The verdict in three sentences
Cold prospecting is expensive and burns out; an SEO blog turns your site into a lead machine running 24/7. By targeting buying-intent queries ("how much does a site cost", "how to choose an agency"), you capture already-warm prospects. After 4-6 months of consistent publishing, the cost per lead drops 3 to 5x versus paid, and inbound converts 2x better because the prospect arrives already educated.
Which articles bring clients
Not all articles are equal. "Money" articles (bottom-funnel) attract buyers ready to purchase; "traffic" articles (top-funnel) build authority but convert little. A good mix favors transactional queries.
| Article type | Target keywords | Time to traffic | Leads/mo | Cost per lead | Closing vs outbound |
|---|---|---|---|---|---|
| "How much does an X site cost" | price, rate, cost | 3-4 months | 5-12 | ~4,000 FCFA | 2x |
| "How to choose an agency" | comparison, reviews | 4-6 months | 4-9 | ~5,000 FCFA | 1.8x |
| "X vs Y" (Wix vs custom) | tool comparison | 4-5 months | 3-8 | ~6,000 FCFA | 1.7x |
| Niche guide (restaurant site) | sector + city | 3-5 months | 3-7 | ~5,000 FCFA | 2x |
| Data-backed case study | results, ROI | 2-4 months | 2-6 | ~4,500 FCFA | 2.2x |
| Tutorial/definition | "what is" | 2-3 months | 1-3 | ~9,000 FCFA | 1.2x |

Inbound vs outbound: the 6-month math
| Channel | Monthly cost | Leads/mo (month 6) | Cost per lead | Closing rate |
|---|---|---|---|---|
| SEO blog (8-12 art./mo) | ~300,000 FCFA | 15-40 | ~10,000 FCFA then falls | 10-15 % |
| Meta/Google Ads | ~400,000 FCFA | 20-35 | ~15,000-25,000 FCFA | 5-8 % |
| Cold prospecting | sales time | 5-15 | high (time) | 3-6 % |
The blog requires patience (4-6 months to ramp) but becomes an appreciating asset: published articles keep bringing leads at no marginal cost, unlike paid which stops the moment the budget stops.
Mini case study
Sophie, founder of a small agency in Dakar, publishes 10 articles/month targeting "showcase site price", "Wave payment store", "Dakar restaurant site". By month 5, her blog generates 22 inbound leads/month. At 12 % closing, that is ~2.6 sales/month. On an average basket of 600,000 FCFA, that is ~1,560,000 FCFA/month in revenue, for a content production cost of 300,000 FCFA. Cost per lead: ~13,600 FCFA, falling every month as articles mature.

FAQ
How long before the first leads? Expect 3-4 months for the first transactional articles and 4-6 months for a steady flow of 15-40 leads/month. SEO is an asset, not an ad.
How many articles per month? 8-12 targeted articles are enough to build momentum. Consistency matters more than one-off volume.
Is the blog cheaper than Ads? Over time, yes: cost per lead falls each month because articles remain, whereas Ads restart from zero with every budget. Inbound also converts ~2x better.
Which articles prioritize closing? Buying-intent queries: "how much", "how to choose", "X vs Y", data-backed case studies. They attract buyers, not the curious.
What to do with surplus leads? Pass them via the Kolonell referral program (12-15 %) rather than letting them go cold. An untreated lead is a lost commission.
