7, 28, and 29 each supply one input to the ROI identity or one part of the business case. Be specific about which chapter owns which number.

39.31 A competitor is investing heavily in local SEO across the five-city metro while Rivertown is not. Make the opportunity-cost argument to the owners in money terms — what does not investing cost, and why might reclaiming lost ground later cost more than leading now?

39.32 † Under what circumstances would you honestly advise a business not to invest in SEO, or to invest in paid search first? Give at least three specific situations, and explain the reasoning in each.
